MIL-M-38510-207 Microcircuit, Digital, 256-Bit, Schottky, 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, tungsten W, titanium tungsten TiW, or zapped vertical emitter ZVE as the fusible link or programming element. Two product assurance classes and a choice of case outlines and lead material and finishes are provided for each type 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 For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, see 6.4.

Inactive for new design after 24 July 1995

This specification is approved for use by all Departments and Agencies of the Department of Defense.

The requirements for acquiring the product herein shall consist of this specification sheet and MIL-PRF 38535.

1.  SCOPE

1.1  Scope.  This specification covers the detail requirements for monolithic silicon, PROM microcircuits which employ thin film nichrome (NiCr) resistors, tungsten (W), titanium tungsten (TiW), or zapped vertical emitter (ZVE) as the fusible link or programming element.  Two product assurance classes and a choice of case outlines and lead material and finishes are provided for each type 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  For this product, the requirements of MIL-M-38510 have been superseded by MIL-PRF-38535, (see 6.4).

1.2  Part or Identifying Number (PIN).  The PIN is in accordance with MIL-PRF-38535, and as specified herein.

1.2.1  Device types.  The device types are as follows:

Device type                                                   Circuit

01, 03                        32 word / 8 bits per word PROM with open collector

02, 04                        32 word / 8 bits per word PROM with tri-state output

1.2.2  Device class.  The device class is the product assurance level as defined in MIL-PRF-38535.

1.2.3  Case outlines.  The case outlines are as designated in MIL-STD-1835 and as follows:
