1 / 89 page 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 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 6-clock (default) or 12-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 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. 03 — 10 November 2008 Product data sheet |
