Description
The ispPAC80 is a member of the Lattice family of In-System
Programmable analog circuits, digitally configured via non-
volatile E2CMOS technology.
Analog building blocks, called PACell(s), replace traditional
analog components such as opamps, eliminating the need for
external resistors and capacitors. With no requirement for
external configuration components, ispPAC80 expedites the
design process, simplifying prototype circuit implementation
and change, while providing high-performance integrated func-
tionality. With all components on chip, there is no longer a
concern of performance degradation due to component mis-
match or other external factors. The ispPAC80 provides reliable
and repeatable performance, every time.
Designers configure the ispPAC80 and verify its performance
using PAC-Designer, an easy to use, Microsoft Windows
compatible program. A filter configuration database is provided
whereby thousands of different configurations can be realized.
No special understanding of filter synthesis is required beyond
that of general specifications such as corner frequency and
stopband attenuation, etc. The software lists the possible
choices that meet the designer’s specifications which can then
be
loaded
directly
into
either
of
two
device
(A/B) configurations from the lookup table. Device program-
ming is supported using PC parallel port I/O operations.
The ispPAC80 is configured through its IEEE Standard 1149.1
compliant serial port. The flexible In-System Programming
capability enables programming, verification and reconfig-
uration, if desired, directly on the printed circuit board.
