Product details
Overview
MCF5235CVM100J 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 100 MHz core frequency and 50 MHz bus frequency, supporting industrial control systems requiring deterministic real-time I/O processing and network connectivity.
For engineers reviewing the MCF5235CVM100J datasheet, MCF5235CVM100J pinout, MCF5235CVM100J application, or MCF5235CVM100J equivalent, this page delivers verified electrical specs, validated 256-pin MAPBGA package mapping, confirmed SDRAM/FlexCAN/Ethernet interface capabilities, and direct alternative part guidance for migration from MC68332 or legacy ColdFire designs.
Technical Context
The MCF5235CVM100J 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 message buffers and error handling.
It integrates a 32-channel enhanced Time Processor Unit (eTPU) with 6 KB dedicated RAM for autonomous timing-critical tasks such as motor commutation, PWM generation, and encoder signal processing - all without CPU intervention. The device includes a 2-bank SDRAM controller, four 32-bit DMA timers, and a 4-channel DMA controller optimized for burst transfers between peripherals and memory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | ColdFire V2 32-bit RISC CPU with EMAC unit - enables high-speed arithmetic for motion control and digital power conversion. |
| Max Core Frequency | 100 MHz - delivers up to 92 MIPS (Dhrystone 2.1), sufficient for real-time PLC logic and multi-axis servo coordination. |
| On-chip Memory | 64 KB SRAM + 8 KB unified cache - supports fast data buffering and low-latency interrupt response in deterministic applications. |
| Communication Interfaces | Dual FlexCAN 2.0B, 3 UARTs, QSPI, I²C, FEC with MII/serial PHY support - enables CAN-based fieldbus integration and wired Ethernet backhaul. |
| eTPU Channels | 32-channel eTPU with 6 KB RAM - offloads time-critical I/O (e.g., PWM edge alignment, quadrature decoding) from main CPU. |
| SDRAM Support | 2-bank SDRAM controller with programmable timing - allows expansion to ≥64 MB external memory for HMI or protocol stack buffering. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Active-low reset input | Asynchronous system reset; requires external pull-up and debounced assertion per design recommendations. |

| ETXCLK / ERXCLK | Ethernet transmit/receive clock | MII mode: 25 MHz reference for 100 Mbps operation; must be routed with controlled impedance and minimal skew. |
| CANTX0 / CANRX0 | FlexCAN 0 differential bus interface | CMOS-level signals requiring external ISO 11898-compliant transceiver for physical layer compliance and fault protection. |
| SD_CS0 / SD_SRAS / SD_SCAS | SDRAM chip select & address strobes | Enable synchronous DRAM access; SD_CS0 selects bank 0, SD_SRAS/SD_SCAS latch row/column addresses per JEDEC timing. |
| DT0IN / DT0OUT | DMA timer channel 0 input/output | Configurable for input capture or output compare; used for precise event timestamping or waveform generation independent of CPU. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCF52259CAG80 | Same ColdFire V2 core, but 80 MHz max, no FEC, single CAN, 32 KB SRAM - lacks Ethernet and second CAN channel. | Suitable for CAN-only industrial nodes without Ethernet backhaul; cannot replace MCF5235CVM100J in gateway or PLC roles. | Select when cost sensitivity outweighs need for dual CAN or Ethernet; verify eTPU channel count matches (32 vs 16). |
| Kinetis K66F18M180JMD | ARM Cortex-M4F @ 180 MHz, 1 MB Flash, 256 KB RAM, dual CAN, Ethernet MAC + PHY, no eTPU - different architecture, higher clock, no hardware timing coprocessor. | Better suited for complex protocol stacks (IPv6, TLS) and floating-point math; requires software replacement of eTPU functions. | Choose for new designs needing future-proof ARM ecosystem and security features; not drop-in due to peripheral register map and timing model differences. |
Compared with MCF52259CAG80, the MCF5235CVM100J adds Ethernet and second CAN for gateway functionality; compared with K66F18M180JMD, it retains deterministic eTPU timing but lacks modern security and flash density - making it optimal for legacy ColdFire migration where timing predictability is non-negotiable.

FAQ
What is the maximum operating frequency of the MCF5235CVM100J?
The MCF5235CVM100J is rated for a maximum core frequency of 100 MHz and bus frequency of 50 MHz, as specified in the MCF523x Hardware Specification Rev. 4. This rating assumes proper decoupling, thermal management, and adherence to voltage sequencing guidelines - particularly ensuring OVDD does not lag VDD by more than 0.4 V during power-up.
Does the MCF5235CVM100J include an integrated Ethernet PHY?
No, the MCF5235CVM100J integrates only the Fast Ethernet Controller (FEC) MAC layer. An external PHY IC (e.g., DP83848 or LAN8720) is required for physical layer signaling. The device supports both MII (18-pin) and seven-wire serial interfaces, with pin assignments for ETXCLK, ERXCLK, ETXD[3:0], ERXD[3:0], and management signals EMDC/EMDIO.
How many CAN controllers does the MCF5235CVM100J support?
The MCF5235CVM100J integrates two independent FlexCAN 2.0B modules, each supporting up to 64 message objects and full CAN protocol compliance including error confinement and bus-off recovery. Pins CANTX0/CANRX0 and CANTX1/CANRX1 are dedicated to each module and require external transceivers for physical layer connection.
What package type and pin count does the MCF5235CVM100J use?
The MCF5235CVM100J uses a 256-ball MAPBGA package (15 mm × 15 mm, 1.0 mm pitch), as documented in Figure 6 of the MCF523x Hardware Specification Rev. 4. This package is identical across all MCF523x 256-MAPBGA variants (MCF5233/MCF5234/MCF5235) and supports standard reflow profiles and automated optical inspection.
Is the eTPU in the MCF5235CVM100J software-programmable?
Yes, the 32-channel eTPU in the MCF5235CVM100J is fully programmable via downloadable microcode stored in its dedicated 6 KB RAM. Freescale provides eTPU Development Studio (eTPU-DS) with libraries for common functions like PWM generation, encoder counting, and stepper motor control - enabling customization without modifying the main ColdFire application code.
