DOCUMENT: 3650H-02DSR JUNE 17, 2008

OVERVIEW

SiliconDrive combines all the high

performance, high reliability, and multiyear

lifecycle benefits of the standard

SiliconDrive with a comprehensive suite of

patented and patent-pending technologies

that provide multiple security options to

safeguard application data and software IP

in embedded systems.

Applications requiring advanced levels of

security such as data recorders, wearable

and field computers, medical monitoring

and diagnostic equipment, POS systems,

and voting machines are able to activate

security options to protect application data

and software IP from theft, falling into the

wrong hands from deployments in high-

risk areas, corruption, and accidental or

malicious overwrites.

PowerArmor prevents data corruption and

loss from power disturbances by

integrating patented technology into every

SiliconDrive.

SiSMART acts as an early warning system

to eliminate unscheduled downtime by

constantly monitoring and reporting the

exact amount of remaining storage system

useful life.

SiSecure is a comprehensive suite of user-

selectable security technologies that

solves the critical need for robust storage

security for embedded systems

applications that have a small footprint and

low-power requirement.

PAGE 47
ATA COMMAND BLOCK AND SET DESCRIPTION SSD-HXXX(I)-3650 DATA SHEET Idle — 97h, E3h When issued by the host, the device’s internal controller sets the BSY bit, enters the Idle mode, clears the BSY bit, and generates an interrupt. If the sector count is non-zero, it is interpreted as a timer count with each count being 5ms, and the automatic power-down mode is enabled. If the sector count is zero, the automatic power-down mode is disabled.
PAGE 48
SSD-HXXX(I)-3650 DATA SHEET ATA COMMAND BLOCK AND SET DESCRIPTION Idle Immediate — 95h, E1h When issued by the host, the device’s internal controller sets the BSY bit, enters Idle Mode, clears the BSY bit, and issues an interrupt.

PAGE 56
SSD-HXXX(I)-3650 DATA SHEET ATA COMMAND BLOCK AND SET DESCRIPTION Read Verify Sector(s) — 40h, 41h The Read Verify Sector(s) command operates similarly to the Read Sector(s) command, with the exception that is does not set the DRQ bit and does not transfer data to the host. When the requested sectors are verified, the onboard controller clears the BSY bit and issues an interrupt.
PAGE 57
ATA COMMAND BLOCK AND SET DESCRIPTION SSD-HXXX(I)-3650 DATA SHEET Seek — 7Xh The Seek command seeks and picks up the head to the tracks specified in the task file. When the command is issued, the solid-state memory chips do not need to be formatted. After an appropriate amount of time, the DSC bit is set.

PAGE 60
SSD-HXXX(I)-3650 DATA SHEET ATA COMMAND BLOCK AND SET DESCRIPTION Set Sleep Mode — 99h, E6h The Set Sleep Mode command allows the host to set the device in sleep mode. When the onboard controller transitions to sleep mode, it clears the BSY bit and issues an interrupt. The device interface then becomes inactive. Sleep mode can be exited by issuing either a hardware or software reset.
PAGE 61
ATA COMMAND BLOCK AND SET DESCRIPTION SSD-HXXX(I)-3650 DATA SHEET Standby — 96h, E2h When the Standby command is issued by the host, it transitions the device into standby mode. If the Sector Count register is set to a value other than 0h, the Auto Powerdown function is enabled and the device returns to Idle mode.
PAGE 62
SSD-HXXX(I)-3650 DATA SHEET ATA COMMAND BLOCK AND SET DESCRIPTION Standby Immediate — 94h, E0h When the Standby Immediate command is issued by the host, it transitions the device into standby mode.
PAGE 63

PAGE 64
SSD-HXXX(I)-3650 DATA SHEET ATA COMMAND BLOCK AND SET DESCRIPTION Write DMA — CAh The Write DMA command allows the host to write data using the DMA transfer protocol. Note: This function does not apply to SiliconDrives that have DMA disabled.
PAGE 65
ATA COMMAND BLOCK AND SET DESCRIPTION SSD-HXXX(I)-3650 DATA SHEET Write Multiple — C5h The Write Multiple command operates in the same manner as the Write Sector command. When issued, the device sets the BSY bit within 400ns and generates an interrupt at the completion of a transferred block of sectors. The DRQ bit is set at the beginning of a block transfer.
PAGE 66
SSD-HXXX(I)-3650 DATA SHEET ATA COMMAND BLOCK AND SET DESCRIPTION Write Sector(s) — 30h, 31h The Write Sector(s) command writes from 1 to 256 sectors as specified in the Sector Count register. A sector count of 0 requests 256 sectors. When issued, the device sets the BSY bit within 400ns and generates an interrupt at the completion of a transferred block of sectors. The DRQ bit is set at the beginning of a block transfer.
PAGE 67
ATA COMMAND BLOCK AND SET DESCRIPTION SSD-HXXX(I)-3650 DATA SHEET Write Long Sector(s) — 32h, 33h The Write Long Sector(s) command operates in the same manner as the Write Sector command — when issued, the device sets the BSY bit within 400ns and generates an interrupt at the completion of a transferred block of sectors. The DRQ bit is set at the beginning of a block transfer.
