SX1230 ADVANCED COMMUNICATIONS & SENSING DATASHEET SX1230 - Integrated Transmitter IC Narrow/wideband 315 MHz, 434 MHz 868 MHz and 915 MHz band Transmitter GENERAL DESCRIPTION APPLICATIONS The SX1230 is a fully integrated transmitter which can Remote Keyless Entry (RKE) operate in the 315, 434, 868 and 915 MHz licence free ISM bands. Remote Control / Security Systems The transmitter has two modes of operation, a conventional Voice and Data RF Communication Links MCU controlled mode and a stand-alone mode which Process and building / home control enables the SX1230 to download configuration and 2 Active RFID messages from an E PROM in response to a user input. Stand-alone mode makes the SX1230 ideal for miniaturized AMR / AMI Platforms or low cost remote keyless entry (RKE) applications. It also offers the unique advantage of narrow-band and wide-band KEY PRODUCT FEATURES communication in a range of modulation formats. +17 dBm to -18 dBm Programmable output power. The SX1230 offers high RF output power and channelized operation suited for the European (ETSI EN 300-220-1), Bit rates up to 600 kbits / sec. North American (FCC part 15.231, 15.247 and 15.249) and FSK, GFSK, MSK, GMSK and OOK modulation. Japanese (ARIB T-67) regulatory standards. Stand-alone mode: No need for a host MCU. ORDERING INFORMATION Consistent RF performance over a 1.8 to 3.7 V range. Low phase noise (-95 dBc/Hz at 50 kHz) with automated Part Number Temperature Range Qty. per Reel Package PLL calibration and fully integrated VCO and loop filter. SX1230I066TRT -40 C to +85 C 3000 MLPQ-24 (4x4mm) On chip RC timer for timer / wake-up applications. Low battery detection. Pb-free, Halogen free, RoHS/WEEE compliant product MLPQ-24 4x4mm Package - Operating Range -40 +85C 1 SX1230, Revision 4 December 2015 Page 1 www.semtech.com 2015 Semtech Corp. 1.
