Although compatible with the original NXP S87C751 design, the TK87C751 offers double the RAM resources and 32x the program storage.
The TK89C668 also contains hardware support for the TWI interface, a watchdog timer, security features, and all extended 8051 peripherals.
It provides a choice of a 6x or 12x clock with classic timing, and is packaged in a 44-pin PLCC package.

The Tekmos TK89C668 offers customers the security of a stable product supply now and in the future.
Tekmos also plans to introduce several derivative products to replace older NXP microcontrollers, along with the recently discontinued Intel 8031/8051 product offerings and drop in replacements for the Freescale 68HC05 microcontroller.
According to Bob Abrams, Vice President of Sales and Marketing: "The device is engineered to be a compatible drop in replacement".
"This eliminates any need to modify the printed circuit board or existing software code".
The TK89C668 is available now in a 44-pin PLCC package, and is priced at US $7.50 each in quantities of 1000 units.
