What this part is — Cypress NoBL 72Mbit synchronous SRAM
The Cypress CY7C1470BV25-167AXCT is a 72Mbit synchronous SRAM from the NoBL (No Bus Latency) family, organized as 2M x 36. It runs on a 167 MHz clock with a 3.4 ns access time and operates from a 2.375V to 2.625V supply. The part comes in a 100-TQFP (14x20) surface-mount package and is rated for 0°C to 70°C commercial temperature range. It is a volatile memory with a parallel interface, intended for high-bandwidth buffering in networking, telecom, and video processing equipment where back-to-back read/write cycles must avoid dead cycles.
167 MHz clock and 3.4 ns access — what they mean for the bus
The 167 MHz clock drives the 36-bit parallel bus. The 3.4 ns access time is the delay from clock edge to valid data out.
72Mbit density — buffer sizing for line-rate applications
72Mbit (2M x 36) provides depth for a packet buffer or a video frame. The x36 width matches common FPGA memory controller widths.
Lifecycle and sourcing — active, stable supply
The lifecycle status is Active per the manufacturer record. This part is sourced and quoted to order against an RFQ through independent distribution.
