M93C56-RDW6TP

Memory IC Overview

The M93C56-RDW6TP is a 2 kbit (256 x 8 or 128 x 16) Microwire serial access EEPROM manufactured by STMicroelectronics. It operates within a supply voltage range of 1.8 V to 5.5 V and supports clock frequencies up to 2 MHz. The device features byte and page write cycles completed within 5 ms, enhanced ESD protection rated at 4000 V human body model, and data retention exceeding 200 years. It is housed in an 8-pin TSSOP package.

Memory IC Feature Summary

• Microwire interface compatible with industry standard bus
• Dual memory organization selectable via ORG pin
• Self-timed erase and write cycle operations
• READY/BUSY status signal for programming monitoring

Memory IC Applications

• Configuration storage in embedded systems
• Parameter setting retention in industrial controllers
• Device identification data storage

Memory IC Procurement Notes

Verify the specific suffix 'RDW6TP' against official STMicroelectronics documentation to confirm package type, tape and reel specifications, and environmental compliance details. Ensure the ordering information matches the required voltage range and temperature grade for your application design.

Memory IC Selection Notes

Select this component when a low-voltage operation down to 1.8 V is required alongside standard 5 V compatibility. The Microwire interface minimizes pin count compared to SPI alternatives. Consider the TSSOP-8 package dimensions for PCB layout constraints and verify that the 2 MHz maximum clock frequency meets system timing requirements.

Memory IC Part Context

This part belongs to the M93Cx6 family of electrically erasable programmable read-only memories. The family includes variants with capacities ranging from 1 Kbit to 16 Kbit. The '-R' designation indicates support for the lower 1.8 V supply voltage threshold, distinguishing it from the '-W' variant which starts at 2.5 V.
