S-25C020A0I-J8T1G

Memory IC Overview

The S-25C020A0I-J8T1G is a 2 K-bit SPI serial EEPROM manufactured by ABLIC Inc. It features an operating voltage range of 1.6 V to 5.5 V for read operations and 1.7 V to 5.5 V for write operations. The device supports a maximum clock frequency of 5.0 MHz at voltages between 2.5 V and 5.5 V, with a page write capability of 16 bytes per page. It utilizes an 8-pin SOP (JEDEC) package and operates within a temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports software and hardware write protection with selectable block sizes
• Includes a low power supply voltage detection circuit to prevent malfunction during power drops
• Features a hold function to pause serial communications without deselecting the chip

Memory IC Applications

• Consumer electronics data storage
• Office equipment configuration memory
• Communications devices parameter retention

Memory IC Procurement Notes

Verify that the ordering suffix J8T1G corresponds to the 8-Pin SOP (JEDEC) package as specified in the datasheet. Confirm environmental compliance requirements, noting that products with the U suffix are Sn 100% and halogen-free, while G suffix specifications require direct manufacturer verification.

Memory IC Selection Notes

Select this component when a 2 K-bit capacity is required alongside SPI interface compatibility. Ensure the application voltage remains above 1.7 V for write operations. Consider the 16-byte page write size for efficiency and verify that the SOP-8 package fits the PCB layout constraints.

Memory IC Part Context

This part belongs to the S-25C010A/020A/040A series of SPI serial E2PROMs from ABLIC Inc. The series offers capacities of 1 K-bit, 2 K-bit, and 4 K-bit, sharing common electrical characteristics and instruction sets while differing in addressable memory depth and organization.

Memory IC FAQ

How does the device handle write operations during low power supply?

The device includes a built-in detection circuit that automatically cancels write operations and resets the Write Enable Latch if the power supply voltage drops below approximately 1.20 V.

What is the purpose of the HOLD pin?

The HOLD pin allows the user to pause serial communications without setting the device to the non-select status, keeping the chip selected while suspending data input and output.
