General Description

The HT49RA1/HT49CA1 is a Remote Type 8-bit MCU

8-bit high performance RISC architecture

microcontroller. With its internal carrier generator and

LCD Driver functions the device is is especially suitable

for multiple I/O remote control product applications. The

usual Holtek MCU features such as power down and

wake-up functions, oscillator options, etc. combine to

ensure user applications require a minimum of external

components.

The benefits of low power consumption, high perfor-

mance, I/O flexibility and low-cost, provide these de-

vices with the versatility to suit a wide range of

application possibilities such as industrial control, con-

sumer products and particularly suitable for use in prod-

ucts such as infrared LCD remote controllers and

various, subsystem controllers, etc.
