Hess DEFENSE SUPPLY CENTER COLUMBUS CHECKED BY COLUMBUS, OHIO 43218-3990 STANDARD 1. SCOPE 1.1 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. 1.2 PIN. The PIN is as shown in the following example: 5962 - 87684 01 M X X Federal RHA Device Device Case Lead stock class designator type class outline finish designator (see 1.2.1) (see 1.2.2) designator (see 1.2.4) (see 1.2.5) / (see 1.2.3) / Drawing number 1.2.1 RHA designator. 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. 1.2.2 Device type(s). The device type(s) identify the circuit function as follows: Device type Generic number Circuit function Temperature range 01 87C51 8-bit microcontroller with 4k-bytes -55C to 125C EPROM memory. (3.5 to 12MHz) 02 87C51-16 8-bit microcontroller with 4k-bytes -55C to 125C EPROM memory. (3.5 to 16MHz) 03 87C51 8-bit microcontroller with one time -40C to 85C programmable memory. (3.5 to 12MHz) 04 87C51-16 8-bit microcontroller with one time -40C to 85C programmable memory. (3.5 to 16MHz) 05 87C51 8-bit microcontroller with one time -55C to 125C programmable memory. (3.5 to 12MHz) 06 87C51-16 8-bit microcontroller with one time -55C to 125C programmable memory. (3.5 to 16MHz) 07 87C51 8-bit microcontroller with 4k-bytes one time -55C to 125C programmable memory. (3.5 to 12MHz) 08 87C51-16 8-bit microcontroller with 4k-bytes one time -55C to 125C programmable memory. (3.5 to 16MHz) 1.2.3 Device class designator. 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 (encapsulated in plastic) Q or V Certification and qualification to MIL-PRF-38535 SIZE STANDARD 5962-87684 A MICROCIRCUIT DRAWING DEFENSE SUPPLY CENTER COLUMBUS REVISION LEVEL SHEET COLUMBUS, OHIO 43218-3990 G 2 DSCC FORM 2234 APR 97
