ST公司的SPBTLE-1S是蓝牙Smart v4.2非常低功耗系统级芯片(SoC)应用处理器模块,基于高性能超低功耗Cortex-M0 32位处理核,嵌入可编程160KB闪存和24KB RAM,和BT标准v4.2和BDE兼容,最大发送功率+ 5 dBm,以微型尺寸集成了无线电,嵌入天线和高频振荡器,提供完整的RF平台.主要用在物联网(IoT),智能家居,建筑物和工业自动化,智能照明,健美和健身与体育,消费类医疗电子,PC和智能手机外设以及安全系统.本文介绍了SPBTLE-1S主要特性和框图,评估板STEVAL-IDB007V1M主要特性和主要元件,电路图,材料清单.

The SPBTLE-1S is a Bluetooth® low Energy System-on-Chip application processor certified module, compliant with BT specifications v4.2 and BQE qualified. The SPBTLE-1S module supports multiple roles simultaneously and can act at the same time as Bluetooth Smart master and slave device.

The SPBTLE-1S is based on BlueNRG-1 system-on-chip and entire Bluetooth Low Energy stack and protocols are embedded into module.

The SPBTLE-1S module provides a complete RF platform in a tiny form factor. Radio, embedded antenna and high frequency oscillators are integrated to offer a certified solution to optimize the time to market of the final applications.

The SPBTLE-1S can be powered directly with a pair of AAA batteries or any power source from 1.7 to 3.6 V.

The SPBTLE-1S is a Bluetooth Low Energy application processor module compliant with Bluetooth® specifications v4.2 with embedded ceramic antenna.

The SPBTLE-1S module has been designed around the ST BlueNRG-1 SoC where its Cortex-M0 core can execute both Bluetooth protocols and customer application. A complete power-optimized Bluetooth stack library provides:

 Master, slave, multiple roles support
 GAP: central, peripheral, observer or broadcaster roles
 Simultaneous advertising and scanning
 capability of being slave of up to two masters simultaneously
 ATT/GATT: client and server
 SM: privacy, authentication and authorization
 L2CAP
 Link Layer: AES-128 encryption and decryption

The SPBTLE-1S has 160 KB embedded Flash and 24 KB embedded RAM memory.
In the module are available 32 MHz and 32 KHz crystal oscillators. It has been designed to leverage the BlueNRG-1 integrated DC-DC step down converter in order to achieve best power consumption in active mode.

It can be configured to support both application processor (host-less) and network processor (hosted) modes.

Being based on the BlueNRG-1 SoC, the SPBTLE-1S module leverages all the tools and documentation of its ecosystem: Development Kit, Application Notes, User Manuals, Design Notes & Tips. A wide set of sample programs are also available in C source code.

The SPBTLE-1S module has a wide set of peripherals available for customer application (1 x UART interface, 1 x SPI interface, 2 x I2C interface, 14 GPIO, 2 x multifunction timer, 10- bit ADC, Watchdog & RTC, DMA controller, PDM stream processor).

The SPBTLE-1S module enables wireless connectivity into electronic devices, not requiring any RF experience or expertise for integration into the final product. The SPBTLE-1S module provides a complete RF application platform in a tiny form factor (11.5 x 13.5 x 2.0 mm) and being a certified solution optimizes the time to market of the final applications.

The SPBTLE-1S module allows applications to meet the tight advisable peak current requirements imposed with the use of standard coin cell batteries. Optimized results are obtained with the embedded high-efficiency DC-DC step-down. SPBTLE-1S can be powered directly with a standard 3 V coin cell battery as with a pair of AAA batteries or any power source from 1.7 to 3.6 V.
