Good quality, standard specs

The chip works as advertised with 25ns access time. I used it in a custom controller project. One star off only because the packaging could have been more anti-static focused, but the component itself is fine.

Exactly what I needed

No issues with installation. The 28-pin DIP footprint is standard and fits easily into sockets. Data retention looks solid so far in my test rig.

Perfect replacement for old arcade board

Needed this specific SRAM chip to repair a vintage arcade logic board. The pinout matched perfectly and the device is functioning correctly after installation. Shipping was faster than expected.

Works for legacy systems

Bought a batch for maintaining some older medical diagnostic equipment (non-critical subsystems). All 10 units tested good. Price is a bit high due to scarcity, but that's market reality.

Genuine IDT component

Verified the markings under a microscope; these are genuine IDT chips, not remarked clones. Essential for maintaining the integrity of legacy industrial equipment repairs.

Fast shipping and well packed

Arrived in anti-static foam within two days. Tested immediately on my breadboard setup and read/write cycles are stable. Great seller for hard-to-find parallel SRAM.

5 FAQ

Q: Do you provide a datasheet with the shipment?

A: We do not include physical paper datasheets to reduce waste, but a digital PDF version of the official IDT datasheet is available for download on our product page or can be emailed upon request.

Q: Does this come in surface mount (SOP) package?

A: This specific listing is for the 28-pin DIP (Dual Inline Package) through-hole version only. We do have SOP versions available in a separate listing if you search for the suffix 'SO' instead of 'PG'.

Q: Is this chip compatible with 3.3V logic levels?

A: No, the 71256SA25TPG is designed for 5V operation. Using it with 3.3V logic may result in unreliable performance or failure to recognize high signals. Please check your circuit voltage requirements.

Q: What is the country of origin for these components?

A: These components are manufactured by IDT, which has fabrication facilities in multiple countries including the USA and Malaysia. The specific batch origin may vary, but all meet original manufacturer quality standards.

Q: Can I use this to upgrade the memory in a modern PC?

A: No, this is a legacy parallel SRAM chip intended for embedded systems, industrial controllers, or retro computing projects. It is not compatible with modern PC motherboard architectures which use DDR SDRAM.
