MCU drops in to upgrade memory
The TK89C668 is designed as a pin-for-pin, code and timing compatible drop in replacement for the original P89C668 microcontroller offered by NXP.
A version based on the original 24-PDIP is planned for Q2 2008.
Although compatible with the original NXP S87C751 design, the TK87C751 offers double the RAM resources and 32x the program storage.
The use of Flash for the program storage allows the customer to reprogram devices if necessary.
Tekmos also plans to introduce several derivative products to replace discontinued NXP microcontrollers, along with the recently discontinued Intel 8031/8051 product offerings and drop in replacements for the Freescale 68HC05 microcontroller.
Bob Abrams, Vice President of Sales and Marketing says 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 TK87C751 is available now in a 28-pin PLCC package, and is priced at US $7.50 each in quantities of 1000 units.
