CYW43362
Single-Chip IEEE 802.11™
b/g/n MAC/Baseband/Radio
The Cypress CYW43362 single-chip device provides the highest level of integration for Interent of Things applications and handheld
wireless systems, featuring integrated IEEE 802.11™ b/g and IEEE 802.11n. It includes a 2.4 GHz WLAN CMOS power amplifier
(PA) that meets the output power requirements of most handheld systems. An optional external low-noise amplifier (LNA) and exter-
nal PA are also supported.
Along with the integrated power amplifier, the CYW43362 also includes integrated transmit and receive baluns, further reducing the
overall solution cost.
Host interface options include SDIO v2.0 that can operate in 4b or 1b modes.
Utilizing advanced design techniques and process technology to reduce active and idle power, the CYW43362 is designed to
address the needs of highly mobile devices that require minimal power consumption and compact size. It includes a power manage-
ment unit that simplifies the system power topology and allows for operation directly from a rechargeable mobile platform battery
while maximizing battery life.
Features
Single-band 2.4 GHz IEEE 802.11 b/g/n
Integrated WLAN CMOS power amplifier with internal
power detector and closed-loop power control
Internal fractional-N PLL enables the use of a wide
range of reference clock frequencies
Supports IEEE 802.15.2 external 3-wire and 4-wire
coexistence schemes to optimize bandwidth utilization
with other co-located wireless technologies such as

coexistence interface.
Supports SDIO v2.0 (50 MHz, 4-bit and 1-bit)
Integrated ARM Cortex™-M3 CPU with on-chip mem-
ory enables running IEEE 802.11 firmware that can be
field-upgraded with future features.
Supports WMM®, WMM-PS, and Wi-Fi Voice Personal
(upgradable to Voice Enterprise in the future)
Security:
Hardware WAPI acceleration engine
AES and TKIP in hardware for faster data encryp-
tion and IEEE 802.11i compatibility
WPA™- and WPA2™- (Personal) support for pow-
erful encryption and authentication
Programmable dynamic power management
Supports battery voltage range from 2.3V to 4.8V sup-
plies with internal switching regulator
1 kbit One-Time Programmable (OTP) memory for
storing board parameters
69-bump WLBGA
(4.52 mm x 2.92 mm, 0.4 mm pitch)

CYW43362
Introduction
This document provides engineering design information for the CYW43362, a single chip with an integrated 2.4 GHz RF transceiver,
MAC, and baseband processor that fully supports the IEEE 802.11™ b/g/n standards.
The information provided is intended for hardware design engineers who will be incorporating the CYW43362 into their designs.
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.
