MCHC11F1CFNE2 – FREESCALE

The MCHC11F1CFNE2 is a Freescale (formerly Motorola) 8-bit microcontroller belonging to the 68HC11 family. Fabricated using a CMOS process, this device features an enhanced HC11 core, offering improved performance over earlier HC11 variants. The ‘F1’ designation indicates a specific memory configuration, typically including 1KB of on-chip EEPROM, 256 bytes of RAM, and no ROM. The CFNE2 suffix denotes a specific package type, likely a PDIP (Plastic Dual In-line Package) suitable for through-hole mounting. The device incorporates a variety of peripherals, including a serial communication interface (SCI), a synchronous serial peripheral interface (SPI), an 8-channel analog-to-digital converter (ADC), and multiple timer functions, including input capture and output compare capabilities. Its instruction set is upward compatible with the original 6800 instruction set, facilitating code migration. The MCHC11F1CFNE2 operates from a 5V power supply.
