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 flexibil- ity, 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 possi- bilities such as measuring scales, electronic multi- meters, gas meters, timers, calculators, remote controllers and many other LCD-based industrial and home appliance applications.
