Wireless LAN Module with Flash Memory
BP3599
Enable wireless LAN communication by
simply connecting to existing sets
Product Outline
The BP3599 takes the IEEE802.11b/g/n BP3591 wireless LAN module with built-in antenna and flash memory. In
addition, the antenna design is identical to the BP3591, eliminating the need for high-frequency circuitry, and
the BP3599 is pin-compatible with the BP3591, making replacement easy. The internal flash memory comes
pre-loaded with firmware including TCP/IP stack, and the module is already certified* for use in Japan and the US,
enabling implementation possible.
*Please inquire regarding applicable radio laws in other countries

Firmware, including the TCP/IP stack, is pre-loaded in the internal flash memory. Stations and
access points are written in Regions 1 and 2, respectively, making it easy to change operating
modes by switching the FLASH_SEL pin from High to Low and vice versa.

Applications
• Industrial equipment, sensor networks, home networks
• Wireless LAN routers and peripheral devices
• Smartphones and the like
• Systems that could not support wireless LAN due to insufficient MCU
• Systems that could not support wireless LAN due to costs
Support:http://micro.rohm.com/en/download_support/wireless_lan_system/
The firmware written in the flash memory includes protocols essential for wireless LAN
communication, such as WPA-PSK, WPA2-PSK, and WPS. In addition, the pre-loaded
TCP/IP stack enables both wireless LAN and network processing, making it easy to add IP
communication to sets that previously could not support wireless LAN due to insufficient
microcontroller processing capability or other restrictions.
