TheLTP5901-IPM/LTP5902-IPMistheworld’smostenergy
efficient IEEE 802.15.4 compliant platform, enabling bat-
tery and energy harvested applications. With a powerful
32-bit ARM Cortex-M3, best-in-class radio, flash, RAM
and purpose-built peripherals, Eterna provides a flexible,
scalable and robust networking solution for applications
demandingminimalenergyconsumptionanddatareliability
in even the most challenging RF environments.
Shown in Figure 13, Eterna integrates purpose-built
peripherals that excel in both low operating-energy con-
sumption and the ability to rapidly and precisely cycle
between operating and low-power states. Items in the
gray shaded region labeled Analog Core correspond to
the analog/RF components.
POWER SUPPLY
Eterna is powered from a single pin, VSUPPLY, which
powers the I/O cells and is also used to generate internal
supplies.Eterna’stwoon-chipDC/DCconvertersminimize
Eterna’s energy consumption while the device is awake. To
conserve power the DC/DC converters are disabled when
the device is in low power state. Eterna’s power supply
conditioningarchitecture,includingthetwointegratedDC/
DC converters and three integrated low dropout regula-
tors, provides excellent rejection of supply noise. Eterna’s
operating supply voltage range is high enough to support
direct connection to lithium-thionyl chloride (Li-SOCl2)
sources and wide enough to support battery operation
over a broad temperature range.
