TinyLogic® Ultra Low Power (ULP and ULP-A), The Lowest Power Logic Available
There are two series of ULTRA Low Power TinyLogic - ULP and ULP-A.
TinyLogic Ultra Low Power (ULP) offers the lowest power logic in the 0.9V to 3.3V VCC operating range. TinyLogic ULP devices consume up to 50% less power than LVC or LCX Single Gates and are ideal for portable applications such as cell phones, PDAs, digital cameras, etc., wherein extended battery life is critical.
TinyLogic Ultra Low Power-A (ULP-A) is also a power saving logic series however with higher drive and 3X the speed operating at .9V to 3.3 VCC. ULP-A is designed for timing-critical applications.

How does the TinyLogic ULP family save power in portable applications?
A cell phone example: Cell phones are typically comprised of four sections based on function (digital, memory, analog RF and display sections). TinyLogic’s Ultra Low Power devices usually fit into the cell phone’s digital section along with the DSPs and ASICs. Typically, the focus on standby power consumption is key because in most portable applications, the standby mode represents the highest or longest usage mode of the three modes (computational, transmit and standby). In the standby mode, the digital section consumes nearly 28% of the overall power consumption. Traditional TinyLogic UHS (or other LCX single gate logic) consumes up to 33% of this section’s power. By using TinyLogic ULP devices, the standby power consumption can be reduced to only 17% of the digital section’s power, reducing the overall standby power by 3%, extending battery life. What this means to the consumer? Assuming a standby time specification for a cellphone of 260 hours, then a 3% standby power savings will extend battery operation by 8 hours.
