PSoC programmable analog & digital resources integrate everything shown in light blue below. Click on the colored blocks to view or sample the recommended PSoC Components.


The flexibility of PSoC allows you to customize each colored block, or PSoC Component, to meet your design requirements through the easy-to-use PSoC Creator Software IDE.  These Components are available as pre-built, pre-characterized IP elements in PSoC Creator.

Design Considerations

Fertility Monitors are devices that monitor fertility levels by monitoring hormone levels. A fertility monitor may analyze hormone levels in bodily fluids, resistance in bodily fluids, basal temperature, or a combination of these methods. There are three standard methods for monitoring hormone levels:

Urine: Tests for luteinizing hormone surge
Saliva: Detects changing electrolyte levels
Temperature: Monitors basal body temperature to predict cycles

Each of these sensing methods require an analog front end (AFE) to perform the necessary measurements. Fertility Monitors are battery powered devices so active power consumption and sleep current are important considerations. A fertility monitor also includes a display, memory for storage of fertility reading history, serial communication such as USB. A touchscreen or capsense user interface may also be seen in fertility monitors.
PSoC® 3 and PSoC 5 provide a scalable platform which provides all the requisite circuitry to provide a configurable Fertility Monitor on Chip, including:

  •  High precision Analog front end, including a 0.1% accurate Voltage reference and up to 20 bits of resolution
  •  Circuitry for sequencing and driving LED for optical measurement of the test strip and the circuitry for reading the photodiode to create a full optical measurement system
  •  LCD direct drive and control
  •  Low active and sleep mode power consumption, with full operation down to 0.5V
  •  CapSense fully integrated
  •  FS USB
  •  On chip EEPROM

Application Notes

Development Kits/Boards

  • The CY8CKIT-001 PSoC® Development Kit (DVK) provides a common development platform where you can prototype and evaluate different solutions using any one of the PSoC 1, PSoC 3, PSoC 4, or PSoC 5 architectures.

  • Cypress's PSoC programmable system-on-chip architecture gives you the freedom; to not only imagine revolutionary new products, but the capability to also get those products to market faster than anyone else. Explore PSoC 3's precision analog capabilities through the on board 20-bit Delta Sigma ADC used to measure voltage ranges between -30 V and 30 V.

  • The CY8CKIT-029 PSoC® LCD Segment Drive Expansion Board Kit allows you to evaluate PSoC's LCD drive capability using LCD segment component in Cypress's PSoC Creator™.
