General Description
The HT48R06A-1/HT48C06 are 8-bit high perfor
mance, RISC architecture microcontroller devices spe
cifically designed for cost-effective multiple I/O control
product applications. The mask version HT48C06 is
fully pin and functionally compatible with the OTP ver
sion HT48R06A-1 device.
