On Semi公司的RSL10是超低功耗的多协议无线系统级芯片(SoC),采用ARMR CortexR−M3处理器(48MHz)和LPDSP32 DSP核(音频CODEC),支持蓝牙5.0低功耗技术和2.4GHz多协议堆栈,Rx接收灵敏度-94dBm,数据速率62.5-2000kbps,发送功率-17到+6dBm,工作电压1.1-3.3V,主要用在可穿戴,物联网(IoT),无线使能低压设备和汽车电子.本文介绍了RSL10主要特性,框图和架构图,应用电路图,以及IoT IDK BLERSL10评估板BLE-IOT-GEVB主要特性,电路图,材料清单和PCB设计图.

RSL10 is an ultra−low−power, highly flexible multi−protocol2.4 GHz radio specifically designed for use in high−performancewearable and medical applications. With its ARMR CortexR−M3Processor and LPDSP32 DSP core, RSL10 supports Bluetooth lowenergy technology and 2.4 GHz proprietary protocol stacks, withoutsacrificing power consumption.

RSL10主要特性:

• Data Rate: 62.5 to 2000 kbps
• Transmitting Power: −17 to +6 dBm
• Peak Rx Current = 5.6 mA (1.25 V VBAT)
• Peak Rx Current = 3.0 mA (3 V VBAT)
• Peak Tx Current (0 dBm) = 8.9 mA (1.25 V VBAT)
• Peak Tx Current (0 dBm) = 4.6 mA (3 V VBAT)
• Bluetooth 5 Certified with LE 2M PHY Support
• ARM Cortex−M3 processor clocked up to 48 MHz
• LPDSP32 for Audio Codec
• Supply Voltage Range: 1.1 − 3.3 V
• Current Consumption (1.25 V VBAT):
♦ Deep Sleep, IO wake−up: 50 nA
♦ Deep Sleep, 8 kB RAM retention: 300 nA
♦ Audio Streaming at 7 kHz audio BW: 1.8 mA RX, 1.8 mA TX
• Current Consumption (3 V VBAT):
♦ Deep Sleep, IO wake−up: 25 nA
♦ Deep Sleep, 8 kB RAM retention: 100 nA
♦ Audio Streaming at 7 kHz audio BW: 0.9 mA RX, 0.9 mA TX
• 384 kB of flash memory
• Highly−integrated System−on−Chip (SoC)
• Supports FOTA (Firmware Over−The−Air) updates
• ARM Cortex−M3 Processor: A 32−bit core forreal−time applications, specifically developed to enablehigh−performance low−cost platforms for a broad rangeof low−power applications.
• LPDSP32: A 32−bit Dual Harvard DSP core thatefficiently supports audio codecs required for wirelessaudio communication. Various codecs are available tocustomers through libraries that are included inRSL10’s development tools.
• Radio frequency Front−End: Based on a 2.4 GHz RFtransceiver, the RFFE implements the physical layer ofthe Bluetooth low energy technology standard and other
proprietary or custom protocols.
• Protocol Baseband Hardware: Bluetooth 5 certifiedand includes support for a 2 Mbps RF link and customprotocol options. The RSL10 baseband stack issupplemented by support structures that enableimplementation of ON Semiconductor and customerdesigned custom protocols.
• Highly−Integrated SoC: The dual−core architecture iscomplemented by high−efficiency power managementunits, oscillators, flash and RAM memories, a DMA
controller, along with a full complement of peripheralsand interfaces.
• Deep Sleep Mode: RSL10 can be put into a DeepSleep Mode when no operations are required. VariousDeep Sleep Mode configurations are available,including:
♦ “IO wake−up” configuration. The powerconsumption in deep sleep mode is 50 nA (1.25 VVBAT).
♦ Embedded 32 kHz oscillator running with interruptsfrom timer or external pin. The total current drain is90 nA (1.25 V VBAT).
♦ As above with 8 kB RAM data retention. The totalcurrent drain is 300 nA (1.25 V VBAT).
♦ With the exception of IO wake up onlyconfiguration, the on−chip buck converter can alsobe enabled to reduce current consumption in DeepSleep Mode (at higher VBAT voltages).
• Standby Mode: Can be used to reduce the averagepower consumption for off−duty cycle operation,ranging typically from a few ms to a few hundreds ofms.The typical chip power consumption is 30 _A inStandby Mode.
• Multi−Protocol Support: Using the flexibilityprovided by LPDSP32, the ARM Cortex−M3 processor,and the RF front−end; proprietary protocols and othercustom protocols are supported.
• Flexible Supply Voltage: RSL10 integrates high−efficiency power regulators and has a VBAT range of1.1 to 3.3 V.
• Highly Configurable Interfaces: I2C, UART, two SPIinterfaces, PCM interface, multiple GPIOs. It alsosupports a digital microphone interface and an outputdriver.
• The Asynchronous Sample Rate Converter (ASRC)Block and Audio Sink Clock Blocks Provides a meansof synchronizing the audio sample rate between anaudio source and an audio sink. The audio sink clockalso provides a high accuracy mechanism to measure aninput clock used for the RTC or protocol timing.
• Flexible Clocking Scheme: RSL10 must be clockedfrom the XTAL/PLL of the radio front−end at 48 MHzwhen transmitting or receiving RF traffic. When RSL10is not transmitting/receiving RF traffic, it can run offthe 48 MHz XTAL, the internal RC oscillators, the32 kHz oscillator, or an external clock. A lowfrequency RTC clock at 32 kHz can also be used inDeep Sleep Mode. It can be sourced from either theinternal XTAL, the RC oscillator, or a digital input pad.
• Diverse Memory Architecture: 76 kB of SRAMprogram memory and 88 kB of SRAM data memoryare available. A total of 384 kB of flash is available tostore the Bluetooth stack and other applications. TheARM Cortex−M3 processor can execute from SRAMand/or flash.
• IP Protection Feature: Ensures that the customer’sflash contents cannot be copied by a third party. Itprevents any core or memory from being accessedexternally after the chip has booted.
• Ultra−Low Power Consumption ApplicationExamples:
♦ Audio Signal Streaming: IDD <1.8 mA @ VBAT1.25 V in Rx Mode for receiving, decoding andsending an 7 kHz bandwidth audio signal to the SPIinterface using a proprietary custom audio protocolfrom ON Semiconductor.
♦ Low Duty Cycle Advertising: IDD 1.3 _A foradvertising at all three channels at 5 second intervals@ VBAT 3 V, DCDC converter enabled.
• Development Tools: Includes development hardwareand the standard Eclipse−based and other IntegratedDevelopment Environment (IDE) components for theARM Cortex−M3 processor. The LPDSP32 code can bedeveloped using the Synopsys development tools,which are available by request.
• RoHS Compliant device
