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是一個非常低功耗RF收發(fā)器，用于1 GHz頻段的射頻無線應用。它被設計為工作在無需許可的ISM和SRD頻帶在169，315，433，868，和915兆赫，但也可以被編程為在300-348 MHz頻率運行，其他387-470兆赫，和779-956兆赫波段。空氣數(shù)據(jù)率可從1到500 kbps，而spirit1可用于與12.5/25千赫信道間隔的系統(tǒng)，符合EN 300標準220。它使用了一個非常小的數(shù)量的離散的外部元件，并集成了一個可配置的基帶調(diào)制解調(diào)器，它支持數(shù)據(jù)管理，調(diào)制和解調(diào)。數(shù)據(jù)管理處理數(shù)據(jù)的專有的完全可編程的數(shù)據(jù)包格式還允許M-Bus標準格式（所有性能等級）。

然而，這spirit1可以執(zhí)行循環(huán)冗余校驗的數(shù)據(jù)以及FEC編碼/解碼的數(shù)據(jù)包。的spirit1提供一個可選的自動確認、重傳超時協(xié)議引擎，并以處理所有的高速鏈路層操作，降低整體系統(tǒng)成本。

此外，該spirit1支持嵌入式CSMA/CA機。AES 128位加密協(xié)處理器可用于安全的數(shù)據(jù)傳輸。的spirit1完全支持一個集成天線開關控制算法的天線分集。spirit1支持不同的調(diào)制方案的性能，GFSK，OOK，問，和MSK。發(fā)送/接收的數(shù)據(jù)字節(jié)緩沖在兩個不同的三級FIFO（TX FIFO和Rx FIFO），可通過SPI接口的主機處理。
