Product details
Overview
MCF51JM128VLHR from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V1 microcontroller designed for embedded control in automotive and industrial applications. It operates at up to 50.33 MHz, integrates 128 KB flash and 16 KB SRAM, features USB OTG dual-role capability, CAN 2.0A/B interface, and cryptographic acceleration (CAU/RNGA). It targets migration paths from MC9S08JM60-based 8-bit systems.
For engineers reviewing the MCF51JM128VLHR datasheet, MCF51JM128VLHR pinout, MCF51JM128VLHR application, or MCF51JM128VLHR equivalent, key selection criteria include its 80-pin LQFP package, –40°C to +105°C temperature grade, integrated MSCAN and USBOTG peripherals, and support for rapid GPIO and low-power Stop3 mode operation.
Technical Context
The MCF51JM128VLHR implements the ColdFire V1 core with Instruction Set Revision C (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 circuitry for flexible clock synthesis from crystal (1–16 MHz) or internal reference sources.
System-level integration includes dual I²C modules (up to 100 kbps), two full-duplex SCIs with LIN support, two SPIs with double-buffered TX/RX, and an 8-channel TPM with input capture/output compare/PWM functionality - all accessible via 66 GPIOs including 16-bit Rapid GPIO on the local 32-bit bus.

FAQ
What is the operating temperature range specified for the MCF51JM128VLHR?
The MCF51JM128VLHR is rated for industrial and automotive operation across –40°C to +105°C ambient temperature. This specification is validated per Freescale/NXP qualification standards and applies to all electrical characteristics in the datasheet, including flash endurance, ADC accuracy, and USB OTG timing margins.
Does the MCF51JM128VLHR include hardware cryptographic acceleration?
Yes, the MCF51JM128VLHR integrates a Cryptographic Acceleration Unit (CAU) supporting DES, 3DES, AES, MD5, and SHA-1 algorithms, plus a FIPS-140 compliant Random Number Generator Accelerator (RNGA). These units operate independently of the ColdFire V1 core, enabling concurrent encryption and real-time control execution in the MCF51JM128VLHR.
How many USB endpoints does the MCF51JM128VLHR support in device mode?
In USB device mode, the MCF51JM128VLHR supports 16 bidirectional endpoints with double buffering - including control, bulk, interrupt, and isochronous transfer types. This endpoint architecture enables high-throughput data streaming and concurrent HID/class-compliant peripheral operation within the MCF51JM128VLHR's USB OTG subsystem.
What is the maximum number of ADC channels supported by the MCF51JM128VLHR?
The MCF51JM128VLHR supports up to 12 single-ended ADC input channels with 12-bit resolution. These channels map to dedicated pins (ADP0–ADP11) and can be sampled in single-shot or continuous mode, with hardware-triggered conversion and automatic compare functionality - all fully operational in Stop3 low-power mode.
Is the MCF51JM128VLHR pin-compatible with other members of the MCF51JM family?
No - the MCF51JM128VLHR uses an 80-pin LQFP package, while other variants like MCF51JM128VLH (64-pin LQFP) and MCF51JM128VLD (44-pin LQFP) have different pin counts and layouts. Pin assignments vary significantly across packages; the MCF51JM128VLHR requires its specific 80-pin footprint and cannot be substituted without PCB revision.
