TK80C51FA Microcontroller

Description

The TK80C51FA combines most of the 8051 architecture peripherals into a single chip. It may be used as a pin-for-pin replacement for earlier generations of the 8051 such as the 80C31BH, the 80C32-1, the 80C32X2, and the 80C51FA. This is a new design, created using the Tekmos configurable microprocessor technology, and implemented in our 0.35u CMOS process. The use of the original instruction timing insures that the original code will continue to perform correctly while running in the Tekmos design.

The performance advantages resulting from the 0.35u process allow the Tekmos part to replace all of the earlier version’s speed grades. The use of a current process also insures the long term availability of this part.

The TK80C32 is available in the 40 pin PDIP, the 44 pin PLCC, and the 44 pin QFP packages.

For further information, please check the TK80C51FA data sheet or contact the factory.
