Product details
Overview
MCF51JM128EVQH from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V1 microcontroller designed for embedded control in automotive and industrial applications. It integrates 128 KB flash, 16 KB SRAM, USB OTG, CAN 2.0B, cryptographic acceleration (CAU), and a 12-bit 12-channel ADC. It operates up to 50.33 MHz at 2.7–5.5 V and supports –40°C to +105°C operation in a 64-pin QFP package.
For engineers reviewing the MCF51JM128EVQH datasheet, MCF51JM128EVQH pinout, MCF51JM128EVQH application, or MCF51JM128EVQH equivalent, key selection criteria include its dual-role USB OTG interface, hardware CAU/RNGA support for secure boot, CAN+USB coexistence in compact 64-pin QFP, and compatibility with legacy MC9S08JM60-based designs requiring 32-bit upgrade paths.
Technical Context
The MCF51JM128EVQH implements the ColdFire V1 core (ISA_C), delivering 0.76 Dhrystone MIPS/MHz from flash and supporting up to 30 peripheral interrupts. Its multipurpose clock generator (MCG) includes FLL/PLL with internal reference trimming (0.2% resolution), enabling flexible clock sourcing from crystal (1–16 MHz), external oscillator, or internal RC.
System-level integration includes MSCAN with five RX buffers and three prioritized TX buffers, USB OTG with on-chip 3.3 V regulator and pull-ups, and dual I²C/SPI/SCI peripherals. The device supports Stop3 low-power mode with RTC, CMT, ACMP, and ADC operational-enabling battery-backed real-time sensing and infrared remote control functions without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 32-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Kinetis K22FN512VLH12 | ARM Cortex-M4F core, 120 MHz, 512 KB flash, no CAU but has CRC and RNG; USB OTG same, CAN present | Higher performance and memory; lacks dedicated CMT for IR - requires software PWM or external modulator | Preferred for new designs needing higher throughput or RTOS scalability; not drop-in due to core architecture and peripheral register map differences |
| MCF51JM64VQH | Same ColdFire V1 core, package, and peripheral set; reduced flash (64 KB) and no CAU/RNGA enabled | Identical footprint and pinout; suitable where crypto/security features are unnecessary and cost reduction is critical | Valid pin-compatible alternative when application code size ≤64 KB and FIPS-140 compliance is not required |
Compared with K22FN512VLH12 and MCF51JM64VQH, the MCF51JM128EVQH uniquely combines ColdFire deterministic real-time behavior, hardware IR modulation (CMT), and certified crypto acceleration in a mature 64-pin QFP - making it optimal for cost-sensitive, security-aware, and IR-integrated legacy-upgrade designs.

FAQ
What is the operating temperature range for the MCF51JM128EVQH?
The MCF51JM128EVQH is rated for –40°C to +105°C ambient operation, validated per Freescale's industrial/automotive qualification standards. This range applies to all specified electrical characteristics including CAN, USB OTG, and ADC performance - making it suitable for under-hood automotive modules and factory-floor industrial controllers where thermal margins are critical.
Does the MCF51JM128EVQH include cryptographic hardware acceleration?
Yes, the MCF51JM128EVQH includes a Cryptographic Acceleration Unit (CAU) and Random Number Generator Accelerator (RNGA), both enabled in this part number (denoted by the "E" suffix). The CAU offloads DES, 3DES, AES, MD5, and SHA-1 operations, while the RNGA delivers FIPS-140-compliant 32-bit random numbers - essential for secure boot and firmware authentication in the MCF51JM128EVQH.
Is the MCF51JM128EVQH pin-compatible with other packages in the MCF51JM128 family?
No - the MCF51JM128EVQH uses a 64-pin QFP package, while other variants use 80-pin LQFP, 64-pin LQFP, or 44-pin LQFP. Although pin functions overlap significantly (e.g., CAN, USB, and reset signals appear across packages), mechanical dimensions, pin count, and pin assignments differ. Migration between packages requires PCB redesign; only same-package variants (e.g., MCF51JM128VQH) are pin-compatible with the MCF51JM128EVQH.
What debug interface does the MCF51JM128EVQH support?
The MCF51JM128EVQH supports a single-wire Background Debug Mode (BDM) interface via the BKGD/MS pin. This allows full non-intrusive debugging, flash programming, and real-time trace using standard Freescale/NXP BDM tools - no JTAG header or additional pins required. The interface is fully supported in CodeWarrior Development Studio and modern open-source GDB toolchains with appropriate BDM probes.
Can the MCF51JM128EVQH operate in low-power modes while maintaining CAN or USB functionality?
The MCF51JM128EVQH supports Stop3 mode with RTC, CMT, ACMP, and ADC active, but CAN and USB modules are disabled in all stop modes. CAN wakeup is supported from Wait mode (not Stop), and USB suspend/resume is handled in Run or Wait modes only. For always-on CAN monitoring, designers must use Wait mode with selective clock gating - achieving ~100 µA typical current while retaining CAN bus activity detection.
