NXP Semiconductors MCF5234CVM100

Overview

MCF5234CVM100 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 microcontroller designed for industrial control systems. It operates at up to 100 MHz core frequency, integrates 64 KB SRAM, 16-channel eTPU, dual FlexCAN 2.0B modules, three UARTs, and a 2-bank SDRAM controller - enabling deterministic real-time motor control in programmable logic controllers.

For engineers reviewing the MCF5234CVM100 datasheet, MCF5234CVM100 pinout, MCF5234CVM100 application, or MCF5234CVM100 equivalent, this page delivers verified electrical characteristics, validated 256-pin MAPBGA package mapping, confirmed eTPU timing capabilities, and direct replacement guidance for legacy MC68332 migration paths.

Technical Context

The MCF5234CVM100 implements the ColdFire V2 RISC architecture with hardware multiply-accumulate (EMAC), 8 KB instruction/data cache, and dual interrupt controllers (INTC0/INTC1). Its eTPU provides 16 independent channels with dedicated 6 KB RAM for high-precision waveform generation and capture.

It supports synchronous DRAM via a 2-bank controller with configurable byte enables (BS[3:0]), includes four 32-bit DMA timers with input capture/compare, and features QSPI, I²C, and FlexCAN interfaces - all mapped to dedicated pins without functional overlap or muxing conflicts in default configuration.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar microcontroller applications.

Compared with MCF5235CVM150, the MCF5234CVM100 omits Ethernet and crypto hardware - reducing cost and power while retaining identical CAN, UART, eTPU, and SDRAM capabilities. Against MCF52259CVM100, it adds SDRAM support and maintains the 256-MAPBGA package for higher I/O density and thermal performance in demanding environments.

Availability

MCF5234CVM100 is available at Aetrix Electronics and suitable for industrial automation, motor control, and railway signaling applications requiring stable component supply across extended product lifecycles.

Supply support for MCF5234CVM100 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

NXP Semiconductors acquired Freescale in 2015 and continues to support ColdFire microcontrollers for industrial and automotive applications with long-term supply commitments.

The MCF523x family was engineered specifically for deterministic real-time control in harsh environments - emphasizing eTPU precision timing, dual CAN redundancy, and SDRAM scalability for next-generation PLCs and motion controllers.

FAQ

What is the maximum operating frequency of the MCF5234CVM100?

The MCF5234CVM100 operates at a maximum core frequency of 100 MHz, derived from an internal PLL driven by an external 4–50 MHz crystal connected to EXTAL/XTAL pins. This yields up to 96 MIPS Dhrystone 2.1 performance while maintaining deterministic interrupt latency under real-time loads.

Does the MCF5234CVM100 include an integrated Ethernet controller?

No, the MCF5234CVM100 does not include an integrated Fast Ethernet Controller (FEC). That feature is present only in the MCF5235CVMxxx variant. The MCF5234CVM100 retains all other peripherals - including dual FlexCAN, three UARTs, QSPI, and SDRAM controller - making it ideal for CAN-based industrial networks without Ethernet requirements.

What package type and pin count does the MCF5234CVM100 use?

The MCF5234CVM100 uses a 256-ball MAPBGA package (15 mm × 15 mm, 1.0 mm pitch) as documented in Figure 5 of the MCF523x Hardware Specification Rev. 4. Pin assignments are fully compatible with other 256-MAPBGA MCF523x variants, enabling shared PCB layout across the family.

How much on-chip SRAM does the MCF5234CVM100 provide, and is it battery-backed?

The MCF5234CVM100 integrates 64 KB of on-chip SRAM configured as four (8Kx16) banks, accessible without wait states. This SRAM is not battery-backed; it loses content on power loss. For non-volatile data retention, external EEPROM or FRAM must be used via SPI or I²C interfaces.

Can the MCF5234CVM100 replace the MC68332 in existing designs?

Yes, the MCF5234CVM100 is positioned as a high-performance upgrade path for MC68332 users. It offers superior MIPS/MHz, larger memory, dual CAN, and eTPU-based timing - though migration requires PCB redesign due to different package (256-MAPBGA vs. 114-QFP) and updated software abstraction layers for peripheral drivers.
