Memory fit for a 64K x 16 data bus
The 71V016SA20BFG8 is a 1 Mbit asynchronous SRAM organized as 64K words by 16 bits, accessed in parallel with a 20 ns read/write cycle. The 20 ns access time means the memory can deliver or capture data on a 50 MHz bus without wait states, assuming the controller's output hold time and board trace delay are within budget.
Package and board integration
Supplied in a 48-ball LFBGA (CABGA) package measuring 7 mm x 7 mm, the 71V016SA20BFG8 mounts on the board surface. The fine-pitch BGA requires a controlled solder-paste stencil and reflow profile typical for 0.5 mm to 0.65 mm ball pitch — a 4-layer PCB with microvias under the balls is common for fan-out. The commercial temperature range (0°C to 70°C) limits the part to indoor, non-condensing environments; an industrial-temperature variant would be needed for outdoor or engine-bay deployment.
