New and original SimpleLink™ 32-bit Arm Cortex-M3 Sub-1 GHz wireless MCU with 128kB Flash of TI
DescriptionThe CC1310 device is a cost-effective ultra-low power sub-1GHz radio frequency device, built by Texas Instruments (TI)™ and part of the SimpleLink™ microcontroller (MCU) platform.The platform includes Wi-Fi®, Bluetooth® low energy, sub-1GHz, Ethernet, Zigbee®, Thread and host MCU.All these devices share a common, easy-to-use development environment that includes a single core software development kit (SDK) and a rich toolset.With the one-time integration of the SimpleLink platform, users can add any combination of devices from the portfolio to their designs, enabling 100% code reuse as design requirements change.
With extremely low active RF and MCU current consumption and flexible low-power modes, the CC1310 device ensures excellent battery life and enables long-range operation on small coin cell batteries and in energy harvesting applications.
The CC1310 device is a member of the CC13xx and CC26xx families of cost-effective, ultra-low power wireless MCUs capable of supporting sub-1GHz radio frequencies.The CC1310 device combines a flexible, ultra-low power RF transceiver with a powerful 48MHz Arm® Cortex®-M3 microcontroller on a platform that supports multiple physical layer and RF standards.A dedicated radio controller (Cortex®-M0) handles low-level RF protocol commands stored in ROM or RAM, thus ensuring ultra-low power consumption and flexibility.The CC1310 device achieves low power consumption without sacrificing RF performance; the CC1310 device has excellent sensitivity and robustness (selectivity and blocking)
performance.
The CC1310 device is a highly integrated true single-chip solution integrating a complete RF system and on-chip DC/DC converter.
Sensors are processed in an ultra-low-power manner by a dedicated ultra-low-power autonomous MCU (which can be configured to handle analog and digital sensors), so the main MCU (Arm® Cortex®-M3) can maximize sleep time.
The CC1310 device's power and clock management system and radio system require specific configuration and are handled by software to operate correctly, which is implemented in TI-RTOS.TI recommends using this software framework for all application development processes for this device.The complete TI-RTOS and device drivers are available as free source code.

New and original Wide VIN, Multi-Output DC/DC Converter and PowerPath Controller of Linear Technology DescriptionThe LTC®3101 is a complete power management solution
for low power portable devices. It provides three high
effi ciency switching DC/DC converters which seamlessly
transition from battery to USB/wall adapter power when
available. A synchronous buck-boost regulator provides
complete fl exibility, allowing operation from a single
Li-Ion/Polymer battery, 2 to 3 AA cells, a USB port or any
other power source operating from 1.8V to 5.5V.
Two always-alive outputs, a 50mA LDO and a 200mA MAX
output that tracks the higher voltage input supply, provide
power for critical functions or additional external regula-
tors. Flash memory cards can be directly powered from
the protected 100mA Hot Swap output. Pushbutton control
logic and a programmable-duration microprocessor reset
generator simplify interfacing to a microprocessor while
internal sequencing and independent enable pins provide
flexible power-up options. The LTC3101 is available in a low
profi le (0.75mm) 24-lead 4mm×4mm QFN package
