What this NVSRAM brings to the bus
The Infineon CY14V116N-BZ30XI is a 16Mbit non-volatile SRAM organized as 1M x 16 bits with a parallel interface and a 30 ns access time. It stores data without a battery—the NVSRAM cell combines the read/write speed of a standard SRAM with on-chip non-volatile elements that hold the contents at power-down.
30 ns access — timing headroom for the bus
The 30 ns access time is the cycle the part needs to present valid data after the address is stable.
The part is supplied in a 165-ball LBGA (FBGA) with a 15 x 17 mm body. It is surface-mount only, so the PCB footprint needs a fine-pitch BGA land pattern with via-in-pad or microvia escape routing for the inner balls.
