P89V664FA PHILIPS Controller

P89V664FA Overview

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.
Principal features
■Dual 100kHz byte-wide 12C-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
■16kB/32kB/64 kB of on-chip flash user code memory with ISP and IAP
■512 B/1kB/2kB 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/O port
■WatchDog Timer（WDT）
Additional features
■30 ms page erase，150 ms block erase
■Support for 12-clock（default）or 6-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
