MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC68HC11A8TS/D MC68HC11A8 MC68HC11A1 MC68HC11A0 Technical Summary 8-Bit Microcontrollers 1 Introduction The MC68HC11A8, MC68HC11A1, and MC68HC11A0 high-performance microcontroller units (MCUs) are based on the M68HC11 Family. These high speed, low power consumption chips have multiplexed buses and a fully static design. The chips can operate at frequencies from 3 MHz to dc. The three MCUs are created from the same masks; the only differences are the value stored in the CONFIG register, and whether or not the ROM or EEPROM is tested and guaranteed. For detailed information about specific characteristics of these MCUs, refer to the M68HC11 Reference Manual (M68HC11RM/AD). 1.1 Features M68HC11 CPU Power Saving STOP and WAIT Modes 8 Kbytes ROM 512 Bytes of On-Chip EEPROM 256 Bytes of On-Chip RAM (All Saved During Standby) 16-Bit Timer System — 3 Input Capture Channels — 5 Output Compare Channels 8-Bit Pulse Accumulator Real-Time Interrupt Circuit Computer Operating Properly (COP) Watchdog System Synchronous Serial Peripheral Interface (SPI) Asynchronous Nonreturn to Zero (NRZ) Serial Communications Interface (SCI) 8-Channel, 8-Bit Analog-to-Digital (A/D) Converter 38 General-Purpose Input/Output (I/O) Pins — 15 Bidirectional I/O Pins — 11 Input-Only Pins and 12 Output-Only Pins (Eight Output-Only Pins in 48-Pin Package) Available in 48-Pin Dual In-Line Package (DIP) or 52-Pin Plastic Lead...
