Lattice Semiconductor announced the addition of two new devices to its second generation Power Manager II product family, the ispPAC-POWR1014 and ispPAC-POWR1014A. 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 and 1014A devices were designed from the ground up to provide a smaller footprint solution that has more features at a lower cost," said Stan Kopec, Lattice corporate vice president of marketing. "We have provided an increased number of control outputs, macrocells and programmable threshold comparators, while improving monitoring accuracy and including analog to digital conversion capability, all in a smaller package compared to our previous generation Power Manager products. The ispPAC-POWR1014 and 1014A devices implement all power management functions through simple logic equations using software, eliminating the need to select different and unique devices for each circuit board design."
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 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 devices have been ruggedized to operate across a wide range of power supply voltage from 2.8V to 3.96V.
The ispPAC-POWR1014 is designed to provide a complete power management solution in consumer, telecom and automotive applications, including customer premises equipments, plasma display panel TVs and in-cabin multimedia. The POWR1014A device addresses midrange applications such as advanced mezzanine cards, base station line cards, edge router line cards and servers that require power supply voltage measurement in addition to standard power management functions.
High-volume (100,000 units) pricing for the ispPAC- POWR1014 devices in the 48-pin TQFP package and industrial temperature range is $1.95. The ispPAC-POWR1014A devices will be priced ten percent higher. Samples are available now.
