IFXCYW43907KWBGT
Overview
The CYW43907KWBGT is a highly integrated single-chip SoC that combines a dual-band 2.4GHz and 5GHz 802.11a/b/g/n Wi-Fi subsystem with a powerful 320MHz Arm Cortex-R4 processor. This device is designed for high-performance IoT applications, featuring 2MB of RAM and a wide array of serial interfaces including Ethernet MAC and USB 2.0. Its 316-pin WLCSP package provides a dense footprint for compact systems requiring robust wireless connectivity and significant local processing power.
Why Choose This Part
It offers superior throughput up to 150Mbps and improved interference mitigation through its dual-band capability. The inclusion of a dedicated Arm Cortex-R4 core with FPU and DSP instructions allows engineers to offload complex application logic directly onto the wireless SoC, reducing system BOM and power consumption.
Applications
Key Specifications
Getting Started
Development is supported through the Infineon ModusToolbox environment, which provides the necessary libraries and middleware for Wi-Fi networking and peripheral control. For hardware evaluation, engineers typically use the CYW943907AEVAL1F evaluation kit to prototype software before moving to custom WLCSP PCB designs.
Also Consider
Espressif Systems
- Lower cost alternative for 2.4GHz-only applications that still require high RAM and integrated Wi-Fi/Bluetooth.
