MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC68HC11KA4TS/D M68HC11 KA Series 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-voltage 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. 1.1 Features M68HC11 Central Processing Unit (CPU) Power Saving STOP and WAIT Modes 768 Bytes RAM in MC68HC11KA4, 1024 Bytes RAM in MC68...
