25C128P** is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by **Chip Storage Inc.

The 25C128P is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Chip Storage Inc. (CSI). Below are its key specifications, descriptions, and features:

Specifications:

  • Memory Size: 128 Kbit (16 K x 8 bits)
  • Interface: SPI (Serial Peripheral Interface)
  • Operating Voltage: 2.5V – 5.5V
  • Operating Temperature Range: -40°C to +85°C
  • Write Cycle Endurance: 1,000,000 cycles (typical)
  • Data Retention: 100 years (minimum)
  • Page Size: 64 bytes
  • Clock Frequency: Up to 10 MHz (5V operation)
  • Package Options: 8-pin DIP, SOIC, TSSOP

Descriptions:

  • The 25C128P is a non-volatile memory device that supports byte-level and page-level write operations.
  • It features a SPI-compatible bus for easy interfacing with microcontrollers.
  • Includes a write-protect pin (WP) to prevent accidental writes.
  • Supports sequential read for faster data access.

Features:

  • Low Power Consumption:
  • Active Read Current: 3 mA (max)
  • Standby Current: 5 µA (max)
  • Hardware Write Protection: WP pin for block protection.
  • Self-Timed Write Cycle: Automatic erase and program cycle.
  • Built-in Error Detection: Status register for write-in-progress monitoring.
  • Industrial-Grade Reliability: High endurance and long data retention.

This EEPROM is commonly used in embedded systems, automotive electronics, and consumer devices for storing configuration data, calibration settings, and firmware updates.
