P89V664FA Microcontrollers: Datasheet, Pinout, Circuit

Product Overview

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.

 

This blog will introduce P89V664FA systematically from its features, pinout to its specifications, applications, also including P89V664FA datasheet and so much more.
