IDTTM InterpriseTM Integrated  
Communications Processor  
RC32336  
MMU  
Device Overview  
16-entry TLB  
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 on-  
chip 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.  
Supports variable page sizes and enhanced write algo-  
rithm  
Supports variable number of locked entries  
8KB Instruction Cache  
2-way set associative  
LRU replacement algorithm  
4 word line size  
Sub-block ordering  
Word parity  
Per line cache locking  
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 enter-  
prise-level user authentication schemes 802.1x and Extensible Authenti-  
cation 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 archi-  
tected to provide high speed LAN to WAN routing bandwidth through the  
Ethernet MACs while simultaneously driving data through the other on-  
chip interfaces.  
2KB Data Cache  
2-way set associative  
LRU replacement algorithm  
4 word line size  
Sub-block ordering  
Byte parity  
Per line cache locking  
Can be programmed on a page basis to implement write-  
through no write allocate, write-through write allocate, or  
write-back algorithms  
Enhanced EJTAG and JTAG Interfaces  
Compatible with IEEE Std. 1149.1-1990
