NXP Semiconductors MCF52110CAF80

Overview

MCF52110CAF80 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded control applications requiring deterministic real-time performance, integrated peripherals, and low-power operation. It features an 80 MHz ColdFire core delivering 76 MIPS (Dhrystone 2.1), 128 KB on-chip flash memory, 16 KB SRAM, three UARTs, two I²C modules, QSPI, eight-channel 12-bit ADC with simultaneous sampling, and four 32-bit DMA-capable timers - deployed in industrial motor control, HVAC systems, and programmable logic controllers.

For engineers reviewing the MCF52110CAF80 datasheet, MCF52110CAF80 pinout, MCF52110CAF80 application, or MCF52110CAF80 equivalent, key selection criteria include its 80 MHz V2 ColdFire core performance, dual watchdog architecture (software + backup), 12-bit ADC timing (1.125 µs min conversion), and support for LQFP-64, QFN-64, MAPBGA-81, and LQFP-100 packages - all critical for legacy industrial design continuity and BOM migration.

Technical Context

The MCF52110CAF80 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 integrates an 8 MHz on-chip relaxation oscillator, PLL with programmable pre-divider, and selectable clock sources (crystal, OCO, or external), enabling flexible low-power mode configuration including sleep and stop states with rapid interrupt wake-up.

Peripheral integration includes a four-channel DMA controller with burst transfer support (up to 16-byte), dual-mode PWM capable of 8×8-bit or 4×16-bit channels with PCM mode, and a dedicated fast ADC with dual sample-and-hold circuits enabling true simultaneous sampling of two analog inputs - essential for closed-loop motor current sensing and phase alignment.

FAQ

What is the maximum operating frequency of the MCF52110CAF80?

The MCF52110CAF80 operates at a maximum core frequency of 80 MHz, enabled by its ColdFire V2 processor core and integrated PLL. This frequency is achievable with proper decoupling, thermal management, and use of the on-chip 8 MHz relaxation oscillator or an external crystal in the 4–25 MHz range. The MCF52110CAF80 delivers 76 MIPS (Dhrystone 2.1) at this speed when executing from internal flash memory.

Does the MCF52110CAF80 support simultaneous sampling on its ADC?

Yes, the MCF52110CAF80 features a fast 12-bit ADC with two independent sample-and-hold circuits, enabling true simultaneous sampling of two analog channels (e.g., AN0 and AN1). This capability is essential for vector control algorithms in motor drives and is confirmed in Section 1.2.10 of the MCF52110 Rev. 1 datasheet. The MCF52110CAF80 achieves a minimum conversion time of 1.125 µs per channel in this mode.

What debug interfaces are available on the MCF52110CAF80?

The MCF52110CAF80 supports Background Debug Mode (BDM) and JTAG IEEE 1149.1 interfaces. However, full real-time trace capability is only available on the 100-pin LQFP variant (e.g., MCF52110CAG80). The MCF52110CAF80 - in its 64-pin LQFP package - provides the dedicated debug serial channel (DSI/DSO/DSCLK) and ALLPST signal, enabling in-circuit debugging and basic breakpoint functionality without requiring external emulators.

Can the MCF52110CAF80 be used in safety-critical applications?

Yes, the MCF52110CAF80 includes dual independent watchdog timers (32-bit software WDT and 16-bit backup WDT), low-voltage detection with interrupt/reset capability, and a robust reset controller tracking seven distinct reset sources. These features support functional safety requirements per IEC 61508 SIL-2 when implemented with appropriate software diagnostics. The MCF52110CAF80 has been deployed in certified medical and industrial control systems where such redundancy is mandated.

What package options are available for the MCF52110CAF80?

The MCF52110CAF80 is specifically designated for the 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. While the broader MCF52110 family also includes QFN-64, MAPBGA-81, and LQFP-100 variants, the "CAF80" suffix unambiguously identifies the LQFP-64 version. Mechanical drawings and land patterns are provided in Section 3.1 of the MCF52110 Rev. 1 datasheet.
