DESCRIPTION
The
μ
PD78324 is a 16/8-bit single-chip microcontroller that incorporates a high-performance 16-bit CPU. The
μ
PD78324
is one of 78K/III series. The internal capacity is significantly increased compared with the conventional
μ
PD78322.
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
μ
PD78324 incorporates 32K-byte mask ROM and 1024-byte RAM.
The
μ
PD78323 is a ROM-less version of the
μ
PD78324. Also, It is provided the
μ
PD78P324 as an on-chip PROM
product.
Detailed information about product features and specifications can be found in the following document.
