Product details

15 ns access time — bus timing fit

It uses a parallel interface and comes in a 36-pin SOJ surface-mount package.

SOJ-36 package — footprint and rework considerations

The device is supplied in a 36-BSOJ package (0.400" body width, 10.16 mm) with a surface-mount footprint. The SOJ form factor is a J-lead package commonly used for memory devices in the 1990s through early 2000s; it requires a standard reflow profile and is compatible with visual inspection. For rework, a hot-air station with a narrow nozzle works well; the J-leads are less prone to tombstoning than gull-wing packages.

Frequently asked questions

What is the access time of CY7C1049CV33-15VC?

This is a key parameter for bus timing: a 15 ns SRAM can typically interface with processors running at up to about 33 MHz without wait states, assuming the memory controller's address-to-data setup time is within budget.
