S-93C56BR0I-J8T1G

Memory IC Overview

The S-93C56BR0I-J8T1G is a 2 kbit (128 x 16) serial EEPROM from ABLIC Inc., utilizing the Microwire 3-wire interface. It operates within a voltage range of 1.8 V to 5.5 V for reading and 2.7 V to 5.5 V for writing, with a maximum clock frequency of 2 MHz at higher voltages. The device features an SOP-8 package, supports sequential read operations, and includes write protection during low power supply conditions. It offers 1 million cycle endurance per word and retains data for up to 100 years at 25°C or 20 years at 85°C.

Memory IC Feature Summary

• Supports sequential read operations with automatic address incrementation in 16-bit blocks.
• Includes built-in detection to cancel write instructions and set write disable state during low power supply voltage.
• Features a clock pulse monitoring circuit that cancels erroneous write instructions caused by noise pulses or double counting.
• Provides a verify operation function to monitor write completion status via the DO pin output.

Memory IC Applications

• Consumer electronics
• Office equipment
• Communications devices

Memory IC Procurement Notes

Verify the specific ordering suffix against the manufacturer's product name structure to confirm environmental compliance, such as lead-free and halogen-free status. Confirm the package type matches the required SOP-8 configuration. Ensure the design accounts for the recommended operating conditions regarding power supply voltage ranges for both read and write operations.

Memory IC Selection Notes

Select this component for applications requiring low current consumption and wide operating voltage compatibility. Consider the Microwire interface requirements and ensure the system can handle the specified clock frequencies. Evaluate the need for write protection features and data retention specifications relative to the intended ambient temperature range.
