24LC21A/P** is a 2Kb I²C™ Serial EEPROM manufactured by **Microchip Technology**.

The 24LC21A/P is a 2Kb I²C™ Serial EEPROM manufactured by Microchip Technology. Below are its key specifications, descriptions, and features:

Specifications:

  • Memory Size: 2 Kbit (256 x 8 bits)
  • Interface: I²C™ (2-wire serial interface)
  • Operating Voltage: 1.7V to 5.5V
  • Write Cycle Endurance: 1,000,000 cycles
  • Data Retention: >200 years
  • Maximum Clock Frequency: 400 kHz (I²C Fast Mode)
  • Page Write Buffer: 8 bytes
  • Operating Temperature Range: -40°C to +85°C
  • Package: 8-pin PDIP (Plastic Dual In-line Package)

Descriptions:

  • The 24LC21A/P is a low-power, byte-addressable EEPROM with I²C interface.
  • It supports software write protection, allowing partial or full memory protection.
  • Designed for reliable non-volatile data storage in embedded systems.

Features:

  • Low-Power Operation:
  • Standby current: <1 µA (typical)
  • Active read current: 1 mA (typical)
  • Hardware Write-Protect Pin (WP):
  • Prevents accidental writes when enabled.
  • Self-Timed Write Cycle:
  • Includes auto-erase before write.
  • Schmitt Trigger Inputs:
  • Improves noise immunity.
  • Industrial Temperature Range:
  • Suitable for harsh environments.

This device is commonly used in applications requiring small, reliable, and low-power non-volatile memory, such as industrial controls, consumer electronics, and automotive systems.
