P89V660/662/664

8-bit 80C51 5 V low power 16 kB/32 kB/64 kB flash

microcontroller with 512 B/1 kB/2 kB RAM, dual I²C-bus, SPI

Rev. 3.1 — 17 October 2011

Product data sheet

1. General description

The P89V660/662/664 are 80C51 microcontrollers with 16 kB/32 kB/64 kB flash and

512 B/1 kB/2 kB of data RAM. These devices are designed to be drop-in and software

compatible replacements for the P89C660/662/664 devices. Both the In-System

Programming (ISP) and In-Application Programming (IAP) boot codes are upward

compatible.

Additional features of the P89V660/662/664 devices when compared to the

P89C660/662/664 devices are the inclusion of a secondary 100 kHz byte-wide I²C-bus

interface, an SPI interface, four addition I/O pins (Port 4), and the ability to erase code

memory in 128-byte pages.

The IAP capability combined with the 128-byte page size allows for efficient use of the

code memory for non-volatile data storage.

2. Features and benefits

2.1 Principal features

 Dual 100 kHz byte-wide I²C-bus interfaces

 128-byte page erase for efficient use of code memory as non-volatile data storage

 0 MHz to 40 MHz operating frequency in 12x mode, 20 MHz in 6x mode

 16 kB/32 kB/64 kB of on-chip flash user code memory with ISP and IAP

 512 B/1 kB/2 kB RAM

 SPI (Serial Peripheral Interface) and enhanced UART

 PCA (Programmable Counter Array) with PWM and Capture/Compare functions

 Three 16-bit timers/counters

 Four 8-bit I/O ports, one 4-bit I/O port

 WatchDog Timer (WDT)

2.2 Additional features

 30 ms page erase, 150 ms block erase

 Support for 6-clock (default) or 12-clock mode selection via ISP or parallel programmer

 PLCC44 and TQFP44 packages

 Ten interrupt sources with four priority levels

 Second DPTR register

 Low EMI mode (ALE inhibit)

 Power-down mode with external interrupt wake-up
