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. 01 — 2 May 2007
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 P89V660/662/664 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
P89V660/662/664 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
2.1 Principal features
I Dual 100 kHz byte-wide I2C-bus interfaces
I 128-byte page erase for efficient use of code memory as non-volatile data storage
I 0 MHz to 40 MHz operating frequency in 12x mode, 20 MHz in 6x mode
I 16 kB/32 kB/64 kB of on-chip flash user code memory with ISP and IAP
I 512 B/1 kB/2 kB RAM
I SPI (Serial Peripheral Interface) and enhanced UART
I PCA (Programmable Counter Array) with PWM and Capture/Compare functions
I Three 16-bit timers/counters
I Four 8-bit I/O ports, one 4-bit I/O port
I WatchDog Timer (WDT)
2.2 Additional features
I 30 ms page erase, 150 ms block erase
I Support for 12-clock (default) or 6-clock mode selection via ISP or parallel programmer
I PLCC44 and TQFP44 packages
I Ten interrupt sources with four priority levels
I Second DPTR register
I Low EMI mode (ALE inhibit)
I Power-down mode with external interrupt wake-up
