P89V660FA 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 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)
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
• Idle mode
