DESCRIPTION
The P89C668 device contains a non-volatile 64 kbytes Flash
program memory that is both parallel programmable and serial
In-System Programmable. In-System Programming allows devices
to alter their own program memory, in the actual end product, under
software control. This opens up a range of applications that can
include the ability to field update the application firmware.
A default serial loader (boot loader) program in ROM allows serial
In-System programming of the Flash memory without the need for a
loader in the Flash code. User programs may erase and reprogram
the Flash memory at will through the use of standard routines
contained in ROM.
This device is a Single-Chip 8-Bit Microcontroller manufactured in
advanced CMOS process and is a derivative of the 80C51
microcontroller family. The device has the same instruction set as
the 80C51.
The device also has four 8-bit I/O ports, three 16-bit timer/event
counters, a multi-source, four-priority-level, nested interrupt structure,
an enhanced UART and on-chip oscillator and timing circuits.
The added features of the P89C668 makes it a powerful microcontroller
for applications that require pulse width modulation, high-speed I/O and
up/down counting capabilities such as motor control.
