333 MHz QDR II SRAM — 72 Mbit in a 165-ball FBGA
The CY7C1514KV18-333BZI is a 72 Mbit synchronous SRAM organised as 2M x 36, using the QDR II architecture that delivers independent read and write data ports on every clock edge (cite:,). The 333 MHz clock rate yields a peak bandwidth of 2.4 Gbytes/s per device, which is the headline number for a network buffer or high-speed lookup table (cite:).
Package and board integration — 165-FBGA (13x15 mm)
The 0.80 mm ball pitch is manageable on a 4-layer board; a 6-layer design gives cleaner signal return paths for the 333 MHz data strobes.
The base product number CY7C1514 identifies the 72 Mbit QDR II family; speed and temperature variants share the same footprint, which simplifies BOM consolidation if a faster or wider part is needed later (cite:).
