What this synchronous SRAM is and where it fits
The CY7C1440KV33-167AXC is a 36 Mbit synchronous SDR SRAM from Cypress, organized as 1M x 36 and accessed through a parallel interface. It runs at a 167 MHz clock with a 3.4 ns access time, operating from a 3.135 V to 3.6 V supply. The part comes in a 100-LQFP (14x20 mm) surface-mount package and is rated for the commercial temperature range of 0°C to 70°C. This class of synchronous SRAM is used in high-throughput applications such as network packet buffers, DSP coefficient storage, cache memory in embedded processors, and test-and-measurement data acquisition, where deterministic read/write latency and zero dead cycles between bursts are critical.
167 MHz clock and 3.4 ns access — what they mean for bus timing
The 167 MHz clock rate sets the bus speed for pipelined reads and writes. With a 3.4 ns access time, the SRAM can deliver the first word within one clock cycle and sustain back-to-back bursts at full rate.
Commercial temperature grade — environment matters
The 0°C to 70°C operating range limits this part to indoor, temperature-controlled equipment: office networking gear, benchtop instruments, server blades, and telecom central-office racks.
Lifecycle and sourcing posture
The CY7C1440KV33-167AXC carries an active lifecycle status, meaning Cypress (now part of Infineon) continues to manufacture the part. No last-time-buy or end-of-life notice is in effect. For BOM planning, this part is available to order through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.
