scope:

This drawing documents three product assurance class levels consisting of space application (device class V), high reliability (device classes M and Q), and nontraditional performance environment (device class N). A choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN). When available, a choice of Radiation Hardness Assurance (RHA) levels are reflected in the PIN. For device class N, the user is cautioned to assure that the device is appropriate for the application environment.

The PIN is as shown in the following example:

Device classes N, Q, and V RHA marked devices meet the MIL-PRF-38535 specified RHA levels and are marked with the appropriate RHA designator. Device class M RHA marked devices meet the MIL-PRF-38535, appendix A specified RHA levels and are marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device.

The device type(s) identify the circuit function as follows:

Device type Generic number Circuit function 01 1/ 87C751 CMOS 8-bit microcontroller with 2 kilobytes EPROM memory 02 87C751 CMOS 8-bit microcontroller with 2 kilobytes one time programmable EPROM memory 03 1/ 87C751-16 CMOS 8-bit microcontroller with 2 kilobytes EPROM memory 04 87C751-16 CMOS 8-bit microcontroller with 2 kilobytes one time programmable EPROM memory 05 87C751 CMOS 8-bit microcontroller (3.5 to 12 MHz) one time programmable EPROM memory 06 87C751-16 CMOS 8-bit microcontroller (3.5 to 16 MHz) one time programmable EPROM memory 07 87C751 CMOS 8-bit microcontroller (3.5 to 12 MHz) one time programmable EPROM memory 08 87C751-16 CMOS 8-bit microcontroller (3.5 to 16 MHz) one time programmable EPROM memory

The device class designator is a single letter identifying the product assurance level as follows:

Device class Device requirements documentation M Vendor self-certification to the requirements for MIL-STD-883 compliant, non-JAN class level B microcircuits in accordance with MIL-PRF-38535, appendix A N Certification and qualification to MIL-PRF-38535 with a nontraditional performance environment 2/ Q or V Certification and qualification to MIL-PRF-38535

The case outline(s) are as designated in MIL-STD-1835 and as follows:

Outline letter Descriptive designator Terminals Package style L 1/ GDIP3-T24 or CDIP4-T24 24 Dual-in-line package X MS-001-AF 3/ 24 Plastic dual-in-line package 3 1/ CQCC1-H28 28 Square chip carrier package

The lead finish is as specified in MIL-PRF-38535 for device classes N, Q, and V or MIL-PRF-38535, appendix A for device class M.
