What this QDR II SRAM is and where it fits
The Infineon CY7C1412BV18-200BZI is a 36 Mbit QDR II synchronous SRAM organized as 2M x 18 bits, clocked at 200 MHz. It is a volatile memory with a parallel interface, designed for high-bandwidth, low-latency applications such as network packet buffers, telecom line cards, and high-end test equipment. The 1.7 V to 1.9 V supply and industrial temperature range (-40°C to 85°C) suit it for outdoor telecom cabinets and factory-floor controllers where ambient temperature swings are common.
Obsolete — sourcing and lifecycle reality
Package and layout constraints
The 165-ball FBGA (15x17 mm) package requires a multi-layer PCB with controlled impedance traces for the 200 MHz clock and data lines.
