ST launched single chip antenna matching IC, Bluetooth LE SoC and STM32 wireless MCU, make RF design easier and faster

     STMicroelectronics Single antenna matching IC series added two new optimized products for BlueNRG-LPS system chip (SoC), and STM32WB1x and STM32WB5x series wireless MCU. Monolithic antenna matching IC helps simplify RF circuit design. The BlueNRG-LPx system chip can be used independently or in conjunction with a network processor and supports Bluetooth Low Energy 5.3 features, including point-to-point and mesh communication, AD extension, and direction finding.

     MLPF-NRG-01D3 optimized for BlueNRG-LPS and MLPF-WB-02D3 optimized for STM32WB integrate an external antenna with the complete filtering and impedance matching circuits needed to achieve optimal RF output power and receive sensitivity. Each device has a nominal antenna side impedance of 50Ω. Wafer size package area is small, convex point spacing is 0.4mm, and package height after reflow welding is 630µm. Stmicroelectronics's new antenna matching IC also has a 2.4GHz low-pass filter that easily meets global radio regulatory requirements, including FCC, ETSI and ARIB specifications.

     The new IC circuit component is manufactured on the glass substrate using the integrated passive device (IPD) technology of STMicroelectronics. This design can minimize the signal insertion loss, and the performance is better than that of the circuit constructed using discrete components. Integrating all components on the same chip also ensures consistency of component parameters and quality of the end product. In addition, STMicro's IPDs help speed time to market, reduce bill of materials costs, and reduce circuit size.

     The BlueNRG-LP and BlueNRG-LPS SoC, as well as the STM32WB1x and STM32WB5x, contain a high energy efficiency 2.4GHz RF IP core from stmicroelectronics, complete with royalty-free stack and dedicated software tools. So that RF design inexperienced developers can easily and quickly develop advanced wireless products. Both products offer on-chip features such as memory, peripherals, communication interfaces, regulated power supplies, and advanced hardware security features including encryption, memory protection, and public key acceleration (PKA).

     STM32WB5x and STM32WB1x MCU are wireless dual-core microcontrollers certified by Bluetooth 5.3, Zigbee 3.0 and OpenThread. Arm® Cortex®-M4 processor kernel handles application tasks. The Cortex-M0+ kernel specialises in managing RF communications protocols and is packaged in WLCSP and UFBGA, enabling direct connection to MLPF-WB-02D3 IPDs. For connecting UQFN and VQFN packaged MCUS, STMicroelectronics also provides a different IPD chip.
