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
· Watchdog Timer
· Buzzer output
· On-chip crystal, RC and 32768Hz crystal oscillator
· Power-down and wake-up feature reduce power con-
sumption
· 2-level subroutine nesting
· Bit manipulation instruction
· 14-bit table read instruction
· Up to 0.5ms instruction cycle with 8MHz system clock
· 63 powerful instructions
· All instructions executed in 1 or 2 machine cycles
· Low voltage reset/detector
· 44-pin QFP/LQFP package

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.
