Murata has announced a series of two 2.4GHz IEEE802.11 b/g/n compliant wireless modules based around the TI CC3200 and TI CC3100 SimpleLink chipsets. These miniature modules, measuring 13.2 x 21.45 x 2.65mm are claimed to ease incorporating wireless internet connectivity to a host of embedded applications and especially internet of things (IoT) designs.

Both modules, Type 1JP and Type1JQ, have SPI and UART interfaces, 16Mbit Flash memory and a 40MHz clock. The module is constructed on a PCB with all matching components and a PCB antenna and the wireless transceiver and associated logic enclosed in a metal case. Peripheral interfaces include SPI, UART and numerous GPIO pins for attaching sensors and other devices.

The Type 1JP module uses the TI CC3100 chipset and attaches to a host microcontroller to control communication. The Type 1JQ uses the TI CC3200 chipset that features a Cortex-M4 microcontroller and 256kByte RAM enabling it to operate as a complete ‘host-less’ application.

Both modules are pin-to-pin compatible and will remain compatible with later second-generation modules of Simplelink allowing customers to upgrade their designs without any hardware redesign.
