Lattice Semiconductor Corporation’s (NASDAQ: LSCC) LA-ispPAC-POWR1014 and LA-ispPAC-POWR1014A have been characterized and qualified to meet the certification requirements of the AEC-Q100 standard as defined by the Automotive Electronics Council (AEC). The two devices are automotive versions of the Power Manager II product family. 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. Lattice AEC-Q100 qualified devices are designated as Lattice Automotive, or “LA.” Production quantities of the new devices will be available later in Q1 2008, and Lattice can provide standard PPAP (Production Part Approval Process) documentation to automotive customers who require it.
The 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 LA-ispPAC-POWR1014 device integrates a 24 Macrocell PLD and dual precision voltage monitoring comparators with an accuracy of 0.3%. 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 or processor 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.
Designs for the LA-ispPAC-POWR1014 and the LA-ispPAC-POWR1014A are implemented using the Windows-based Lattice PAC-Designer® Software version 4.98. Prices for the LA-ispPAC-POWR1014/A devices in the 48-pin PB-free TQFP package and automotive temperature range are as low as $2.25 (100KU+). The devices will be available for delivery in the 2nd half of 2008. Samples are available now.
