MC68HC711E20CFN3

Motorola's MC68HC711E20CFN3 microcontroller is a standout member of the HC11 family, offering a robust set of features for embedded system design. With its 8-bit architecture and a maximum CPU frequency of 3.68 MHz, this MCU is well-suited for applications in automotive, industrial control, and consumer electronics. Its 512 bytes of RAM, 16KB of on-chip EPROM, and 512 bytes of EEPROM provide ample memory for storage and data processing, while the 16-bit timer system, UART module, and 38 general-purpose I/O pins offer flexible interfacing options. Housed in a 52-pin PLCC package, the MC68HC711E20CFN3 operates within a voltage range of 4.5V to 5.5V, making it compatible with a variety of power sources
