ZWIR4501 Data Sheet and User Manual (v 1.1)
Single-Chip 900 MHz RF Transceiver with Integrated Thin HW-MAC
IEEE 802.15.4 Compliant / ZigBeeTM Ready
Description
Applications
The ZWIR4501 is a fully integrated system-on-chip
CMOS transceiver providing license-free multichannel 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.
