08/15/2011

Holtek wishes to announce the release of its new HT48R06xB and HT46R06xB series devices. The HT48R06xB series contains four devices, namely the HT48R063B, HT48R064B, HT48R065B and HT48R066B while the HT46R06xB series contain three devices, namely the HT46R064B, HT46R065B and HT46R066B. The HT46R06xB, embedded with an internal 12-bit A/D and 8-bit PWM, can extensively reduce the need for peripheral components and bring with it the added benefits of reduced PCB size and cost. Their precision internal system frequency oscillator and direct-drive R-type LCD driver function make these new devices suitable for use in applications such as small household appliances which may include an LCD as part of their product function.

Some of the special characteristics of the HT48R06xB and HT46R06xB can be seen from their industrial quality specifications (-40~85℃), operating voltage range of 2.2V~5.5V, internal R-Type LCD COM, multi-function I/O pins, high speed 12-bit A/D converter, PWM function, internal RC oscillator and power-down and wake-up functions. Their high and low dual operating frequencies can be dynamically switched using the application program. All devices also include a real time clock for precision timing operations. This comprehensive range of features together offers a new range of highly competitive MCU devices with superior functions and characteristics. These two new device ranges will see excellent use in areas such as household appliances within which could include hair straighteners, electronic hobs, electric fans, food processors, chargers, vacuum cleaners etc. to name only a few. Presently, market attention is much focused on devices with good price/performance ratios, and in this respect these new Holtek devices conform well, giving them the capabilities to provide excellent MCU solutions to meet the needs of the modern household application area.

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 excellent immunity against malfunction or erroneous operation. The whole series is supplied with a wide range of package types from 16 to 28 pins.
