Description
Lattice’s Power Manager II ispPAC-POWR1220AT8 is a
general-purpose power-supply monitor, sequence and
margin controller, incorporating both in-system pro-
grammable logic and in-system programmable analog
functions implemented in non-volatile E2CMOS® tech-
nology. The ispPAC-POWR1220AT8 device provides 12
independent analog input channels to monitor up to 12
power supply test points. Each of these input channels
offers a differential input to support remote ground
• Comparator status monitor
sensing, and has two independently programmable
• ADC readout
comparators to support both high/low and in-bounds/
• Direct control of inputs and outputs
out-of-bounds (window-compare) monitor functions. Six
• Power sequence control
general-purpose digital inputs are also provided for mis-
• Dynamic trimming/margining control
cellaneous control functions.
3.3V Operation, Wide Supply Range 2.8V to
3.96V
• In-system programmable through JTAG
• Industrial temperature range: -40°C to +85°C
• 100-pin TQFP package, lead-free option
The ispPAC-POWR1220AT8 provides 20 open-drain
digital outputs that can be used for controlling DC-DC
converters, low-drop-out regulators (LDOs) and opto-
couplers, as well as for supervisory and general-pur-
pose logic interface functions. Four of these outputs
