NXP Semiconductors MCF52258VN80J

Overview

MCF52258VN80J from NXP (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for industrial control and connectivity applications. It operates at up to 80 MHz, 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 motor control and networked embedded systems.

For engineers reviewing the MCF52258VN80J datasheet, MCF52258VN80J pinout, MCF52258VN80J application, or MCF52258VN80J equivalent, key selection considerations include its 144-pin LQFP package, Mini-FlexBus interface availability, CAU cryptographic acceleration, dual watchdog timers, and support for deterministic real-time execution via DTIM and GPT peripherals.

Technical Context

The MCF52258VN80J implements the ColdFire V2 core (ISA_A+), featuring a two-pipeline architecture (IFP/OEP), EMAC unit with four 48-bit accumulators, and hardware divider - delivering 76 MIPS at 80 MHz. It supports static operation, 32-bit address/data paths, and 16 general-purpose registers.

On-chip subsystems include a dual-port SRAM accessible by CPU, DMA, FEC, and USB; a 512 KB interleaved flash module with backdoor programming via EzPort; and integrated debug with BDM, JTAG, and real-time trace on 144-pin packages. The device includes two independent 16-bit periodic interrupt timers (PITs), a 32 kHz RTC with Vstby support, and programmable clock generation with PLL and relaxation oscillator.

FAQ

What is the maximum operating frequency of the MCF52258VN80J?

The MCF52258VN80J operates at a maximum core frequency of 80 MHz, achieving 76 MIPS (Dhrystone 2.1) when executing from internal flash memory. Its peripheral bus runs at up to 40 MHz, and the Mini-FlexBus supports up to 80 MHz in 1:1 mode. This frequency is enabled by the integrated PLL and verified across commercial temperature range (–40°C to +85°C).

Does the MCF52258VN80J support Ethernet connectivity out of the box?

Yes, the MCF52258VN80J includes a fully integrated Fast Ethernet Controller (FEC) supporting 10/100 BaseT/TX in half- or full-duplex mode. However, it requires an external PHY transceiver (e.g., KSZ8041) and proper magnetics to complete the physical layer. The FEC provides on-chip transmit/receive FIFOs and dedicated DMA for zero-copy packet handling.

Can the MCF52258VN80J perform simultaneous analog measurements?

Yes, the MCF52258VN80J features an 8-channel 12-bit ADC with two independent sample-and-hold circuits, enabling true simultaneous sampling of two channels - critical for accurate current/voltage phase measurement in motor control. This capability is hardware-synchronized via SYNCA/SYNCB pins and does not rely on software sequencing.

Is cryptographic acceleration available on the MCF52258VN80J?

Yes, the MCF52258VN80J includes a Cryptographic Acceleration Unit (CAU) that offloads DES, 3DES, AES, MD5, and SHA-1 operations from the main CPU. This hardware accelerator significantly reduces encryption/decryption latency and power consumption - essential for secure boot, firmware authentication, and TLS stack implementation in resource-limited edge devices.

What debug interfaces does the MCF52258VN80J support?

The MCF52258VN80J supports Background Debug Mode (BDM) and IEEE 1149.1 JTAG for boundary scan and emulation. On the 144-pin LQFP package, it also provides full real-time trace capability via PST/DDATA ports and ALLPST signal - enabling non-intrusive instruction tracing and timing analysis without halting CPU execution.
