概述
Description
The MC68HC11E1CFNE3R is an 8-bit microcontroller from Motorola's HC11 family, featuring:
- 8-bit CPU with up to 2 MHz clock speed
- 512 bytes RAM, 12 KB ROM, and 512 bytes EEPROM
- On-chip peripherals: Timers, PWM, serial interfaces (SCI, SPI), and an 8-channel 8-bit ADC
- Operating voltage: 4.5V–5.5V
- 40-pin DIP package
Designed for embedded control applications, it offers robust I/O capabilities and low-power modes. The CFNE3R suffix indicates industrial temperature range (-40°C to +85°C) and lead-free packaging.
Common uses include automotive systems, industrial automation, and consumer electronics. Its legacy architecture makes it suitable for simple, cost-sensitive designs.
