M93C86-WDW6TP

Memory IC Overview

The M93C86-WDW6TP is a 16 Kbit (2048 x 8 or 1024 x 16) serial EEPROM from STMicroelectronics. It utilizes the MICROWIRE™ bus protocol for data access and supports dual organization modes selectable via the ORG pin. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports clock frequencies up to 2 MHz. It is housed in an 8-lead TSSOP package with a 0.65 mm pitch. The component ensures data integrity through enhanced ESD protection rated at 4000 V human body model and offers high endurance exceeding 4 million write cycles at 25°C, alongside a data retention capability of over 200 years.

Memory IC Feature Summary

• Supports dual memory organization configured by word (x16) or byte (x8) via the Organization Select input.
• Includes on-chip clock pulse counter to prevent instruction misalignment and erroneous data writing in noisy environments.
• Features READY/BUSY status output to monitor the completion of self-timed erase and write cycles.

Memory IC Applications

• Configuration storage in industrial control systems
• Parameter logging in automotive electronic modules
• Data backup in consumer electronics devices

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the required package type and environmental compliance grade. Confirm that the supply voltage requirements align with the system design, as the W-series variant specifies a minimum operating voltage of 2.5 V. Ensure compatibility with the MICROWIRE™ interface timing specifications during integration.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires simple three-wire serial communication without complex SPI command sets. The device is suitable for applications needing moderate density with high reliability standards. Consider the TSSOP8 package dimensions for PCB layout constraints and verify that the operating temperature range meets the environmental conditions of the target application.

Memory IC Part Context

This part belongs to the M93Cx6 family of serial EEPROMs, which includes variants with capacities ranging from 1 Kbit to 16 Kbit. The M93C86 represents the highest capacity in this specific series, providing 16 Kbits of electrically erasable programmable storage accessible via the industry-standard MICROWIRE™ bus protocol.

Memory IC Replacement Considerations

Compatible substitutes include other members of the M93Cx6 family such as M93C76 or M93C66, provided the memory density requirements are adjusted accordingly. Cross-referencing with M93C86-R variants is possible if lower voltage operation is required, though package and voltage differences must be evaluated.
