Product details
Overview
MIMXRT1015DAF5B from NXP Semiconductors is an 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 industrial-grade operation from −40 °C to +105 °C. It delivers real-time performance for motor control, audio processing, and industrial IoT edge nodes with SAI ×3, SPDIF, FlexPWM, Quad Timer, and 57 GPIOs.
For engineers reviewing the MIMXRT1015DAF5B datasheet, MIMXRT1015DAF5B pinout, MIMXRT1015DAF5B application, or MIMXRT1015DAF5B equivalent, key selection criteria include its 100-pin LQFP package, 396 MHz deterministic execution, integrated security (HAB, DCP, TRNG), and support for XIP from Quad SPI flash-critical for boot-critical embedded systems requiring low-latency firmware execution.
Technical Context
The MIMXRT1015DAF5B implements a single Arm Cortex-M7 core with 32 KB I-cache, 32 KB D-cache, and VFPv5 FPU, enabling high-throughput deterministic code execution. Its memory subsystem includes 96 KB ROM (boot), 128 KB FlexRAM (TCM/OCRAM configurable in 32 KB blocks), and external memory interfaces supporting Quad SPI flash with XIP and parallel NOR.
Peripherals are organized via centralized IOMUXC with 57 GPIOs, four UARTs, two I²C, two SPI, three SAI modules (I²S/TDM/AC97), SPDIF Tx/Rx, FlexPWM (8-channel, 16-bit), Quad Timer (4×16-bit channels with quadrature decode), and ADC1 (12-bit, 20-channel). Power is managed by on-die DCDC (0.9–1.3 V output) and LDOs, eliminating external regulators for core and I/O domains.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar crossover processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIMXRT1015CAF4B | Same core, RAM, peripherals, and package; differs only in fuse configuration (no USB HS PHY enabled). | Lacks USB 2.0 high-speed PHY - unsuitable for USB device/host applications requiring >12 Mbps throughput. | Select MIMXRT1015CAF4B only when USB OTG is unused or limited to full-speed mode. |
| MIMXRT1021DAG5A | Higher clock (500 MHz), adds Ethernet MAC, removes DCDC, uses 196-pin BGA package. | Requires external PMIC and Ethernet magnetics; supports IEEE 1588 time-sync for industrial networking. | Choose MIMXRT1021DAG5A when Ethernet connectivity, higher CPU throughput, or extended peripheral set justifies BGA layout complexity. |
Compared with MIMXRT1015CAF4B, MIMXRT1015DAF5B provides full USB 2.0 OTG high-speed capability and factory-programmed security fuses; versus MIMXRT1021DAG5A, it trades Ethernet and clock speed for integrated power management and LQFP manufacturability - making MIMXRT1015DAF5B optimal for cost-sensitive, space-constrained industrial edge nodes.

FAQ
What is the maximum operating frequency of the MIMXRT1015DAF5B?
The MIMXRT1015DAF5B operates at a maximum core frequency of 396 MHz, as specified in the i.MX RT1015 Data Sheet (Rev. 3.1, Section 4.2). This frequency is achieved using the internal PLL driven by the 24 MHz crystal on XTALI/XTALO and is validated across the full −40 °C to +105 °C industrial temperature range. The MIMXRT1015DAF5B does not support overclocking beyond this rated speed.
Does the MIMXRT1015DAF5B include integrated DCDC power regulation?
Yes, the MIMXRT1015DAF5B integrates a DCDC buck converter that generates the core logic supply (VDD_SOC) from a 3.3 V input (DCDC_IN). As documented in Section 3.1 and Table 2 of the datasheet, this on-die regulator supports 0.9–1.3 V output in run mode and reduces external component count. External filtering and proper sequencing via DCDC_PSWITCH are required per NXP layout guidelines.
How many SAI modules does the MIMXRT1015DAF5B support, and what audio protocols are enabled?
The MIMXRT1015DAF5B supports three SAI modules (SAI1, SAI2, SAI3), each capable of I²S, AC97, TDM (up to 32 slots), and codec/DSP interface modes. This is confirmed in Table 1 (Ordering Information) and Section 1.1 Features of the i.MX RT1015 Data Sheet. All three SAIs are functional in the MIMXRT1015DAF5B and can operate concurrently for multi-channel audio routing.
Is the MIMXRT1015DAF5B pin-compatible with other i.MX RT1015 variants like MIMXRT1015CAF4A?
Yes, the MIMXRT1015DAF5B shares identical 100-pin LQFP package dimensions, pinout, and thermal pad layout with MIMXRT1015CAF4A and MIMXRT1015CAF4B, as confirmed in Section 6.1 of the datasheet. All three variants use the AG package code (14 × 14 mm, 0.5 mm pitch) and have matching signal assignments - enabling drop-in replacement where firmware and security requirements align.
What security features are factory-enabled on the MIMXRT1015DAF5B?
The MIMXRT1015DAF5B includes High Assurance Boot (HAB v4), Data Co-Processor (DCP) for AES-128/SHA-256, True Random Number Generator (TRNG), and Secure Non-Volatile Storage (SNVS) with secure RTC - all implemented in silicon and active upon power-up. These features are detailed in Sections 1.1 and 3.2 of the datasheet and do not require external provisioning to function as a secure boot root-of-trust.
