ST202CDR datasheet by STMicroelectronics

ST202CDR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the ST202CDR?
  The recommended operating voltage range for the ST202CDR is 2.7V to 5.5V.
• How do I ensure reliable data retention in the ST202CDR?
  To ensure reliable data retention, it is recommended to follow the recommended storage conditions, avoid exposure to extreme temperatures, and use a suitable capacitor value for the VCC pin.
• What is the maximum clock frequency supported by the ST202CDR?
  The maximum clock frequency supported by the ST202CDR is 400 kHz.
• Can I use the ST202CDR in a noisy environment?
  Yes, the ST202CDR has built-in noise filtering and is designed to operate in noisy environments. However, it's still recommended to follow proper PCB design and layout guidelines to minimize noise interference.
• How do I handle the HOLD pin in the ST202CDR?
  The HOLD pin is used to pause the serial clock and allow the microcontroller to service other tasks. It's recommended to tie the HOLD pin to VCC or use an external pull-up resistor to ensure proper operation.
