M95320-DRDW3TP/K

Memory IC Overview

The M95320-DRDW3TP/K is a 32 Kbit (4 Kbyte) serial electrically erasable programmable read-only memory (EEPROM) device manufactured by STMicroelectronics. It operates within a supply voltage range of 1.7 V to 5.5 V and supports SPI bus interfaces with clock frequencies up to 10 MHz for voltages above 2.5 V. The memory array is organized as 4096 x 8 bits, structured into 128 pages of 32 bytes each. The component is housed in an 8-pin TSSOP package and is designed for surface mount installation. It features Schmitt trigger inputs for noise filtering and includes an embedded Error Correction Code logic to enhance data integrity.

Memory IC Feature Summary

• Compliant with AEC-Q100 Grade 2 automotive reliability standards
• Includes an additional lockable identification page for storing sensitive parameters
• Supports software write protection by quarter block and hardware write protection for the entire memory array

Memory IC Applications

• Automotive electronic systems requiring durable non-volatile storage
• Industrial control units operating under extended temperature conditions
• Embedded applications needing secure parameter retention with error correction

Memory IC Procurement Notes

Verify that the specific suffix DRDW3TP/K corresponds to the TSSOP-8 package and the intended temperature grade. Confirm the AEC-Q100 Grade 2 qualification status matches the application requirements. Ensure the SPI interface timing specifications align with the system controller capabilities. Check for RoHS compliance and ECOPACK2 halogen-free packaging details before finalizing procurement.

Memory IC Selection Notes

Select this component when an automotive-grade EEPROM with high-speed SPI access and enhanced data integrity via ECC is required. It is suitable for designs needing byte-alterable memory with flexible write protection schemes. Consider the 1.7 V to 5.5 V operating range for compatibility with various power domains. The TSSOP-8 package is appropriate for space-constrained surface-mount layouts.

Memory IC Part Context

This part belongs to the M95320-A125 series of automotive serial EEPROMs. It shares core architectural features with other members of the family, such as the M95320-DRE, but differs in specific package options and temperature ranges. The device utilizes advanced true EEPROM technology to ensure long-term data retention and high write cycle endurance across varying environmental conditions.

Memory IC Replacement Considerations

The M95320-DRE is a related active device offering similar 32-Kbit capacity and SPI interface. Verify if the DRE variant's specific temperature range or package availability meets the design constraints. Both parts share the same memory organization and protection features, ensuring functional compatibility in many applications.
