wider supply range with a single power supply
• Over 75dB RX of gain in programmable gain steps
• Integrated SPI and UART for ACI interfaces
• Includes Sleep and Power Down modes for low
power consumption
• Embedded patch memory to reduce system
development effort and cost – BC7602 only
• Package types:
♦♦ _{BC7601: 32-pin QFN – 4mmx4mm}
♦♦ _{BC7602: 46-pin QFN – 6.5mmx4.5mm}
Applications
• Health care products
• Smart home appliances
• Beacons
General Description
The BC7601/BC7602 devices are fully-integrated,
single-chip Bluetooth Low Energy, BLE, controllers.
The devices are specially designed to act as BLE
slave controllers in accordance with the Bluetooth
specification v4.1.
The devices can be controlled by any external
microcontroller through the Application Controller
Interface, ACI, which is designed to allow the devices
to easily communicate with external circuitry. The
UART and SPI interfaces are available as the ACI
transport layers.
Additionally, during intervals where there is no active
BLE RF connection, the devices will enter a Sleep
Mode thus further reducing power consumption.
In general practice, the BC7601/BC7602 devices
will be required to download a patch code for full
BLE optimisation. For convenience and system cost
reduction, the BC7602 device already supports an
internal patch code and so does not need to patch
from the external microcontroller.
