NXP Semiconductors MCF5234CVM150J

Overview

MCF5234CVM150J from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 microcontroller designed for industrial control systems. It operates at up to 150 MHz core frequency and 75 MHz bus frequency, integrates 64 KB SRAM, a 2-bank SDRAM controller, four 32-bit DMA timers, dual FlexCAN 2.0B modules, three UARTs, and a queued SPI interface.

For engineers reviewing the MCF5234CVM150J datasheet, MCF5234CVM150J pinout, MCF5234CVM150J application, or MCF5234CVM150J equivalent, key selection criteria include its 256-pin MAPBGA package, eTPU-based real-time I/O processing, Ethernet-ready FEC support (in superset MCF5235), and compatibility with MC68332 migration paths in motor control and PLC designs.

Technical Context

The MCF5234CVM150J implements the ColdFire V2 RISC architecture with an enhanced multiply-accumulate (EMAC) unit and dual interrupt controllers (INTC0/INTC1). Its eTPU provides 16 dedicated channels with 6 KB of local memory for time-critical peripheral offloading, including PWM generation and encoder interfacing.

It supports synchronous DRAM via a configurable 2-bank SDRAM controller with programmable timing, and features a flexible external interface module (EIM) with chip select logic for NOR/NAND flash, SRAM, and peripherals. The device lacks integrated Fast Ethernet Controller (FEC) and cryptography modules-features reserved for the MCF5235 variant.

Key Specifications

Compared with MCF5235CVM150, the MCF5234CVM150J omits Ethernet and crypto but retains identical eTPU capability and SDRAM support-making it ideal for CAN-based industrial controllers where those features add cost without benefit. Versus MCF52259CAG80, it delivers higher performance, larger memory, and advanced peripherals at the expense of package size and layout complexity.

FAQ

What is the maximum operating frequency of the MCF5234CVM150J?

The MCF5234CVM150J operates at a maximum core frequency of 150 MHz and a maximum bus frequency of 75 MHz. This specification is validated under industrial temperature range (–40°C to +105°C) with proper power supply sequencing and decoupling as defined in Freescale's MCF523x Hardware Specification Rev. 4. The MCF5234CVM150J achieves up to 144 Dhrystone 2.1 MIPS at this speed.

Does the MCF5234CVM150J include an integrated Ethernet controller?

No, the MCF5234CVM150J does not include a Fast Ethernet Controller (FEC). That feature is exclusive to the MCF5235 variant. The MCF5234CVM150J retains all other major peripherals-including dual FlexCAN, three UARTs, QSPI, and SDRAM controller-but omits FEC and the cryptography module to optimize cost and power for CAN-centric industrial applications.

What package type and pin count does the MCF5234CVM150J use?

The MCF5234CVM150J uses a 256-ball Mold Array Process Ball Grid Array (MAPBGA) package, case number 1128A-01, with 15 mm × 15 mm body dimensions and 1.0 mm ball pitch. Pin assignments match the MCF5233/MCF5235 256-MAPBGA variants, enabling layout reuse across the family where compatible peripherals are used.

How much on-chip SRAM does the MCF5234CVM150J provide, and how is it organized?

The MCF5234CVM150J integrates 64 KB of on-chip SRAM, organized as four independent (8K × 16)-bit banks. This configuration enables zero-wait-state access for code and data, supports simultaneous read/write operations across banks, and facilitates efficient memory-mapped peripheral buffering-critical for high-speed CAN and UART throughput in the MCF5234CVM150J.

Is the MCF5234CVM150J pin-compatible with the MCF5235CVM150?

Yes, the MCF5234CVM150J is pin-compatible with the MCF5235CVM150 in the 256-MAPBGA package. All signal pins, power pins, and mechanical dimensions match exactly. However, functionality differs: MCF5235CVM150 adds FEC, cryptography, and 32-channel eTPU-so software and external circuitry must account for missing features when substituting MCF5234CVM150J into an MCF5235 design.
