Qualcomm QCC730M dual-band WiFi 4 and QCC74xM WiFi 6, BLE 5.3, and 802.15.4 modules target low-power and IoT edge devices

Qualcomm has added two new IoT modules to its wireless connectivity product series: the Qualcomm QCC730M ‘micro-power’ WiFi 4 module and the QCC74xM tri-radio module, with both modules designed for smart homes, smart appliances, medical devices, and industrial applications. The Qualcomm QCC730M is a dual-band, micro-power Wi-Fi 4 module with a 60MHz Arm Cortex-M4F MCU, 640kB SRAM, 1.5MB RRAM, hardware crypto accelerator, and secure boot, debug, and storage. Its low-power design is ideal for portable, battery-powered IoT devices like IP cameras, sensors, and smart locks. Based on the Qualcomm QCC730 module, it features a 36-pin LGA package with a PCB antenna or RF connector and supports up to 4MB of optional NOR flash. The Qualcomm QCC74xM is Qualcomm’s “first programmable connectivity module,” integrating a 32-bit RISC-V module, optional stacked memory (PSRAM and NOR flash), and a tri-radio chipset for WiFi 6, Bluetooth 5.3, and IEEE 802.15.4 (Thread and Zigbee).

Microchip PIC32MZ-W1 is a 32-bit MIPS WiFi MCU with 60+ GPIO, USB, CAN Bus, Ethernet, and more

PIC32MZ W1 and WFI32 2.0 Curiosity Board

Microchip recently released the PIC32MZ-W1 wireless MCU along with 20 other WiFi parts, including WiFi MCUs, link controllers, network controllers, and plug-and-play modules. Among them, the PIC32MZ-W1 wireless MCU is the most interesting because of its 32-bit MIPS microAptiv M-class core running at up to 200MHz, advanced hardware security features, and integrated Microchip Trust Platform for secure cloud authentication. Over the years ESP32 MCUs have become the go-to choice for wireless applications. Still, one problem we always have with ESP32 SoCs is their limited GPIO option due to their strapped-out pin structures. But this new MCU has over 60 GPIO pins to work with along with Ethernet MAC, USB, CAN Bus, CANFD, SPI, I2C, SQI, UART, ADC, JTAG, and more. PIC32MZ-W1 wireless MCU specifications MCU MIPS32 M-Class core clocked at 200 MHz 16KB I-Cache, 16KB D-Cache microMIPS mode (up to 35% smaller code size) DSP extensions (4x 64-bit accumulators, single-cycle […]

NXP RW612 Arm Cortex-M33 Wireless MCU offers Wi-Fi 6, Bluetooth 5.4, and 802.15.4 radios

The NXP RW612 is an Arm Cortex-M33 SoC with three radios, namely WiFi 6, Bluetooth 5.4, and 802.15.4 for Thread and Matter connectivity. It also has a small sibling called the RW610 without the 802.15.4 radio. I first came across RW61x chips, when Debashis wrote about the Trimension SR250 UWB chip mentioning it can work with “host processors like NXP’s i.MX, RW61x, and MCX families”. I initially thought it was a typo for the iW612 tri-radio solution introduced in 2022, and the RW612 is indeed similar, but it’s a complete wireless microcontroller/SoC with an Arm Cortex-M33 application core so it can be used independently as a host instead of a companion chip. NXP RW612 and RW610 specifications: MCU sub-system Core – 260 MHz Arm Cortex-M33 with TrustZone-M Memory On-chip 1.2 MB SRAM PSRAM interface for memory expansion Storage – Quad FlexSPI Flash XIP with on-the-fly decryption Peripheral interfaces Up to […]
