Product details
Overview
MCF5216CVF66 from NXP (formerly Freescale) is a 32-bit ColdFire V2 core microcontroller featuring 128 KB on-chip Flash, 16 KB SRAM, and integrated peripherals including UART, I²C, QSPI, FlexCAN, QADC, and DMA controllers. It operates at up to 66 MHz and supports multiple low-power modes for industrial control and networking edge devices.
For engineers reviewing the MCF5216CVF66 datasheet, MCF5216CVF66 pinout, MCF5216CVF66 application, or MCF5216CVF66 equivalent, key selection criteria include its 66 MHz CPU clock, 128 KB Flash/16 KB SRAM memory map, ColdFire V2 ISA_A+ instruction set, EMAC acceleration unit, and support for external SDRAM via EIM - all critical for deterministic real-time embedded firmware development.
Technical Context
The MCF5216CVF66 implements the ColdFire Version 2 microarchitecture with a 32-bit Harvard-style pipeline, 4 KB unified instruction/data cache, and enhanced multiply-accumulate (EMAC) unit supporting fractional arithmetic. Its memory subsystem includes programmable chip select logic, external interface module (EIM), and synchronous DRAM controller.
System-level integration is enabled by the System Control Module (SCM) managing bus arbitration, privilege access control, and reset/wdog supervision, alongside dedicated modules for FlexCAN 2.0B communication, queued ADC sampling (10-bit, 16-channel), and IEEE 802.3-compliant Fast Ethernet via FEC - though FEC is excluded in MCF5216 versus MCF5282.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF52235CAG80 | Higher clock (80 MHz), 256 KB Flash, 64 KB SRAM, added USB OTG - no FlexCAN or QADC. | Better suited for USB host applications; lacks integrated CAN and high-resolution analog capture needed for industrial fieldbus nodes. | Select when USB connectivity and larger code space outweigh CAN/analog requirements. |
| Kinetis K60DN512ZVMD10 | Cortex-M4 core, 100 MHz, 512 KB Flash, 128 KB SRAM, FPU, 16-bit ADC - no ColdFire ISA compatibility. | Superior floating-point performance and memory bandwidth; requires full firmware porting due to architectural divergence. | Choose for new designs needing DSP math acceleration and modern toolchain support, not ColdFire migration paths. |
Compared with MCF5216CVF66, MCF52235CAG80 trades CAN/QADC for USB and memory headroom, while K60DN512ZVMD10 replaces ColdFire determinism with Cortex-M4 throughput and FPU - both demand hardware and software revalidation for drop-in replacement.

FAQ
What is the maximum operating frequency of the MCF5216CVF66?
The MCF5216CVF66 operates at a maximum core frequency of 66 MHz, achieved via its integrated Phase-Locked Loop (PLL) driven by an external crystal (typically 8–16 MHz). This frequency is specified under commercial temperature range (0°C to +70°C) and 3.3 V ±0.3 V supply conditions, and is validated for sustained operation in real-time control loops without thermal throttling.
Does the MCF5216CVF66 include an integrated Ethernet controller?
No, the MCF5216CVF66 does not include a Fast Ethernet Controller (FEC). That peripheral is present only in the higher-tier MCF5282 variant. The MCF5216CVF66 provides UART, I²C, QSPI, and FlexCAN for wired communication, but requires an external PHY and MAC IC or network controller IC for Ethernet connectivity.
What debug interfaces are supported by the MCF5216CVF66?
The MCF5216CVF66 supports IEEE 1149.1 JTAG Test Access Port and Background Debug Mode (BDM) for full-chip visibility, flash programming, breakpoint insertion, and real-time register inspection. These interfaces are accessible via standard 10-pin or 20-pin BDM connectors and are fully supported by CodeWarrior Development Studio v6.3 and later.
How much user-accessible Flash and RAM does the MCF5216CVF66 provide?
The MCF5216CVF66 integrates 128 KB of on-chip Flash memory (ColdFire Flash Module) and 16 KB of static RAM. All Flash is user-programmable for application code and data storage; SRAM is directly mapped and available for stack, heap, and global variables without external expansion.
Is the MCF5216CVF66 pin-compatible with other ColdFire family members?
No, the MCF5216CVF66 is not pin-compatible with other ColdFire variants such as MCF52235 or MCF5282. While sharing functional blocks, it uses a unique 144-pin LQFP (VF) package layout optimized for its specific peripheral set and memory configuration - PCB redesign is required for substitution.
