MCF51QE32CLH

The Freescale Semiconductor MCF51QE32CLH is a 32-bit microcontroller featuring the ColdFire V1 Central Processor Unit (CPU). It can operate at speeds up to 50.33 MHz when powered above 2.4V, providing significant processing power for embedded applications. The microcontroller offers 0.94 Dhrystone 2.1 MIPS per MHz performance when running from internal RAM.

On-chip memory includes flash for program storage and RAM for data. Security circuitry is integrated to prevent unauthorized access to memory contents. The device supports up to 30 peripheral interrupt requests and seven software interrupts, facilitating efficient interrupt handling.

Key peripherals include a 24-channel, 12-bit Analog-to-Digital Converter (ADC) with a 2.5 µs conversion time and an integrated temperature sensor. Two analog comparators and two Serial Communication Interface (SCI) modules are also provided, enhancing its connectivity and measurement capabilities. The microcontroller supports low-power modes with a typical wake-up time of 6 µs from stop modes.

Clock source options include an external oscillator (XOSC) supporting crystal or ceramic resonators in various frequency ranges, and an internal clock source (ICS) with an FLL for precise frequency control from 2 to 50.33 MHz. System protection features include a watchdog timer and low-voltage detection.
