General Description
1.1 Introduction
This document contains a detailed description of the M68HC11 E series of 8-bit microcontroller units
(MCUs). These MCUs all combine the M68HC11 central processor unit (CPU) with high-performance,
on-chip peripherals.
The E series is comprised of many devices with various configurations of:
With the exception of a few minor differences, the operation of all E-series MCUs is identical. A fully static
design and high-density complementary metal-oxide semiconductor (HCMOS) fabrication process allow
the E-series devices to operate at frequencies from 3 MHz to dc with very low power consumption.
1.2 Features
Features of the E-series devices include:
