Product details
Overview
MCF51AG96CQH 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 ADCs (up to 24 channels), two flexible timer modules (FTM1/FTM2), and hardware CRC - enabling deterministic real-time control in space-constrained 64-pin LQFP packages.
For engineers reviewing the MCF51AG96CQH datasheet, MCF51AG96CQH pinout, MCF51AG96CQH application, or MCF51AG96CQH equivalent, key selection criteria include its 64-pin LQFP footprint, 2.7–5.5 V operation, ultra-low-power stop modes, on-chip debug via single-wire BDM, and compatibility with MC9S08AC128 migration paths.
Technical Context
The MCF51AG96CQH 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 supporting 44 peripheral interrupts, independent clocked watchdog (WDOG) with windowed mode, and external watchdog monitor (EWM) for fail-safe external circuit reset.
Peripherals are tightly coupled via DMA: four channels support concurrent transfers with ADC, FTM, SCI, SPI, IIC, HSCMP, RTC, and eGPIO. The ADC operates asynchronously with selectable hardware triggers from RTC, PDB, or iEvent - critical for noise-sensitive industrial sensing.

FAQ
What is the maximum operating frequency of the MCF51AG96CQH?
The MCF51AG96CQH supports a maximum CPU frequency of 50.33 MHz across its full operating voltage range of 2.7 V to 5.5 V. This frequency is achievable using either the internal clock source (ICS) with FLL or an external crystal oscillator (XOSC) in the 1 MHz to 16 MHz range. Performance is validated per the ColdFire V1 ISA_C specification, delivering 0.94 DMIPS/MHz when running from internal RAM.
Does the MCF51AG96CQH support hardware debugging during runtime?
Yes, the MCF51AG96CQH includes a single-wire background debug module (BDM) compliant with ColdFire V1 architecture. It supports real-time debugging with six hardware breakpoints (four PC, one address pair, one data), on-chip trace buffer with programmable start/stop conditions, and debug visibility bus for partial program/data tracing - all accessible without halting CPU execution.
How many analog-to-digital converter channels does the MCF51AG96CQH provide in the 64-pin LQFP package?
In the 64-pin LQFP package, the MCF51AG96CQH provides 19 ADC input channels (ADP0–ADP18). This is confirmed in Table 1 of the MCF51AG128 datasheet, which explicitly lists "19" under the "MCF51AG96 / 64-pin" column for ADC channels. All 19 channels support 12-bit resolution, right-justified output formatting, and hardware-triggered conversions.
Can the MCF51AG96CQH operate in ultra-low-power modes while maintaining peripheral functionality?
Yes, the MCF51AG96CQH supports three ultra-low-power stop modes and a reduced-power wait mode. In Stop3 mode, the ADC, RTC, and I²C can wake the device via address match; the peripheral clock enable register allows selective disabling of unused modules to minimize current draw while retaining active peripherals such as the WDOG or LVD circuitry.
Is the MCF51AG96CQH pin-compatible with other members of the MCF51AG family?
The MCF51AG96CQH shares identical pinout and peripheral mapping with the MCF51AG128 in the 64-pin LQFP package, as confirmed by Tables 1 and 3 in the datasheet. Both devices use the same 64-pin assignment, including RGPIO, FTM, ADC, and communication interface pin functions - enabling direct substitution where flash capacity requirements align.
