MC68HC11K Datasheet | Motorola Semiconductor

features . The MC68HC11K0, MC68HC11K1, MC68HC11K3, MC68HC11K4 and MC68HC711K4 prise 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 of Address Space - PROG Mode Allows Use of Standard EPROM Programmer (27C256 Footprint) - Nonmultiplexed Address and Data Buses - Four Programmable Chip Selects with Clock Stretching (Expanded Modes) - Enhanced 16-Bit Timer with Four-Stage Programmable Prescaler - Three Input Capture (IC) Channels - Four Output pare (OC) Channels - One Additional Channel, Selectable as Fourth IC or Fifth OC - 8-Bit Pulse Accumulator - Four 8-Bit or Two 16-Bit Pulse Width Modulation (PWM) Timer Channels - Real-Time Interrupt Circuit - puter Operating Properly (COP) Watchdog - Clock Monitor - Enhanced Asynchronous Nonreturn to Zero (NRZ) Serial munications Interface (SCI) - Enhanced Synchronous Serial Peripheral Interface (SPI) - Eight-Channel 8-Bit Analog-to-Digital (A/D) Converter - Seven...
