FT93C56A-ISR-B

Overview

The FT93C56A-ISR-B is a non-volatile EEPROM memory IC manufactured by Fremont Micro Devices Ltd. It features a storage capacity of 2Kbit, organized as 256 x 8 or 128 x 16 bits. The device utilizes a 3-wire serial interface with a maximum clock frequency of 2 MHz. It operates within a supply voltage range of 4.5V to 5.5V and supports through-hole mounting in an 8-SOP package. The component is designed for industrial temperature ranges, ensuring reliable data retention.

Feature Summary

• Supports 3-wire serial communication protocol for efficient data transfer
• Provides non-volatile data storage with high endurance capabilities
• Operates reliably across extended industrial temperature ranges

Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics needing configuration data retention
• Automotive modules for calibration data management

Procurement Notes

Verify the specific suffix 'ISR-B' corresponds to the 8-SOP package and 2MHz speed variant when sourcing. Confirm RoHS compliance status matches current regulatory requirements. Ensure the supplier provides official datasheets to validate electrical characteristics against design specifications before finalizing procurement orders.

Selection Notes

Select this component when a 2Kbit EEPROM with 3-wire interface is required in an SOP package. Compare against FT93C56A-UDR-B if DIP packaging is preferred instead of surface mount. Verify that the 2MHz clock speed meets system timing constraints. Check compatibility with existing microcontroller SPI/3-wire drivers.

Part Context

This part belongs to the FT93CxxA series of serial EEPROMs from Fremont Micro Devices. It shares functional similarities with other 93C-series devices but offers specific pinout and package variations. The ISR-B designation indicates the surface-mount SOP form factor, distinguishing it from through-hole DIP alternatives within the same product family.

Replacement Considerations

FT93C56A-UDR-B serves as a direct alternative offering identical electrical specifications in an 8-DIP package. Cross-reference pinouts to ensure mechanical compatibility during board redesigns. Verify that the substitute maintains the same 3-wire interface timing requirements.
