NXP Semiconductors MCF52259CVN80J

Overview

MCF52259CVN80J from NXP (formerly Freescale) is a 32-bit ColdFire V2 RISC microcontroller designed for embedded industrial and networking applications. It operates at up to 80 MHz, integrates 512 KB flash and 64 KB SRAM, features a Fast Ethernet controller (FEC), FlexCAN 2.0B, USB OTG, and an 8-channel 12-bit ADC with simultaneous sampling - enabling real-time motor control and networked edge devices.

For engineers reviewing the MCF52259CVN80J datasheet, MCF52259CVN80J pinout, MCF52259CVN80J application, or MCF52259CVN80J equivalent, key selection criteria include its 144-pin LQFP package, 80 MHz V2 ColdFire core with EMAC/CAU acceleration, FEC + FlexCAN dual-network capability, and support for deterministic real-time I/O via DTIMs and PWM timers.

Technical Context

The MCF52259CVN80J implements the ColdFire ISA_A+ instruction set with a dual-pipeline V2 core (IFP/OEP), delivering 76 MIPS (Dhrystone 2.1) at 80 MHz. Its tightly coupled Cryptographic Acceleration Unit (CAU) offloads DES, 3DES, AES, MD5, and SHA-1 operations, while the EMAC unit supports 32×32→48-bit multiply-accumulate with four 48-bit accumulators.

It integrates a dual-mode USB OTG controller (full-speed/low-speed host/device), a 10/100 Mbps Fast Ethernet Controller with descriptor-ring DMA, and a Mini-FlexBus interface supporting glueless connection to external memory at up to 40 MHz bus clock - available only on 144-pin packages like the CVN80J variant.

Key Specifications

Pinout & Package

The MCF52259CVN80J is housed in a 144-lead LQFP package (20 mm × 20 mm, 0.5 mm pitch), supporting full debug visibility (JTAG/BDM), Mini-FlexBus, FEC, and all high-speed peripherals. Pin functions are multiplexed via PADI module; unused peripheral pins default to GPIO.

FAQ

What is the maximum operating frequency of the MCF52259CVN80J?

The MCF52259CVN80J operates at a maximum core frequency of 80 MHz, delivering 76 MIPS (Dhrystone 2.1) when running from internal flash memory. Its V2 ColdFire core supports static operation, allowing it to halt at any clock cycle without losing state - critical for low-power modes in battery-backed applications. The peripheral bus runs at up to 40 MHz, and the Mini-FlexBus supports 1:1 or 1:2 clocking modes depending on external memory timing requirements. This frequency is confirmed in Table 1 of the Rev. 5 datasheet and applies specifically to the MCF52259CVN80J variant.

Does the MCF52259CVN80J include hardware cryptographic acceleration?

Yes, the MCF52259CVN80J integrates a dedicated Cryptographic Acceleration Unit (CAU) that accelerates DES, 3DES, AES, MD5, and SHA-1 operations in hardware. The CAU acts as a tightly coupled coprocessor to the V2 ColdFire core, reducing encryption/decryption latency by more than 10× compared to software-only implementations. It is explicitly listed in the MCF52259 family configurations table and detailed in Section 1.2.6 of the Rev. 5 datasheet. This feature is present in the MCF52259CVN80J and distinguishes it from earlier ColdFire variants like the MCF52254.

What package type and pin count does the MCF52259CVN80J use?

The MCF52259CVN80J uses a 144-lead LQFP package measuring 20 mm × 20 mm with 0.5 mm lead pitch. This package is explicitly designated in the "Family Configurations" section of the Rev. 5 datasheet and supports full peripheral availability - including Mini-FlexBus, FEC, USB OTG, and JTAG/BDM debug interfaces. It differs from the 100 LQFP and 144 MAPBGA options offered in the same family; the CVN80J suffix confirms the 144 LQFP variant. Pinout details are validated against Figure 1 (Block Diagram) and Package Information section (page 44).

Can the MCF52259CVN80J operate as both a USB host and device?

Yes, the MCF52259CVN80J includes a Universal Serial Bus On-The-Go (USB OTG) controller that supports dual-mode operation - functioning as either a full-speed/low-speed USB host or device. It complies with USB 1.1 and 2.0 specifications, provides 16 bidirectional endpoints, and supports DMA/FIFO data streaming. This capability is documented in Section 1.2.5 and Table 1 of the Rev. 5 datasheet and is enabled in the MCF52259CVN80J without external transceivers. The USB_DP/USB_DM pins integrate the physical layer, simplifying board design for portable or field-serviceable equipment.

What ADC capabilities does the MCF52259CVN80J provide for motor control?

The MCF52259CVN80J features an 8-channel, 12-bit fast ADC with simultaneous sampling on two channels - a key requirement for field-oriented motor control. It achieves minimum conversion time of 1.125 µs and supports synchronized capture via SYNCA/SYNCB triggers. Two independent sample-and-hold circuits feed dual ADCs, enabling precise phase-current measurement with <10 ns inter-channel skew. Unused analog inputs can be repurposed as digital I/O. These specifications are confirmed in Sections 1.2.15 and 2.15 of the Rev. 5 datasheet and apply directly to the MCF52259CVN80J.
