FT24C04A-UTR-B

Overview

The FT24C04A-UTR-B is a 4K-bit (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It utilizes a standard two-wire I2C interface and operates within a supply voltage range of 1.8V to 5.5V. The device supports clock frequencies up to 1 MHz at 5V and 400 kHz at lower voltages, with a maximum write cycle time of 5 ms. It features hardware data protection via a Write Protect pin and is housed in an 8-pin TSSOP package.

Feature Summary

• Supports 16-byte page write operations with partial page write capability.
• Includes a dedicated hardware Write Protect pin for array security.
• Features Schmitt trigger inputs with filtering for noise immunity.
• Provides automatic erase before write functionality.

Applications

• Low power embedded systems requiring non-volatile storage
• Industrial control units operating in wide temperature ranges
• Consumer electronics utilizing I2C bus architectures

Procurement Notes

Verify the specific ordering suffix 'B' corresponds to tube packaging rather than tape and reel. Confirm RoHS compliance status matches project requirements. Ensure the selected package variant aligns with PCB footprint specifications. Cross-reference datasheet revision dates against manufacturing batches.

Selection Notes

Select this component when a 4K-bit capacity is required alongside a compact surface-mount form factor. The TSSOP package offers a smaller footprint compared to DIP or SOP alternatives. Verify that the system design accommodates the specific address pin configuration unique to the 4K model.

Part Context

This part belongs to the FT24C04A/08A/16A series of Two-Wire Serial EEPROMs. It shares core electrical characteristics and interface protocols with other capacities in the family, differing primarily in memory organization and available chip select address pins.

FAQ

How many devices can be addressed on a single I2C bus?

Four FT24C04A devices can be wired-OR on the same bus using the A2 and A1 address pins.

What is the function of the WP pin?

The Write Protect pin disables all programming functions when connected to VIH, while read operations remain unaffected.
