NXP Semiconductors MCF5213CAF80

Overview

MCF5213CAF80 from Freescale Semiconductor is a 32-bit ColdFire V2 RISC microcontroller operating at up to 80 MHz, featuring 256 KB flash, 32 KB SRAM, FlexCAN 2.0B, three UARTs, I²C, QSPI, eight-channel 12-bit ADC, and four 32-bit DMA-capable timers. It targets industrial motor control, automotive body electronics, and embedded gateway applications requiring real-time deterministic response and CAN bus integration.

For engineers reviewing the MCF5213CAF80 datasheet, MCF5213CAF80 pinout, MCF5213CAF80 application, or MCF5213CAF80 equivalent, this page delivers verified technical context, package-specific pin mapping (LQFP-64), key timing and memory parameters, functional alternatives for CAN-enabled MCU migration, and supply-chain support for long-lifecycle embedded designs.

Technical Context

The MCF5213CAF80 implements the ColdFire Version 2 core with MAC unit and hardware divider, delivering 76 MIPS (Dhrystone 2.1) at 80 MHz from internal flash. Its integrated clock module includes an 8 MHz on-chip relaxation oscillator and PLL supporting programmable system frequencies from 1–48 MHz.

It integrates a full FlexCAN 2.0B controller with 16 configurable message buffers, three UARTs with FIFO and modem control, and a dual-S/H 12-bit ADC capable of simultaneous two-channel sampling-critical for motor current sensing. All peripherals connect via a high-speed local bus with DMA support across UARTs, timers, and ADC.

FAQ

What is the maximum operating frequency of the MCF5213CAF80?

The MCF5213CAF80 operates at a maximum frequency of 80 MHz. This is achieved using the on-chip PLL with an external crystal or the internal 8 MHz relaxation oscillator. At this speed, the ColdFire V2 core delivers 76 MIPS (Dhrystone 2.1) when executing from internal flash memory, enabling real-time deterministic performance for motor control and communication tasks. The MCF5213CAF80 maintains full functionality-including FlexCAN, ADC, and timers-at rated speed.

Does the MCF5213CAF80 support CAN FD or only classical CAN?

The MCF5213CAF80 implements FlexCAN 2.0B, which supports only classical CAN (ISO 11898-1:2003), not CAN FD. It handles standard (11-bit ID) and extended (29-bit ID) frames with data lengths up to 8 bytes and bit rates up to 1 Mbit/s. CAN FD features such as variable bit rates and payloads >8 bytes are absent. For CAN FD support, newer NXP S32K or MPC57xx families must be considered instead of the MCF5213CAF80.

What package type does the MCF5213CAF80 use, and is it RoHS-compliant?

The MCF5213CAF80 uses the LQFP–64 package: 10 mm × 10 mm body, 0.5 mm lead pitch, with exposed thermal pad. Per Freescale documentation (MCF5213EC Rev. 3), this variant is RoHS-compliant and lead-free. The "CAF" suffix in the part number explicitly denotes the LQFP-64 RoHS-compliant version, distinguishing it from older leaded variants and other packages like MAPBGA-81 or QFN-64.

Can the MCF5213CAF80's ADC perform simultaneous sampling on two channels?

Yes, the MCF5213CAF80's fast ADC supports true simultaneous sampling on two channels using its dual sample-and-hold (S/H) circuits. This capability is explicitly documented in Section 1.1.11 of the MCF5213EC datasheet and is essential for accurate current measurement in three-phase motor control. Both S/H circuits capture voltage at the exact same instant, eliminating phase error between channel conversions - a feature confirmed for the MCF5213CAF80 across all supported LQFP-64 configurations.

Is JTAG debug support fully available on the MCF5213CAF80 LQFP-64 package?

The MCF5213CAF80 in LQFP-64 supports JTAG IEEE 1149.1 boundary-scan testing and basic debug access, but not the full real-time trace interface. As stated in Section 1.1.3 of the MCF5213EC datasheet, the complete debug/trace capability (including PST/DDATA ports and ALLPST signal) is bonded only on 100-pin packages. However, the LQFP-64 retains dedicated debug serial I/O (DSI/DSO/DSCLK) and ALLPST for halted-state detection - sufficient for BDM-based development and production board test.
