ISP5261-WX • Wi-Fi 6 and Bluetooth Low Energy Module (*)

This module act as a fully functioning Bluetooth LE and Wi-Fi radio node, with only a battery required. It forms the core of an autonomous IOT device requiring Bluetooth LE and Wi-Fi connectivity.

This module is based on NXP RW612 single-chip Wi-Fi/Bluetooth LE/802.15.4 Wireless MCU System on Chip (SoC). It integrates a 32-bit ARM Cortex™-M33 CPU running at 260MHz, 4MB of QSPI flash memory, 1.2MB SRAM as well as analog and digital peripherals. Despite the small size of 12 x 12 x 1.8 mm, the module integrates decoupling capacitors, 40 MHz crystal for Wi-Fi and Bluetooth LE and 32.768kHz crystal for low power timing, DC-DC converters, RF matching circuits and a dual-band antenna. Low power consumption and advanced power management enable battery lifetimes up to several months on AA batteries.

Wi-Fi Communication is compliant with the Wi-Fi Alliance specifications for Wi-Fi 6 including the following protocols: IEEE 802.11ax/ac/n/a/g/b/e/i/k/v/w.

Bluetooth LE connectivity is compliant with Bluetooth 5.3, enabling Long Range. ISP5261 Bluetooth LE section can be used either in Peripheral or Central roles and can handle up to 16 simultaneous central/peripheral connections.

802.15.4-2015 radio at 2.4 GHz offers support of Matter over Thread and 128-bit AES security.

The MCU offers the TrustZone technology and is protected by a PUF (Physically Unclonable Function).
