Holtek releases 16-lead high noise immunity MCUs

Holtek has released a new 16-lead high noise immunity device range, the HT48R01x and HT46R01x. The HT48R01x series contains HT48R016 and HT48R017 while the HT46R01x series contains HT46R016 and HT46R017. The HT46R01x devices include an embedded 12-bit A/D converter and an 8-bit PWM generator, functions which decrease the necessity of peripheral components. Their precision internal system frequency oscillator makes these new devices suitable for use in applications such as small household appliances.

Some of the characteristics of the HT48R01x and HT46R01x can be seen in their industrial quality specifications (-40~85C), operating voltage range of 2.2V~5.5V, multi-function I/O pins, high speed 12-bit A/D converter, PWM function, internal RC oscillator, power-down and wake-up functions. This broad range of features together provides a new range of highly competitive MCU devices with superior functions and characteristics. These two new device ranges can be used in hair care products, electronic hobs, electric fans, food processors, chargers, vacuum cleaners etc.

As is the case with other 8-bit Holtek MCUs, these new devices have high noise immunity as well as Watchdog and LVR protection features that give good immunity against malfunction or erroneous operation. The whole series is supplied in 16-pin DIP and NSOP package types.
