24C02C/P

Memory IC Overview

The Microchip Technology 24C02C/P is a 2K-bit (256 x 8) serial EEPROM utilizing an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 4.5V to 5.5V and supports clock frequencies up to 400 kHz. The device features a typical write cycle time of 1 ms, hardware write protection for the upper half of the array, and a 16-byte page write buffer. It is housed in an 8-lead PDIP package and designed for industrial temperature ranges.

Memory IC Feature Summary

• Supports cascading up to eight devices on a single bus using hardware address pins
• Includes Schmitt trigger inputs and output slope control for noise suppression
• Features self-timed erase/write cycles with automatic acknowledge polling capability

Memory IC Applications

• Industrial equipment requiring non-volatile data storage
• Consumer electronics needing configuration parameter retention
• Automotive systems operating within extended temperature limits

Memory IC Procurement Notes

Verify the specific suffix 'P' corresponds to the 8-lead PDIP package type. Confirm the temperature grade matches project requirements, as the datasheet distinguishes between Industrial (I) and Automotive (E) variants. Ensure the design accommodates the specified 4.5V to 5.5V supply range and pull-up resistor requirements for the I²C bus lines.

Memory IC Selection Notes

Select this component when a standard 5V supply environment requires robust noise immunity via Schmitt triggers. The 8-pin PDIP format is suitable for through-hole prototyping or manufacturing. Consider the 16-byte page buffer for efficient sequential writes. Verify that the maximum 400 kHz clock speed aligns with the master controller's capabilities.

Memory IC Part Context

This part belongs to the 24C02C family of 2K-bit serial EEPROMs manufactured by Microchip Technology. The family offers various package options including SOIC, TSSOP, DFN, and MSOP. The 24C02C series is characterized by low power consumption and high endurance, making it a standard choice for general-purpose memory applications across multiple industries.

Memory IC FAQ

How does the hardware write protection function?

Tying the WP pin to VCC enables hardware write protection for the upper half of the memory array (addresses 0x80 to 0xFF). Tying it to VSS disables protection for all addresses.

What is the mechanism for end-of-write detection?

The device does not generate an Acknowledge signal during the internal write cycle. Masters can use ACK polling by sending a Start condition and the Write command byte to detect when the cycle is complete.
