Description
The CXP861P16 is a highly integrated CMOS 8-bit
single-chip microcomputer which is mainly composed
of an 8-bit CPU, PROM, RAM and I/O ports. This
microcomputer features many other high-
performance circuits in a single-chip CMOS design,
including an A/D converter, clock synchronized serial
interface, UART, stepping motor controller, PWM
generator, 16-bit timer/counter, and watchdog timer.
Also, the CXP861P16 provides the power-on reset
function as well as the sleep/stop function which
enables to lower power consumption.
This IC is the PROM-incorporated version of the
CXP86116 with built-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.
