MOS INTEGRATED CIRCUIT
µPD78320,78322
16/8-BIT SINGLE-CHIP MICROCONTROLLER
DESCRIPTION
The µPD78322 is a 16-/8-bit single-chip microcontroller that incorporates a high-performance 16-bit CPU. The µPD78322
is one of 78K/III series.
A realtime pulse unit for realtime pulse control required in motor control, an A/D converter, a ROM, and a RAM have been
integrated into one chip.
The µPD78322 incorporates 16K-byte mask ROM and 640-byte RAM.
The µPD78320 is provided as a ROM-less product of the µPD78322. Also, the µPD78P322 is provided as an on-chip
PROM product.
Detailed information about product features and specifications can be found in the following document.
