nanoWatt XLP eXtreme Low Power PIC® MCUs
Microchip Technology Incorporated
Low Power Safety
Products with nanoWatt XLP have system supervisory
circuits specially designed for battery powered products.
■
The Low Power Brown-out Reset protects applications
when batteries are depleted or changed, yet consumes a
tiny 45 nA of current
■
The Real-time Clock Calendar is a fully independent
module that is unaffected by device resets
■
Using a dedicated on-chip oscillator, the WDT provides
protection against system failure for around 300 nA with
programmable time-outs lasting up to 25 days
XLP Battery Life Estimator (Free Download)
The XLP Battery Life Estimator is free PC software to aid in
developing eXtreme Low Power applications with Microchip’s
PIC MCUs featuring XLP technology. The utility allows users
to select the target MCU and battery type, as well as input
the current generated by the rest of the application. It
models the active current, sleep current, and the time spent
in each mode to provide an estimate of battery life.
■
Easy to Use
– Select your PIC MCU with XLP Technology
– Select your battery type
– Enter application Run and Sleep times
– Select peripherals and input application currents
– View battery life, average and maximum current estimates
■
Flexible
– Customizable to allow new device profi les and battery
specifi cations to be added
– Save profi les and compare results

Looking Beyond Low Power MCUs
As more electronic applications require low power or battery
power, energy conservation becomes paramount. Today’s
applications must consume little power, and in extreme
cases, last for up to 15-20 years, while running from a
single battery. To enable applications like these, products
with Microchip’s nanoWatt XLP Technology offer the
industry’s lowest currents for Run and Sleep, where extreme
low power applications spend 90%-99% of their time.

Low Power Peripheral Integration
Many of today’s low power products need advanced
peripherals. Microchip offers low power devices with
peripherals like USB, LCD, RTCC and mTouch™ capacitive
sensing. This eliminates the need for additional parts in the
application, saving cost, current and complexity.
