Product details

10 ns access time — timing margin for legacy bus

This is a 1Mbit asynchronous SRAM organized as 256K x 4. Supply range is 4.5V to 5.5V — a true 5V part.

28-SOJ package — footprint and rework

The package is 28-SOJ, a 0.400-inch wide, 10.16 mm body, J-lead surface-mount package. The J-lead footprint is different from a TSOP-28 — the pads are under the body, not on the perimeter. Rework requires a hot-air nozzle that heats the whole body; individual pin soldering is impractical because the leads are hidden under the package.

Frequently asked questions

What is the replacement for the CY7C106D-10VXIT?

Infineon has not published a direct replacement or successor for this part. If a pin-compatible 5V asynchronous SRAM is needed, the closest functional match would be another 256K x 4, 10 ns, 28-SOJ device from a different manufacturer — but the pinout must be verified against the original Cypress/Infineon footprint.

What package does the CY7C106D-10VXIT use?

28-SOJ (Small Outline J-lead), 0.400-inch body width, 10.16 mm. Surface-mount, J-bend leads on 1.27 mm pitch.

Is the CY7C106D-10VXIT RoHS compliant?

The 'T' suffix in the order code indicates Tape & Reel packaging. The CY7C106D-10VXIT is the RoHS-compliant version of the CY7C106D-10VXI — the 'VXI' suffix typically denotes the non-RoHS variant. Confirm with the datasheet for full material declaration.
