Programming Interface
Lattice Semiconductor’s ispDOWNLOAD
board. This cable plugs into a PC-compatible’s parallel port connector, and includes active buffer circuitry inside its
DB-25 connector housing. The other end of the ispDOWNLOAD cable terminates in an 8-pin 0.100” pitch header
connector which plugs directly into a mating connector provided on the PAC-POWR1208-EV evaluation board.
Prototype Area
A 19x18 grid (0.100” pitch) of uncommitted, plated through holes with annular-ring pads is provided as a user pro-
totyping area. Adjacent to this uncommitted array are two 19-hole rows providing easy connections to both power
and ground. This prototyping area allows the user to build small circuits directly on the evaluation board. In the case
of larger circuits, the evaluation board can be readily connected into off-board circuitry through P5, into which can
be mounted a 20 x 2 header.
Power Supply Considerations
The ispPAC-POWR1208 operates with power supplies ranging from 2.25V to 5.5V, and allows for separate core
(VDD) and I/O (VDDINP) voltages. Voltages ranging from 0 to 5.75V may be monitored at any of the 12 VMONx
pins independent of the values of VDD and VDDINP. For device programming, however, VDD MUST be set to 3.3V.
