24FC08-I/ST

Memory IC Overview

The Microchip Technology 24FC08-I/ST is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols, supporting clock frequencies up to 1 MHz across the full operating voltage range of 1.7V to 5.5V. The device utilizes low-power CMOS technology, ensuring standby current remains at or below 1 µA and active read current does not exceed 1 mA. It includes a 16-byte page write buffer for efficient data handling and offers hardware write protection via the WP pin.

Memory IC Feature Summary

• Supports high-speed 1 MHz I2C communication across the entire 1.7V to 5.5V supply voltage range
• Includes a 16-byte page write buffer to optimize sequential data writing operations
• Provides hardware write protection through the dedicated WP pin to prevent unauthorized memory modifications
• Features Schmitt trigger inputs and output slope control to suppress noise and eliminate ground bounce

Memory IC Applications

• Low-power personal communication devices requiring non-volatile data storage
• Data acquisition systems needing reliable parameter retention
• Industrial control applications utilizing I2C bus architectures
• Embedded systems requiring hardware-level write protection for critical configuration data

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the TSSOP-8 package type required for your design. Confirm the temperature grade 'I' meets the operational requirements of -40°C to +85°C. Ensure the voltage supply aligns with the 1.7V to 5.5V specification to guarantee the advertised 1 MHz clock frequency performance. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Memory IC Selection Notes

Select this component when a balance between high-speed 1 MHz operation and ultra-low voltage capability down to 1.7V is necessary. It is suitable for designs where power consumption must be minimized during both active and standby states. Consider this part over standard variants if hardware write protection is required without software overhead. Ensure the application environment stays within the industrial temperature range specified for the 'I' suffix.

Memory IC Part Context

This device belongs to the 24XX08 family of serial EEPROMs from Microchip Technology. It shares architectural similarities with the 24AA08 and 24LC08B but distinguishes itself by supporting higher clock speeds at lower voltages. The family provides various package options including DFN, MSOP, PDIP, SOIC, and TSSOP to accommodate different PCB layout constraints and assembly methods.

Memory IC Replacement Considerations

Direct functional substitutes within the same family include the 24AA08 and 24LC08B, though their electrical characteristics differ regarding maximum clock frequency and minimum operating voltage. Verify compatibility before swapping, as the 24LC08B requires a minimum of 2.5V and supports only 400 kHz, while the 24AA08 limits speed to 100 kHz below 2.5V.
