1.0 INTRODUCTION The SA 14030 Controller consists of a micrprocessor based controller with on-board data separator logic and is able to control a maximum of four drives. The drives can be any combination of Shugart SA 1000 fixed disk drives. SA800 floppy disk drives. or SA850 floppy disk drives. The floppy disk track formats are compatible with IBM 10/20 track formats. The SA 14030 can be mounted on the SAl 000 drive. Commands are issued to the controller over a bidirectional bus connected to the host computer. The data separator/"serdes" logic serializes bytes and converts to FM/MFM data. and deserializes FM/MFM data into 8-bit bytes. Due to the microprogrammed approach utilized in the controller. limited diagnostic capabilities are implemented. This methodology increases fault isolation efficiency and reduces system down time. Error jetection and correction will tolerate media imperfections up to 4-bit burs't errors. :'-lOTE: This device utilizes neaative logic (i.e .. OV
= logical 1)
1.1 SA1403D CONTROLLER FeATURES OVERLAPPED SEEK
In multiple drive configurations the host can issue seeks to different drives without waiting for the fi rst drive to complete its seek.
AUTOMATIC SEEK AND VERIFY
A seek command is implied in every data transfer command (READ. WRITE CHECK. etc.). If the heads are not positioned over the correct cylinder. a seek is initiated and a cylinder verification is performed after the seek completes.
FAULT DETECTION
Three classes of fault detection are provided for fault diagnosis: 1) Disk related faults. 2) Controller related faults. 3) Host comma~d or 110 timing faults. Fault detection is available from the interface as a status message and is also visibly displayed on a row of status LED's on the controller PCB. .
AUTOMATIC HEAD AND CYLINDER SWITCHING
If during a multi-block data transfer the end of a track is reached. the controller automatically switches to the next track. If the end of a cylinder is reached. the controller issues a seek and resumes the transfer.
DATA ERROR SENSING AND CORRECTION
If a data error IS detected during a disk data transfer. the controller indicates whether or not it is correctable. If correctable, it can be automatically corrected. (This applies to the SAl 000 only. CRC error detection is used on floopy disc drives.)
LOGICAL TO PHYSICAL DRIVE CORRELATION
Logl~~. Unit Number (LUN's) are independent of physical port numbers. All accesses specify LUN's.
ON BOARD SECTOR BUFFER
A sector buffer is provided on the controller to eliminate the possibility of data overruns during a data transfer.
EFFICIENT HOST INTERFACE PROTOCOL
A bidirectional bus between the controller and host provides a simple. yet efficient communication path. In addition. a high level command set permits effective command initiation.
SECTOR INTERLEAVE
Sector interleaving is programmable with up to a 16 way interleave.
000 PARITY
The 8 data bits on the interface bus can have odd parity. Depending on user preference. parity can be disabled.
FIXED SECTOR SIZE
The sector size is fixed at 256 bytes of data for the SA 1000.

1.1.1 OPTIONAL FEATURES MICRO DIAGNOSTICS
A set of diagnostic PROM's are available to allow stand alone diagnostic testing of both drive and controller. Reference Appendix A.

2.2 POWER REQUIREMENTS Three power supply voltages are required for the SA 1400 series controllers. The maximum current reqUirements are as follows:
+ 5VDC :!: 5% at 4.6 Amps - 5VDC :!: 5% at 0.5 Amps + 24VDC :!: 10% at 0.1 Amps Power is applied to the SA1400 series controller via J10 which is a 6 pin AMP Mate-N-Lok conl1ector (PIN 1-380999..Q) mounted on the component side of the board. The recommended mating connector, P10, is an AMP PIN 1-480270-0 utilizing AMP pins PIN 60619-1. The J10 pins are labeled on the connector. Figure 1 shows the pin assignments.
