FAQ

What is the maximum operating frequency of the MCF5213CAF66?

The MCF5213CAF66 operates at a maximum frequency of 66 MHz, as specified in Freescale's MCF5213EC Rev. 3 datasheet. This speed is achieved using the on-chip PLL with external crystal or oscillator input, and it delivers 63 MIPS (Dhrystone 2.1). The MCF5213CAF66 uses the ColdFire V2 core with static design, allowing full-speed operation without minimum clock constraints.

Does the MCF5213CAF66 support CAN FD or only classical CAN 2.0B?

The MCF5213CAF66 supports only Classical CAN 2.0B, not CAN FD. Its FlexCAN module implements the full CAN 2.0B protocol specification, including standard and extended frames, programmable bit rates up to 1 Mbps, and 16 configurable message buffers. CAN FD capability was introduced in later ColdFire generations and NXP's S32K series, not in the MCF5213 family.

What package type and pin count does the MCF5213CAF66 use?

The MCF5213CAF66 uses a 64-pin LQFP package (10 mm × 10 mm, 0.5 mm pitch), as confirmed in Freescale's MCF5213EC Rev. 3 datasheet Section 3.1 and Table 1. This variant is distinct from the 81-pin MAPBGA, 100-pin LQFP, and 64-pin QFN versions of the MCF5213 family. The "CAF66" suffix explicitly denotes the 64-pin LQFP configuration with 66 MHz speed grade.

Can the MCF5213CAF66 execute code directly from flash memory?

Yes, the MCF5213CAF66 executes code directly from its 256 KB on-chip flash memory with interleaved access architecture, achieving zero-wait-state operation at 66 MHz when configured per Freescale's timing specifications. The flash module includes dedicated read-only memory controller and backdoor mapping for DMA and EzPort access, eliminating need for external program memory.

Is the MCF5213CAF66 pin-compatible with other MCF5213 variants like MCF5213CAG80?

No, the MCF5213CAF66 is not pin-compatible with MCF5213CAG80. While both share the same ColdFire V2 core and peripheral set, MCF5213CAG80 is offered only in 100-pin LQFP or 81-pin MAPBGA packages - not in 64-pin LQFP. The "F" in MCF5213CAF66 denotes the 64-pin LQFP package, whereas "G" indicates 100-pin LQFP; pin counts, layouts, and power/ground pin distributions differ significantly.
