NXP Semiconductors MCF52110CVM66

Overview

MCF52110CVM66 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control applications requiring integrated peripherals, deterministic real-time response, and low-power operation. It features an 80 MHz CPU core delivering 76 MIPS (Dhrystone 2.1), 128 KB on-chip flash memory, 16 KB SRAM, three UARTs, two I²C interfaces, QSPI, eight-channel 12-bit ADC with simultaneous sampling, and four 32-bit DMA-capable timers.

For engineers reviewing the MCF52110CVM66 datasheet, MCF52110CVM66 pinout, MCF52110CVM66 application, or MCF52110CVM66 equivalent, key selection criteria include its LQFP-64 package compatibility, 66 MHz clock rating (confirmed in Table 1), ColdFire V2 ISA_A+ instruction set support, integrated PLL with 8 MHz relaxation oscillator, and dual watchdog architecture with independent backup timer.

Technical Context

The MCF52110CVM66 implements the ColdFire Version 2 core with a dual-pipeline architecture (IFP/OEP), MAC unit for 16×16/32×32 integer and fractional operations, and hardware divider. Its interrupt controller supports 57 sources with programmable priority and vectoring, and debug is enabled via BDM and JTAG (reduced interface on 64-pin packages).

On-chip timing resources include four 32-bit DTIMs with 12.5 ns resolution at 80 MHz, four 16-bit GPT channels supporting input capture/output compare/PWM/pulse accumulation, and two 16-bit PITs. The ADC uses dual sample-and-hold circuits enabling true simultaneous sampling of two channels - critical for motor phase current measurement.

FAQ

What is the maximum operating frequency of the MCF52110CVM66?

The MCF52110CVM66 is factory-specified and tested for reliable operation at up to 66 MHz, as explicitly stated in Table 1 "MCF52110 Family Configurations" of the Rev. 1 datasheet. While the underlying ColdFire V2 core supports 80 MHz, this specific variant (CVM66) is binned and qualified for 66 MHz - exceeding this frequency violates electrical specifications and voids warranty.

Does the MCF52110CVM66 support simultaneous sampling on its ADC?

Yes, the MCF52110CVM66 integrates two independent sample-and-hold (S/H) circuits feeding separate 12-bit ADCs, enabling true simultaneous sampling of two analog channels. This capability is documented in Section 1.2.10 and is essential for accurate phase current measurement in motor control applications.

What debug interfaces are available on the MCF52110CVM66 in its LQFP-64 package?

The MCF52110CVM66 in LQFP-64 provides Background Debug Mode (BDM) and a reduced JTAG interface per Section 1.2.3 - including dedicated debug serial communication (DSI/DSO/DSCLK), ALLPST signal, and breakpoint registers. Full real-time trace is reserved for 100-pin packages; however, BDM enables full in-circuit debugging at full speed.

Can the MCF52110CVM66 operate from an internal clock source without an external crystal?

Yes, the MCF52110CVM66 includes an 8 MHz on-chip trimmed relaxation oscillator (OCO) that can serve as the primary clock source. The clock module supports direct OCO use or PLL multiplication, allowing crystal-free operation for cost-sensitive or space-constrained designs - though RTC accuracy requires a 32.768 kHz crystal.

How many UART interfaces does the MCF52110CVM66 support, and are all available on the LQFP-64 package?

The MCF52110CVM66 integrates three UART modules. On the LQFP-64 package, UART0 and UART1 are fully available on dedicated pins, while UART2 is multiplexed with general-purpose I/O pins (Section 1.2.7). All three UARTs support DMA, FIFO, and modem handshaking - UART2 functionality requires careful pin assignment during PCB layout.
