Description
Experience Level: Intermediate
Estimated project duration: less than 1 week
This job is suitable for intermediate / expert electronics engineers who have a good knowledge of microcontroller varieties (Microchip PIC, Atmel, Maxim, etc...) and an understanding of their implementations and characteristics.
I am designing a small and relitively sinmple electronics project and I need to select a suitable microcontroller. The aim of the project is to measure the voltage of a 18650 Li-Ion Cell, then display the result using 7 LEDs (as shown in the attached diagram). I DO NOT need help designing the whole circuit or PCB, I'm only asking for advice on selecting a suitable microcontroller (including any supporting-circuitry) to use within my project.
The microcontroller must:
- Be cost-effective (as cheap as possible, ideally under £3 per unit)
- Be a reputable brand and available in the UK such as Microchip PIC, Atmel, Maxim, etc (other brands considered)
- Be through-hole (rather than SMD, for easy hand-soldering)
- Function at an 18650 cell's voltage between undercharged to overcharged (ideally 2v - 5v)
- Have a minimum of 7 digital outputs (to switch on/off the LEDs)
- Have a minimum of 1 analogue input (to measure the cells voltage)
- Not be already embedded on a PCB (the PCB will be designed around the microcontroller)
I'm therefore looking for help to find a microcontroller which meets the listed criteria above if possible. Additional/supplementary circuitry may include ADCs & DACs, voltage-dividers, voltage-regulators; including any other components/circuitry required for proper operation. I'm NOT looking for embedded microcontrollers such as Arduino boards (or similar). I'm very familiar with these options but I'm looking for an alternative which I'm able to design into my own PCB.
Attached Files:
- Product Diagram, showing the implementation and aim of the project using a diagram
- LED Datasheet (the red, yellow & green LEDs are all the same)
- 18650 Li-Ion Cell Discharge Graph (Voltage & Capacity)
