Product details
Overview
MCF5232CVM100J from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V2 microcontroller with 64 KB SRAM, 16-channel eTPU, four 32-bit DMA timers, three UARTs, FlexCAN 2.0B, and QSPI - designed for deterministic real-time industrial control systems requiring precise timing and I/O event handling.
For engineers reviewing the MCF5232CVM100J datasheet, MCF5232CVM100J pinout, MCF5232CVM100J application, or MCF5232CVM100J equivalent, this page delivers verified package mapping (196 MAPBGA), core clock specification (100 MHz), FlexCAN interface details, eTPU channel count, and validated alternative microcontrollers for migration or second-sourcing.
Technical Context
The MCF5232CVM100J implements the ColdFire V2 RISC architecture with an enhanced multiply-accumulate (EMAC) unit and operates at a maximum core frequency of 100 MHz (as indicated by the '100' suffix in the part number). It integrates dual interrupt controllers (INTC0/INTC1), edge-port module (EPORT), and external interface module (EIM) for flexible memory expansion.
Its 16-channel enhanced Time Processor Unit (eTPU) executes time-critical I/O tasks independently of the CPU, supporting motor control, encoder interfacing, and PWM generation with sub-microsecond resolution. The device lacks Ethernet (FEC) and cryptography modules - distinguishing it from MCF5234/MCF5235 variants.
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 algorithms. |
| Max Core Frequency | 100 MHz - confirmed by '100' in part number and electrical characteristics tables; determines instruction throughput and real-time response latency. |
| SRAM | 64 KB on-chip static RAM - sufficient for real-time task stacks, buffers, and firmware execution without external memory dependency. |
| eTPU Channels | 16-channel enhanced Time Processor Unit - offloads precise timing-critical I/O (e.g., PWM sync, capture, waveform generation) from main CPU. |
| FlexCAN Interfaces | 1 × FlexCAN 2.0B controller - supports CAN bus communication up to 1 Mbps for industrial networking and automotive subsystems. |
| UARTs | 3 × UART modules - enables simultaneous serial diagnostics, host communication, and fieldbus protocol bridging (e.g., Modbus RTU). |
| Package | 196-ball MAPBGA (15 mm × 15 mm, 1.0 mm pitch) - surface-mount package optimized for high-density industrial PCB layouts with thermal and signal integrity advantages over QFP. |
Pinout & Package
196-ball Mold Array Process Ball Grid Array (MAPBGA), case number 1128A-01, 15 mm × 15 mm body, 1.0 mm ball pitch, 1.25–1.60 mm height. Pin 1 identified by laser mark per Figure 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RESET | Active-low reset input | Asynchronous system reset; requires external pull-up and debounced assertion for reliable boot initialization. |
| EXTAL / XTAL | Crystal oscillator inputs | Supports fundamental-mode quartz crystals (4–50 MHz); internal PLL generates 100 MHz core clock - critical for timing accuracy and jitter-sensitive applications. |
| CANTX / CANRX | FlexCAN differential bus interface | CMOS-level signals requiring external CAN transceiver (e.g., TJA1050) for ISO 11898-2 physical layer compliance. |
| U1TXD / U1RXD | UART1 transmit/receive | Full-duplex asynchronous serial interface; supports RS-232/RS-485 level-shifting via external drivers for industrial field connectivity. |
| TPUCH[15:0] | eTPU channel I/O pins | 16 dedicated pins for eTPU input capture, output compare, and waveform generation - mapped to GPIO ports A/B/C/D with configurable pull-ups. |
| VDD / OVDD / VDDPLL | Power supply domains | VDD (1.5 V core), OVDD (3.3 V I/O), VDDPLL (1.5 V PLL) - require strict sequencing (OVDD/VDDPLL track to 0.9 V before separating) to prevent ESD diode conduction. |
Key Features
| Feature | Design Value |
|---|---|
| 16-channel eTPU with 6 KB local RAM | Enables autonomous, cycle-accurate timing control for motor commutation, encoder quadrature decoding, and multi-phase PWM - eliminating CPU polling overhead. |
| Dual 32-bit interrupt controllers (INTC0/INTC1) | Supports prioritized, nested interrupts with low-latency response (< 1 µs) for hard real-time task scheduling in PLC and motion control applications. |
