Table 1. Gate Densities

Notes:

1. Based on NAND2 equivalents. Actual usable gate count is design-dependent. Estimates reflect a mix of functions including RAM.

2. Includes five pins that may or may not be reserved for JTAG boundary-scan, depending on user requirements.

4.Aeroflex offers four die sizes: KD (280 mils), KC (407 mils), KB (535 mils), and KM (677 mils).

Low-noise Device and Package Solutions

The UT0.6

CRH array family’s output drivers feature program-

mable slew rate control for minimizing noise and switching

transients. This feature allows the user to optimize edge charac-

teristics to match system requirements. Separate on-chip power

and ground buses are provided for internal cells and output drivers

which further isolate internal design circuitry from switching

noise.

In addition, Aeroflex offers advanced low-noise package tech-

nology with multi-layer, co-fired ceramic construction featuring

built-in isolated power and ground planes (see Table 2). These

planes provide lower overall resistance/inductance through pow-

er and ground paths which minimize voltage drops during periods

of heavy switching. These isolated planes also help sustain supply

voltage during dose rate events, thus preventing rail span

collapse.

Flatpacks are available with up to 352 leads; PGAs are available

with up to 299 pins and LGAs to 472 pins. Aeroflex’s flatpacks

feature a non-conductive tie bar that helps maintain lead integrity

through test and handling operations. In addition to the packages

listed in Table 2, Aeroflex offers custom package development

and package tooling modification services for individual

requirements.
