This document introduces the ispPAC-POWR1208P1 product from Lattice Semiconductor Corp. It is an in-system programmable power supply sequencing controller and precision monitor. It has the ability to monitor and control multiple power supplies, provides 8 output control signals, and has programmable digital and analog circuitry. In addition, it includes precision analog comparators for monitoring, embedded PLD for sequence control, programmable timers, and an embedded oscillator.
The ispPAC-POWR1208P1 is an in‑system programmable power‑supply sequencing controller and monitor that can manage up to eight separate power supplies while monitoring up to 12 analog inputs. It integrates programmable digital logic, 384 threshold levels, and four programmable 8‑bit timers, all configurable via a standard JTAG interface and the PAC‑Designer software.
Key specifications include a 44‑pin TQFP package, an operating temperature range of –40 °C to +85 °C, a core supply voltage of 2.7 V to 5.5 V, and built‑in 1 MHz clock generation. The device provides eight configurable output pins, four high‑voltage FET gate drivers, and a range of programmable analog comparators for precise voltage monitoring.
