Technical Summary
8-Bit Microcontroller
1 Introduction
The MC68HC11KA4 family of microcontrollers are enhanced derivatives of the MC68HC11F1 and, as
shown in the block diagram, include many additional features. The family includes the MC68HC11KA0,
MC68HC11KA1, MC68HC11KA3, MC68HC11KA4, MC68HC711KA4, MC68HC11KA2, and the
MC68HC711KA2. These MCUs, with a non-multiplexed expanded bus, are characterized by high
speed and low power consumption. The fully static design allows operation at frequencies from 4 MHz
to dc.
This technical summary contains information concerning standard, custom-ROM, and extended-volt-
age devices. Standard devices are those with disabled ROM (MC68HC11KA1), disabled EEPROM
(MC68HC11KA0), and EPROM replacing ROM (MC68HC711KA4). The MC68HC11KA2 and
MC68HC711KA2 contain 32 Kbytes of ROM/EPROM instead of 24 Kbytes. 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 ordering information on the following pages.
In this summary, ROM/EPROM refers to ROM for ROM-based devices and refers to EPROM for
EPROM-based devices.
