![deRFsamR21E -23S00/-23S20 Datasheet 1. General description The deRFsamR21E is a 2.4GHz ZigBee 3.0 radio module series which integrates the SoC ATSAMR21E18 from Microchip / Atmel together with a 4 Mbit data flash on a tiny size of 21 mm x 13 mm. The microcontroller ATSAMR21E18 integrates a powerful and energy efficient 32-Bit ARM Cortex-M0+ core together with a 2.4 GHz ZigBee radio transceiver. The module comes with 16 I/O’s, 256 kbit internal program flash and 4 Mbit data flash for firmware updates over the air and data storage. For reliable assembly the module offers SMD solderable side contacts in 50 mil / 1.27 mm grid. The module offers ZigBee 3.0 support for smart devices. Two radio module variants are available: deRFsamR21E-23S00: integrated RF-design with chip antenna deRFsamR21E-23S20: coaxial u.FL-connector for external antenna applications as well as a RF-pad for custom RF-designs e.g. external frontend or antenna diversity deRFsamR21E-23S00 deRFsamR21E-23S20 2. Features ATSAMR21E18 Single-chip ARM Cortex-M0+ based 32-bit Microcontroller with Low Power 2.4 GHz Transceiver for IEEE 802.15.4 and ZigBee Applications with 256 KB Flash and 16 I/O’s - all accessible outside the module (four occupied by data flash) - Maximum operating frequency 48 MHz - 128-bit AES crypto engine - 32-bit MAC symbol counter - Temperature sensor - Automatic transmission modes 4 Mbit data flash for firmware updates over the air and data storage Ready-to-use RF design Radio module with a link budget of up to 103 dBm CE compliant according to RED 2014/53/EU and FCC certified Single 2.5 V - 3.6 V supply Industrial temperature range -40°C to 85°C 1.27 mm / 50 mil pin header with several alternative functions: - Analog input (12-bit, 350ksps Analog-to-Digital Converter) - PWM output - TWI (I2C up to 3.4MHz) - SPI - UART - USB - GPIO - SWD programming interface High precision 16 MHz crystal oscillator](https://usermanual.wiki/dresden-elektronik-ingenieurtechnik/23SXX/User-Guide-3575098-Page-1.png)
