TK68HC811E2 175ºC Microcontroller

General Description

The TK68HC811E2 is a member of the TK68HC11E family of MCUs. The full set of specifications can be found in the datasheet TK68HC11E. The operation of the entire family is largely the same except for the various configurations of RAM, ROM, or EPROM.

The Tekmos TK68HC811E2 is available in a 175ºC version.

The TK68HC811E2 is a fully static design using high-density complementary metal-oxide semiconductor (HCMOS) fabrication process that allows it to operate at frequencies from 2 MHz to dc, with very low power consumption.

The device is available in 48 pin DIP packages with the following pinout:
