UPD75048 Description
The µPD75408 is a 4-bit single-chip microputer whose data processing capability is parative to that of an 8-bit microputer. The µPD75048 employs a CPU whose minimum instruction execution time is 0.95 µs, and contains the EEPROM, A/D converter, multi-function timer, and high performance hardware to provide high cost to performance ratio. Detailed functions are described in the following user's manual.
UPD75048 Key Features
- Built-in EEPROM: 1024 x 4 bits (data memory area)
