Lattice Announces Addition of Precision Power Manager to Programmable Mixed-Signal Product Portfolio

    HILLSBORO, Ore.--(BUSINESS WIRE)--Feb. 8, 2005--

New Device Monitors Power Supply Voltages Down to 0.7V with 0.5% Precision
    Lattice Semiconductor Corporation (Nasdaq:LSCC) today announced the extension of its revolutionary ispPAC(R) Power Manager programmable mixed-signal product family with the production release of the Precision Power Manager -- Power1208P1 device. The Power1208P1 device, like its predecessor the Power1208, provides a complete solution for printed circuit board (PCB) power sequencing and management through an optimized set of programmable digital and analog functions. The Power1208P1 also extends the power and versatility of the Lattice Power Manager products: the analog inputs are capable of monitoring power supplies with voltages down to 0.67V, and are able to detect faults with greater than 0.5% precision. In addition, the Precision Power Manager can detect a power-off condition (i.e., power supply voltage less than 80 mV). The Power1208P1 is pin compatible with the existing Power1208, and is available in a compact 44-pin Thin Quad Flat Pack (TQFP) package.

    Increasing Emphasis on Precise Fault Detection

    The complexity of power supply management has increased dramatically in recent years as the number of voltages found on the typical PCB has risen sharply. The use of core power supply voltages less than the standard 1.2V is becoming more common. Further, advanced integrated circuit tolerance of power supply voltage variation is also tightening. The ability of the Power1208P1 to simultaneously monitor all 12 power supply inputs provides rapid, accurate power supply fault detection, reducing fault propagation and consequently improving overall system reliability.
    "Managing today's power supply voltages with greater precision can only be achieved by using mixed-signal devices with higher accuracy," said Stan Kopec, Lattice vice president of corporate marketing. "With the addition of the Power1208P1 device, designers can now employ our standardized power management approach that includes PCBs that use power supplies of 1.2V or less."

    About the Power1208P1

    The Power1208P1 features 12 high precision analog power monitor inputs. Each analog input has programmable threshold (384 steps + power supply discharge detection) synchronous comparators with a fault detection precision of 0.5%. In addition, the 1208P1 device is equipped with on-chip programmable voltage references for supply monitoring, 4 noise-immune digital inputs and 4 open-drain digital outputs for system control interfacing, 4 programmable timers with an on-chip 1 MHz oscillator for delay control and a 16 macrocell Complex PLD (CPLD) to implement sequencing and control functions. The Power1208P1 is ruggedized to operate reliably in noisy power supply environments from 2.7V to 5.5V.
    Lattice 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 EECMOS(R) elements on the devices using an IEEE1149.1 boundary scan protocol.
    Applications for Power Manager devices include telecom and networking systems, storage systems, servers, test equipment and automotive electronics. Programmable features make Power Manager devices ideal for controlling multiple power supplies in conjunction with a wide range of regulator and switching technologies. Together with N-channel switching FETs, LDO (Low Drop Out) regulators, and/or DC-DC convertors (power bricks), the Power1208P1, Power1208 and Power604 devices provide compact, flexible power supply control solutions.

    PAC-Designer(R) Version 3.3 Supports Enhanced Instruction Set
    LogiBuilder

    The Precision Power Manager device is supported by the latest version PAC-Designer software, an intuitive schematic design entry and simulation tool. Complex sequencing and monitoring functionality can be efficiently designed through easy-to-use pull-down menus in PAC-Designer's LogiBuilder module. The latest version of the tool features a new and improved instruction set that enables the user to implement complex functionality more efficiently. Designs can be completely verified using the tool's built-in waveform simulator. The PAC-Designer software is available for download from Lattice at www.latticesemi.com.
    The PACsysPOWR1208P1 evaluation kit enables designers to quickly build prototypes of their circuit implementations using the Power1208P1 in order to verify functionality. Designs implemented using the PAC-Designer software are downloaded into the device through a serial ispDOWNLOAD(R) cable that connects to a PC's parallel port. The kit contains an evaluation board for an ispPAC Power Manager device, an ispDOWNLOAD cable, and the PAC-Designer version 3.3 software.

    Pricing and Availability

    Prices for the Power1208P1 device begin at $9.95 in 10,000 piece quantities. The device in a 44-pin TQFP package (industrial temperature grade, -40 C to +85 C) is available now.
    PACsysPOWR1208P1 evaluation kits are also available through authorized Lattice distributors or on the Lattice web site at a price of $149.
