NXP Semiconductors MCF5235CVM150

Overview

MCF5235CVM150 from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 microcontroller with integrated Ethernet MAC, dual FlexCAN 2.0B controllers, 32-channel eTPU, 64 KB SRAM, and 8 KB instruction/data cache. It operates at up to 150 MHz core frequency and 75 MHz bus frequency, supporting industrial control systems requiring deterministic real-time I/O processing and networked communication.

For engineers reviewing the MCF5235CVM150 datasheet, MCF5235CVM150 pinout, MCF5235CVM150 application, or MCF5235CVM150 equivalent, key selection criteria include its 256-pin MAPBGA package, dual CAN + FEC Ethernet interface, eTPU timing precision for motor control, and compatibility with legacy MC68332-based designs requiring performance upgrade paths.

Technical Context

The MCF5235CVM150 implements the ColdFire V2 RISC architecture with an enhanced multiply-accumulate unit and supports full IEEE 802.3 MII and seven-wire serial Ethernet PHY interfaces via its Fast Ethernet Controller (FEC). Its dual FlexCAN modules operate independently under CAN 2.0B protocol with configurable bit rates up to 1 Mbps.

Real-time I/O handling is enabled by the 32-channel enhanced Time Processor Unit (eTPU), which executes dedicated microcode for high-precision waveform generation and capture-critical for motor commutation, PWM synchronization, and encoder signal processing without CPU intervention.

Key Specifications

Pinout & Package

The MCF5235CVM150 is housed in a 256-ball MAPBGA package (15 mm × 15 mm, 1.0 mm pitch) with exposed thermal pad. Pin assignments follow the MCF5235CVMxxx layout per Figure 6 of MCF5235EC Rev. 4, supporting high-density PCB routing and thermal dissipation in embedded control modules.

FAQ

What is the maximum operating frequency of the MCF5235CVM150?

The MCF5235CVM150 operates at a maximum core frequency of 150 MHz and a maximum bus frequency of 75 MHz. This specification is validated across commercial temperature range (0°C to 70°C) and 3.3 V ± 0.3 V supply conditions per the MCF5235EC Rev. 4 datasheet. The PLL configuration supports integer and fractional multiplication ratios to derive these clocks from external crystal or oscillator inputs.

Does the MCF5235CVM150 include an integrated Ethernet PHY?

No, the MCF5235CVM150 integrates only the Fast Ethernet Controller (FEC) MAC layer. An external PHY device (e.g., DP83848 or LAN8720) must be used for physical layer signaling. The MCF5235CVM150 supports both MII and seven-wire serial interfaces to connect to compatible PHYs, with pin mappings defined in Table 4 and Table 5 of the MCF5235EC Rev. 4 specification.

How many CAN interfaces does the MCF5235CVM150 support?

The MCF5235CVM150 supports two independent FlexCAN 2.0B modules, each with full CAN protocol compliance including identifier masking, message buffering, and error confinement. These modules are electrically isolated at the pin level (CANTX0/CANRX0 and CANTX1/CANRX1), allowing simultaneous operation on separate CAN networks without software arbitration.

What is the function of the eTPU in the MCF5235CVM150?

The enhanced Time Processor Unit (eTPU) in the MCF5235CVM150 is a 32-channel, autonomous peripheral that executes microcode to manage high-precision timing tasks-including PWM generation, encoder quadrature decoding, and capture of fast edge transitions-with guaranteed latency under 1 µs. It operates independently of the ColdFire CPU, freeing the core for application logic while ensuring deterministic I/O response.

Is the MCF5235CVM150 pin-compatible with other MCF523x family members?

The MCF5235CVM150 uses the same 256-ball MAPBGA package footprint as MCF5233CVMxxx and MCF5234CVMxxx variants, but it is not fully pin-compatible due to functional differences in peripheral mapping. For example, eTPU pins in MCF5235CVM150 are multiplexed with Ethernet signals (e.g., ETXD1, ERXD0), whereas earlier variants assign those balls to general-purpose functions. Board design must reference Figure 6 of MCF5235EC Rev. 4 for exact pin assignments.
