DESCRIPTION
The
μ
PD78070AY is a limited-function product from which the on-chip ROM of the
μ
PD78078Y Subseries has been
removed. Through interchangeable external ROM, program maintenance can be performed easily. Besides a high-
speed, high-performance CPU, this microcontroller has on-chip RAM, I/O ports, 8-bit resolution A/D converter,
8-bit resolution D/A converter, timer, serial interface, real-time output port, interrupt control, and various other
peripheral hardware.
Detailed information about product features and specifications can be found in the following documents.
