36 Mbit QDR II — 200 MHz synchronous SRAM
The CY7C1414AV18-200BZC is a 36 Mbit synchronous SRAM using the QDR II (Quad Data Rate) architecture — it transfers data on both rising and falling edges of the clock on separate read and write ports, effectively quadrupling the data rate relative to a single-port SDR device at the same 200 MHz clock. Organized as 1M x 36, the 36-bit-wide word matches the bus width of many network processors and FPGA soft-core memory controllers — one chip provides a full 36-bit transaction per clock edge without byte-lane gating. Operating from a 1.7 V to 1.9 V core supply, the I/O voltage is typically 1.5 V or 1.8 V HSTL — the parallel interface requires matched on-die termination and reference voltage (Vref) on the PCB to hold signal integrity at the 200 MHz double-data-rate edge rate.
165-FBGA package and board integration
Housed in a 165-ball FBGA measuring 15 x 17 mm, the package uses a 1.0 mm ball pitch — a standard 4-layer PCB with microvias can fan out the inner rows, though the 36-bit data bus plus address and control signals typically demand at least six signal layers in a high-speed memory channel.
