490个 EM MICROELECTRONIC EM9203超低功耗高性能2.4GHz GFSK无线收发芯片 EM9203V02LF28D+ 1.9V-3.6V

The EM9203 is a 1Mbps or 2Mbps low-power, low-voltage,
completely-integrated 2.4GHz ISM band RF transceiver ideal for
battery operated wireless applications such as wireless sensors and
control, audio streaming, human interface devices, and security
networks.
The EM9203’s built-in baseband processor (with Link Layer) permits
implementation of optimized proprietary wireless protocol links in the
license-free 2.4000GHz to 2.4835GHz ISM band. It includes a low-IF
receiver architecture and uses GFSK modulation compliant with the
emerging Bluetooth Low Energy (4.0) standard. An industry-standard
SPI interface provides for simple control of the baseband using an
external host controller.
The EM9203 Version 11 features an integrated step-up (boost) DC/
DC converter that allows operation with supply voltages as low as
0.8V with an external coil. This converter is designed to support
an additional load such as a low-power microcontroller (host) and
interface circuits with a dedicated application profile. The EM9203
Version 12 can be supplied by a 3V battery or other voltage source.
Available chip versions:
I Version 11: with DC/DC converter for use with 1.5V battery (down
to 0.8V)
I Version 12: without DC/DC converter for use with any voltage from
1.9V to 3.6V
