MitySOM-335x WiFi-BLECortex-A8 with WiFi & NEON SIMD Coprocessor


The MitySOM-335x WiFi family of highly configurable, small form-factor processor cards feature a Texas Instruments Sitara AM335x Processor and a LS Research TiWi-BLE WiFi and Bluetooth module. The modules include NAND FLASH and DDR3 RAM memory subsystems.   A MitySOM-335x WiFi System on Module (SoM) provides a complete and flexible CPU infrastructure for highly integrated embedded systems.

The onboard AM335x processor provides Cortex-A8 32-bit RISC processor with a NEON SIMD coprocessor. This MPU is capable of running a rich set of real-time operating systems containing software applications programming interfaces (APIs) expected by modern system designers. The ARM architecture supports several operating systems, including Linux, QNX, and Windows Embedded Compact.

Critical Link’s MitySOM-335x family of modules uses Texas Instruments AM3352, AM3354, and AM3359 processors.  Click the diagram below to view the differences between these processors.
