Product details

The CY7C1021CV33-10VC: The 64K x 16 organization means a single chip provides a 16-bit wide data path, so a 16-bit MCU or DSP can read or write a full word in one bus transaction without byte-lane muxing.

Infineon (formerly Cypress) lists the CY7C1021CV33-10VC as Obsolete. This means the part is no longer in production and cannot be ordered through the factory channel.

44-SOJ package — footprint and reflow notes

The part comes in a 44-SOJ (Small-Outline J-lead) package, 0.400" body width (10.16 mm). The J-bend leads are surface-mount but require a specific solder-paste stencil aperture and reflow profile — the J-lead heel fillet is critical for joint reliability. The package ships in Tube (the listed shipping medium).
