![]() The MC68HC11 is available in two packages.One serial peripheral interface, with a speed up to 1M (baud rate).Eight channel 8-bit Analog to Digital Convertor.256 Bytes of RAM, 512 Bytes of In-System Programmable EEPROM.The HCMOS MC68HC11 is an advanced 8-bit MCU with numerous on-chip peripheral capabilities.Test mode : used by Motorola to test the chip is operation Bootstrap mode: used to load programs into RAM. Expanded mode :allows for use of external memory. The 6811 can operate in one of the four modes: Single-chip mode: uses internal memory for program & data. The 68HC11 chip has built-in EEPROM/ROM, RAM, digital I/O, timers, A/D converter, PWM (Pulse width modulator) generator, and synchronous and asynchronous communications channels.It is a CISC microcontroller, optimized for low power consumption and high-performance operation. ![]() Now it is produced by Freescale Semiconductors. Motorola Inc ,one of the pioneers in microcontroller manufacturing has introduced this 8-bit microcontroller M68HC11 in the year 1985 and it is descended from the Motorola 6800 microprocessor.INTRODUCTION TO MC 68HC11 MICROCONTROLLER
