PRELIMINARY
CYW43364
Single-Chip IEEE 802.11 b/g/n MAC/
Baseband/Radio
The Cypress CYW43364 is a highly integrated single-chip solution and offers the lowest RBOM in the industry for Internet of Things
(IoT) and a wide range of other portable devices. The chip includes a 2.4 GHz WLAN IEEE 802.11 b/g/n MAC/baseband/radio. In
addition, it integrates a power amplifier (PA) that meets the output power requirements of most handheld systems, a low-noise amplifier
(LNA) for best-in-class receiver sensitivity, and an internal transmit/receive (iTR) RF switch, further reducing the overall solution cost
and printed circuit board area.
The WLAN host interface supports gSPI and SDIO v2.0 modes, providing a raw data transfer rate up to 200 Mbps when operating in
4-bit mode at a 50 MHz bus frequency.
Using advanced design techniques and process technology to reduce active and idle power, the CYW43364 is designed to address
the needs of highly mobile devices that require minimal power consumption and compact size. It includes a power management unit
that simplifies the system power topology while maximizing battery life.
Cypress Part Numbering Scheme
Cypress is converting the acquired IoT part numbers from Broadcom to the Cypress part numbering scheme. Due to this conversion,
there is no change in form, fit, or function as a result of offering the device with Cypress part number marking. The table provides
Cypress ordering part number that matches an existing IoT part number.
