scope:

This drawing describes device requirements for class B microcircuits in accordance with 1.2.1 of MIL-STD-883, "Provisions for the use of MIL-STD-883 in conjunction with compliant non-JAN devices".

The complete PIN shall be as shown in the following example:

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

Device type Generic number Circuit function 01 87C51FB-12 High performance CHMOS single-chip 8-bit microcontroller 02 87C51FB-16 High performance CHMOS single-chip 8-bit microcontroller 03 87C654 High performance CHMOS single-chip 8-bit microcontroller 04 87C654-16 High performance CHMOS single-chip 8-bit microcontroller 05 87C654 High performance CHMOS single chip 8-bit microcontroller with 16K bytes of one time programmable EPROM memory (3.5 to 12 MHz 06 87C654-16 High performance CHMOS single-chip 8-bit microcontroller with 16K bytes of one time programmable EPROM memory (3.5 to 16 MHz

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

Outline letter Descriptive designator Terminals Package style M GQCC1-J44 or CQCC2-J44 44 ceramic chip carrier "J" leaded package 1/ T See figure 1 44 ceramic chip carrier, "J" leaded package 1/ U CQCCQ-N44 44 square chip carrier package 1/ X GDIP1-T40 or CDIP2-T40 40 dual-in-line package 1/ Z See figure 2 44 ceramic chip carrier, gull wing leaded package 1/

The lead finish shall be as specified in MIL-STD-883 (see 3.1 herein). Finish letter "X" shall not be marked on the microcircuit or its packaging. The "X" designation is for use in specifications when lead finishes A, B, and C are considered acceptable and interchangeable without preference.
