Description
The UPD70433GD is a microprocessor that integrates a 16-bit CPU, RAM, serial interface, parallel interface, A/D converter, timers, DMA controller, and interrupt controller in a single chip. It is software-compatible with the µPD70320 and 70330 single-chip microcontrollers and provides a migration path from the V25. The UPD70433GD offers higher-level functions and higher performance, making it particularly suitable for controlling data processing systems associated with mechanical control, including printers and facsimile machines.
