DESCRIPTION
The P89C660/662/664/668 device contains a non-volatile
16KB/32KB/64KB Flash program memory that is both parallel
programmable and serial In-System and In-Application
Programmable. In-System Programming (ISP) allows the user to
download new code while the microcontroller sits in the application.
In-Application Programming (IAP) means that the microcontroller
fetches new program code and reprograms itself while in the
system. This allows for remote programming over a modem link.
A default serial loader (boot loader) program in ROM allows serial
In-System Programming of the Flash memory via the UART without
the need for a loader in the Flash code. For In-Application
Programming, the user program erases and reprograms the Flash
memory by use of standard routines contained in ROM.
This device executes one instruction in 6 clock cycles, hence
providing twice the speed of a conventional 80C51. An OTP
configuration bit gives the user the option to select conventional
12-clock timing.
This device is a Single-Chip 8-Bit Microcontroller manufactured in
advanced CMOS process and is a derivative of the 80C51
microcontroller family. The instruction set is 100% executing and
timing compatible with the 80C51 instruction set.
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 P89C660/662/664/668 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.
