• Self-timed internal programming cycle
• 16-byte page write capability

Applications

• Industrial control systems
• Consumer electronics configuration storage
• Automotive data logging

Procurement Notes

Verify the specific ordering suffix 'ESR-B' against official datasheets, as standard listings typically use 'USR-B'. Confirm RoHS compliance status and ensure the selected package matches the required PCB footprint for SOP-8 components.

Selection Notes

Select this component for designs requiring low standby current and robust noise immunity through Schmitt trigger inputs. Ensure the application supports the specified voltage range and that the bus architecture accommodates up to four devices on the same serial line.

Part Context

This part belongs to the FT24C04A/08A/16A series of serial EEPROMs. These devices are fabricated using advanced CMOS technology to minimize power consumption while maintaining high reliability and long data retention characteristics suitable for non-volatile memory applications.

FAQ

How many devices can be connected to the same bus?

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

What is the function of the WP pin?

The Write Protect (WP) pin disables all programming functions when connected to VIH or VCC, protecting the memory array from accidental writes.
