DATASHEET
This product datasheet contains a detailed description of the SX1235 performance and functionality. Please consult the
Semtech website for the latest updates or errata.
1. General Description
The SX1235 is a single-chip integrated transceiver circuit that is optimized for EN 300 220-1 category 1 receiver
applications. The fully integrated architecture of the transceiver is combined with an automated packet engine and top level
sequencer. In conjunction with a 64 byte FIFO these automate the entire process of packet transmission, reception and
acknowledgement without incurring the consumption penalty common to many transceivers that feature an on-chip MCUs.
Being easily configurable, it greatly simplifies system design and reduces external MCU workload to a minimum. The small
external BOM is limited to a quartz crystal frequency reference, passive decoupling, matching and filtering components.
SX1235 is intended for use as a high-performance, low-cost, FSK and OOK RF transceiver for robust, frequency agile,
half-duplex, bidirectional RF links. Where stable and constant RF performance is required over the full operating range of
the device down to 1.8 V the receiver and PA are fully regulated. For transmit intensive applications - a high efficiency PA
can be selected to optimize the current consumption.
The SX1235 features high receiver sensitivity and low receive current, equating to a high link budget, 143dB (-123dBm
sensitivity in conjunction with +20dBm Pout) and long battery life. The SX1235 complies with both ETSI and FCC
regulatory requirements and is available in a 5 x 5 mm QFN 24 lead package.
