UPD75048 Overview
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)
- Built-in 8-bit resolution A/D converter (successive approximation): 8 channels
- Capable of operating at low voltage: VDD = 2.7 to 6.0 V
- Reference voltage can be arbitrarily specified between AVREF+ and AVREF
- Built-in multi-function timer which can provide the following functions
- 8-bit timer
- PWM output
- 16-bit free running timer
- 16-bit integration type A/D converter counter
- I/O ports: 48 pins
