NXP Semiconductors MCF52100CVM66

Overview

MCF52100CVM66 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control applications requiring deterministic real-time response, integrated analog acquisition, and multi-protocol connectivity. It operates at 66 MHz, integrates 64 KB flash and 16 KB SRAM, features an 8-channel 12-bit ADC with simultaneous sampling, three UARTs, two I²C modules, QSPI, four DMA-capable 32-bit timers, and dual watchdogs - deployed in industrial motor control, HVAC controllers, and programmable logic modules.

For engineers reviewing the MCF52100CVM66 datasheet, MCF52100CVM66 pinout, MCF52100CVM66 application, or MCF52100CVM66 equivalent, key selection criteria include its 66 MHz V2 ColdFire core performance (57 MIPS Dhrystone), LQFP-64 package compatibility, 12-bit ADC timing (1.125 µs min conversion), UART/I²C coexistence, and flash memory programming via EzPort interface.

Technical Context

The MCF52100CVM66 implements the ColdFire ISA_A+ instruction set with hardware MAC unit and 32-bit accumulator supporting 16×16→32 and 32×32→32 operations. Its clock system combines an on-chip 8 MHz relaxation oscillator, external crystal support, and PLL with programmable pre-divider and low-power dividers (2ⁿ, n=0–15).

Peripheral integration includes a four-channel DMA controller with burst transfers and channel linking, a dedicated QSPI master with up to 16 queued transfers, and dual PWM timer configurations: eight 8-bit channels or four concatenated 16-bit channels with PCM mode, center/left-aligned outputs, and emergency shutdown.

FAQ

What is the maximum operating frequency of the MCF52100CVM66?

The MCF52100CVM66 operates at a maximum system clock frequency of 66 MHz. This is achieved using the on-chip PLL locked to either an external crystal or the internal 8 MHz relaxation oscillator. At this speed, the ColdFire V2 core delivers 57 MIPS (Dhrystone 2.1), enabling hard real-time response in motor control and industrial PLC applications. The MCF52100CVM66 does not support the 80 MHz configuration available in the MCF52110 variant.

Does the MCF52100CVM66 support in-system flash programming?

Yes, the MCF52100CVM66 supports in-system flash programming via the EzPort interface - a synchronous serial interface compatible with standard SPI flash protocols. This allows external hosts to read, erase, and program the internal 64 KB flash memory without requiring JTAG or BDM debug tools. EzPort is commonly used for field firmware updates and manufacturing provisioning.

How many UART interfaces does the MCF52100CVM66 include?

The MCF52100CVM66 includes two independent full-duplex UART modules (UART0 and UART1). Unlike the MCF52110, it does not integrate a third UART; that functionality is omitted in the MCF52100 variant per Table 1 in the Freescale MCF52110 datasheet Rev. 1. Both UARTs support DMA, FIFO buffering, and modem control signals (RTS/CTS) where pin-muxed.

What ADC capabilities does the MCF52100CVM66 provide?

The MCF52100CVM66 integrates an 8-channel, 12-bit fast analog-to-digital converter with a minimum conversion time of 1.125 µs. It supports simultaneous sampling on two channels (e.g., AN0/AN1), essential for vector-controlled motor drives. Unused analog inputs may be repurposed as digital I/O. Conversion results trigger interrupts or DMA requests, and threshold-based alarms (low/high limit, zero crossing) are fully programmable.

Is the MCF52100CVM66 pin-compatible with other ColdFire family members?

No, the MCF52100CVM66 is not pin-compatible with MCF52110 variants despite sharing the LQFP-64 package. Differences in peripheral mapping - especially the absence of UART2 and reduced peripheral clock gating registers - require board-level redesign. Pin compatibility is only guaranteed within identical part numbers and revision codes; cross-family substitution mandates full schematic and layout validation.
