M68AW031AM70N6T

Memory IC Overview

The M68AW031AM70N6T is a 256 Kbit (32K x 8) CMOS asynchronous SRAM manufactured by STMicroelectronics. It operates on a single 2.7 to 3.6V supply and features fully static operation without external clocks. The device provides equal cycle and access times of 70 ns. It includes an automatic power-down feature that reduces consumption by over 99% when deselected. Data retention is supported at VCC down to 1.5V. The component is housed in a TSOP28 package with standard pinout.

Memory IC Feature Summary

• Features automatic power-down mode to minimize standby current consumption when the chip enable signal is de-asserted.
• Supports low voltage data retention, maintaining memory content at supply voltages as low as 1.5V.
• Utilizes tri-state common I/O lines for efficient bus interfacing and high-speed read/write cycles.

Memory IC Applications

• Embedded systems requiring non-volatile-like data storage with fast random access.
• Cache memory buffers in microcontroller-based designs.
• Industrial control units needing reliable static RAM within specific temperature ranges.

Memory IC Procurement Notes

Verify the ordering suffix N6T corresponds to the TSOP28 package, -40 to 85 °C temperature range, and tape-and-reel shipping format. Confirm RoHS compliance and ECOPACK specifications during sourcing. Ensure the supplier provides official datasheets matching the M68AW031A series documentation.

Memory IC Selection Notes

Select this part for applications requiring 32K x 8 organization with 70 ns access speed. It is suitable for designs operating between 2.7V and 3.6V. Consider the TSOP28 package dimensions if space constraints exist. Verify compatibility with system logic levels and timing requirements for address and control signals.

Memory IC Part Context

This component belongs to the M68AW031A family of 256 Kbit asynchronous SRAMs from STMicroelectronics. The family offers various package options including SO28 and TSOP28 with different pinouts. It targets general-purpose memory applications where low power and fast access are critical.

Memory IC Replacement Considerations

Check for other M68AW031A variants with different speed grades or packages. Verify electrical compatibility before substituting with similar 256 Kbit SRAMs from other manufacturers.

Memory IC FAQ

What is the minimum supply voltage for data retention?

The device supports data retention at a supply voltage (VDR) of 1.5V when deselected.

How does the automatic power-down feature work?

When the Chip Enable (E) input is de-asserted (High), the device enters an automatic standby mode, reducing power consumption significantly.
