• Manufacturer Part Number: ispPAC10-01PI
• Description: In-System Programmable Analog Circuit
• Manufacturer: Lattice Semiconductor

T
*Note: During device JTAG programming, analog outputs will stop responding to normal input stimulus. This is because all
configuration information is erased and then re-written as part of a normal programming cycle, momentarily disrupting the input
to output signal path. Behavior is not predictable during either of these steps since the analog outputs are not clamped during
a programming cycle. Usually, however, the outputs will slew to either 0V (Ground) or 5V (V
behavior is partially determined by conditions existing immediately prior to device reprogramming and intermediate configura-
tions that occur during the process.
