68HC11 datasheet



A microcontroller is a small, low-cost computer-on-a-chip that is designed to control devices. It typically includes a central processing unit (CPU), memory, input/output interfaces, and other peripherals all on a single chip. Microcontrollers are used in a wide range of applications, including consumer electronics, automotive systems, industrial control systems, and medical devices. They are known for their efficiency, low power consumption, and ability to operate in real-time. They can be programmed in a variety of programming languages, including C, Assembly, and BASIC, and can be used to execute complex tasks in response to input from sensors or other devices.

This document contains a detailed description of the M68HC11 E series of 8-bit microcontroller units(MCUs). These MCUs all combine the M68HC11 central processor unit (CPU) with high-performance, on-chip peripherals.

The high-density complementary metal-oxide semiconductor (HCMOS) 68HC11 is an advanced 8-bit MCU with highly sophisticated, on-chip peripheral capabilities. New design techniques were used to achieve a nominal bus speed of 2 MHz. In addition, the fully static design allows operation at frequencies down to dc, further reducing power consumption.


The E series is comprised of many devices with various configurations of:

1. Random-access memory (RAM)
2. Read-only memory (ROM)
3. Erasable programmable read-only memory (EPROM)
4. Electrically erasable programmable read-only memory (EEPROM)
5. Several low-voltage devices are also available.
