TECHNICAL DATA

This document contains information on a new product. Speciﬁcations and information herein are subject to change without notice.

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.

• Eight-Channel 8-Bit Analog-to-Digital (A/D) Converter (Four Channels on 64-Pin Version)

• Seven Bidirectional Input/Output (I/O) Ports (43 Pins)

• One Fixed Input-Only Port (8 Pins, 4 Pins on 64-Pin Version)

• Available in 68-Pin Plastic Leaded Chip Carrier (Custom ROM/OTPROM), 68-Pin Windowed Ce-

ramic Leaded Chip Carrier (EPROM), or 64-Pin Quad Flat Pack (Custom ROM/OTPROM)

— Three Input Capture (IC) Channels

— Four Output Compare (OC) Channels

— One Additional Channel, Selectable as Fourth IC or Fifth OC
