• Manufacturer Part Number: SX1233IMLTRT
• Description: RF Transceiver Extended Bands Japan-Korea
• Manufacturer: Semtech

Specifications of SX1233IMLTRT

• Transmitting Current: 95mA
• Data Rate: 600Kbps
• Rf Ic Case Style: QFN
• No. Of Pins: 24
• Supply Voltage Range: 1.8V To 3.6V
• Operating Temperature Range: -40°C To +85°C
• Receiving Current: 17mA

The response of the temperature sensor is -1°C / Lsb. A CMOS temperature sensor is not accurate by nature, therefore it
should be calibrated at ambient temperature for precise temperature readings.
It takes less than 100 microseconds for the SX1233 to evaluate the temperature (from setting TempMeasStart to 1 to
TempMeasRunning reset).
3.5.18. Timeout Function
The SX1233 includes a Timeout function, which allows it to automatically shut-down the receiver after a receive sequence
and therefore save energy.
This timeout interrupt can be used to warn the companion processor to shut down the receiver and return to a lower power
mode.

Timeout interrupt is generated TimeoutRxStart x 16 x Tbit after switching to RX mode if RssiThreshold flag does not
raise within this time frame
Timeout interrupt is generated TimeoutRssiThresh x 16 x Tbit after RssiThreshold flag has been raised.
Returns 150d (typ.)
