The Chili2 SMARTRange™ module family are fully-featured Thread-based wireless solution for IEEE 802.15.4 communications in the 2.4GHz band. The Chili2 pairs the Cascoda CA-8211 transceiver modem with an ARM® Cortex®-M23 TrustZone® microcontroller. The Chili2 module provides developers with system design advantages:
- Best-in-class RF performance with -105dBm receive sensitivity, +9 dBm transmit power and a +114 dB link budget:
Allowing whole-house coverage in any market on the planet, with no need for a power amplifier.
- World-class energy consumption, in all modes
- Highly secure ARM Cortex-M23 TrustZone architecture, running up to 64MHz
- Highly reliable and scalable IP-based mesh network using Thread
Secure by Design
The most advanced security features available, allowing developers to design robust products that comply with upcoming security legislation:
- Secure boot:
Cryptographic checks are added to each stage of the secure boot process, to assure the integrity of software images executed, thus preventing unauthorized software from running.
- True Random Number Generator (TRNG):
The TRNG enables the generation of a truly random bit stream, required for device cryptography.
- Cryptographic accelerator:
Protection for communication protocol keys, providing AES, SHA and Elliptic Curve cryptography.
- Memory, operation and tamper protection:
Protection for the device in operation with hardware separation between system and application code.
Support for Real Time Operating Systems (RTOS)
Support for the open-source FreeRTOS operating system out of the box, easing application development and the adoption of secure TrustZone features.
A production and a development platform
The Chili2D is a double-sided stand-alone module, intended as a development platform. It features a voltage regulator, a Li/Li-Po battery charger, a micro-USB socket and a 10-pin 0.05″ ARM-JTAG connector. Power can be provided through USB, 5V or 3V headers, the ARM-JTAG connector, a rechargeable Li/Li-Po battery, a non-rechargeable battery or a variety of energy-harvesting sources.
The Chili2S is a single-sided postage-stamp module, intended as a production platform. This is designed to be soldered to an application board, which will supply power and interfacing.
The Chili2S module is a highly-integrated postage-stamp module for Thread® / IEEE 802.15.4 low-power wireless personal area network (WPAN) applications.
The Chili2D module is a highly-integrated USB dongle module for developing Thread® / IEEE 802.15.4 low-power wireless personal area network (WPAN) applications.
