The ispPAC80 is a member of the Lattice family of In-System Programmable analog circuits, digitally configured via non-2 (R) volatile E CMOS technology.
Analog building blocks, called PACell(TM)(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(TM), 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 1149.1compliant serial port. The flexible In-System Programming capability enables programming, verification and reconfig-uration, if desired, directly on the printed circuit board.
