Overview
MIMXRT1024CAG4B from NXP Semiconductors is an industrial-grade Arm® Cortex®-M7 crossover processor operating at 396 MHz, integrating 4 MB on-chip flash, 256 KB configurable on-chip RAM (TCM/OCRAM), and dual FlexCAN interfaces. It delivers real-time deterministic performance for motor control, industrial HMI, and secure IoT edge nodes requiring integrated power management and audio I/O.
For engineers reviewing the MIMXRT1024CAG4B datasheet, MIMXRT1024CAG4B pinout, MIMXRT1024CAG4B application, or MIMXRT1024CAG4B equivalent, key selection considerations include its -40°C to +105°C industrial temperature rating, 144-pin LQFP package with 90 GPIOs, dual eMMC/SDHC support, and hardware-accelerated security features including AES-128, SHA-256, and High Assurance Boot.
Technical Context
The MIMXRT1024CAG4B implements a single Arm Cortex-M7 core with 16 KB instruction and 16 KB data caches, full VFPv5 FPU, and MPU supporting up to 16 protection regions. Its memory subsystem includes 96 KB boot ROM, 4 MB flash, and 256 KB FlexRAM configurable as I-TCM, D-TCM, or OCRAM in 32 KB granularity.
It integrates dual FlexCAN 2.0B controllers, one 10/100 Mbps Ethernet MAC with IEEE 1588 support, three SAI modules (I2S/TDM/AC97), SPDIF Tx/Rx, and two 12-bit ADCs with 19 total channels. Power management includes on-die DCDC and LDO regulators, eliminating external PMIC requirements for many industrial designs.

FAQ
What is the maximum operating frequency of the MIMXRT1024CAG4B?
The MIMXRT1024CAG4B operates at a maximum frequency of 396 MHz under industrial temperature conditions (-40°C to +105°C). This frequency is guaranteed across the full junction temperature range and is supported by the on-chip PLL and voltage regulation circuitry. The MIMXRT1024CAG4B does not support overclocking beyond this rated speed, and all timing specifications in the datasheet assume operation at or below 396 MHz.
Does the MIMXRT1024CAG4B include on-chip flash memory?
Yes, the MIMXRT1024CAG4B integrates 4 MB of on-chip flash memory, eliminating the need for external boot devices in most applications. This flash is used for storing firmware, configuration data, and assets, and supports XIP (execute-in-place) operation for critical real-time code. The MIMXRT1024CAG4B flash is qualified for 100,000 erase/write cycles and retains data for 20 years at 85°C.
What package type and pin count does the MIMXRT1024CAG4B use?
The MIMXRT1024CAG4B uses a 144-pin LQFP package measuring 20 × 20 mm with 0.5 mm pitch. This package provides 90 GPIOs and is optimized for industrial PCB assembly, thermal management, and debug accessibility. Pin assignments are documented in Section 7 of the IMXRT1024IEC datasheet and the i.MX RT1024 Reference Manual (IMXRT1024RM).
How does the MIMXRT1024CAG4B handle power management for industrial applications?
The MIMXRT1024CAG4B integrates a complete power management solution including an on-die DCDC converter (accepting 3.3 V input) and multiple LDOs, reducing external component count and simplifying power sequencing. It supports dynamic voltage scaling, low-power stop modes, and hardware-controlled power domain isolation - enabling reliable operation in thermally constrained industrial enclosures without external PMICs.
Which security features are hardware-accelerated in the MIMXRT1024CAG4B?
The MIMXRT1024CAG4B includes hardware-accelerated security features: Data Co-Processor (DCP) for AES-128 (ECB/CBC) and SHA-256; Bus Encryption Engine (BEE) for on-the-fly QSPI flash decryption; High Assurance Boot (HAB) for signed image validation; and Secure Non-Volatile Storage (SNVS) with tamper-resistant RTC and master key storage. These functions operate independently of the Cortex-M7 core, ensuring deterministic security without CPU overhead.
