Holtek is delighted to announce the release of its new low current bidirectional wireless FSK/GFSK transceiver IC, the BC3602. The device, which includes an integrated high precision, low power oscillator for WOT (Wake-on-TX) and WOR (Wake-on-RX) functions, is suitable for battery or IoT applications that require low power consumption, such as smart homes, intelligent security products, remote meter reading, industrial/agricultural controllers and many other wireless bidirectional communication products.
This device operates in the 315/ 433/ 470/ 868/ 915 MHz license-free ISM bands and includes a fully integrated high power programmable amplifier, a frequency synthesizer and a digital demodulation function, etc., greatly simplifying the overall circuit design. With regards to standards, the device RF characteristics are compliant with ETSI/FCC specifications. The device has an operating voltage ranging from 1.9 V to 3.6 V and a programmable transmitting power up to +13 dBm. Its receiving sensitivity can be up to –120 dBm at a data rate of 2 kbps. It has a receiving current as low as 4.2 mA at 433 MHz and a transmission rate of up to 250 kbps. The device also includes an ATR (Auto-Transmit-Receive) function.
The BC3602 includes an SPI control interface and meets with the industrial specification operating temperature of –40 °C…85 °C. It is supplied in a small 24-pin QFN (3 mm × 3 mm) package type which will meet the requirements of low profile wireless product and module designs.
