FT24C04A-USR-B

Overview

The FT24C04A-USR-B is a 4Kb (512 x 8) serial EEPROM manufactured by Fremont Micro Devices Ltd. It features an I2C-compatible two-wire serial interface with a maximum clock frequency of 1 MHz at 5V and 400 kHz at lower voltages. The device operates within a supply voltage range of 1.8V to 5.5V and supports industrial temperatures from -40°C to 85°C. It utilizes an 8-pin SOP package in a RoHS-compliant tube.

Feature Summary

• Supports 16-byte page write mode with partial page write capability.
• Includes a hardware write protect pin for data security.
• Features Schmitt trigger inputs for noise protection.

Applications

• Industrial control systems
• Consumer electronics
• Automotive applications

Procurement Notes

Verify the specific ordering suffix 'USR-B' corresponds to the SOP-8 package, RoHS compliance, and tube packaging format as defined in the manufacturer's order code table. Confirm that the component meets the required industrial temperature range specifications for your intended deployment environment.

Selection Notes

Select this component when a 4Kb non-volatile memory solution is required with standard I2C connectivity. Ensure the design accommodates the 1.8V to 5.5V operating voltage range and the 8-pin SOP footprint. Consider the 5ms self-timed write cycle duration for timing constraints.

Part Context

This part belongs to the FT24C04A/08A/16A series of Two-Wire Serial EEPROMs. These devices are fabricated using advanced CMOS technology designed for low power consumption. The series shares common architectural features including the 2-wire serial interface and similar electrical characteristics across different memory densities.

FAQ

How many devices can be connected on the same bus?

Up to four FT24C04A devices can be wired-OR on the same 2-wire bus using the A2 and A1 chip select address pins.

What is the function of the WP pin?

The Write Protect (WP) pin protects the entire EEPROM array from programming operations. Programming is disabled when WP is connected to VCC or VIH.
