Motorola 68HC16
The 68HC16 (also abbreviated as HC16) is a highly modular microcontroller family based on the CPU16 16-bit core made by Freescale Semiconductor (formerly known as Motorola Semiconductor). The CPU16 core is a true 16-bit design, with an architecture that is very familiar to 68HC11 (HC11) users. The resemblances to the HC11 core design are a deliberate move to provide an upgrade path for those 8-bit 68HC11 designs that require the increased power of a 16-bit CPU. Many features of the HC16 and the CPU16 core are new to HC11 users. The HC16 provides a software upgrade path for HC11 users while giving full hardware compatibility with the asynchronous address and data bus found on the 32-bit microprocessors A microprocessor is a computer processor where the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circu .... External linksHC16 Overview< ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freescale 68HC12
The 68HC12 (6812 or HC12 for short) is a microcontroller family from Freescale Semiconductor. Originally introduced in the mid-1990s, the architecture is an enhancement of the Freescale 68HC11. Programs written for the HC11 are usually compatible with the HC12, which has a few extra instructions. The first 68HC12 derivatives had a maximum bus speed of 8 MHz and flash memory sizes up to 128 KB. Architecture of the 68HC12 Like the 68HC11, the 68HC12 has two 8-bit accumulators A and B (referred to as a single 16-bit accumulator, D, when A & B are cascaded so as to allow for operations involving 16 bits), two 16-bit registers X and Y, a 16-bit program counter, a 16-bit stack pointer and an 8-bit Condition Code Register. Unlike the 68HC11 the processor has 16bit internal data paths The 68HC12 adds to and replaces a small number of 68HC11 instructions with new forms that are closer to the 6809 processor. More significantly it changes the instruction encodings to be far ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freescale 68HC11
The 68HC11 (6811 or HC11 for short) is an 8-bit microcontroller (µC) family introduced by Motorola in 1984. Now produced by NXP Semiconductors, it descended from the Motorola 6800 microprocessor by way of the 6801. The 68HC11 devices are more powerful and more expensive than the 68HC08 microcontrollers, and are used in automotive applications, barcode readers, hotel card key writers, amateur robotics, and various other embedded systems. The MC68HC11A8 was the first microcontroller to include CMOS EEPROM. Architecture Internally, the HC11 instruction set is backward compatible with the 6800 and features the addition of a Y index register. It has two eight-bit accumulators, A and B, two sixteen-bit index registers, X and Y, a condition code register, a 16-bit stack pointer, and a program counter. In addition, there is an 8 x 8-bit multiply (A x B), with full 16-bit result, and fractional/integer 16-bit by 16-bit divide instructions. A range of 16-bit instructions treat the ...

Freescale 68HC08
The 68HC08 (HC08 in short) is a broad family of 8-bit microcontrollers originally from Motorola Semiconductor, later from Freescale Semiconductor. HC08's are fully code-compatible with their predecessors, the Motorola 68HC05. Like all Motorola processors that share lineage from the 6800, they use the von Neumann architecture as well as memory-mapped I/O. This family has five CPU registers that are not part of the memory. One 8-bit accumulator A, a 16-bit index register H:X, a 16-bit stack pointer SP, a 16-bit program counter PC, and an 8-bit condition code register CCR. Some instructions refer to the different bytes in the H:X index register independently. Among the HC08's there are dozens of processor families, each targeted to different embedded applications. Features and capabilities vary widely, from 8 to 64-pin processors, from LIN connectivity to USB Universal Serial Bus (USB) is an industry standard that establishes specifications for cables, connectors and p ...