| Four 32-bit DMA timers with dedicated channels | Provides independent, hardware-triggered periodic events (e.g., ADC sampling, servo update) without CPU intervention or timer register reload overhead. |
| QSPI interface with four chip selects | Enables direct connection to serial flash (e.g., Winbond W25Q32) for secure firmware storage and fast code execution from XIP mode. |
| Edge Port Module (EPORT) with programmable edge detection | Allows GPIO pins to generate interrupts on rising/falling edges - ideal for emergency stop monitoring, limit switch scanning, and pulse counting. |
| External Interface Module (EIM) with 4 chip selects | Supports parallel NOR flash, SRAM, and FPGA interfaces up to 75 MHz bus speed - extends memory and peripheral addressing for complex control systems. |

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, 80 MHz max, 128 KB Flash, 32 KB RAM, no eTPU - uses standard timers and GPIO-interrupts instead of dedicated time processor. | Lacks hardware-accelerated timing peripherals; unsuitable for sub-µs PWM or encoder capture but lower cost for non-deterministic control. | Select when eTPU is unnecessary and Flash-based firmware persistence is required over SRAM-only execution. |
| Kinetis K60DN512ZVMD10 | ARM Cortex-M4 core, 100 MHz, 512 KB Flash, 128 KB RAM, 2× CAN, 6× UART, no eTPU - includes FPU and DSP instructions but relies on software-timed peripherals. | Requires RTOS and careful ISR optimization to match MCF5232CVM100J's deterministic eTPU latency; better suited for algorithm-heavy applications than pure timing-critical I/O. | Choose for new designs needing long-term NXP support, USB host capability, or floating-point math - not for drop-in replacement. |
Compared with MCF5232CVM100J, MCF52259CAG80 trades eTPU determinism for integrated Flash and lower power, while K60DN512ZVMD10 offers modern ARM toolchain compatibility and richer peripherals at the cost of increased software complexity for time-critical tasks.

FAQ
What is the maximum operating frequency of the MCF5232CVM100J?
The MCF5232CVM100J operates at a maximum core frequency of 100 MHz, as denoted by the '100' suffix in its part number and confirmed in the electrical characteristics section of the MCF523x Hardware Specification. This frequency is generated internally via the PLL from an external crystal (e.g., 25 MHz) and defines the instruction execution rate and real-time response capability of the MCF5232CVM100J.
Does the MCF5232CVM100J include on-chip Flash memory?
No, the MCF5232CVM100J contains 64 KB of on-chip SRAM but no embedded Flash memory. Firmware must be loaded externally - typically from serial flash via QSPI or parallel memory via the External Interface Module (EIM). This SRAM-only architecture enables zero-wait-state execution but requires external non-volatile storage for program persistence, a design choice aligned with deterministic boot and runtime behavior in the MCF5232CVM100J.
How many CAN interfaces does the MCF5232CVM100J support?
The MCF5232CVM100J integrates one FlexCAN 2.0B controller, supporting CAN protocol up to 1 Mbps with full message buffering and error handling. This is confirmed in Table 1 (MCF523x Family Configurations) where MCF5232 is listed with "1" under the FlexCAN column. Unlike MCF5233/MCF5235 variants, the MCF5232CVM100J does not support dual CAN, making it suitable for single-bus industrial networks.
What package type and pin count does the MCF5232CVM100J use?
The MCF5232CVM100J uses a 196-ball MAPBGA package (case number 1128A-01), measuring 15 mm × 15 mm with 1.0 mm ball pitch. This is explicitly documented in Section 6.1 ("Pinout-196 MAPBGA") and Figure 2 of the MCF523x Hardware Specification. The 'VM' in the part number denotes this MAPBGA variant, distinguishing it from QFP packages used by other MCF5232 derivatives.
Is the eTPU in the MCF5232CVM100J identical to that in higher-end MCF523x devices?
Yes, the MCF5232CVM100J implements the full 16-channel eTPU with 6 KB of dedicated eTPU RAM, matching the eTPU configuration specified for MCF5232 in Table 1. While MCF5233/MCF5235 offer 32-channel eTPU, the MCF5232CVM100J's 16-channel implementation is functionally complete - supporting all eTPU microcode instructions, input capture, output compare, and waveform generation features documented in the MCF5235 Reference Manual.
