08/26/2011

Holtek is delighted to announce the release of its new Enhanced A/D type MCU, the HT46R0664. Including an embedded 12-bit A/D converter and 8-bit PWM, the HT46R0664 greatly reduces the need for peripheral components, reduces PCB areas and consequently reduces costs. With an accurate fully internal system frequency oscillator and an internal R-Type LCD driver, this new device is suitable for use in applications such as household appliances which include an LCD as part of their product function.

The special features of the HT46R0664 lie in its industrial quality specifications
(-40~85°C), operating voltage of 2.2~5.5V, internal R-type LCD driver, multi-function I/O pins, high speed 12-bit A/D converter, PWM function, internal RC oscillator, power-down and wake-up functions, high and low dual frequency dynamically switchable system clock operation as well as RTC function etc, This comprehensive range of functions combine to offer a highly competitive MCU with superior functions, characteristics and competitive pricing. The HT46R0664 will see excellent use especially in the small household appliance application area, for products such as electric hobs and food processors to name but a few. Presently, market attention is much focused on devices with superior cost/function ratios and in this regard the device is well equipped to provide an excellent MCU solution to meet the needs of the modern household appliance application area.

Along with other Holtek 8-bit MCUs, this new device has a full array of protection features including high noise immunity, watchdog timer and low voltage reset to provide maximum protection against erroneous operation.
