(Single-band 802.11 b/g/n/dual-band 802.11 a/b/g/n Wi-Fi, Bluetooth 5 with Cortex-M4F)

Multi-protocol WiSeMCU™ products have an integrated ultra-low power Cortex-M4F, a comprehensive wireless sub-system, advanced security, a rich set of analog and digital peripherals as well as a power management system. The wireless subsystem provides single band Wi-Fi (2.4 GHz, 802.11b/g/n 1x1), dual band Wi-Fi (2.4/5 GHz, 802.11a/b/g/n 1x1), Bluetooth 5. The integrated Cortex-M4F is dedicated to customer applications, has up to 4 MB flash and can operate up to 180 MHz. There is support for Keil and IAR IDEs for customer applications.All of the products are provided in industrial (-40°C to +85°C) temperature range. User also has a choice of several SoCs and module package (with and without antenna) options depending upon the system requirements.

Solution Highlights
• Efficient on-chip application processor based on ARM® Cortex®-M4F with up to 180 MHz performance, up to 4 MB dedicated flash
• Co-existence of multiple wireless protocols including 802.11a/b/g/n (2.4 GHz and 5 GHz), dual-mode Bluetooth 5
• Ultra-low power consumption with multiple power modes to reduce the system energy consumption
• Multiple levels of security including PUF (Physically Unclonable Function), Crypto HW accelerators, Secure Bootloader and Secure Zone to create a highly secure system
• Fully integrated and wireless certified modules with multiple sizes as small as 4.63 mm x 7.90 mm
• Integrated networking and wireless stacks for ease of integration
• Leading edge RF performance providing long range and higher throughputs
• Unique peripherals like ULP sub-system, voice activity detection (VAD) and up to 8 capacitive touch sensor inputs

Symmetry Electronics is an authorized Redpine Signals distributor.
