NXP Semiconductors MCF52258VN80

Overview

MCF52258VN80 from NXP (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for industrial control, motor drive, and networked embedded systems. It operates at up to 80 MHz (76 MIPS Dhrystone), integrates 512 KB flash and 64 KB SRAM, and features FlexCAN 2.0B, USB OTG, Fast Ethernet controller (FEC), and an 8-channel 12-bit ADC with simultaneous sampling - enabling real-time closed-loop control in programmable logic controllers and gateway devices.

For engineers reviewing the MCF52258VN80 datasheet, MCF52258VN80 pinout, MCF52258VN80 application, or MCF52258VN80 equivalent, key selection criteria include its 144-pin LQFP package, V2 ColdFire core with EMAC/CAU acceleration, Mini-FlexBus interface availability, dual watchdog timers, and support for deterministic real-time execution in safety-critical firmware deployments.

Technical Context

The MCF52258VN80 implements the ColdFire ISA_A+ instruction set with a two-pipeline V2 core (IFP/OEP), supporting static operation, 32-bit data/address paths, and hardware divider. Its EMAC unit delivers 16×16→32 and 32×32→48 operations with four 48-bit accumulators for DSP-intensive tasks like motor phase current estimation.

On-chip peripherals include a full-featured FlexCAN 2.0B module with 16 configurable message buffers, a Fast Ethernet controller compliant with IEEE 802.3 for 10/100 Mbps operation, and a dual-S/H 12-bit ADC capable of simultaneous sampling on two channels - critical for field-oriented control (FOC) timing accuracy.

FAQ

What is the maximum operating frequency of the MCF52258VN80?

The MCF52258VN80 operates at a maximum core frequency of 80 MHz, delivering 76 MIPS (Dhrystone 2.1) when executing from internal flash memory. This frequency is achieved using the on-chip PLL with an external crystal or oscillator input, and the peripheral bus runs at up to 40 MHz. The device supports static operation, allowing it to halt the core clock while retaining register and memory contents during low-power modes.

Does the MCF52258VN80 include hardware cryptographic acceleration?

Yes, the MCF52258VN80 integrates a Cryptographic Acceleration Unit (CAU) that offloads DES, 3DES, AES, MD5, and SHA-1 operations from the main ColdFire V2 core. This coprocessor significantly reduces encryption/decryption latency and CPU load, making the MCF52258VN80 suitable for secure firmware updates, encrypted telemetry, and authentication protocols in industrial edge nodes.

Which packages are supported for the MCF52258VN80?

The MCF52258VN80 is specifically offered in a 144-lead LQFP package (20 mm × 20 mm, 0.5 mm pitch), designated by the "VN" suffix. While the broader MCF52259 family includes variants in 100 LQFP and 144 MAPBGA, the MCF52258VN80 part number maps exclusively to this LQFP configuration - confirmed in Freescale Document MCF52259 Rev. 5, Section 3 (Package Information).

Can the MCF52258VN80 support simultaneous analog sampling?

Yes, the MCF52258VN80 features an 8-channel, 12-bit fast ADC with two independent sample-and-hold circuits, enabling true simultaneous sampling on two channels. This capability is triggered via SYNCA and SYNCB pins and is essential for accurate current sensing in three-phase motor control applications where phase alignment directly impacts field-oriented control performance.

Is the Mini-FlexBus interface available on the MCF52258VN80?

Yes, the Mini-FlexBus external bus interface is fully implemented on the MCF52258VN80 and is available on its 144 LQFP package. It supports glueless interfacing to 8-bit ROM, flash, or SRAM with up to 2 MB address space, programmable base address and wait states, and operates at up to 40 MHz in 1:2 mode - providing flexible memory expansion without external logic.
