TK68HC705B 

 

General Description  

The TK68HC705B is a derivative of the HC05 microcontroller architecture. With a rich set of RAM, ROM, and EEPROM memory and a full set of peripherals, the TK68HC705B is well suited to a variety of controller tasks. These parts have been designed to be drop-in replacements for the NXP MC68HC705B16 or MC68HC705B32, with identical code execution, pin compatibility, and equivalent timing.
