HT49R10A-1/HT49C10-1 -- LCD Type 8-Bit MCU

General Description

The HT49R10A-1 is an 8-bit, high performance, RISC architecture microcontroller devices specifically designed for a wide range of LCD applications. The mask version HT49C10-1 is fully pin and functionally compatible with the OTP version HT49R10A-1 device.

The advantages of low power consumption, I/O flexibility, programmable frequency divider, timer functions, oscillator options, power-down and wake-up functions and buzzer driver in addition to a flexible and configurable LCD interface, enhance the versatility of these devices to control a wide range of LCD-based application possibilities such as measuring scales, electronic multimeters, gas meters, timers, calculators, remote controllers and many other LCD-based industrial and home appliance applications.

The HT49C10-1 is under development and will be available soon.
