Description

The EM9201/02 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 EM9201/02.

The EM9201/02 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 EM9201/02 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.

EM9201: up to 1 Mb/s on air data rate

EM9202: up to 2 Mb/s on air data rate

Chip versions, programmable by metal mask option:
