The Infineon CY7C1440KV33-250AXC is a 36Mbit synchronous SRAM organized as 1M x 36, clocked at 250 MHz with a 2.6 ns access time. It uses a parallel memory interface and operates from a 3.135V to 3.6V supply.
The 250 MHz clock rate and 2.6 ns access time define the part's speed bin. In a 250 MHz synchronous bus, the 2.6 ns access means the SRAM can present valid data within one clock cycle after the address is latched, leaving margin for PCB trace delay and setup time at the controller. This is the spec that determines whether the part can keep the pipeline full without wait states in a back-to-back read or write sequence.
This means Infineon has announced end-of-life for this order code and is accepting final purchase orders within a defined window. After the last buy date passes, the part will no longer be manufactured and will only be available through the surplus and broker channel.
Package and footprint — 100-TQFP (14x20)
The 14x20 mm body footprint is standard for this density of synchronous SRAM; layout reuse across density variants in the same package is straightforward.
