Description
The EM9201 is a low-voltage 2.4GHz transceiver IC with
built-in link-layer logic permitting proprietary wireless links
in the 2.400 … 2.485 GHz ISM band. It has a radio core
with a low-IF architecture and GFSK modulation scheme
being compliant with the emerging Bluetooth low energy
technology standard.
Control of the link-layer logic is possible though the SPI
interface using an external host-controller. An FPGA bridge
is included in the circuit such that with an external FPGA
any protocol compatible with the RF characteristics can
also be emulated through the SPI port of the EM9201.
The EM9201 can be operated from a single 1.5V battery by
making use of the on-chip step-up (boost) DC/DC
converter. This converter is designed to support an extra
load such as a low-power microcontroller (host) or sensor
interface circuit with a dedicated application profile.
The EM9201 can also operate without the DC/DC
converter, when supplied from a 3 V battery or any other
source such as an external LDO regulator. No external coil
is needed then.
These two possibilities are programmable by a metal mask
option:
V1: with DC/DC converter for 1.5V battery
V2: w/o DC/DC converter for any voltages 1.9 – 3.6V
