Product Introduction

Overview

The CAT25128VI-GD is a 128-Kb Serial CMOS EEPROM device produced by onsemi. This device is internally organized as 16Kx8 bits and features a 64-byte page write buffer. It supports the Serial Peripheral Interface (SPI) protocol and is enabled through a Chip Select (CS) input. The device includes necessary bus signals such as clock input (SCK), data input (SI), and data output (SO) lines, along with a HOLD input to pause any serial communication. The CAT25128VI-GD is designed for high reliability applications with on-chip ECC (Error Correction Code) and offers both hardware and software write protection.

Q & A

  1. What is the memory organization of the CAT25128VI-GD? The device is internally organized as 16Kx8 bits.
  2. What is the maximum clock frequency supported by the CAT25128VI-GD? The device supports up to 20 MHz clock frequency.
  3. What are the supply voltage range and temperature range for the CAT25128VI-GD? The supply voltage range is 1.8 V to 5.5 V, and the temperature range is -40°C to +125°C.
  4. How many program/erase cycles does the CAT25128VI-GD support? The device supports up to 1,000,000 program/erase cycles.
  5. What is the data retention period of the CAT25128VI-GD? The data retention period is 100 years.
  6. Does the CAT25128VI-GD have any write protection features? Yes, it features both hardware and software write protection, including block write protection and an additional identification page with permanent write protection.
  7. How does the HOLD input function on the CAT25128VI-GD? The HOLD input can be used to pause communication between the host and the CAT25128 device by taking the HOLD pin low while SCK is low.
  8. What is the purpose of the on-chip ECC in the CAT25128VI-GD? The on-chip ECC (Error Correction Code) enhances the device's reliability by correcting errors that may occur during data storage and retrieval.
  9. Can the CAT25128VI-GD be used in high-temperature environments? Yes, the device operates over a temperature range of -40°C to +125°C.
  10. How is the device powered up and reset? The device incorporates Power-On Reset (POR) circuitry, ensuring it powers up in a write disable state and standby mode, and resets when VCC drops below the POR trigger level.
