Chili2S Module Datasheet

Rev. 0.6, September 2019

GENERAL DESCRIPTION

The Chili2S module is a fully-featured Thread-certified wireless

module solution for IEEE 802.15.4 communications in the

2.4GHz band. It pairs the Cascoda CA-8211 SMARTRange™

transceiver modem with the Nuvoton M2351 Cortex

-M23

TrustZone

microcontroller.

With industry leading power consumption and sensitivity

performance, it delivers unparalleled range without external

amplifier components, thus providing whole-house connectivity

in any market on the planet.

BENEFITS

Equipment cost: Increased range removes the need for

external power amplifiers, thereby reducing component BOM.

Installation cost: Greater datalink reliability lessens the need

for skilled installers, and the consumer can self-install.

Maintenance cost: Lower power consumption means that

batteries last longer, thereby minimising maintenance cost.

Development time: Use of pre-certified module minimises

product development time.

APPLICATIONS

● Home and building automation

● Consumer electronics

● Lighting systems

● Heating, ventilation & air-conditioning systems (HVAC)

● Smart grid (AMI/AMR)

● Asset tracking (active RFID)

● Industrial control and monitoring

● Assisted living & telecare

Any antenna of the same type, with similar in-band and out-of-band characteristics and with the same or less gain, can be used without reassessment. In case of using an antenna of a different type and/or higher gain, reassessment and notification to the particular certification authority is required. 5.
