The SPIRIT1 is a very low-power RF transceiver, intended for RF wireless applications in the sub-1 GHz band. It is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915 MHz, but can also be programmed to operate at other additional frequencies in the 300-348 MHz, 387-470 MHz, and 779-956 MHz bands. The air data rate is programmable from 1 to 500 kbps, and the SPIRIT1 can be used in systems with channel spacing of 12.5/25 kHz, complying with the EN 300 220 standard. It uses a very small number of discrete external components and integrates a configurable baseband modem, which supports data management, modulation, and demodulation. The data management handles the data in the proprietary fully programmable packet format also allows the M-Bus standard compliance format (all performance classes).

However, the SPIRIT1 can perform cyclic redundancy checks on the data as well as FEC encoding/decoding on the packets. The SPIRIT1 provides an optional automatic acknowledgement, retransmission, and timeout protocol engine in order to reduce overall system costs by handling all the high-speed link layer operations.

Moreover, the SPIRIT1 supports an embedded CSMA/CA engine. An AES 128-bit encryption co-processor is available for secure data transfer. The SPIRIT1 fully supports antenna diversity with an integrated antenna switching control algorithm. The SPIRIT1 supports different modulation schemes: 2-FSK, GFSK, OOK, ASK, and MSK. Transmitted/received data bytes are buffered in two different three-level FIFOs (TX FIFO and RX FIFO), accessible via the SPI interface for host processing.

spirit1是一个非常低功耗RF收发器，用于1 GHz频段的射频无线应用。它被设计为工作在无需许可的ISM和SRD频带在169，315，433，868，和915兆赫，但也可以被编程为在300-348 MHz频率运行，其他387-470兆赫，和779-956兆赫波段。空气数据率可从1到500 kbps，而spirit1可用于与12.5/25千赫信道间隔的系统，符合EN 300标准220。它使用了一个非常小的数量的离散的外部元件，并集成了一个可配置的基带调制解调器，它支持数据管理，调制和解调。数据管理处理数据的专有的完全可编程的数据包格式还允许M-Bus标准格式（所有性能等级）。

然而，这spirit1可以执行循环冗余校验的数据以及FEC编码/解码的数据包。的spirit1提供一个可选的自动确认、重传超时协议引擎，并以处理所有的高速链路层操作，降低整体系统成本。

此外，该spirit1支持嵌入式CSMA/CA机。AES 128位加密协处理器可用于安全的数据传输。的spirit1完全支持一个集成天线开关控制算法的天线分集。spirit1支持不同的调制方案的性能，GFSK，OOK，问，和MSK。发送/接收的数据字节缓冲在两个不同的三级FIFO（TX FIFO和Rx FIFO），可通过SPI接口的主机处理。
