scope:

This specification covers the detail requirements for monolithic silicon, CMOS, 64K words × 8 bit, electrically clearable, writable read-only memory microcircuits. Two product assurance classes (S and B), a choice of lead finish and two package types are provided for each device and are reflected in the complete Part Number or Identifying Number (PIN).

The PIN shall be in accordance with MIL-M-38510.

The device types shall be as follows:

Device Circuit Access type organization time Endurance 01 64K words × 8 bit 300 ns 100 cycles 02 64K words × 8 bit 300 ns 1,000 cycles 03 64K words × 8 bit 250 ns 100 cycles 04 64K words × 8 bit 250 ns 1,000 cycles 05 64K words × 8 bit 200 ns 100 cycles 06 64K words × 8 bit 200 ns 1,000 cycles 07 64K words × 8 bit 150 ns 100 cycles 08 64K words × 8 bit 150 ns 1,000 cycles 09 64K words × 8 bit 120 ns 100 cycles 10 64K words × 8 bit 120 ns 1,000 cycles

The device class shall be the product assurance level as defined in MIL-M-38510.

The case outlines shall be designated as follows:

Letter Case outline (see MIL-M-38510, appendix C) X See figure 1 (32-lead, 1.685" × .600" × .225"), dual-in-line package Y C-12 (32-terminal, .560" × .458" × .120"), rectangular chip carrier package Z See figure 1 (32-lead, .830" × .416" × .120"), flat package
