Lattice Semiconductor has announced the addition of two new devices to its second generation Power Manager II product family, the ispPAC-POWR1014 and ispPAC-POWR1014A. The Power Manager II family is a functional superset of Lattice's ispPAC Power Manager programmable mixed signal devices, which provide a complete power management solution for a printed circuit board (PCB) through an optimized set of programmable digital and analog functions.
The new ispPAC-POWR1014 device replaces power management functions typically requiring multiple ICs, including Reset Generators, Voltage Supervisors, Sequencers and Trackers. In addition, the ispPAC-POWR1014A device replaces Analog-to-Digital Converter (ADC) ICs used for power supply voltage measurements, controlled through a standard I2C interface.
All Power Manager devices provide a standard, off-the-shelf programmable mixed-signal solution for power management that enhances reliability and speeds time-to-market. Analog features such as input comparator thresholds and digital functions such as supply control sequences are programmed into non-volatile E2CMOS elements on the devices using an IEEE1149.1 protocol.
The POWR1014 device integrates a 24 Macrocell ruggedized CPLD and dual precision voltage monitoring comparators with an accuracy of 0.2%.
In addition, the POWR1014A device integrates a 10-bit Analog to Digital Converter (ADC) for voltage measurements and an I2C interface that enables a microcontroller to read the status of all the comparators, inputs as well as outputs. Both the POWR1014 and POWR1014A devices have been ruggedized to operate across a wide range of power supply voltage from 2.8V to 3.96V.
Due to its low cost and very small footprint, the ispPAC-POWR1014 is ideally suited to provide a complete power management solution in consumer, telecom and automotive applications, including customer premises equipments (CPE), Plasma Display Panel TVs and in-cabin multimedia.
The POWR1014A device addresses midrange applications such as Advanced Mezzanine Cards (AMC), PrPMC, basestation line cards, edge router line cards and servers that require power supply voltage measurement in addition to standard power management functions.
Designs for the ispPAC-POWR1014 and the ispPAC-POWR1014A are implemented using the Windows-based Lattice PAC-Designer Software version 4.3.The PAC-Designer 4.3 software is available for download free of charge from the Lattice website at www.latticesemi.com.
