wisesun WS4460

WS4460 is a true single-die, next-generation OOK transmitter SOC with an integrated encoder, fully compatible with 1527-encoded products. It supports the commonly used 315 MHz/433.92 MHz frequencies, features 4 independent keys and 6 combination keys, delivers high-power output for extended communication range, and offers a zero-power standby mode for longer battery life. In addition to the 1527-compatible format with 20-bit address fields, the chip also supports proprietary modes for enhanced product security. It supports 24/28-bit proprietary address formats, providing up to 268 million unique address combinations. Data frame and checksum support eliminates false device triggering caused by over-the-air interference. When paired with WS480/WS490 series receiver ICs, this solution effectively meets users' wireless control needs for low cost, low power consumption, and high performance.
