2 OVERVIEW
The Inventek ISM4343-WBM-L151-EVB is a single-band IEEE 802.11n-compliant
MAC/PHY, BT 4.1 radio and ST Micro STM32F412 MCU Evaluation Board platform.
Channel bandwidth of 20MHz is supported for IEEE 802.11n traffic. 2.4GHz internal
power amplifiers and a Power Management Unit (PMU), with one switching regulator.
The ISM4343-WBM-L151-EVB integrates clock, Wi-Fi/BT and front end into the smallest
form factor LGA Module. The ISM4343-WBM-L151-EVB IEEE 802.11 b/g/n enables
wireless connectivity to the simplest existing sensor products with minimal engineering
effort. ISM4343-WBM-L151-EVB reduces development time, lowers manufacturing costs,
saves board space, simplifies certification compliance, and minimizes customer RF
expertise required during development of target applications.
The ISM4343-WBM-L151-EVB provides the highest level of integration for a wireless
system, with integrated single band Wi-Fi and BT/BLE based on Cypress’ IEEE802.11
b/g/n single-stream and BT/BLE 4.1 with support for antenna diversity and provisions for
supporting future specifications. The ISM4343-WBM-L151-EVB also supports BT 4.2LE
Secure Connection via the Cypress stack. Integrated power amplifiers, LNAs and T/R
switches for the 2.4 GHz WLAN band, are also included, greatly reducing the external
part count, PCB footprint, and cost of the solution.
The ISM4343-WBM-L151-EVB small form-factor solution also minimizes external
components to drive down cost for mass volumes and allows for handheld device flexibility in
size, form and function. Comprehensive power management circuitry and software ensure
the system can meet the needs of high mobile devices that require minimal power
consumption and reliable operations.

The ISM4343-WBM-L151-EVB module includes an ST Micro STM32F412 Cortex M4
MCU. SPI and UART interfaces enable easy connection to an embedded design. The
ISM4343-WBM-L151-EVB module requires no operating system. The ISM4343-WBML151-EVB module also fully supports Cypress’ WICED Platform SDK.
The ISM4343-WBM-L151-EVB is compatible with the Bluetooth Low Energy operating
mode, which provides a dramatic reduction in the power consumption of the Bluetooth
radio and baseband. The primary application for this mode is to provide support for low
data rate devices, such as sensors and remote controls.
The ISM4343-WBM-L151-EVB implements the highly sophisticated Enhanced
Collaborative Coexistence algorithms and hardware mechanisms, allowing for an
extremely collaborative Bluetooth coexistence scheme along with coexistence support
for external radios such as cellular and LTE, GPS, and Ultra-Wideband. An
independent, high-speed UART is provided for the Bluetooth host interface.
