Sony CXP828P60 Datasheet

Description

The CXP828P60 is a CMOS 8-bit single chip
microcomputer integrating on a single chip an A/D
converter, serial interface, timer/counter, time base
timer, capture timer/counter, fluorescent display panel
controller/driver, remote control reception circuit, and
PWM output circuit besides the basic configurations
of 8-bit CPU, PROM, RAM, and I/O port.

The CXP828P60 also provides sleep/stop function
that enables lower power consumption.

CXP828P60 is the PROM-incorporated version of
the CXP82860 with bult-in mask ROM. This provides
the additional feature of being able to write directly
into the program. Thus, it is most suitable for
evaluation use during system development and for
small-quantity production.
