b. Byte erase is performed in accordance with the waveforms and timing relationships shown on figures 5, 6, and 7 (in  
accordance with appropriate device type) and the conditions specified in table I.  
4.4.4 Read mode operation. The waveforms and timing relationships shown on figure 4 and the conditions specified in table I  
shall be applied when reading the device. Pattern verification utilizes the read mode.  
4.4.5 Software data protection. Device types 09-16 software data protection offers a method of preventing inadvertent writes  
(see figure 9). The instructions, waveforms, and timing relationships shown on figures 4, 5, 6, 7, 10, and 11, and the conditions  
specified in table I shall apply (see 3.10.2).  
4.4.5.1 Set software data protection. Device types 09-16 are placed in protected state by writing a series of instructions (see  
figure 10) to the device. Once protected, writing to the device may only be performed by executing the same sequence of  
instructions appended with either a byte write operation or page write operation. The waveforms and timing relationships shown  
on figures 5, 6, and 7 and the test conditions and limits specified in table I shall apply.  
4.4.5.2 Reset software data protection. Device types 09-16 protection feature is reset by writing a series of instructions (see  
figure 11) to the device. The waveforms and timing relationships shown on figures 5, 6, and 7 and the test conditions and limits  
specified in table I shall apply.  
5. PACKAGING  
5.1 Packaging requirements. The requirements for packaging shall be in accordance with MIL-PRF-38535, appendix A.  
6. NOTES  
6.1 Intended use. Microcircuits conforming to this drawing are intended for use for Government microcircuit applications  
(original equipment), design applications, and logistics purposes.  
6.2 Replaceability. Microcircuits covered by this drawing will replace the same generic device covered by a  
contractor-prepared specification or drawing.  
6.3 Configuration control of SMD's. All proposed changes to existing SMD's will be coordinated with the users of record for  
the individual documents. This coordination will be accomplished using DD Form 1692, Engineering Change Proposal.  
6.4 Record of users. Military and industrial users shall inform Defense Supply Center Columbus (DSCC) when a system  
application requires configuration control and the applicable SMD. DSCC will maintain a record of users and this list will be  
used for coordination and distribution of changes to the drawings. Users of drawings covering microelectronics devices (FSC  
5962) should contact DSCC-VA, telephone (614) 692-0544.  
6.5 Comments. Comments on this drawing should be directed to DSCC-VA, Columbus, Ohio 43218-3990, or telephone  
(614) 692-0547.  
6.6 Approved sources of supply. Approved sources of supply are listed in MIL-HDBK-103. The vendors listed in MIL-  
HDBK-103 have agreed to this drawing and a certificate of compliance (see 3.6 herein) has been submitted to and accepted by  
DSCC-VA.
