Holtek's design focus is in the area of microcontroller development.
Holtek's 32-bit series is based on ARM
Cortex-M0+ and
Cortex-M3 cores. They are also producing
8051
The Intel MCS-51 (commonly termed 8051) is a single chip microcontroller (MCU) series developed by Intel in 1980 for use in embedded systems. The architect of the Intel MCS-51 instruction set was John H. Wharton. Intel's original versions were po ...
based controllers, but the majority of their 8-bit microcontrollers are based on a core designed in-house that is very similar to the
Microchip PIC16 architecture. All have common features such as timers, external interrupts, power-down functions, low-voltage reset, bi-directional I/O pins etc. The range of microcontrollers support clock speeds from 32 kHz up to 20 MHz. Device specific features include functions such as EEPROM memory, A/D converters, LCD interfaces, USB interfaces, operational amplifiers. Some of Holtek's 8-bit and 32-bit microcontroller devices:
* HT32F51XX ARM M3 core based 32-bit series
* HT85F22XX 8051 core based 8-bit series
* HT46RXX A/D type series
* HT46FXX Flash A/D type series
* HT48RXX I/O type series
* HT48FXX Flash I/O type series
* HT49XX LCD type series
* HT56RXX Tiny Power A/D type series
* HT66FXX Flash A/D type series
* HT68FXX Flash I/O type series
* HT82XX Computer Peripheral series
* HT95XX Telecom Peripheral series
* BS8XXX Touch IC series
Holtek develops other devices, most of which could be classified as microcontroller peripheral devices. One area is that of Low Dropout Regulators where Holtek has provided a range of products with low supply currents. Holtek supports traditional products such as remote control and telecommunication devices. Some peripheral products include:
*HT7XX Power Management Devices
*HT93X/24X Memory Products
*HT12X Remote Control Devices
*HT16XX Display Drivers
*HT9XX Telecom Peripherals
Holtek Semiconductor devices are used in home appliances, computer
peripheral equipment, home medical equipment market. The company also provides a design service for customers with specific microcontroller needs. These special microcontroller devices may integrate functions such as smart card interface or medical analog circuitry within the microcontroller.
Development tools
Holtek also supplies its IDE-3000 development system to support its microcontroller devices. This is a suite of hardware and software development tools which includes real time hardware emulation and software simulation as well as tools for device programming of OTP and flash type devices. Some of Holtek's ICE In-Circuit Emulators also include an integrated device programmer eliminating the need for separate programming tools. The separate programming tools can be operated in a stand-alone mode without a PC connection.
