DESCRIPTION
The
μ
PD78081(A) and 78082(A) are members of the
μ
PD78083 Subseries of the 78K/0 Series microcontrollers.
These products are produced with a more stringent quality assurance program than that of the
μ
PD78081 and
78082 (standard models) (NEC classifies these products as “special products” by quality grade).
Besides a high-speed, high-performance CPU, these microcontrollers have on-chip ROM, RAM, I/O ports,
8-bit resolution A/D converter, timer, serial interface, interrupt control, and other peripheral hardware.
The
μ
PD78P083(A) including a one-time PROM version which can operate in the same power supply voltage
range as a mask ROM version, and various development tools are available.
The details of the functions are described in the following User’s Manuals. Be sure to read the documents before
starting design.
