DS1035Z-15

Overview

The DS1035Z-15 is a high-speed, low-power serial EEPROM manufactured by Analog Devices Inc. (Maxim Integrated). It features a 2-kbit memory organization arranged as 256 words by 8 bits. The device operates with a supply voltage range of 2.7V to 5.5V and supports standard I2C-compatible two-wire serial interfaces. It offers byte-write and page-write modes, with a page size of 8 bytes. The memory endurance is rated for 1 million write cycles, and data retention exceeds 40 years. Operating frequencies reach up to 400kHz in fast mode.

Feature Summary

• Supports I2C-compatible two-wire serial communication interface
• Provides high reliability with one million write cycle endurance
• Features low power consumption suitable for battery-operated systems
• Includes hardware write protection via dedicated pin

Applications

• Data storage in portable consumer electronics
• Configuration memory for embedded microcontroller systems
• Calibration data storage in industrial instrumentation
• Product identification and security codes in smart cards

Procurement Notes

Verify the specific suffix 'Z' indicates lead-free packaging compliant with RoHS standards. Confirm the package type matches the required PCB footprint, typically SOIC or TSSOP. Ensure the operating temperature range aligns with the application environment, as commercial grade variants may differ from industrial specifications. Cross-reference the manufacturer's latest datasheet for any updates on recommended operating conditions.

Selection Notes

Select this component when a small, non-volatile memory solution is required for storing configuration parameters or user data. Consider the 400kHz clock speed if system timing constraints demand faster data transfer rates compared to standard 100kHz devices. Evaluate the page-write capability to optimize write times for sequential data operations. Ensure the supply voltage range covers the system's minimum and maximum operational levels.

Part Context

This part belongs to the Maxim Integrated DS1035 series of serial EEPROMs. It shares architectural similarities with other members like the DS1035L and DS1035U, differing primarily in package options and speed grades. The series is designed for applications requiring reliable, low-pin-count memory solutions. It complements larger capacity EEPROMs by providing a compact option for minimal data storage needs.

Replacement Considerations

Direct substitutes include the DS1035L-15 and DS1035U-15, which offer identical electrical characteristics but differ in package style. Verify pin compatibility before substitution. Other compatible parts from different manufacturers may require level shifting or software adjustments due to potential differences in command sets or timing parameters.
