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.
