NXP Semiconductors MCF5211LCEP66

Overview

MCF5211LCEP66 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 (64 QFN only), three UARTs, I²C, QSPI, eight-channel 12-bit ADC, four DMA timers, and programmable PWM for industrial motor control and embedded automation.

For engineers reviewing the MCF5211LCEP66 datasheet, MCF5211LCEP66 pinout, MCF5211LCEP66 application, or MCF5211LCEP66 equivalent, key selection criteria include its 66 MHz V2 ColdFire core performance (63 MIPS Dhrystone), on-chip memory configuration, peripheral set completeness per package variant, and FlexCAN availability constraints.

Technical Context

The MCF5211LCEP66 implements the ColdFire Version 2 core with MAC unit and hardware divider, delivering deterministic real-time execution at 66 MHz. Its integrated peripherals include a full-featured QSPI master, three UARTs with FIFO and modem support, and an eight-channel 12-bit ADC with simultaneous sampling capability for motor phase current sensing.

Power management includes static operation, sleep/stop modes, and per-peripheral clock gating. The interrupt controller supports 57 sources with programmable priority and vectoring, while the debug interface provides BDM and JTAG (reduced pinout) for in-circuit development without emulator dependency.

FAQ

Does MCF5211LCEP66 support FlexCAN 2.0B?

No, MCF5211LCEP66 does not include the FlexCAN 2.0B module. According to Freescale's MCF5213EC datasheet Table 1, FlexCAN is available on the MCF5211 only in the 64 QFN package variant. The MCF5211LCEP66 uses the 64-pin LQFP package, which omits FlexCAN. Engineers requiring CAN must select MCF5212LCEP66 or MCF5213LCEP80 instead.

What is the maximum operating frequency of MCF5211LCEP66?

The MCF5211LCEP66 operates at a maximum core frequency of 66 MHz, delivering 63 MIPS (Dhrystone 2.1). This is confirmed in Table 1 of the MCF5213EC datasheet under "MCF5211" row and "System Clock" column. The device achieves this speed using the ColdFire Version 2 core with on-chip PLL and supports stable operation across industrial temperature ranges.

How much on-chip memory does MCF5211LCEP66 integrate?

MCF5211LCEP66 integrates 128 KB of on-chip flash memory and 16 KB of dual-ported static RAM. These values are explicitly listed in Table 1 of the MCF5213EC datasheet for the MCF5211 configuration. The flash supports in-system programming via EzPort, and the SRAM allows concurrent CPU and DMA access for real-time data buffering.

Is MCF5211LCEP66 pin-compatible with other ColdFire MCF521x devices in 64-pin LQFP?

Yes, MCF5211LCEP66 shares identical 64-pin LQFP mechanical dimensions and pinout with MCF5212LCEP66 and MCF5213LCEP66. All three variants use the same 10 mm × 10 mm LQFP package with 0.5 mm pitch and match pin-for-pin for power, clock, reset, GPIO, UART, QSPI, I²C, ADC, and debug signals. Functional differences (e.g., memory size, FlexCAN presence) do not affect physical compatibility.

What debug interfaces are supported by MCF5211LCEP66?

MCF5211LCEP66 supports Background Debug Mode (BDM) via dedicated DSI/DSO/DSCLK pins and IEEE 1149.1 JTAG boundary scan with reduced pin count. While the full debug/trace interface is limited to 100-pin packages, the 64-pin LQFP retains essential BDM and JTAG functionality for firmware download, breakpoint debugging, and board-level continuity testing as specified in Section 1.1.3 and 1.1.4 of the MCF5213EC datasheet.
