NXP Semiconductors MCF5213CAF66R

Overview

MCF5213CAF66R from Freescale Semiconductor is a 32-bit ColdFire V2 RISC microcontroller in 64-pin LQFP package, operating up to 66 MHz with 256 KB flash and 32 KB SRAM. It integrates FlexCAN 2.0B, three UARTs, I²C, QSPI, 8-channel 12-bit ADC, four 32-bit DMA timers, and four-channel GPT - deployed in industrial motor control and automotive body electronics.

For engineers reviewing the MCF5213CAF66R datasheet, MCF5213CAF66R pinout, MCF5213CAF66R application, or MCF5213CAF66R equivalent, key selection considerations include its 66 MHz ColdFire V2 core performance (63 MIPS Dhrystone), on-chip 8 MHz relaxation oscillator with PLL, 56 GPIO pins, and full FlexCAN support without external transceiver dependency.

Technical Context

The MCF5213CAF66R implements the ColdFire Version 2 ISA_A+ core with MAC unit and hardware divider, delivering deterministic real-time execution at 66 MHz. Its dual-pipeline architecture (IFP/OEP) enables efficient instruction fetch and operand execution, while the 32-bit address/data bus supports direct access to on-chip memories and peripherals without wait states.

System-level timing is governed by a configurable clock module featuring an internal 8 MHz relaxation oscillator, external crystal support (1–48 MHz), and PLL with programmable pre-divider (1–8). The FlexCAN module operates at up to 1 Mbps with 16 configurable message buffers, and the 8-channel 12-bit ADC achieves 1.125 µs conversion time with simultaneous sampling capability for dual-channel motor phase sensing.

FAQ

What is the maximum operating frequency of the MCF5213CAF66R?

The MCF5213CAF66R is rated for a maximum core clock frequency of 66 MHz, delivering 63 MIPS (Dhrystone 2.1) performance. This frequency is achieved using the internal PLL locked to either the 8 MHz on-chip relaxation oscillator or an external crystal source. The 'F66' suffix in the part number explicitly denotes the 66 MHz speed grade, confirmed in Table 1 of the MCF5213EC datasheet Rev. 3.

Does the MCF5213CAF66R include an integrated CAN controller?

Yes, the MCF5213CAF66R integrates a full FlexCAN 2.0B module with 16 configurable message buffers, programmable bit rates up to 1 Mbps, and hardware timestamping. It supports both standard and extended frames and requires only an external CAN transceiver (e.g., TJA1042) for physical layer compliance - no additional protocol controller IC is needed. This capability is documented in Sections 1.1.7 and 1.7 of the MCF5213EC datasheet.

How many analog-to-digital converter channels does the MCF5213CAF66R support?

The MCF5213CAF66R supports eight analog input channels (AN0–AN7) with 12-bit resolution and a minimum conversion time of 1.125 µs. It features two independent sample-and-hold circuits enabling simultaneous sampling of two channels - essential for motor phase current measurement. Unused analog inputs can be reconfigured as digital I/O pins, as specified in Section 1.1.11 of the MCF5213EC datasheet.

What debug interfaces are supported on the MCF5213CAF66R in the 64-pin LQFP package?

The MCF5213CAF66R in 64-pin LQFP supports Background Debug Mode (BDM) via dedicated DSI, DSO, and DSCLK pins, plus the ALLPST signal for halt-state detection. While the full JTAG/trace interface is limited to 100-pin packages, the BDM channel enables real-time in-circuit debugging, breakpoint setting, and memory inspection without requiring external emulators. This configuration is detailed in Section 1.1.3 of the MCF5213EC datasheet.

Is the MCF5213CAF66R pin-compatible with other members of the MCF5213 family?

Yes, the MCF5213CAF66R shares identical pinout and electrical characteristics with other 64-pin LQFP variants in the MCF5213 family, including the MCF5213CAG80R (80 MHz) and MCF5213CAE66R (industrial temperature range). All share the same mechanical outline (Figure 4), pin functions (Table 3), and power/ground assignments (Table 18), enabling drop-in frequency or temperature grade upgrades without PCB revision.
