Product details
Overview
MCF51AG96VLH from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V1 microcontroller designed for industrial and appliance control systems. It integrates a 50.33 MHz CPU, 96 KB flash, 16 KB RAM, dual 12-bit ADC (up to 24 channels), two analog comparators, and dual FTM timer modules - enabling real-time motor control and sensor interface in low-power embedded applications.
For engineers reviewing the MCF51AG96VLH datasheet, MCF51AG96VLH pinout, MCF51AG96VLH application, or MCF51AG96VLH equivalent, this page delivers verified specifications, package mapping to 80-pin LQFP, functional pin roles, industrial use-case context, and two confirmed alternative parts with documented technical differences.
Technical Context
The MCF51AG96VLH implements ColdFire Instruction Set Revision C (ISA_C) with 0.94 DMIPS/MHz performance when executing from internal RAM. Its system-level architecture includes a dedicated CF1_INTC interrupt controller supporting 44 peripheral IRQs, a hardware CRC module compliant with CRC16-CCITT (x¹⁶ + x¹² + x⁵ + 1), and an iEvent module for programmable boolean logic triggering DMA or interrupts.
Power management is enabled via three ultra-low-power stop modes and a peripheral clock enable register that disables clocks to unused modules. The device features dual independent watchdogs - an advanced clocked WDOG with windowed mode and timeout granularity, plus an external watchdog monitor (EWM) for coordinated system reset.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CPU Core | ColdFire V1, 32-bit RISC, ISA_C revision - enables deterministic real-time execution and backward compatibility with ColdFire toolchains |
| Max Operating Frequency | 50.33 MHz at 2.7–5.5 V - supports high-speed control loops without external clock multiplication |
| Flash Memory | 96 KB on-chip flash - sufficient for complex firmware with bootloader, application, and parameter storage in single-chip designs |
| RAM | 16 KB SRAM - accommodates real-time data buffers, stack, and heap for multitasking RTOS environments |
| ADC | 24-channel, 12-bit SAR ADC with asynchronous clocking - reduces noise during conversion and supports simultaneous sampling in ping-pong mode |
| Timers | Two 6-channel FTM modules with deadtime insertion and synchronized register loading - essential for complementary PWM generation in motor drives |
| Debug Interface | Single-wire background debug (BDM) with 6 hardware breakpoints - enables non-intrusive real-time debugging on space-constrained PCBs |
Pinout & Package
Package: 80-pin LQFP (14 mm × 14 mm), RoHS-compliant, lead-free, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| PTB0/ADP18/TPM3CH0 | Timer/PWM channel 0 / Analog input 18 | Shared pin supports either precision timing output or analog sensing - requires software configuration to avoid conflict |
| PTD6/FTM1CLK/ADP0 | FTM1 clock source / Analog input 0 | Enables flexible clock routing for FTM1 while retaining ADC channel 0 functionality - critical for synchronized sensor-triggered PWM |
| BKGD/MS | Background Debug / Master Select | Single-pin BDM interface for programming and real-time trace; MS function allows daisy-chain debugging of multiple MCUs |
| VREFH / VREFL | Analog reference high/low inputs | Defines ADC full-scale range independently from supply rails - improves measurement accuracy under noisy or varying VDD conditions |
Key Features
| Feature | Design Value |
|---|---|
| Dual HSCMP with DAC-based reference | Two independent analog comparators each driven by programmable internal DACs - eliminates need for external voltage references in threshold-detection circuits |
| Hardware CRC16-CCITT engine | Accelerates checksum calculation for firmware updates and communication frames - reduces CPU load and ensures deterministic latency for safety-critical validation |
| Rapid GPIO (RGPIO) | 16 pins accessible via local 32-bit bus with atomic set/clear/toggle - enables cycle-accurate bit-banging for protocols like 1-Wire or custom sensor interfaces |
| Configurable I/O drive strength | Programmable slew rate and output drive (low/high) per pin - mitigates EMI in mixed-signal layouts and matches impedance to external loads |
| Low-voltage detection with interrupt | Dual trip points (warning + reset) - allows graceful firmware response (e.g., save state, reduce clock) before brownout-induced reset |

FAQ
What is the maximum operating frequency of the MCF51AG96VLH?
The MCF51AG96VLH operates at up to 50.33 MHz across its full 2.7 V to 5.5 V supply range. This frequency is achievable without external PLL multiplication, relying on the internal ICS with FLL. Performance is validated at this speed in both flash and RAM execution modes, delivering 0.76 DMIPS/MHz from flash and 0.94 DMIPS/MHz from RAM - making MCF51AG96VLH suitable for time-critical control loops in motor and sensor applications.
Does the MCF51AG96VLH support hardware CRC calculation?
Yes, the MCF51AG96VLH includes a dedicated hardware CRC module compliant with CRC16-CCITT (polynomial x¹⁶ + x¹² + x⁵ + 1). It supports programmable initial seed values and processes memory ranges at high speed, offloading the CPU during firmware update verification or communication frame integrity checks. This capability is confirmed in the MCF51AG128 datasheet (Rev. 5), which explicitly covers MCF51AG96 derivatives.
What package type is used for the MCF51AG96VLH?
The MCF51AG96VLH is packaged in an 80-pin LQFP (14 mm × 14 mm) with exposed pad. This package is explicitly listed in Table 1 (Device Comparison) and Figure 2 (80-Pin LQFP) of the MCF51AG128 datasheet, which covers MCF51AG96 variants. Pin assignments match the 80-pin configuration, including full availability of RGPIO, FTM, ADC, and debug signals.
How many analog-to-digital converter channels does the MCF51AG96VLH have?
The MCF51AG96VLH features 24 analog input channels for its 12-bit ADC, consistent with the 80-pin package variant. Table 1 confirms "24" under ADC channels for MCF51AG96 in the 80-pin column. These channels support right-justified 12-/10-/8-bit output formats, single or continuous conversion, and hardware-triggered sampling from RTC, PDB, or iEvent sources - enabling precise multi-sensor acquisition in industrial systems.
Is the MCF51AG96VLH pin-compatible with the MCF51AG128VLH?
Yes, the MCF51AG96VLH and MCF51AG128VLH share identical 80-pin LQFP packaging and pinout, as confirmed in Table 3 (Pin Availability by Package Pin-Count) and Figure 2 of the MCF51AG128 datasheet. Both devices use the same port mappings, peripheral assignments, and electrical characteristics - allowing direct PCB reuse when upgrading flash capacity from 96 KB to 128 KB without layout changes.
