The multiple functions within this new device extensively reduce the need for peripheral components, resulting in the added benefits of reduced PCB size and cost. Its precision internal system frequency oscillator and integrated direct-drive R-type LCD driving circuit further add to these features making the device suitable for use in applications such as small household appliances and LCD panel display products.

Some of the special characteristics of the device can be seen in its industrial quality specification (-40°C~85°C), operating voltage range of 2.3V~5.5V, OTP Program Memory capacity of 2K words, SRAM Data Memory capacity of 96 bytes, multi-function I/O pins, integrated R-type LCD COMs, high speed 12-bit A/D converter, PWM function, internal high precision RC oscillator, power-down and wake-up functions.

All these features make the device a competitive MCU with regard to functions, performance and price. This new device will see excellent use in the household appliance area such as hair care products, cooking appliances, electric fans, blenders, chargers, vacuum cleaners etc. Presently, market attention is strongly focused on devices with excellent price/performance ratios, and in this respect this new Holtek device conform well, giving it 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, this new device has high noise immunity as well as Watchdog and LVR protection features that give excellent immunity against malfunction or erroneous operation. This device is supplied in 20-pin DIP/SOP/SSOP and 24-pin SKDIP/SOP/SSOP package types.
