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.
