Product details

Industrial temperature and 44-SOJ package — rework and environment

The CY7C1021D-10VXI: The 44-SOJ package (0.400" body width, 10.16 mm) is a surface-mount J-lead form — reworkable with hot air if you keep the nozzle off the plastic body, and the J-bend gives a visual solder-joint inspection that a QFN hides.

Listed as Active by the manufacturer. The base product number CY7C1021 covers a family of speed and package variants; if availability ever tightens, a pin-compatible sibling in the same 44-SOJ footprint is the natural cross-reference.

Frequently asked questions

Is CY7C1021D-10VXI compatible with a 3.3V supply?

Running it at 3.3 V is outside the rated operating conditions; a 3.3V asynchronous SRAM would need a different part number in the CY7C1021 family or a separate 3.3V memory device.

What is the difference between CY7C1021D-10VXI and CY7C1021D-10VI?

The suffix VXI indicates a lead-free / RoHS-compliant finish, while the 10VI suffix typically marks a tin-lead (eutectic) finish. Both share the same 10 ns speed grade, 1 Mbit density, 44-SOJ package, and industrial temperature range. The VXI variant is the current standard for new designs requiring RoHS compliance.
