Download the P89C664 datasheet PDF.
This datasheet also covers the P89C660 variant, as both devices belong to the same 8-bit 80c51 5v low power 16 kb/32 kb/64 kb flash microcontroller family and are provided as variant models within a single manufacturer datasheet.
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.

kB RAM, dual I2C-bus, SPI Rev. 3.1 — 17 October 2011 Product data sheet 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
