144Mbit DDR II+ SRAM at 400 MHz — what the clock rate means for the buffer
The CY7C1650KV18-400BZC is a 144Mbit synchronous SRAM organized as 4M x 36, clocked at 400 MHz with a DDR II+ interface — each clock edge transfers data, so the effective data rate is 800 MT/s per I/O pin.
Package and board-fit — 165-FBGA reflow considerations
Housed in a 165-ball FBGA (15x17 mm), the fine-pitch BGA demands a controlled reflow profile and careful moisture management — check the MSL rating before the oven or the package popcorns. Supplied in tray format, which is standard for BGA devices in prototype and low-to-medium volume assembly; the tray protects the solder balls from damage during handling.
