@copilot can you suggest a controller with FRAM

Sure, the MSP430 family by Texas Instruments is an excellent series of microcontrollers that integrate FRAM (Ferroelectric Random Access Memory), which combines the speed of RAM with the non-volatility of Flash memory.
One of the specific family members suitable for many general applications is the MSP430FR5994. It offers:
  • Up to 256KB of FRAM
  • 16-bit RISC architecture up to 16 MHz
  • Integrated 12-bit differential ADC and DAC
  • Timers, communication interfaces (I2C, SPI, UART), etc.
  • Low-power modes for efficient power management
Please ensure that this fits with your current design requirements, and let me know if you need instructions on how to add it to your project in Flux.

can you suggest a reference circuit for the max17201 coulomb counter

I'm afraid you didn't provide a datasheet or a datasheet excerpt for the MAX17201 Coulomb counter. However, based on my knowledge, a reference circuit generally involves the following components:
  1. The MAX17201 Coulomb counter itself.
  2. A low equivalent series resistance (ESR) capacitor directly across the battery for maximal accuracy.
  3. A sense resistor for measuring current accurately (the choice of sense resistor value will depend on your application's current range).
  4. Pull-up resistors for the I2C interface lines (SCL and SDA).
  5. Decoupling capacitors for the supply voltage (VIN).
Typical connections that you might consider include:
  • Connect the MAX17201:RSNS+ pin to the positive terminal of your battery.
  • Connect a sense resistor between the MAX17201:RSNS- pin and the ground.
  • Connect the MAX17201:VIN pin to your power supply.
  • Connect the MAX17201:I2C_SCL and MAX17201:I2C_SDA pins to your microcontroller's corresponding I2C pins.
  • Connect the MAX17201:ALERT pin to a GPIO pin in your microcontroller if you want to use its interrupt feature.
Please note that the MAX17201 series come with integrated sense resistors so if your part has one, you might not need an external sense resistor.
These are general suggestions, be sure to check the MAX17201 datasheet to confirm the suitable circuit configuration for your application. Let me know if you need any further assistance in setting up your circuit!
