Quick Detail:
8-Bit Microcontroller
Description:
The M68HC11 K-series microcontroller units (MCUs) are
high-performance derivatives of the
MC68HC11F1 and have several additional features. The MC68HC11K0,
MC68HC11K1,
MC68HC11K3, MC68HC11K4 and MC68HC711K4 comprise the series. These
MCUs, with a nonmultiplexed expanded bus, are characterized by high
speed and low power consumption. Their fully static
design allows operation at frequencies from 4 MHz to dc.
This document contains information concerning standard, custom-ROM,
and extended-voltage devices. Standard devices include those with
disabled ROM (MC68HC11K1), disabled EEPROM
(MC68HC11K3), disabled ROM and EEPROM (MC68HC11K0), or EPROM
replacing ROM
(MC68HC711K4). Custom-ROM devices have a ROM array that is
programmed at the factory to customer specifications.
Extended-voltage devices are guaranteed to operate over a much
greater voltage
range (3.0 Vdc to 5.5 Vdc) at lower frequencies than the standard
devices. Refer to the device ordering
information tables for details concerning these differences.
