For engineers reviewing the MIMXRT1021DAG5A datasheet, MIMXRT1021DAG5A pinout, MIMXRT1021DAG5A application, or MIMXRT1021DAG5A equivalent, key selection criteria include 144-pin LQFP package compatibility, 96 GPIO availability, dual SD/eMMC host support, real-time Ethernet timing, and integrated DCDC/LDO power management for simplified board design.
Technical Context
The MIMXRT1021DAG5A implements a single Arm Cortex-M7 core with 16 KB I-cache, 16 KB D-cache, and VFPv5 FPU, enabling deterministic real-time execution at 500 MHz. Its memory subsystem integrates 96 KB boot ROM and 256 KB flexible RAM mapped across I-TCM, D-TCM, and OCRAM domains.
Peripherals include two FlexCAN modules compliant with CAN 2.0B, one 10/100 ENET controller with IEEE 1588 hardware timestamping, dual uSDHC interfaces supporting 100 MB/s in HS200 mode, three SAI modules for I2S/TDM audio, and dual FlexPWM units delivering up to 24 total 16-bit PWM channels - all accessible via 144-pin LQFP I/O with configurable pin multiplexing.

Pinout & Package
Package: 144-pin LQFP, 20 × 20 mm, 0.5 mm pitch - compatible with standard reflow processes and manual inspection; includes dedicated power/ground planes and thermal pad for stable thermal performance under sustained 500 MHz operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD_SOC | Core logic supply | 1.0–1.3 V input for Cortex-M7 core and TCM; requires tight regulation and local decoupling for noise-sensitive high-speed operation. |
| DCDC_IN | DCDC converter input | 3.3 V input feeding integrated buck regulator; must be asserted ≥1 ms before DCDC_PSWITCH activation per power sequencing requirement. |
| BOOT_MODE0/1 | Boot configuration | Strapped inputs determining boot source (FlexSPI, SD, UART); require external pull-up/down resistors for reliable cold-start behavior. |

FAQ
What is the maximum operating frequency of the MIMXRT1021DAG5A?
The MIMXRT1021DAG5A operates at a maximum frequency of 500 MHz on its Arm Cortex-M7 core. This frequency is guaranteed across the full consumer-grade junction temperature range (0 °C to +95 °C) under specified voltage and cooling conditions, and is enforced by internal clock dividers and PLL configuration registers.
Does the MIMXRT1021DAG5A support dual SD/eMMC interfaces?
Yes, the MIMXRT1021DAG5A integrates two independent uSDHC controllers (uSDHC1 and uSDHC2), both supporting eMMC 4.5 and SD 3.0 standards up to HS200 mode (100 MB/s). This enables simultaneous firmware storage and data logging without CPU arbitration or shared bus contention.
What package type does the MIMXRT1021DAG5A use?
The MIMXRT1021DAG5A uses a 144-pin LQFP package measuring 20 × 20 mm with 0.5 mm pitch. This package provides 96 GPIOs and full access to all major peripherals including dual uSDHC, Ethernet, FlexCAN, and SAI - offering BGA-level functionality in a leaded, rework-friendly form factor.
How does the integrated DCDC converter function in the MIMXRT1021DAG5A?
The MIMXRT1021DAG5A includes an on-die DCDC buck converter accepting 3.3 V input (DCDC_IN) and generating 0.9–1.3 V core supply (VDD_SOC). It requires proper power sequencing: DCDC_IN must be stable ≥1 ms before asserting DCDC_PSWITCH, and output voltage is trimmed via internal registers or external resistor feedback per application requirements.
Is the MIMXRT1021DAG5A pin-compatible with other i.MX RT102x variants?
No - the MIMXRT1021DAG5A (144-pin LQFP) is not pin-compatible with 100-pin LQFP variants like MIMXRT1021DAF5A due to differing pin counts, I/O allocations, and peripheral mappings. While both share the same core and many IP blocks, their physical interfaces and signal assignments are distinct and require separate PCB layouts.
