NXP Semiconductors MCF5216CVF66J

Overview

MCF5216CVF66J from NXP (formerly Freescale) is a 32-bit ColdFire V2 core microcontroller featuring 66 MHz operation, 128 KB on-chip Flash memory, and 16 KB SRAM. It integrates EMAC, cache, FlexCAN, QSPI, UARTs, I²C, QADC, and programmable timers. Designed for industrial control and networked embedded systems requiring deterministic real-time response and low-power operation.

For engineers reviewing the MCF5216CVF66J datasheet, MCF5216CVF66J pinout, MCF5216CVF66J application, or MCF5216CVF66J equivalent, key selection considerations include its 66 MHz ColdFire V2 core performance, integrated FlexCAN 2.0B interface, 128 KB flash with security protection, 16 KB SRAM, and support for external SDRAM via EIM - all in a 144-pin LQFP package.

Technical Context

The MCF5216CVF66J implements the ColdFire V2 microarchitecture with a 5-stage pipeline, 4 KB instruction/data unified cache, and enhanced multiply-accumulate (EMAC) unit supporting fractional arithmetic. It executes ISA_A+ instructions with cycle-accurate timing defined per operation type (e.g., MOVE, branch, EMAC).

Its system-level architecture includes a System Control Module (SCM) managing bus arbitration and privilege access, Clock Module with PLL supporting 1:1 and normal modes, and Power Management enabling Run, Wait, Doze, and Stop modes. Peripheral behavior-including FlexCAN, QADC, and UART-is explicitly defined across each low-power state.

FAQ

What is the maximum operating frequency of the MCF5216CVF66J?

The MCF5216CVF66J operates at a maximum frequency of 66 MHz, achieved using its on-chip Phase-Locked Loop (PLL) driven by an external 4–33 MHz clock source. This frequency governs core instruction execution, cache access, and synchronous peripheral timing - all verified under specified voltage (1.5 V core, 3.3 V I/O) and temperature conditions per Freescale's electrical characteristics.

Does the MCF5216CVF66J include on-chip Flash memory and what security features does it support?

Yes, the MCF5216CVF66J integrates 128 KB of on-chip ColdFire Flash Module (CFM) with configurable protection zones, security lock bits, and back-door access keys. The CFMSEC register enables permanent disabling of debug access and flash programming, while CFMPROT allows granular sector write/erase protection - essential for firmware IP protection in deployed devices.

Which communication interfaces are integrated into the MCF5216CVF66J?

The MCF5216CVF66J integrates FlexCAN 2.0B, three UART modules, one I²C bus controller, and a Queued Serial Peripheral Interface (QSPI) with four chip selects. It does not include Ethernet MAC or USB. These interfaces support robust industrial networking (CAN), legacy serial (UART), sensor interfacing (I²C), and external Flash/memory expansion (QSPI).

What low-power modes are supported by the MCF5216CVF66J and how do they affect peripheral operation?

The MCF5216CVF66J supports Run, Wait, Doze, and Stop modes. In Wait mode, the core clock halts while peripherals remain active; Doze reduces bus clock frequency; Stop disables all clocks except RTC and selected wake sources. Peripheral behavior - including FlexCAN message buffering and UART receive FIFO retention - is explicitly documented per mode in the User's Manual.

Is the MCF5216CVF66J pin-compatible with other ColdFire devices such as the MCF5282?

No, the MCF5216CVF66J is not pin-compatible with the MCF5282. While both belong to the ColdFire family and share architectural similarities, the MCF5216CVF66J uses a 144-pin LQFP package with specific signal allocation, whereas the MCF5282 is offered in 256-pin PBGA and 176-pin LQFP variants with different pin counts, power domains, and peripheral mappings - requiring distinct PCB layouts.
