Description
The ispPAC20 is a member of the Lattice family of In-
System Programmable analog circuits, digitally configured
via nonvolatile E
2
CMOS technology.
Analog building blocks, called PACblocks, replace tradi-
tional analog components such as opamps and active
filters, eliminating the need for most external resistors and
capacitors. Also included are an 8-bit DAC and dual com-
parators. With no requirement for external configuration
components, ispPAC20 expedites the design process,
simplifying prototype circuit implementation and change,
while providing high-performance integrated functionality.
Designers configure the ispPAC20 and verify its perfor-
mance using PAC-Designer
, an easy-to-use, Microsoft
Windows
compatible program. Device programming is
supported using PC parallel port I/O operations.
The ispPAC20 is configured through its IEEE Standard
1149.1 (JTAG) compliant serial port. The flexible In-System
Programming capability enables programming, verification
and reconfiguration if desired, directly on the printed circuit
board.
