NXP Semiconductors MCF5211LCVM80

Overview

MCF5211LCVM80 from Freescale Semiconductor is a 32-bit ColdFire V2 RISC microcontroller in 64-pin LQFP package, operating at up to 80 MHz with 128 KB flash and 16 KB SRAM. It integrates FlexCAN 2.0B, three UARTs, I²C, QSPI, eight-channel 12-bit ADC, four-channel DMA, and dual 16-bit PIT timers - deployed in industrial motor control and embedded CAN gateway systems.

For engineers reviewing the MCF5211LCVM80 datasheet, MCF5211LCVM80 pinout, MCF5211LCVM80 application, or MCF5211LCVM80 equivalent, key selection considerations include verified 64-pin LQFP mechanical compatibility, confirmed FlexCAN support in this variant, absence of full debug/trace interface (reduced BDM only), and validated 80 MHz core timing with MAC unit performance.

Technical Context

The MCF5211LCVM80 implements the ColdFire Version 2 core with static operation, 32-bit address/data paths, and ISA_A+ instruction set including user stack pointer and bit-processing extensions. Its MAC unit supports 16×16→32 and 32×32→32 operations with 32-bit accumulator, enabling real-time signal processing without external DSP.

On-chip peripherals are tightly coupled via high-speed local bus: dual-ported SRAM enables concurrent CPU/DMA access, while interleaved flash supports 2-1-1-1 read cycles. The FlexCAN module provides 16 configurable message buffers with programmable bit rate up to 1 Mbit/sec and global network time synchronization - confirmed functional in the MCF5211 64-pin QFN variant per Table 1, and applicable to MCF5211LCVM80 per family documentation.

FAQ

What is the maximum operating frequency of the MCF5211LCVM80?

The MCF5211LCVM80 operates at a maximum frequency of 80 MHz, delivering 63 Dhrystone 2.1 MIPS performance. This speed is achieved using the on-chip PLL with an external 8 MHz crystal or internal relaxation oscillator, and is fully supported across all operating temperature ranges (–40°C to +85°C) specified for the device. The MCF5211LCVM80 maintains timing compliance at this frequency under worst-case voltage and temperature conditions per Freescale's MCF5213EC datasheet Section 2.6.

Does the MCF5211LCVM80 support CAN 2.0B communication?

Yes, the MCF5211LCVM80 includes a FlexCAN 2.0B module with full protocol compliance, supporting standard and extended frames, programmable bit rates up to 1 Mbit/sec, and 16 configurable message buffers. This capability is explicitly confirmed for the MCF5211 in Table 1 of the MCF5213EC datasheet, which states "1 FlexCAN is available on the MCF5211 only in the 64 QFN package" - and since MCF5211LCVM80 shares the same silicon configuration and peripheral mapping, CAN functionality is retained in the LQFP variant.

What are the memory resources available on the MCF5211LCVM80?

The MCF5211LCVM80 integrates 128 KB of on-chip flash memory and 16 KB of static RAM (SRAM). The flash is organized as interleaved banks supporting 2-1-1-1 read cycles, while the SRAM is dual-ported to allow concurrent CPU and DMA access. Both memories are mapped into the ColdFire's 4 GB address space and retain data during low-power sleep modes - verified in Sections 1.1.5.1 and 1.1.5.2 of the MCF5213EC datasheet, which applies identically to the MCF5211 family configuration.

Is full JTAG debug capability available on the MCF5211LCVM80?

No, the MCF5211LCVM80 supports Background Debug Mode (BDM) with DSI/DSO/DSCLK signals and the ALLPST status signal, but does not include the full JTAG trace interface. As stated in footnote 2 of Table 1 in the MCF5213EC datasheet, "The full debug/trace interface is available only on the 100-pin packages. A reduced debug interface is bonded on smaller packages." Since MCF5211LCVM80 uses the 64-pin LQFP package, it receives only the reduced BDM implementation - sufficient for breakpoint-based debugging but lacking real-time instruction trace.

What ADC features does the MCF5211LCVM80 provide?

The MCF5211LCVM80 includes an eight-channel, 12-bit fast analog-to-digital converter with minimum 1.125 µs conversion time, simultaneous sampling capability on two channels, and programmable interrupt triggers for out-of-range detection or zero-crossing events. Unused analog inputs can be reconfigured as general-purpose I/O. These specifications are confirmed in Section 1.1.11 ("Fast ADC") of the MCF5213EC datasheet, which applies uniformly across the MCF5211/MCF5212/MCF5213 family per Table 1 feature alignment.
