Atmel SmartConnect SAM B11
BLE 4.1 Wireless MCU
The Atmel® SmartConnect SAM B11 is an ultra-low-power Bluetooth® SMART (BLE 4.1) system on a chip (SoC)
integrated with an Atmel® | SMART microcontroller (MCU), transceiver, modem, MAC, PA, TR switch, and power man-
agement unit (PMU). It is a standalone applications processor with 256KB of Flash memory and with embedded BLE
connectivity.
The qualified Bluetooth Smart protocol stack is stored in dedicated ROM and includes L2CAP service layer protocol, securi-
ty manager, attribute protocol (ATT), generic attribute profile (GATT) and the generic access profile (GAP). Additionally,
application profiles such as Proximity, Thermometer, Heart Rate, Blood Pressure, and many others are supported and
included in the protocol stack.
The SAM B11 provides a cost-effective solution for
many Bluetooth Smart based applications by integrating
the Bluetooth Low Energy Radio and Baseband with
an ARM® Cortex® M0-based microcontroller. The need
for very few external components minimizes the total
system solution cost.
Accelerating RF Design
To help accelerate design development, Atmel offers the
SAM B11 as a single-chip module for fast integration,
and on an Xplained Pro evaluation board for fast and easy
application development within Atmel Studio.
Power Architecture and Consumption
The SAM B11 uses an innovative radio and DSP
architecture that delivers extremely low power
consumption along with high performance.
The SAM B11 has the lowest power consumption
available in the market.
• TX peak current: < 3mA @ 3.6V, 0dBm pout
• RX peak current: < 4mA @ 3.6V
• Sleep current: < 1uA with 8KB RAM retention
and RTC
• Advertise: > 4-year battery life with CR2032 coin cell
battery when advertising every 1-second as a beacon
SAM B11 SoC Target Applications
• Wearable with health and fitness sensors
• Smart appliances
• Security and proximity tags
• Home automation
• Smartphone accessories
• HID keyboards, mice and remote controls
