Product details

25 ns dual-port SRAM for shared-memory arbitration

The CY7C025E-25AXCT is a 128Kbit dual-port asynchronous SRAM organized as 8K x 16, with a 25 ns access time that sets the ceiling for read/write cycles when both ports contend for the same address.

Supplied in Tape & Reel (TR) for automated assembly, the device is housed in a 100-LQFP package (supplier device package 100-TQFP, 14x14 mm). Surface-mount mounting — the 0.50 mm pitch demands a controlled solder-paste stencil and a reflow profile matched to the moisture sensitivity level of the package. Rated for commercial temperature range (0°C to 70°C), suitable for indoor equipment, telecom racks, and test instrumentation that does not see extended thermal cycling.

Frequently asked questions

What is the memory organization and access time of CY7C025E-25AXCT?

Organized as 8K x 16 bits with a 25 ns access time. The write cycle time (word/page) is also 25 ns. It is a dual-port asynchronous SRAM — both ports can read or write independently, with arbitration logic handling simultaneous access to the same address.
