i.MX 7Dual introduction

i.MX 7Dual Family of Applications Processors Datasheet, Rev. 7, 09/2023

NXP Semiconductors

The i.MX 7Dual family of processors is specifically useful for applications such as:

• Audio

• Connected devices

• Access control panels

• Human-machine interfaces (HMI)

• Portable medical and health care

• IP phones

• Smart appliances

• Point of Sale

• eReaders

• Wearables

• Home energy management systems

The features of the i.MX 7Dual family of processors include the following:

• Arm Cortex-A7 plus Arm Cortex-M4—Heterogeneous Multicore Processing architecture enables

the device to run an open operating system like Linux/Android on the Cortex-A7 core and an RTOS

like FreeRTOS™ on the Cortex-M4 core.

• Two Arm Cortex-A7 cores—The processor enhances the capabilities of portable, connected

applications by fulfilling the ever-increasing MIPS needs of operating systems and applications at

lowest power consumption levels per MHz.

• Multilevel memory system—The multilevel Cortex-A7 memory system is based on the L1

instruction and data caches, L2 cache, and internal and external memory. The processor supports

many types of external memory devices, including DDR3, DDR3L, LPDDR2 and LPDDR3, NOR

Flash, NAND Flash (MLC and SLC), QSPI Flash, and managed NAND, including eMMC rev.

• Power efficiency—Power management implemented throughout the IC enables features and

peripherals to consume minimum power in both active and various low-power modes.

• Multimedia—The multimedia performance is enhanced by a multilevel cache system, NEON™

MPE (Media Processor Engine) coprocessor, a programmable smart DMA (SDMA) controller.

• Up to two Gigabit Ethernet with AVB—10/100/1000 Mbps Ethernet controllers supporting IEEE

Std 1588 time synchronization.

• Electronic Paper Display Controller (EPDC)—The processor integrates an EPD controller that

supports E Ink® color and monochrome panels with up to 2048 x 1536 resolution at 106 Hz

refresh, 4096 x 4096 resolution at 20 Hz refresh, and 5-bit grayscale (32-levels per color channel).

• Human-machine interface (HMI)—i.MX 7Dual processor provides up to two separate display

interfaces (parallel display and two-lane MIPI-DSI), CMOS sensor interface (two-lane MIPI-CSI

and parallel).

• Interface flexibility—i.MX 7Dual processor supports connections to a variety of interfaces: two

high-speed USB on-the-go modules with PHY, High-Speed Inter-Chip USB, multiple expansion

card ports (high-speed MMC/SDIO host and other), two Gigabit Ethernet controllers with support

for Ethernet AVB, PCIe-II, two 12-bit ADCs with a total of 8 single-ended inputs, two CAN ports,

and a variety of other popular interfaces (such as UART, I2C, and I2S).
