LOW POWER MICRO CONTROLLERS

You can use a 0.9-5v step up booster to power your pic16f887.

Lithium batteries provide 3.7v - 4.2v depending on the charge condition. Well, you can use switching boost converter that supports 3.3v -4.2v input with 5v output.

Current is depends on the other peripherals.

Low Power Microcontrollers. Analog Devices' ultra low power microcontroller allows edge nodes to intelligently process localized data with the smallest amount of system power needed. This allows customers to extend battery life and extend the time between charges allowing longer use.

Ultra Low Power Microcontrollers. Analog Devices' ultra low power (ULP) microcontroller allows edge nodes to intelligently process localized data with the smallest amount of system power needed. This allows customers to extend battery life and extend the time between charges allowing longer use. Smaller battery sizes and longer time between in-field product replacements provide cost saving for our customers.

ULP Microcontrollers and sensor signal processors utilize processor cores with integrated power management for processing, control, and connectivity. Some of our ultra low power technology such as Sensor Strobe enable over 10X system power savings when combined with Analog Devices’ digital sensors and ultra low power transceivers. They offer robust features for high volume applications and security features for IP protection.

Our ultra low power MCUs offer intelligence at the edge nodes for IoT Applications by allowing local decision making to happen at the node allowing only the most important data to be sent to the cloud.

Yes! you can use this battery to power up your micro-controller, but you need to use a boost converter or regulator, either use a module or just its IC, then connect your 3.7V battery with its input pins and then place a digital multi-meter at output pins to check the output voltages, rotate the knob of potentiometer/variable resistors when your measurement is around 5V or 5.1V connect Vcc and Gnd pins of micro-controller with output of this module. Here I recommend you to get connect with the SSLA platform technical support team for getting better assistance regarding your queries and project support.

In today’s energy consumption and safety-conscious world, collecting and using accurate information about ambient temperature and humidity and the concentration of carbon monoxide  is of critical importance. It is equally important to make measurements and provide control information or actions in a cost-effective manner.Advances in single-chip low-power-consuming microcontrollers that utilize a unique RC-type analog-to-digital converter  now allow designers to meet these challenges in creating products that are used to monitor temperature or humidity and detect dangerous levels of carbon monoxide. These new microcontrollers enable product designers to create products and systems that record, display, and use the data to manage environmental control units and energy consumption as well as monitor perishable product quality—all in real time. In many of these applications the activity of collecting and using environmental data, in the -40°C to 85°C range,is performed by battery operated handheld or remotely installed products. The rising demand for low power consumption in products that monitor the environment and harvest energy from their local environment are perfect applications for these devices due to their low power consumption.

In my opinion, you can absolutely power the PIC with a li-po or li-ion battery. As the datasheet of the microcontroller gives an voltage range of  (2.0V to 5.5V). but if you are using ADC for your application, this will not work.
