A/D type with LCD Mask 8-bit Microcontroller - HT46C63

September 10, 2002

Following the recent release of the HT46R63 OTP microcontroller, Holtek is now pleased to announce the release of its fully compatible Mask version device, the HT46C63. Designed for high volume low cost applications the HT46C63 is a further new generation MCU addition to the range of A/D with LCD type microcontrollers. With its 4K of internal OTP memory and 32 I/O pins, it allows for easy interfacing to devices such as external keypads and is also capable of directly driving LEDs. The device is also capable of controlling external power components such as triacs or relays etc. Its internal 8-channel A/D converter can directly monitor external analog signals such as those used by battery monitors, current measurements, temperature measurements, etc as well as many other types of sensor signals. The device's internal 4-channel 8-bit PWM D/A converter can be utilised to control external electronic devices or equipment such as that used for temperature, speed, voltage and other industrial or consumer devices. Its integrated 19x4 LCD driver internal circuitry, two oscillator circuits and one comparator circuit add to the already comprehensive features and demonstrate the flexibility and powerful capabilities of this device.

Conforming to industrial specifications, the HT46C63 has a working voltage range of 2.2~5.5V, a voltage range giving it applications in a wide range of consumer and industrial related products incorporating LCD panels such as water heaters, ovens, microwave, induction hotplates, heating stoves, to mention only a few. Additional applications could be traditional and digital cameras, vehicle clocks, electric bicycles, exercise machines and other leisure related products.
