The Cortex-M4 implements the ARMv7- ME instruction set architecture (ISA) and adds significant capabilities with DSP and SIMD extensions. The ARM Cortex-M4 core provides additional general processing capability to the SoC with lower power and fast interrupt response time. The Cortex-M4 also includes a single-precision floating-point unit (FPU) and two 32-bit system bus interfaces. The Cortex-M4 implementation includes two tightly coupled local memories, two cache memories connected to bus interfaces, 64-bit system bus interconnect, and supports a 32-byte cache line size. ARM Cortex M4 CPU...

Audio (WM8904) The WM8904 is a high performance ultra-low power stereo CODEC optimized for portable audio applications. The device features stereo ground-referenced headphone amplifiers using the Wolfson ‘Class-W’ amplifier techniques. It incorporates an innovative dual-mode charge pump architecture - to optimize efficiency and power consumption during playback. The ground-referenced headphone output eliminates AC coupling capacitors, and both outputs include common mode feedback paths to reject ground noise. Control sequences for audio path setup can be preloaded and executed by an...

Wi-Fi + BT (LWB5™) The VAR-SOM-MX8 contains LSR's pre-certified high-performance Sterling-LWB5™ Dual band 2.4/5 GHz Wi-Fi® and Bluetooth® Smart Ready Multi-Standard Module based upon the Cypress (formerly Broadcom) CYW43353 chipset supporting 802.11 ac/a/b/g/n, BT 2.1+EDR, and BLE 5.2 wireless connectivity. The VAR-SOM-MX8 module realizes the necessary PHY/MAC layers to support WLAN applications in conjunction with a host processor over a SDIO interface. The modules also provide a Bluetooth/BLE platform through the HCI transport layer. Both WLAN and Bluetooth share the same antenna port....

Dual Ethernet MAC and on-board 10/100/1000 Mbps Ethernet Transceiver The SOM can be ordered with an Integrated Ethernet Transceiver connected to ENET0 RGMII signals, Qualcomm Atheros AR8033 or Analog Devices ADIN1300. Please contact sales@variscite.com for inquiries about P/N assembled on your SOM. An additional Ethernet Transceiver can be connected to ENET1 signals exported from SOM connector pins. Connecting an external Ethernet Transceiver requires a single 1.8/2.5V power supply for RGMII interfaces or 3.3V for RMII interface. 5.6.1 Qualcomm Atheros AR8033 Ethernet Transceiver Key...
