Based on Fully Depleted Silicon on Insulator (FD-SOI) technology, the i.MX 7ULP devices are based on Arm Cortex-A7 and Cortex-M4 cores with separate isolated domains. The devices include both 3D and 2D GPUs. The Cortex-A7 and Cortex-M4 cores allow the processors to run a rich operating system. For example, Linux can run on the Cortex-A7 core, while FreeRTOS runs on the Cortex-M4 core.
The processors have 32 Kbyte L1 cache instruction memory, 32 Kbytes L1 cache data memory, and 256 Kbyte L2 cache, as well as 512 Kbyte SRAM. They are also able to support up to 32-bit LPDDR2/LPDDR3 memory interfaces, GPIO, I2C, SPI, UART, and USB interface types. With a deep sleep suspend power consumption of just 50 µW in optimized configurations, the processors feature low leakage and operating voltage scalability through reverse and forward body biasing of the transistors.
Mouser has also added the i.MX 7ULP Evaluation Kit. With a SOM connected to the baseboard, the evaluation kit is easy to set up and supports reconfiguration for MIPI displays. The SOM has 1 GByte of LPDDR3, 8 MByte Quad SPI flash, a Micro SD 3.0 card socket, Wi-Fi and Bluetooth connectivity, USB 2.0 OTG with Type C connector, and an NXP PF1550 power management IC. The kit’s baseboard adds an audio codec, an HDMI connector, multiple sensors, and a full SD/MMC 3.0 card socket. The kit also includes a bootable SD card preinstalled with a Linux operating system. Mouser also stocks the NXP i.MX7ULP1 MIPI display touch panel.
