Description

The Cirrus Logic CS22210 Wireless Network Controller enables high speed, 11 Mbps digital wireless data connectivity for wireless data connectivity for PCI, mobile, embedded systems and other cost sensitive applications.

Features

Embedded ARM Core and System Support Logic

? High performance ARM7TDMI RISC processor core at 77MHz

? 4KB integrated, one-way set associative, unified, write through cache

? Individual interrupt for each functional block

? Two 23-bit programmable (periodic or one-shot) general purpose timers

? 8 Dword (32-bits) memory write and read buffers for high system performance

? Abort cycle detection and reporting for debugging

? ARM performance monitoring function for system fine-tuning

? Programmable performance improvement logic based on system configuration

? Flexible independent DMA engines for PCI, USB and digital radio functional units

Enhanced Memory Controller Unit

? Programmable memory controller unit supporting SDRAM /async SRAM/boot ROM interface

? 16-bit data bus with 12-bit address supporting up to 4MB at up to 103MHz SDRAM

? 8-bit data bus with addressing support up to 1MB of boot ROM/Flash

? Programmable SDRAM timing and size parameters such as CAS latencies and number of banks columns and rows

FEC codec

? High performance Reed-Solomon coding for error correction (255:239 block coding)

? Reduces symbol error probability of a typical 10e-3 error rate environment to 10e-9

? Programmable rate FEC engine to optimize channel efficiency

? Low latency, fully pipelined hardware encoding and decoding. Support byte wise single cycle throughput up to 77MHz, with a sustain rate of 77MBps.

? Double buffering (64 Dword read/write buffer) to enhance system performance

? On the fly configuration of encoder and decoder

Digital Wireless Radio MAC

? Standard interface to 802.11b radio baseband transceiver

? 11Mbps data rate

? 32 Dword transmit/receive FIFO

? Supports clear channel assessment (CCA)

Power Management

? Host (PCI or USB) ACPI compliant

? Remote USB host wakeup

? Supports variable rate radio transmit, receive and standby radio power modes through two DACs

Clock and PLL Interface

? Single 44MHz crystal oscillator reference clock for PCI version; 48MHz reference clock required in USB option

? Internal PLL to generate internal and on board clocks

PCI Controller Interface

? 33MHz 5V/3.3V PCI 2.1 and PCI 2.2 compliant master/target 32-bit data interface

? ARM communication with PCI controller through simple mailbox scheme

? Generic PCI controller programming interface

? Flexible configuration programming via EEPROM

USB Controller Interface

? 12 Mbps USB 1.1 compliant device

? Supports 1 to 16 endpoints; endpoints can be bulk, isochronous or interrupt

? Variable endpoint buffer depths providing maximum flexibility for endpoint configurations

? Flexible configuration programming via EEPROM or firmware download

? Remote host wakeup

Chip Processing and Packaging

? 208 MQFP package and 0.18 um state of the art CMOS process

? 1.8 V core for low power consumption; 3.3V I/O and 5V tolerant
