Tekmos Inc. a provider of legacy device replacements to extend product life of MCUs, ASICs, standard products and FPGAs, claims the industries first true pin-for-pin, code and timing compatible drop-in replacement for the S87C751 device previously offered by NXP.

The TK87C751 is an integrated MCU combining the Tekmos 8051 Classic CPU core, built in power management, I?C controller, two timers, three parallel ports, 128bytes of internal RAM, plus 65Kbytes of flash program storage, all within the original 28 PLCC package. A version based on the original 24 PDIP is planned for Q2 08.

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.

Tekmos also plans to introduce several derivative products to replace discontinued NXP MCUs, along with the recently discontinued Intel 8031/8051 product offerings and drop in replacements for the Freescale 68HC05 MCU.

Bob Abrams, VP of sales and marketing said the device is engineered to be a compatible drop in replacement. This eliminates any need to modify the PCB or existing software code.

The TK87C751 is available now in a 28 pin PLCC package, and is priced at $7.50 each in quantities of 1,000 units.
