The Freescale Semiconductor MC68HC11K1CFUE3 is an 8-bit microcontroller from the HC11 series, designed for embedded systems. This device features a ROMless architecture, requiring external memory for program storage, providing flexibility for developers. It operates at a clock speed of 4MHz and includes 768 Bytes of internal RAM for data handling.
With 37 I/O pins, the MC68HC11K1CFUE3 offers ample connectivity for interfacing with external components. It is equipped with essential peripherals such as Power-On Reset (POR), Pulse Width Modulation (PWM), and a Watchdog Timer (WDT) to enhance system reliability and control. The integrated A/D converter provides 8-bit resolution across 8 channels, enabling analog signal acquisition.
This microcontroller operates within a supply voltage range of 4.5V to 5.5V and functions reliably in industrial temperature conditions, from -40°C to 85°C. It is packaged in an 80-pin QFP (Quad Flat Package) with surface mount technology, making it suitable for compact PCB designs. The internal oscillator simplifies system design by eliminating the need for an external clock source.
The MC68HC11K1CFUE3 supports standard serial communication interfaces like SCI and SPI, facilitating data exchange with other devices. Its ROMless design makes it ideal for applications where program code needs to be dynamically loaded or updated, or for systems that utilize external memory for program execution. This part is compliant with RoHS3 standards.
