Introduction

The M68HC11K Family of high-performance microcontroller units (MCUs) offers a non-multiplexed expanded bus, high speed and low power consumption. The fully static design allows operation at

frequencies from dc to 4 MHz. This manual contains information concerning standard and

custom-ROM (read-only memory) devices. Standard devices include those replacing the ROM with:

? Disabled ROM

? Disabled EEPROM (electrically erasable, programmable read-only memory)

? EPROM (erasable, programmable read-only memory)

? OTPROM (one-time progammable read-only memory)

Custom-ROM devices have a ROM array that is programmed at the factory to customer specifications.
