Design and Construction

Terminal Connections

Depending on the package, the terminal connections shall be as shown in Figure 2 and

Figure 3.

Lead Material and Finish

Lead material and finish shall be any option of MIL-M-38535.

Package

The macrocircuits are packaged in hermetically sealed ceramic packages, which con-

form to case outlines of MIL-M-38535 appendix A (when defined):

•

132-pin Ceramic Pin Grid Array (PGA),

•

132-pin Ceramic Quad Flat Pack (CERQUAD).

The precise case outlines are described in Figure 2 and Figure 3.

Electrical Characteristics

Notes:

1. The values shown are typical. The typical value varies as shown, based on how many IMP on-chip peripherals are enabled

and the rate at which they are clocked.

2. LPREC = 0. Divider = 2.

3. LPREC = 1. Divider = 1024.

4. The stated frequency must be externally applied to EXTAL only after the IMP has been placed in the lowest power mode

with LPREC = 1. The 68000 core is not specified to operate at this frequency, but the rest of the IMP is. In this configuration,

the user does not divide the clock internally using the LPCD4-LPCD0 bits in the system control register.
