BLE112 Bluetooth® low energy single mode module

DESCRIPTION

BLE112, Bluetooth low energy single mode
module is a single mode device targeted for
low power sensors and accessories.

BLE112 offers all Bluetooth low energy
features: radio, stack, profiles and application
space for customer applications, so no
external processor is needed. The module also
provides flexible hardware interfaces to
connect sensors, simple user interfaces or
even displays directly to the module.

BLE112 can be powered directly with a
standard 3V coin cell batteries or pair of AAA
batteries. In lowest power sleep mode it
consumes only 400nA and will wake up in few
hundred microseconds.

APPLICATIONS:

 Heart rate sensors
 Pedometers
 Watches
 Blood pressure and glucose meters

KEY FEATURES:

 Bluetooth v.4.0, single mode compliant

o Supports master and slave

modes

o 4+ simultaneous connection

in master mode

 Integrated Bluetooth low energy stack

o GAP, GATT, L2CAP, SMP
o Bluetooth low energy profiles

 Radio performance

o TX power: +3dBm to -23dBm
o RX sensitivity: -87dBm to -

93dBm

 Ultra low current consumption

o Transmit: 27mA (0dBm)
o Sleep mode 3: 0.4uA

 Programmable 8051 processor for

embedding full applications

 Weight scales
 Key fobs
 Households sensors and collector

devices

 Security tags
 Wireless keys (keyless go)
 Proximity sensors
 HID keyboards and mice
 Indoor GPS broadcasting devices

 Bluetooth end product, CE, FCC and

IC and Telec qualified
