Order this document by MC68HC11KTS/D Technical Summary 8-Bit Microcontroller M68HC11 K Series 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. 1 Features M68HC11 CPU Power Saving STOP and WAIT Modes 768 Bytes RAM (All Saved During Standby) 24 Kbytes ROM or EPROM 640 Bytes Electrically Erasable Programmable Read Only Memory (EEPROM) Optional Security Feature Protects Memory Contents On-Chip Memory Mapping Logic Allows Expansion to Over 1 Mbyte ...
