INTRODUCTION
1.1
General
The MC68HC05E0 is a high-performance fully-expandable ROM-less member of the M68HC05
Family of microcomputers. The M68HC05 CPU 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. The MC68HC05E0, with 480 bytes of on-chip RAM and 36 I/O port lines, is available in a
68-pin PLCC package.
1.2
