Device Overview
The RC32336 device is a member of the IDT™ Interprise™ family of
integrated communications processors. It provides an effective solution
for small office/home office (SOHO) applications including gateways and
both single-band and dual-band wireless access points. Featuring a
MIPS compatible CPU core, the device also includes a memory
controller supporting SDRAM memory, a PCI interface featuring an onchip
arbiter to support up to three external devices, a PCMCIA interface
that supports a single I/O device, and two integrated on-chip 10/100
Ethernet MACs to enable WAN and LAN connectivity.
The key features of the RC32336 enable SOHO applications at
unmatched price/performance points. The MIPS-compatible CPU core
has the required bandwidth to enable a WAP application with the latest
wireless security protocols, WPA and 802.11i, which include the enterprise-
level user authentication schemes 802.1x and Extensible Authentication
Protocol (EAP). The ability to connect and support the bandwidth
requirements of one or two WLAN modules is made possible by the high
bandwidth PCI and PCMCIA interfaces. Also, the device has been architected
to provide high speed LAN to WAN routing bandwidth through the
Ethernet MACs while simultaneously driving data through the other onchip
interfaces.
