FEATURES
•Arm Cortex−M3 Processor: A 32−bit core for
real−time applications, specifically developed to enable
high−performance low−cost platforms for a broad range
of low−power applications.
•LPDSP32: A 32−bit Dual Harvard DSP core that
efficiently supports intensive signal processing
applications. Various codecs are available to customers
through libraries that are included in RSL10’s
development tools.
•Radio Frequency Front−End: Based on a 2.4 GHz RF
transceiver, the RFFE implements the physical layer of
the Bluetooth low energy technology standard and other
proprietary or custom protocols.
•Protocol Baseband Hardware: Bluetooth 5 certified
and includes support for a 2 Mbps RF link and custom
protocol options. The RSL10 baseband stack is
supplemented by support structures that enable
implementation of ON Semiconductor and customer
designed custom protocols.
•Highly−Integrated SoC: The dual−core architecture is
complemented by high−efficiency power management
units, oscillators, flash and RAM memories, a DMA
controller, along with a full complement of peripherals
and interfaces.
•Deep Sleep Mode: RSL10 can be put into a Deep
Sleep Mode when no operations are required. Various
Deep Sleep Mode configurations are available,
including:
♦“IO wake−up” configuration. The power
consumption in deep sleep mode is 50 nA (1.25 V
VBAT).
♦Embedded 32 kHz oscillator running with interrupts
from timer or external pin. The total current drain is
90 nA (1.25 V VBAT).
♦As above with 8 kB RAM data retention. The total
current drain is 300 nA (1.25 V VBAT).
♦With the exception of IO wake up only
configuration, the on−chip buck converter can also
be enabled to reduce current consumption in Deep
Sleep Mode (at higher VBAT voltages).
•Standby Mode: Can be used to reduce the average
power consumption for off−duty cycle operation,
ranging typically from a few ms to a few hundreds of
ms. The typical chip power consumption is 30 mA in
Standby Mode.
•Multi−Protocol Support: Using the flexibility
provided by LPDSP32, the Arm Cortex−M3 processor,
and the RF front−end; proprietary protocols and other
custom protocols are supported.
•Flexible Supply Voltage: RSL10 integrates high−
efficiency power regulators and has a VBAT range of
1.1 to 3.3 V.
•Highly Configurable Interfaces: , UART, two SPI
interfaces, PCM interface, multiple GPIOs. It also
supports a digital microphone interface (DMIC) and an
output driver (OD).
•Flexible Clocking Scheme: RSL10 must be clocked
from the XTAL/PLL of the radio front−end at 48 MHz
when transmitting or receiving RF traffic. When RSL10
is not transmitting/receiving RF traffic, it can run off
the 48 MHz XTAL, the internal RC oscillators, the
32 kHz oscillator, or an external clock. A low
frequency RTC clock at 32 kHz can also be used in
Deep Sleep Mode. It can be sourced from either the
internal XTAL, the RC oscillator, or a digital input pad.
•Diverse Memory Architecture: 76 kB of SRAM
program memory and 88 kB of SRAM data memory
are available. A total of 384 kB of flash is available to
store the Bluetooth stack and other applications.
The Arm Cortex−M3 processor can execute from
SRAM and/or flash.
•IP Protection Feature: Ensures that the customer’s
flash contents cannot be copied by a third party. It
prevents any core or memory from being accessed
externally after the chip has booted.
•Ultra−Low Power Consumption Application
Examples:
♦Low Duty Cycle Advertising: IDD 1.1 mA for
advertising at all three channels at 5 second intervals
@ VBAT 3 V, DCDC converter enabled.
•RoHS Compliant Device
