N24S64C4DYT3G

Memory IC Overview

The N24S64C4DYT3G is a 64 Kb I2C CMOS Serial EEPROM organized as 8,192 words of 8 bits. It supports Standard (100 kHz), Fast (400 kHz), and Fast-Plus (1 MHz) I2C protocols with a supply voltage range of 1.7 V to 5.5 V. The device includes a 32-byte page write buffer, a 128-bit factory-set read-only Unique ID, and a 32-byte Secure Data Page that can be permanently locked. A Device Configuration Register allows user-programmable addressing for up to eight devices on the same bus. It features software write protection for the entire array and operates within an industrial temperature range of −40°C to +85°C.

Memory IC Procurement Notes

Verify the specific ordering suffix C4DYT3G matches the required package type and shipping configuration. Confirm the industrial temperature range and RoHS compliance requirements align with system specifications. Ensure UV exposure precautions are observed during handling and assembly due to WLCSP packaging sensitivity.

Memory IC Selection Notes

Select this component when a compact serial EEPROM with hardware security features is required. The programmable address bits allow efficient bus utilization in multi-device designs. Verify that the I2C clock speed and supply voltage levels of the host controller are compatible with the device's operating conditions.

Memory IC Part Context

This part belongs to the N24S64 family of 64 Kb serial EEPROMs from onsemi. It utilizes a 4-ball WLCSP package for space-constrained applications. The device integrates advanced security features like a lockable secure page and unique identification, distinguishing it from standard EEPROMs lacking these capabilities.

Memory IC Replacement Considerations

Check for pin-compatible alternatives within the same memory density class. Verify that substitute parts support the same I2C protocol speeds and voltage ranges. Ensure replacement components offer equivalent security features if the lockable page or unique ID is critical to the design.
