JM20335
Hi-Speed USB to PATA Bridge
JMicron/JM20335
Description
The JM20335 is single chip solution to bridge between Hi-Speed USB and ATA/ATAPI-based
mass storage device. It provides the capability to translate USB mass storage commands to ATA/ATAPI
communication protocol. The USB adheres the Mass Storage Class Bulk-Only Transport Specification,
and supports dual LUN operation, which could connect to two ATA/ATAPI devices. The embedded
command parser supports both ATA and ATAPI command set with LBA48 addressing capability.
This chip is designed by 0.18um CMOS technology with 64 LQFP package
.
