24C02C-I/ST

Memory IC Overview

The Microchip Technology 24C02C-I/ST is a 2-kbit (256 x 8) serial EEPROM featuring an I2C interface. It operates within a supply voltage range of 4.5 V to 5.5 V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, with maximum active read current of 3 mA and standby current of 5 μA. It offers data retention of 200 years and endurance of one million write cycles. The component is housed in an 8-pin TSSOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports standard I2C bus protocol with cascading capability for up to eight devices on the same bus.
• Features Schmitt trigger inputs on SDA and SCL lines to suppress noise and ensure signal integrity.
• Includes output slope control mechanisms designed to minimize ground bounce during switching operations.
• Provides hardware write protection via dedicated pin configuration to prevent accidental data modification.

Memory IC Applications

• Non-volatile data storage in industrial control systems requiring reliable parameter retention.
• Configuration memory for embedded microcontroller applications operating at standard logic voltages.
• Calibration data storage for sensor interfaces and measurement instrumentation.
• Device identification and serial number storage in consumer electronics assemblies.

Memory IC Procurement Notes

Verify the specific suffix 'I/ST' corresponds to the industrial temperature grade (-40°C to +85°C) and TSSOP-8 packaging. Confirm that the required supply voltage aligns with the 4.5V to 5.5V operational range, as this variant does not support lower voltage operation. Ensure compatibility with the target system's I2C pull-up resistor values and address configuration requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a standard 5V supply environment is present and I2C connectivity is required. It is suitable for designs needing robust noise immunity through Schmitt triggers and high endurance. Consider alternative low-voltage variants if the system operates below 4.5V. Verify that the TSSOP-8 footprint matches the PCB layout constraints and that the thermal dissipation capabilities are sufficient for the intended application density.

Memory IC Part Context

This part belongs to the Microchip 24xx02 family of serial EEPROMs, which provides compact non-volatile storage solutions. The family shares common I2C interface protocols but varies in voltage ranges and package options. The 24C02C series specifically targets standard voltage applications, distinguishing it from the AT24C02 series which often supports extended low-voltage operation down to 1.7V or 1.8V depending on the specific sub-model.

Memory IC Replacement Considerations

Direct substitutes include other 24C02 variants from Microchip such as 24C02C-I/SN (SOIC-8) or 24C02C-I/MS (MSOP-8), provided the package change is acceptable. Cross-manufacturer replacements like the AT24C02 require verification of voltage compatibility, as some AT24C02 versions support lower voltages than the 24C02C-I/ST.
