Programmable clock frequency
Programmable timer pre-scaler
External clock support
The Lattice ispPAC-POWR1208 incorporates both in-
system programmable logic and in-system programma-
ble analog circuits to perform special functions for
■ Programmable Output Con?gurations
? Four digital outputs for logic and power supply
control
? Four fully programmable gate driver outputs for
FET control, or programmable as four additional
digital outputs
? Expandable with ispMACH? 4000 CPLD
■ 2.25V to 5.5V Supply Range
power supply sequencing and monitoring. The ispPAC-
POWR1208 device has the capability to be con?gured
through software to control up to eight outputs for power
supply sequencing and 12 comparators monitoring sup-
ply voltage limits, along with four digital inputs for inter-
facing to other control circuits or digital logic. Once
con?gured, the design is downloaded into the device
through a standard JTAG interface. The circuit con?gu-
ration and routing are stored in non-volatile E 2 CMOS.

PAC-Designer, ? an easy-to-use Windows-compatible
software package gives users the ability to design the
logic and sequences that control the power supplies or
FET driver circuits. The user has control over timing
functions, programmable logic functions and compara-
tor threshold values as well as I/O con?gurations.
