NXP Semiconductors MCF5211CEP66

Overview

MCF5211CEP66 from Freescale Semiconductor is a 32-bit ColdFire V2 RISC microcontroller in 64-pin LQFP package, operating at 66 MHz with 128 KB flash and 16 KB SRAM. It integrates FlexCAN 2.0B (CAN bus), three UARTs, I²C, QSPI, eight-channel 12-bit ADC, four DMA-capable 32-bit timers, and programmable PWM - deployed in industrial motor control and automotive body electronics.

For engineers reviewing the MCF5211CEP66 datasheet, MCF5211CEP66 pinout, MCF5211CEP66 application, or MCF5211CEP66 equivalent, key selection considerations include its 66 MHz ColdFire V2 core performance (63 MIPS Dhrystone), FlexCAN support limited to 64-pin QFN per documentation, absence of full debug/trace interface (reduced BDM only), and verified 64-pin LQFP mechanical compatibility per Freescale MCF5213EC Rev. 3.

Technical Context

The MCF5211CEP66 implements the ColdFire Version 2 core with MAC unit and hardware divider, delivering 63 MIPS at 66 MHz. Its memory subsystem includes 128 KB on-chip flash (interleaved, SGFM architecture) and 16 KB dual-ported SRAM accessible by both CPU and DMA.

Peripheral integration centers on real-time I/O control: FlexCAN 2.0B with 16 message buffers (only available in 64-pin QFN variant per Table 1), three UARTs with FIFO and modem support, and an eight-channel 12-bit ADC with simultaneous sampling capability for motor phase current sensing.

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Compared with MCF5211CEP66, MCF5211CAG66 adds FlexCAN at the cost of QFN-only availability and different thermal characteristics, while MCF5212CEP66 trades identical packaging for doubled memory and full JTAG - making MCF5211CEP66 the most cost-efficient choice for non-CAN, resource-tight industrial control.

Availability

MCF5211CEP66 is available at Aetrix Electronics and suitable for industrial motor control, automotive body electronics, medical infusion pumps, and energy metering gateways requiring stable component supply across extended product lifecycles.

Supply support for MCF5211CEP66 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Freescale Semiconductor (now part of NXP Semiconductors) is a fabless semiconductor company specializing in embedded processors, analog, and connectivity solutions for automotive, industrial, and networking markets.

The MCF5211CEP66 belongs to the ColdFire V2 microcontroller family, designed specifically for cost-sensitive, real-time embedded applications demanding deterministic performance, low power, and integrated peripherals - excluding CAN in this variant to reduce silicon area and bill-of-materials cost.

FAQ

Does the MCF5211CEP66 support CAN bus communication?

No, the MCF5211CEP66 does not include FlexCAN hardware. According to Table 1 in the MCF5213EC Rev. 3 datasheet, FlexCAN 2.0B is available only on the MCF5211 in the 64-pin QFN package (MCF5211CAG66), not in the LQFP variant. The MCF5211CEP66 pinout and functional block diagram confirm absence of CANRX/CANTX signals.

What is the maximum operating frequency and performance rating of the MCF5211CEP66?

The MCF5211CEP66 operates at a maximum frequency of 66 MHz and delivers 63 MIPS (Dhrystone 2.1) performance. This value is explicitly stated in Table 1 ("MCF5213 Family Configurations") of the MCF5213EC Rev. 3 datasheet under the "5211" column for "Performance (Dhrystone 2.1 MIPS)".

Which package type and dimensions does the MCF5211CEP66 use?

The MCF5211CEP66 uses a 64-pin LQFP package measuring 10 mm × 10 mm with 0.5 mm lead pitch and an exposed thermal pad. This is confirmed in Section 3.1 ("64-pin LQFP Package") and Figure 4 ("64 LQFP and 64 QFN Pin Assignments") of the MCF5213EC Rev. 3 datasheet.

Can the MCF5211CEP66 execute code from internal flash while running at 66 MHz?

Yes, the MCF5211CEP66 supports full-speed execution from its 128 KB on-chip flash memory at 66 MHz. The ColdFire flash module (CFM) uses interleaved access architecture and an optimized ROM controller to achieve zero-wait-state operation - verified in Section 1.1.5.2 and Table 23 ("SGFM Flash Program and Erase Characteristics").

What debug capabilities are available on the MCF5211CEP66?

The MCF5211CEP66 supports Background Debug Mode (BDM) only - it lacks the full JTAG/IEEE 1149.1 test access port and real-time trace interface. As noted in footnote 2 of Table 1 and Section 1.1.3, the complete debug/trace interface is bonded only on 100-pin packages; smaller packages like the MCF5211CEP66 retain BDM serial pins (DSI/DSO/DSCLK) and ALLPST signal.
