TRC102

400 - 1000MHz RF Transceiver

Unspecified 

Low Battery Detector

The integrated low battery detector monitors the voltage supply against a preprogrammed value and

generates an interrupt when the supply voltage falls below the programmed value. The detector circuit

has 50mV of hysteresis built in.

SPI Interface

The TRC102 is equipped with a standard SPI bus that is compatible to almost all SPI devices. All

functions and status of the chip are accessible through the SPI bus. Typical SPI devices are configured

for byte write operations. The TRC102 uses word writes so the nCS pin(3) should be pulled low for 16

bits.
