Detailed

Specification

Scope

This specification describes the specific requirements for the microprocessor PC7457 in

compliance with Atmel standard screening.

Applicable

Documents

MIL-STD-883: Test methods and procedures for electronics

MIL-PRF-38535: Appendix A: General specifications for microcircuits

Requirements

General

The microcircuits are in accordance with the applicable documents and as specified

herein.

Design and Construction

Terminal Connections

Depending on the package, the terminal connections are as shown in Table 16, Table 3

and Figure 2.

Absolute Maximum

Ratings

Notes:

1. Functional and tested operating conditions are given in Table 3 on page 12. Absolute maximum ratings are stress ratings

only, and functional operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability

or cause permanent damage to the device.

2. Caution: V

DD/AVDD must not exceed OVDD/GVDD by more than 1V during normal operation; this limit may be exceeded for a

maximum of 20 ms during power-on reset and power-down sequences.

3. Caution: OVDD/GVDD must not exceed VDD/AVDD by more than 2V during normal operation; this limit may be exceeded for a

maximum of 20 ms during power-on reset and power-down sequences.

4. BVSEL must be set to 0, such that the bus is in 1.8V mode.

5. BVSEL must be set to HRESET or 1, such that the bus is in 2.5V mode.

6. L3VSEL must be set to ¬HRESET (inverse of HRESET), such that the bus is in 1.5V mode.
