These processors are based on Arm Cortex- A7 and Cortex-M4 cores with separate isolated domains and 2D and 3D GPU. Linux OS can run on Cortex-A7 and real-time operating system like FreeRTOS can run on Cortex-M4 core.
Processors have 32 Kbytes of L1 instruction cache memory, 32 Kbytes L1 data cache and 256 Kbytes of L2 cache. There is also sram 512kbyte. Processors support up to 32-bit LPDDR2/LPDDR3 memory interfaces, GPIO, I2C, SPI, UART and USB interfaces. In deep sleep mode, power consumption is 50 µW in optimized configurations, the distributor reports. Reverse and forward bias transistors ensure low leakage and scalability of the operating voltage.
The vendor also offers a system-on-module (som) board that plugs into the corresponding motherboard. The kit is designed to support developers with launching and configuring mobile processor interface (mipi) displays. Som provides 1GB of LPDDR3 memory, 8MB of quad SPI flash memory, micro SD 3.0 memory card slot, Wi-Fi and Bluetooth connectivity, USB 2.0 on the go (otg) with Type-C port and NXP PF1550 power management. IC. The main board contains an audio codec, an HDMI connector, several sensors and a full SD/MMC 3.0 card slot. The kit also includes a bootable SD card with a pre-installed Linux OS. The company also retains NXP for further development and evaluation projects.
