HT48R50A-1/HT48C50-1
8-Bit I/O Type MCU
Rev. 1.00
1
January 2, 2003
General Description
The device is an 8-bit high performance RISC-like
microcontroller designed for multiple I/O product appli-
cations. The device is particularly suitable for use in
products such as remote controllers, fan/light control-
lers, washing machine controllers, scales, toys and vari-
ous subsystem controllers. A HALT feature is included
to reduce power consumption.
