General Description
The HT49R10A-1 is an 8-bit, high performance, RISC
architecture microcontroller devices specifically de-
signed for a wide range of LCD applications. The mask
version HT49C10-1 is fully pin and functionally compati-
ble with the OTP version HT49R10A-1 device.
The advantages of low power consumption, I/O flexibil-
ity, 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 ap-
plication possibilities such as measuring scales, elec-
tronic multimeters, gas meters, timers, calculators,
remote controllers and many other LCD-based indus-
trial and home appliance applications.
