Holtek Semiconductor Intros HT47C10L Microcontroller

Holtek Semiconductor Inc. (Taiwan) introduced its new HT47C10L eight-bit microcontroller, which operates from 1.2V to 2.2V and is designed for use over the -40 to +85 degrees C temperature range. The new microcontrollers are suitable for battery-powered applications, or for use as heat and humidity controllers and tire pressure gauges.

The 44-pin QFP device features 1KB of mask program memory, 32 bytes of RAM, a 4 x 9 LCD display driver, and an EO backlight driver. It also has a built-in, resistance-to-frequency converter that converts the resistance (or capacitance) value of an external thermistor (or variable capacitor) to a frequency value, which can then be used for control or display operations.
