NXP Semiconductors MCF5212CAE66

Overview

MCF5212CAE66 from Freescale Semiconductor is a 32-bit ColdFire V2 RISC microcontroller operating at 66 MHz, featuring 256 KB flash, 32 KB SRAM, FlexCAN 2.0B, three UARTs, I²C, QSPI, eight-channel 12-bit ADC, four DMA-capable 32-bit timers, and integrated PLL clock generation - deployed in industrial motor control and automotive body electronics.

For engineers reviewing the MCF5212CAE66 datasheet, MCF5212CAE66 pinout, MCF5212CAE66 application, or MCF5212CAE66 equivalent, key selection criteria include confirmed 66 MHz core frequency, LQFP-64 package mapping, FlexCAN compliance with ISO 11898-1, 12-bit ADC conversion time ≤1.125 μs, and full BDM/JTAG debug support per Rev. 3 documentation.

Technical Context

The MCF5212CAE66 implements the ColdFire Version 2 core with MAC unit and hardware divider, delivering 63 MIPS (Dhrystone 2.1) at 66 MHz. Its on-chip memory subsystem includes dual-ported 32 KB SRAM accessible by CPU and DMA simultaneously, and 256 KB interleaved flash supporting 2-1-1-1 read access timing.

Peripheral integration follows a tightly coupled architecture: FlexCAN operates independently with 16 configurable message buffers and programmable bit rates up to 1 Mbps; the 12-bit ADC supports simultaneous two-channel sampling for motor phase current sensing; and the four DTIM modules provide 12.5 ns resolution timing with input capture/output compare and DMA trigger capability.

FAQ

What is the maximum operating frequency of the MCF5212CAE66?

The MCF5212CAE66 operates at a fixed maximum frequency of 66 MHz, as specified in Table 1 (MCF5213 Family Configurations) of the MCF5213EC Rev. 3 datasheet. This frequency is achieved using the on-chip PLL with an external crystal or the internal 8 MHz relaxation oscillator. The MCF5212CAE66 does not support 80 MHz operation - that capability is exclusive to the MCF5213 variant.

Does the MCF5212CAE66 support CAN FD or only classical CAN 2.0B?

The MCF5212CAE66 supports only classical CAN 2.0B protocol as implemented in the FlexCAN module, with bit rates up to 1 Mbps and full compliance with ISO 11898-1. It does not support CAN FD features such as variable bit rate or extended data length - those capabilities were introduced in later ColdFire generations like the MCF5441x series.

What package type is used for the MCF5212CAE66?

The MCF5212CAE66 uses the LQFP–64 package, measuring 10 mm × 10 mm with 0.5 mm lead pitch, as confirmed in the "MCF5213 Family Configurations" section and mechanical drawings (Section 3.1) of the MCF5213EC Rev. 3 datasheet. This package is distinct from the 64 QFN, 81 MAPBGA, and 100 LQFP variants offered in the same family.

Can the MCF5212CAE66's ADC perform simultaneous sampling on more than two channels?

No - the MCF5212CAE66's ADC supports simultaneous sampling on exactly two channels using its dual sample-and-hold circuits, as described in Section 1.1.11. While it has eight analog input channels (AN[7:0]), only two can be captured at the exact same instant; additional channels require sequential sampling with inter-channel delay.

Is the MCF5212CAE66 pin-compatible with the MCF5213CAG80?

Yes - the MCF5212CAE66 and MCF5213CAG80 share identical LQFP–64 pin assignments, electrical characteristics, and peripheral register maps, as verified in Table 3 (Pin Functions) and Figure 4 of the MCF5213EC Rev. 3 datasheet. Both parts use the same 64-pin footprint and support identical signal routing, enabling frequency-upgrade board reuse.
