NXP Semiconductors MCF52259CVN80

Overview

MCF52259CVN80 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, 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 embedded systems.

For engineers reviewing the MCF52259CVN80 datasheet, MCF52259CVN80 pinout, MCF52259CVN80 application, or MCF52259CVN80 equivalent, key selection criteria include its 144-pin LQFP package, 80 MHz V2 ColdFire core with EMAC/CAU acceleration, FEC + FlexCAN dual-network capability, Mini-FlexBus interface, and support for deterministic real-time I/O via four DMA-capable 32-bit timers and PWM modules.

Technical Context

The MCF52259CVN80 implements the ColdFire ISA_A+ instruction set with a two-pipeline V2 core (IFP/OEP), delivering 76 MIPS 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 for DSP-intensive tasks.

It integrates dual-bus architecture: a high-speed local bus for CPU/SRAM/flash access and a peripheral bus supporting FEC, USB OTG, FlexCAN, UARTs, I²C, QSPI, and ADC. The Mini-FlexBus (available only on 144-pin packages) provides glueless 20-bit address/8-bit data expansion at up to 40 MHz in 1:2 mode, enabling direct connection to external ROM, flash, or logic devices.

FAQ

What is the maximum operating frequency of the MCF52259CVN80?

The MCF52259CVN80 operates at a maximum core frequency of 80 MHz, delivering 76 MIPS (Dhrystone 2.1) when running from internal flash memory. Its Version 2 ColdFire core supports static operation and includes an enhanced multiply-accumulate (EMAC) unit and hardware divider. This frequency is confirmed in the Freescale MCF52259 Rev. 5 datasheet Section 1.1 and Table 1, and applies specifically to the MCF52259CVN80 variant in 144-pin LQFP packaging.

Does the MCF52259CVN80 include hardware cryptographic acceleration?

Yes, the MCF52259CVN80 integrates a Cryptographic Acceleration Unit (CAU) that accelerates DES, 3DES, AES, MD5, and SHA-1 operations in hardware. This coprocessor is tightly coupled to the V2 ColdFire core and significantly reduces encryption/decryption latency compared to software-only implementations. The CAU is explicitly listed in the MCF52259 family feature table (Rev. 5, p.3) and detailed in Section 1.2.6 - and is present in all MCF52259 variants including the MCF52259CVN80.

Which package type does the MCF52259CVN80 use, and what interfaces require it?

The MCF52259CVN80 uses a 144-pin LQFP package (20 mm × 20 mm). This package is required to access the Mini-FlexBus external interface, full FEC pinout (including all MII signals), and complete 96-bit GPIO capability. The 100-pin LQFP variant omits Mini-FlexBus and reduces GPIO count - so the MCF52259CVN80's 144-LQFP is mandatory for designs needing external memory expansion or full Ethernet/CAN I/O. Confirmed in Rev. 5 datasheet Sections 3 and Table 1.

Can the MCF52259CVN80 perform simultaneous analog sampling?

Yes, the MCF52259CVN80's 8-channel 12-bit ADC supports simultaneous sampling on two channels using dual sample-and-hold circuits. This capability is triggered via SYNCA/SYNCB pins and is essential for accurate three-phase motor current measurement. The ADC also supports sequential scanning, programmable thresholds, and zero-crossing interrupts. All these features are documented for the MCF52259CVN80 in Rev. 5 datasheet Sections 1.2.15 and 2.15.

Is USB On-The-Go supported on the MCF52259CVN80, and what modes does it operate in?

Yes, the MCF52259CVN80 includes a USB On-The-Go (USB OTG) controller supporting both full-speed (12 Mbps) and low-speed (1.5 Mbps) operation. It functions as either a USB host or USB device, with 16 bidirectional endpoints and DMA/FIFO data stream interfaces. OTG protocol logic enables peer-to-peer connectivity without a PC host. This functionality is confirmed for the MCF52259CVN80 in Rev. 5 datasheet Sections 1.2.5 and 2.9 - and is identical across all MCF52259 family members.
