MC68711E20CFNE2 8-bit microcontroller 2MHz 20KB EPROM
The MC68711E20CFNE2 is an 8-bit microcontroller unit (MCU) from NXP Semiconductors (formerly Motorola), designed for embedded control applications requiring robust performance and versatile peripheral integration. Based on the Motorola 6800 CPU architecture, it operates at a 2 MHz clock frequency and features 20 KB of on-chip EPROM (Erasable Programmable Read-Only Memory) and 512 bytes of RAM, providing sufficient memory for real-time control tasks in industrial, automotive, and consumer electronics. The MCU includes a 16-bit timer system with input capture/output compare functionality, a serial communication interface (SCI), and a serial peripheral interface (SPI), enabling efficient communication with external devices. Additionally, it integrates an 8-channel, 8-bit analog-to-digital converter (ADC), making it suitable for sensor-based applications requiring analog signal processing.
The MC68711E20CFNE2 is housed in a 52-pin PLCC (Plastic Leaded Chip Carrier) package, offering a compact footprint for space-constrained designs. It operates within a 4.5V to 5.5V voltage range, ensuring compatibility with standard 5V logic systems. The MCU supports low-power standby and stop modes, enhancing energy efficiency in battery-operated applications. Its extended temperature range (-40°C to +85°C) ensures reliable performance in harsh environments, making it ideal for automotive and industrial control systems. The device also features on-chip debugging support, simplifying firmware development and troubleshooting.
For applications requiring modern alternatives with enhanced performance, comparable microcontrollers include the MC68HC11A8 (8-bit, 8 MHz, 8 KB ROM), MC68HC12B32 (16-bit, 25 MHz, 32 KB Flash), and MC9S12C128 (16-bit, 25 MHz, 128 KB Flash). These alternatives provide varying levels of processing power, memory capacity, and peripheral integration to meet different embedded system requirements.
