Sunrise Micro Devices Announces Low-Power Bluetooth® Smart Radio Core to Get Billions of IoT Sensors Talking
DEERFIELD BEACH, Fla. --(Business Wire)--
Wireless intellectual property (IP) company Sunrise Micro Devices Inc.
(SMD), is announcing CORDIO™ BT4 radio core, the first radio core
offering from its CORDIO family of sub-volt wireless products. This
low-power radio core is targeted at the billions of battery or energy
harvester-powered Internet of Things (IoT) sensors forecast to be
shipped in the coming years.
Massive scale IoT network nodes require three core elements: a sensor
for measurement, processing power and connectivity to communicate the
processed data. SMD's offering provides the connectivity piece - CORDIO
BT4 radio IP incorporates Bluetooth Core Specification Version 4.1 with
a Low Energy Core Configuration that is suitable for applications where
sensors are expected to operate for years without human intervention.
"CORDIO BT4 is a Bluetooth Smart radio building block that is truly
low-power and is straightforward to incorporate into a chip design,"
said Dr. Fred Martin, president and CEO at SMD. "This offering is
aligned with our goal of making wireless connectivity practical for the
IoT, by making truly low-voltage, low-power devices a reality."
"Bluetooth Smart device shipments are projected to grow to over three
billion by 2018," said Suke Jawanda, chief marketing officer for the
Bluetooth SIG. "While its power-efficiency makes it perfect for devices
needing to run off a tiny battery for long periods of time, the magic of
Bluetooth Smart is its ability to work with an application on the
smartphone or tablet consumers already own. It's exciting to see Sunrise
join other leading suppliers go all-in for Bluetooth Smart and help
power the next wave of Bluetooth innovation."
This radio core solution is a fully integrated platform that includes a
transceiver, baseband and link layer (LL) subsystem for separate and
independent execution of the link layer and the host controller
interface (HCI). The integrated LL subsystem provides an energy
efficient, timing-independent interface to the host processor, enabling
easy imlementation of the stack and application layers. In addition,
the subsystem allows for efficient sleep and wake-up of the host
processor leading to lower system-wide power consumption.
CORDIO BT4 is the only native sub-1 Volt platform in the market today -
all the core circuits within the SMD radio are designed at 950mV
(nominal). It has integrated power management for 1V or 3V battery
applications. Due to the lower operating point for the internal
circuits, the total power consumed during TX and RX is only 6mW (6mA at
1V) and the radio has a RX sensitivity of -94dBm. The market needs low
voltage technologies that allow node devices to operate longer by
drawing minimum current and utilizing otherwise unused battery energy.
By incorporating the CORDIO BT4 sub-1 volt radio core solution, battery
life of IoT devices can be extended by as much as 60 percent compared to
CORDIO BT4 is optimized for the TSMC 55nm process and is delivered as a
Hard Macro. In addition to reducing implementation time and facilitating
ease of integration into SoCs, a Hard Marco implementation offers
distinct advantages in the Bluetooth qualification process. SMD radio
core will be a Bluetooth qualified controller sub-system (with a unique
QDID) to ease Bluetooth listing of OEM products.
With a single antenna pin, integrated RX/TX switch and integrated
capacitive DC-DC down-converter, the BT4 IP is designed with low cost
and small size in mind and can be implemented with just nine external
components. This will enable customers to offer smaller, less expensive
and more reliable devices and position themselves well for adoption in
high growth areas such as wearables, sports and fitness.
