FT24C04A-UTG-B

Overview

The FT24C04A-UTG-B is a 4K-bit (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I2C-compatible two-wire interface with a maximum clock frequency of 1 MHz at 5V and 400 kHz at lower voltages. The device operates on a supply voltage range of 1.8V to 5.5V and supports industrial temperatures from -40°C to 85°C. It utilizes a TSSOP-8 package and includes hardware write protection via the WP pin.

Feature Summary

• Supports standard I2C bus modes for reliable data transmission
• Includes hardware write protection to secure memory arrays
• Features low power consumption with standby current under 1µA
• Provides high endurance with typical one million write cycles

Applications

• Industrial control systems requiring non-volatile storage
• Consumer electronics utilizing low voltage operation
• Embedded devices needing compact surface-mount packaging

Procurement Notes

Verify that the specific ordering suffix matches the required package type, as the 'U' indicates temperature range and 'T' denotes tape and reel packaging. Confirm RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the vendor provides original manufacturer documentation to validate authenticity before procurement.

Selection Notes

Select this component when a 4K-bit capacity is sufficient for application requirements. Consider the TSSOP-8 package dimensions against available PCB space constraints. Evaluate the 1.8V to 5.5V operating range compatibility with the system's power supply rails. Verify that the I2C bus speed requirements align with the specified clock frequencies.

Part Context

This part belongs to the FT24C04A/08A/16A series of serial EEPROMs. These devices share common architectural features including the two-wire interface and self-timed write cycles. The series offers various package options such as DIP, SOP, DFN, and SOT-23 to accommodate different design needs while maintaining consistent electrical performance characteristics across the family.

FAQ

How does the Write Protect (WP) pin function?

Connecting the WP pin to VCC disables all programming functions, protecting the memory array. Leaving it unconnected or connecting it to ground allows normal read and write operations.

What is the page write capability of this device?

The device supports a 16-byte page write mode, allowing up to 16 bytes to be programmed in a single sequence without issuing a STOP condition between each byte.
