Inventek Systems Introduces the ISM43903 Low Cost Wi-Fi Module with Expanded Memory Capability for IoT applications

August 20, 2018- Inventek Systems announces the release of the ISM43903 low cost Wi-Fi module for IoT applications. The ISM43903-R48-L54 is an 802.11 b/g/n, FCC/CE certified Wi-Fi module based on the Cypress CYW43903 embedded wireless system-on-a-chip (SoC). The module includes a 160 MHz ARM Cortex-R4 applications processor with 1MB SRAM, 640 KB ROM, and 64-Mbit SPI Flash Memory, as well as a second processor that supports a single stream IEEE 802.11n MAC/baseband/radio, a power amplifier (PA), a receive low-noise amplifier (LNA), and antenna.

The Internet of Things (IoT) Dual Core module has the memory and performance to support the increasing demand of cloud connected IoT devices, while using advanced design techniques and process technology to reduce active and idle power. The device is designed for embedded applications that require additional host processor performance and minimal power consumption.

The ISM43903-R48-L54-E/U Wi-Fi module requires no operating system and has an integrated TCP/IP stack. The module can be used with Inventek’s IWIN® AT command set or to develop a custom application on the module using Cypress WICED® Studio SDK. The module is offered in two versions: With a 2.4 GHz PCB etched antenna on the module or with a connector for an external antenna. The module has a 14.5mm x 30mm surface mount footprint.

This module is an optimized SoC targeting embedded Internet-of-Things applications in the industrial, medical, sensor, and home appliance markets.

Martin Tierney, Chief Executive Officer at Inventek Systems, expressed his enthusiasm for this family of modules due to the increased RAM and processor performance. “The additional memory resources and increased functionality meet the technical demands of IoT devices worldwide.” said Tierney. “Many of our customers are running into issues with the stack allocation requirements for an embedded system and having enough memory allows you to set the stack up properly, to ensure a stable and reliable system. I’m excited to see what our customers will build using the additional memory of the ISM4390x family” Underestimating stack usage can lead to serious runtime errors and heap memory overflows can have a significant impact on system behavior. These issues are notoriously difficult to debug, and as the IoT ecosystem continues to grow with additional features, security requirements and expanding cloud libraries and protocols, an emphasis must be placed on the importance of this additional memory. Stretching the limits in programming when it comes to allocated data can cause limitations without this additional memory. The advantage of the ISM4390X family of modules is the amount of RAM, ROM and flash that allows software engineers all the memory they need at a competitive price to develop their IoT product.

The ISM43903-R48-L54-E/U is in full production today.
