scope:

This specification covers the detail requirements for a monolithic N-channel, silicon gate direct memory access controller. One product assurance class and a choice of case outlines and lead finishes are provided and are reflected in the complete part number.

The part number shall be in accordance with MIL-M-38510, with the exception that the "JAN" or "J" certification shall not be used.

The device types shall be as follows:

Device type Clock frequency Circuit 01 4.0 MHz Direct memory 02 2.5 MHz access controller

The device class shall be the product assurance level as defined in MIL-M-38510.

The case outline shall be designated as follows:
