Lattice Semiconductor Corporation has announced the addition of the programmable, ultra low cost ispPAC-POWR607 device to its second generation Power Manager II product family. The new devices achieve a sub-$1.00 price point in high volume, targeting many cost-sensitive power management applications in consumer markets such as LCD TV, automotive multimedia systems, GPS receivers, Multimedia Terminal Adapters and set-top-boxes. The ispPAC-POWR607 device integrates a complete set of power management functions that typically require multiple ICs.
The POWR607 device supports any 16-bit or 32-bit microprocessor-based system. Designers traditionally have used a design-specific set of discrete off-the-shelf devices to generate the CPU Reset, Power Supply Fault Interrupts, and Watchdog Timers for each microprocessor-based design. The POWR607 device can implement all these functions through logic programmed into its on-chip PLD, which results in a standardized, lower cost design solution.
The POWR607 device uses Lattice's Power Manager architecture. The device can monitor up to 6 circuit board power supplies and generate signals such as a CPU Reset, including pulse stretching and power supply fault interrupt, using the on-chip 16 macrocell CPLD, four programmable timers, and 7 outputs (two of which also can be configured as high voltage MOSFET drivers). The POWR607 device can be powered down using an external logic signal, or by an internally generated signal. Once in the power down state, the device draws a mere 10 microamperes from the power supply. The POWR607 devices are packaged in space-saving 5mm × 5mm QFN packages.
Due to its low cost, very small footprint and low power standby feature, the ispPAC-POWR607 is an ideal power management solution in handheld consumer, telecom and industrial applications.
All Power Manager devices, including the POWR1220AT8, POWR1014/A, POWR6AT6 and POWR607, provide a standard, off-the-shelf programmable mixed signal solution for power management across multiple circuit boards. This solution improves reliability, speeds time-to-market and reduces cost.
Designs for the ispPAC-POWR607 are implemented using the Windows-based Lattice PAC-Designer Software version 4.7. This software is available for download free of charge from the Lattice website at www.latticesemi.com.
Pricing and availability
