MIL-M-38510-201 Microcircuits, Digital, 512-Bit, Bipolar, Programmable Read-Only Memory Prom, Monolithic SiliconThis specification covers the detail requirements for monolithic silicon, PROM microcircuits which employ thin film nichrome NiCr resistors as the fusible link or programming element. One product assurance class and a choice of case outlines and lead finishes are provided and are reflected in the complete part number. For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

MIL-M-38510/201D

6.5  Abbreviations, symbols, and definitions.  The abbreviations, symbols, and definitions used herein are defined in MIL-PRF-38535, MIL-HDBK-1331, and as follows:

GND ............................................ Electrical ground (common terminal). IIN  ............................................... Current flowing into an input terminal. VIN  .............................................. Voltage level at an input terminal.

VIC  .............................................. Input clamp voltage.

6.6  Logistic support.  Lead materials and finishes (see 3.4) are interchangeable.  Unless otherwise specified, microcircuits acquired for Government logistic support will be acquired to device class B (see 1.2.2), lead material and finish C (see 3.4).  Longer length leads and lead forming should not affect the part number.  It is intended that spare devices for logistic support be acquired in the unprogrammed condition (see 3.8.1) and programmed by the maintenance activity, except where use quantities for devices with a specific program or pattern justify stocking of preprogrammed devices.

6.7  Substitutability.  The cross-reference information below is presented for the convenience of users. Microcircuits covered by this specification will functionally replace the listed generic-industry type.  Generic-industry microcircuit types may not have equivalent operational performance characteristics across military temperature

ranges or reliability factors equivalent to MIL-M-38510 device types and may have slight physical variations in relation to case size.  The presence of this information should not be deemed as permitting substitution of generic-industry

types for MIL-M-38510 types or as a waiver of any of the provisions of  MIL-PRF-38535.

6.8 Change from previous issue.  Marginal notations are not used in this revision to identify changes with respect to the previous issue, due to the extensiveness of the changes.
