24FC01T-E/OT36KVAO

Memory IC Overview

The Microchip Technology 24FC01T-E/OT36KVAO is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-wire I2C compatible serial interface. It supports a maximum clock frequency of 1 MHz and operates on a single supply voltage ranging from 1.7 V to 5.5 V. The device utilizes low-power CMOS technology with a maximum active read current of 1 mA and standby current of 3 µA in the extended temperature range. It is housed in a 5-lead SOT-23 package, qualified under AEC-Q100 standards for automotive applications, and rated for an operating temperature range of -40°C to +125°C.

Memory IC Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for reliability in demanding environments.
• Integrated hardware write-protect capability via the WP pin to secure memory data against unauthorized modifications.
• Enhanced noise immunity provided by Schmitt trigger inputs and output slope control mechanisms.
• Supports page write operations utilizing an 8-byte buffer to optimize bus throughput efficiency.

Memory IC Applications

• Automotive electronic systems requiring durable non-volatile data storage
• Industrial control units operating within extended temperature ranges
• Consumer devices needing compact surface-mount memory solutions

Memory IC Procurement Notes

Verify that the specific suffix '36KVAO' aligns with your manufacturing requirements, as standard datasheets may not explicitly detail custom ordering codes. Confirm the package type matches your PCB footprint design. Ensure the component meets RoHS compliance standards for your region. Validate the AEC-Q100 qualification status if deploying in automotive contexts. Cross-reference the traceability code with your quality assurance protocols before finalizing orders.

Memory IC Selection Notes

Select this component when a small 5-lead SOT-23 package is required for space-constrained designs. Choose this part over the 24LC01B variant if operation below 2.5 V is necessary, as it supports voltages down to 1.7 V. Opt for this model instead of the 24AA01 when higher bus speeds up to 1 MHz are needed at full voltage ranges. Consider this device for applications demanding high endurance and long-term data retention capabilities.

Memory IC Part Context

This EEPROM belongs to the 24XX01 family, which includes the 24AA01 and 24LC01B variants. While sharing similar architectural features, the 24FC01 series is distinguished by its support for 1 MHz clock frequencies and lower minimum operating voltages. The family offers various package options, including SOIC, MSOP, and SOT-23, catering to diverse board layout requirements across industrial and automotive sectors.

Memory IC Replacement Considerations

Direct substitutes include other 24FC01 variants with different packages or temperature grades, such as 24FC01-E/MS or 24FC01-I/OT. Verify compatibility with existing firmware addressing schemes when swapping between package types. Ensure voltage levels remain within the 1.7 V to 5.5 V range for all replacement options.

Memory IC FAQ

How does the Write-Protect (WP) pin function?

Connecting the WP pin to VCC inhibits all write operations, protecting the entire memory array. Connecting it to VSS enables normal read and write access.

What is the maximum page write size?

The device features an 8-byte page write buffer, allowing up to eight bytes to be written in a single transaction without generating a Stop condition.

Is acknowledge polling supported?

Yes, the device does not generate acknowledge signals during internal write cycles, allowing the master to poll for completion and maximize bus throughput.
