Tekmos, Inc. a leader in legacy device replacements to extend product life of Microcontrollers, ASICs, Standard Products and FPGAs, has introduced the industries first true pin for pin, code and timing compatible drop in replacement for the S87C751 previously offered by NXP. The TK87C751 is an integrated microcontroller combining the Tekmos 8051 Classic CPU core, built in power management, I2C controller, 2 timers, 3 parallel ports, 128 bytes of internal RAM, plus an industry first by including 65K bytes of Flash program storage, all within the original 28 PLCC package. A version based on the original 24 PDIP is planned for the 2nd Quarter of 2008.

The TK87C751 is designed as a pin-for-pin, code and timing compatible drop in replacement for the original S87C751 microcontroller previously offered by NXP. While being compatible with the original design, the TK87C751 offers double the RAM resources and 32 times the program storage. The use of flash for the program storage allows the customer to re-program devices if necessary.

Pricing and Availability
The TK87C751 is available now in a 28 pin PLCC package, and is priced at $7.50 each in quantities of 1000 units.
