Product Summary
The MC68HC05E0FN is a high-performance fully-expandable ROM-less microcomputer. The MC68HC05E0FN core has been enhanced with two powerful, independently controlled timer subsystems, and a serial interface (SI) which can operate in either SPI (Serial Peripheral Interface) or I2C-bus compatible mode. An external 16-bit address/8-bit data expansion bus and chip-select logic are provided to allow access to external ROM, RAM and I/O. TheMC68HC05E0FN, with 480 bytes of on-chip RAM and 36 I/O port lines, is available in a 68-pin PLCC package.
