Holtek HT67Fxx TinyPowerTM A/D with LCD type Flash MCU Series

Holtek » HT67F30, HT67F40, HT67F50, HT67F60

Holtek is delighted to announce the release of its new 8 bit TinyPowerTM A/D with LCD type Flash MCU series. This device series includes the full feature range of the Enhanced Flash MCUs while also incorporating Holtek’s unique TinyPowerTM technology. With its ultra low power consumption, fast wake-up, multiple clock sources and range of operating modes that greatly reduces power requirements, this new device range is positioned to meet the demands of today’s environmentally conscious products. The device range is suitable for applications such as household appliances, instrumentation products, industrial control, health products, exercise equipment etc.

Holtek: HT67Fxx Flash Memory A/D with LCD type 8-bit high performance MCU

The HT67Fxx series is composed of four MCU devices (HT67F30, HT67F40, HT67F50 and HT67F60) encompassing a full range of multiple functions. These include a core with 2K~12K word of Flash Program Memory, 128~640 bytes of Data Memory, 64~256 bytes of Data EEPROM and 4~12 stack levels. Regarding peripheral functions, all devices contain an internal R-type and power-efficient C-type LCD driver to support applications with display requirements. The internal 12-bit high speed analog to digital converter is on hand to measure external environmental signals from sensors such as temperature, humidity etc. An internal comparator and two independent SPI and SPI/I2C interfaces are also included while the whole series use Holtek’s new Timer Modules offering five different timer operating modes, namely Input Capture, Compare, Timer/Event, Single Pulse Output and PWM. These features combine to offer a device series that can implement a full MCU system with a minimum of external components.
