Product details
Overview
MCF51AG96CLH from NXP Semiconductors (formerly Freescale) is a 32-bit ColdFire V1 microcontroller designed for industrial and appliance control systems. It integrates 96 KB flash, 16 KB RAM, dual 12-bit ADCs (up to 24 channels), two flexible timer modules (FTM1/FTM2), and a hardware CRC engine. Operates at up to 50.33 MHz across 2.7–5.5 V supply, supporting ultra-low-power stop modes and real-time debug via single-wire BDM.
For engineers reviewing the MCF51AG96CLH datasheet, MCF51AG96CLH pinout, MCF51AG96CLH application, or MCF51AG96CLH equivalent, this page delivers verified specifications, package-confirmed pin functions, validated alternative parts, and application-specific design value - all grounded in the official MCF51AG128/MCF51AG96 Rev. 5 datasheet covering both derivatives.
Technical Context
The MCF51AG96CLH implements the ColdFire Instruction Set Revision C (ISA_C) with 0.94 DMIPS/MHz performance when executing from internal RAM. Its system integration module (SIM) manages clock gating, reset sources (including windowed WDOG and EWM), and low-voltage detection with interrupt/reset options.
Peripheral subsystems include a 4-channel DMA controller servicing ADC, SCI, SPI, FTM, HSCMP, and RTC; an iEvent module enabling programmable boolean logic for interrupt/DMA triggering; and dual analog comparators (HSCMP1/HSCMP2) with internal DAC reference generation and DMA support.
Key Specifications

FAQ
What is the maximum operating frequency of the MCF51AG96CLH?
The MCF51AG96CLH operates at up to 50.33 MHz across its full 2.7–5.5 V supply range. This frequency is achievable with the internal clock source (ICS) configured in FLL mode using either internal or external reference, and is validated per the electrical characteristics in the Rev. 5 datasheet. The MCF51AG96CLH maintains full peripheral functionality and timing compliance at this maximum clock rate.
Does the MCF51AG96CLH support hardware-based cyclic redundancy check (CRC)?
Yes, the MCF51AG96CLH includes a dedicated hardware CRC module compliant with CRC-CCITT (x¹⁶ + x¹² + x⁵ + 1). It performs 16-bit CRC calculations on memory ranges or data streams in a single cycle, enabling fast firmware image validation and error detection in serial communications. This capability is documented in Section 1.3 and Table 2 of the MCF51AG128 Rev. 5 datasheet, which explicitly covers the MCF51AG96 derivative.
How many analog-to-digital converter (ADC) channels does the MCF51AG96CLH provide?
The MCF51AG96CLH provides up to 24 single-ended analog input channels with 12-bit resolution. This count is confirmed in Table 1 ("MCF51AG128 Series Device Comparison") of the Rev. 5 datasheet, which lists "24" under ADC channels for the MCF51AG96 in 80-pin and 64-pin packages. Channel availability scales with package size: 24 in 80-pin LQFP, 19 in 64-pin, and 12 in 48-pin variants.
What debug interface does the MCF51AG96CLH use, and is JTAG supported?
The MCF51AG96CLH uses a single-wire Background Debug Mode (BDM) interface, not JTAG. This is part of the ColdFire V1 core architecture and is detailed in Section 1.3 ("Features") and Table 2 of the Rev. 5 datasheet. BDM provides full real-time debug capability including six hardware breakpoints and on-chip trace, with minimal pin count - eliminating the need for multi-pin JTAG headers in space-constrained designs.
Is the MCF51AG96CLH pin-compatible with the MCF51AG128 series?
Yes, the MCF51AG96CLH is fully pin-compatible with the MCF51AG128 in identical package variants (e.g., 80-pin LQFP). Table 1 and Figure 2 of the Rev. 5 datasheet confirm identical pin assignments, peripheral mappings, and electrical characteristics between the two derivatives. Firmware and hardware designs targeting MCF51AG128 can be deployed on MCF51AG96CLH without layout changes - subject to flash size constraints.
