ispPAC80
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.

Notes: (1) A wider input range of 0.7V to 4.3V is typical, but not guaranteed. Inputs larger than this will be clipped. Input signals are also subject
to common-mode voltage limitations. Refer to the table of conditions in this datasheet. (2) Refer to theory of operation section later in this datasheet
for explanation of differential voltage swing computation. (3) To insure full spec performance an additional auto-calibration should be performed
after initial turn-on and the device reaches thermal stability. (4) Although many hundreds of thousands of filter configurations are available using
ispPAC80, not every type will have corner frequencies available from exactly 50kHz to 500kHz, depending on the tables available from within PAC-
Designer filter design tools. The general specifications given under this heading are realized using the Elliptic filter types. (5) A Cauer elliptic filter
of type CC051042 (see datasheet text) is used to guarantee these specific filter accuracy specifications. It is assumed that all other configurations
available in PAC-Designer will exhibit equivalent performance according to the applicability of the individual filter type. Necessary limitations will
apply, however, when specifications do not directly apply. See the data sheet text, application notes and guides in PAC-Designer for specific filter
type considerations.