Motorola 68HC05
The 68HC05 (HC05 in short) is a broad family of 8-bit microcontrollers from Freescale Semiconductor (formerly Motorola Semiconductor). Like all Motorola processors that share lineage from the 6800, they use the von Neumann architecture as well as memory-mapped I/O. This family has five CPU registers that are not part of the memory: an 8-bit accumulator A, an 8-bit index register X, an 8-bit stack pointer SP with two most significant bits hardwired to 1, a 13-bit program counter The program counter (PC), commonly called the instruction pointer (IP) in Intel x86 and Itanium microprocessors, and sometimes called the instruction address register (IAR), the instruction counter, or just part of the instruction sequencer, is ... PC, and an 8-bit condition code register CCR. Among the HC05's there are several processor families, each targeted to different embedded applications. The 68HC05 family broke ground with the introduction of the EEPROM-based MC68HC805C4 and MC68HC80 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hitachi 6309
The 6309 is Hitachi's CMOS version of the Motorola 6809 microprocessor, released in late 1982. It was initially marketed as a low-power version of the 6809, without reference to its many internal improvements. While in "Emulation Mode" it is fully compatible with the 6809. To the 6809 specifications, it adds higher clock rates, enhanced features, new instructions, and additional registers. Most of the new instructions were added to support the additional registers, as well as up to 32-bit math, hardware division, bit manipulations, and block transfers. The 6309 is generally 30% faster in native mode than the 6809. This information was never published by Hitachi. The April 1988 issue of ''Oh! FM'', a Japanese magazine for Fujitsu personal computer users, contained the first description of the 6309's additional capabilities. Later, Hirotsugu Kakugawa posted details of the 6309's new features and instructions to comp.sys.m6809. This led to the development of NitrOS-9 for the Ta ...

Psion Organiser
Psion Organiser was the brand name of a range of pocket computers developed by the British company Psion in the 1980s. The Organiser I (launched in 1984) and Organiser II (launched in 1986) had a characteristic hard plastic sliding cover protecting a 6×6 keypad instead of a computer keyboard, with letters arranged alphabetically. The Organiser II competed with the Filofax and can be considered the first usable electronic organizer or personal digital assistant (PDA) in that it combined an electronic diary and searchable address database in a small, portable device. Production of consumer hand-held devices by Psion has now ceased; the company, after corporate changes, now concentrates on hardware and software for industrial and commercial data-collection applications. On an episode of ''The Gadget Show'', first aired 30 March 2009, the Psion was pitted against the BlackBerry for a place on the show's Hall of Fame. Whilst the Psion was highly praised as a device that pioneere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 6809
The Motorola 6809 ("''sixty-eight-oh-nine''") is an 8-bit microprocessor with some 16-bit features. It was designed by Motorola's Terry Ritter and Joel Boney and introduced in 1978. Although source compatible with the earlier Motorola 6800, the 6809 offered significant improvements over it and 8-bit contemporaries like the MOS Technology 6502, including a hardware multiplication instruction, 16-bit arithmetic, system and user stack registers allowing re-entrant code, improved interrupts, position-independent code and an orthogonal instruction set architecture with a comprehensive set of addressing modes. Among the most powerful 8-bit processors of its era, it was also much more expensive. In 1980 a 6809 in single-unit quantities was compared to for a Zilog Z80 and for a 6502. It was launched when a new generation of 16-bit processors were coming to market, like the Intel 8086, and 32-bit designs were on the horizon, including Motorola's own 68000. It was not feature competitiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorola 6808
The 6800 ("''sixty-eight hundred''") is an 8-bit microprocessor designed and first manufactured by Motorola in 1974. The MC6800 microprocessor was part of the M6800 Microcomputer System (latter dubbed ''68xx'') that also included serial and parallel interface ICs, RAM, ROM and other support chips. A significant design feature was that the M6800 family of ICs required only a single five-volt power supply at a time when most other microprocessors required three voltages. The M6800 Microcomputer System was announced in March 1974 and was in full production by the end of that year. "Motorola's M6800 microcomputer system, which can operate from a single 5-volt supply, is moving out of the sampling stage and into full production." The small-quantity price of the MC6800 is . The MC6820 PIA cost . The 6800 has a 16-bit address bus that can directly access of memory and an 8-bit bi-directional data bus. It has 72 instructions with seven addressing modes for a total of 197 opcodes. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
