Description
General Description
The HT49R50A-1/HT49C50-1/HT49C50L are 8-bit,
high performance, RISC architecture microcontroller
devices specifically designed for a wide range of LCD
applications.
The mask version HT49C50-1 and HT49C50L are fully pin and functionally compatible with
the OTP version HT49R50A-1 device.
The HT49C50L is a low voltage version, with the ability to operate at a
minimum power supply of 1.2V, making it suitable for
single cell battery applications.
The advantages of low power consumption, I/O flexibility, programmable frequency divider, timer functions,
oscillator options, HALT 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.
