P89C51RB2BP

P89C51RB2BP - 80C51 8-bit Flash microcontroller family 16KB/32KB/64KB ISP/IAP Flash with 512B/512B/1KB RAM

DESCRIPTION

The 89C51RB2/RC2/RD2 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 machine cycle in 6 clock cycles, hence

providing twice the speed of a conventional 80C51. An OTP

configuration bit lets the user select conventional 12 clock timing

if desired.

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% 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 P89C51RB2/RC2/RD2 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.
