Product details
Overview
MIMXRT1015CAF4BR from NXP Semiconductors is an industrial-grade Arm Cortex-M7 crossover processor operating at 396 MHz, featuring 128 KB on-chip RAM (configurable as TCM or OCRAM), integrated DCDC/LDO power management, and dual-channel Quad SPI interface. It delivers real-time deterministic performance for motor control, industrial HMI, and audio edge nodes with 57 GPIOs, three SAI modules, SPDIF I/O, and FlexPWM supporting 16-bit resolution.
For engineers reviewing the MIMXRT1015CAF4BR datasheet, MIMXRT1015CAF4BR pinout, MIMXRT1015CAF4BR application, or MIMXRT1015CAF4BR equivalent, key selection criteria include its -40°C to +105°C junction temperature rating, 100-pin LQFP package with 0.5 mm pitch, USB OTG with integrated PHY, and hardware-accelerated security including AES-128, SHA-256, TRNG, and Secure RTC.
Technical Context
The MIMXRT1015CAF4BR implements a single Arm Cortex-M7 core with 32 KB I-cache, 32 KB D-cache, and VFPv5 FPU, enabling high-throughput deterministic execution. Its memory subsystem includes 96 KB boot ROM, 128 KB FlexRAM configurable in 32 KB granularity across I-TCM/D-TCM/OCRAM, and external memory support via FlexSPI (dual-channel QuadSPI) and parallel NOR/PSRAM interfaces.
Peripherals are organized around centralized IOMUXC for pin multiplexing, with dedicated timer subsystems including two 32-bit General Purpose Timers, one QuadTimer (four 16-bit channels), one FlexPWM (up to 8 PWM channels), and one Quadrature Encoder. Audio is served by three SAI modules (I2S/TDM/AC97), SPDIF Tx/Rx, and MQS for GPIO-based medium-quality audio output.

FAQ
What is the maximum operating frequency of the MIMXRT1015CAF4BR?
The MIMXRT1015CAF4BR operates at a maximum core frequency of 396 MHz. This speed is guaranteed across the full industrial temperature range (-40°C to +105°C) and under specified voltage conditions. The frequency is derived from the internal PLL locked to the 24 MHz crystal input on XTALI/XTALO, and it is not user-overclockable beyond this rated value per the IMXRT1015IEC datasheet Rev. 3.1.
Does the MIMXRT1015CAF4BR support secure boot and firmware encryption?
Yes, the MIMXRT1015CAF4BR includes High Assurance Boot (HAB) and hardware-accelerated cryptographic engines: Data Co-Processor (DCP) for AES-128 (ECB/CBC) and SHA-256, Bus Encryption Engine (BEE) for on-the-fly Quad SPI Flash decryption, and Secure Non-Volatile Storage (SNVS) with tamper-resistant RTC. These features enable authenticated, encrypted boot and runtime firmware integrity verification in the MIMXRT1015CAF4BR.
Can the MIMXRT1015CAF4BR generate audio output without an external DAC?
Yes, the MIMXRT1015CAF4BR integrates Medium Quality Sound (MQS) functionality that generates stereo PWM audio directly from two GPIO pins. This eliminates the need for an external DAC and analog filter in voice UI, status tone, or low-fidelity audio applications-reducing BOM cost and board area while maintaining compatibility with standard speakers driven through simple RC low-pass filters.
What package type and pin count does the MIMXRT1015CAF4BR use?
The MIMXRT1015CAF4BR uses a 100-pin LQFP package measuring 14 mm × 14 mm with 0.5 mm pitch. This package is fully documented in Section 6 of the IMXRT1015IEC datasheet and supports standard reflow soldering processes. Thermal performance is enhanced by an exposed pad on the underside, which must be soldered to a thermal plane per NXP's layout guidelines.
Which communication interfaces are available on the MIMXRT1015CAF4BR for industrial connectivity?
The MIMXRT1015CAF4BR provides four UARTs (including LPUARTs), two I2C modules, two SPI modules, one USB 2.0 OTG controller with integrated PHY, and FlexIO for protocol emulation. These interfaces support industrial connectivity to sensors (I2C/SPI), BLE modules (UART), USB peripherals, and custom serial protocols-all accessible via the 57 GPIOs with configurable pull-up/down and drive strength settings.
