ZWIR4501 - IEEE 802.15.4 SubG Transceiver
Brief Description
The ZWIR4501 is a fully integrated system-on-chip CMOS transceiver providing license-free multi-channel operation in the 868.3 MHz (EU) and 902 MHz to 928 MHz (North America) ISM bands. This low-power RF transceiver is optimized for data rates up to 40 kbit/s and incorporates direct sequence spread spectrum technology (DSSS) to ensure reliable data transfer in hostile RF environments. The high level of integration, shown below, includes a thin Media Access Control (MAC) layer, resulting in a minimum of external components and lower application costs.
