24C01C-I/P

Memory IC Overview

The Microchip Technology 24C01C-I/P is a 1K bit (128 x 8) serial electrically erasable PROM featuring a 2-wire I2C compatible interface. It operates on a single supply voltage ranging from 4.5V to 5.5V with a maximum clock frequency of 400 kHz and an access time of 900 ns. The device utilizes low-power CMOS technology, drawing a maximum read current of 1 mA and standby current of 5 µA. It supports page writes up to 16 bytes with a cycle time of 1 ms max. The component is housed in an 8-lead PDIP package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using hardware address inputs for expanded memory addressing.
• Includes Schmitt trigger inputs and output slope control to suppress noise spikes and eliminate ground bounce.
• Features self-timed erase/write cycles with acknowledge polling capability to maximize bus throughput.

Memory IC Applications

• Industrial systems requiring non-volatile data storage
• Embedded controllers needing configuration parameter retention
• Multi-device I2C bus architectures

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors before placing orders. Ensure the voltage supply aligns with the specified 4.5V to 5.5V operational range.

Memory IC Selection Notes

Select this component when a 1Kbit EEPROM with standard I2C compatibility is required. The Industrial temperature grade (-40°C to +85°C) suits general commercial and industrial environments. Consider alternative packages like SOIC or DFN if surface mount technology is preferred over through-hole mounting.

Memory IC Part Context

This part belongs to the 24C01C family of 1Kbit Serial EEPROMs manufactured by Microchip Technology. The 'I' designation indicates the Industrial temperature rating, while '/P' specifies the 8-lead Plastic Dual In-Line Package. This series provides reliable non-volatile storage solutions for various embedded applications.

Memory IC Replacement Considerations

Direct replacements include other 24C01C variants with different packages such as 24C01C-I/SN (SOIC) or 24C01C-E/MC (DFN). Verify pinout compatibility and ensure the substitute meets the same voltage and temperature specifications.

Memory IC FAQ

How many devices can be connected to a single I2C bus?

Up to eight 24C01C devices can be connected to the same bus by utilizing the three hardware address pins (A0, A1, A2) to create unique slave addresses.

What is the purpose of the Test pin?

The Test pin is utilized for manufacturing testing purposes only. In normal operation, it may be tied high, tied low, or left floating without affecting functionality.
