For a processor running at 50 MHz (20 ns cycle), that leaves a 10 ns window for address decode, board trace delay, and setup time at the host — enough margin for a clean single-cycle read without stretching the bus.
1M x 16 organization — 16-bit data path without byte-lane muxing
The 1M x 16 organization presents a full 16-bit word on each access, so a 16-bit host reads or writes one address per cycle without byte-lane steering. For an 8-bit host the part can be wired as two 8-bit banks using the upper and lower byte enables, but the natural fit is a 16-bit data bus where it saves a multiplexer and simplifies the layout.
Package and footprint — 48-TSOP I
The 48-TSOP I (0.724" body width, 18.40 mm) is a standard thin small-outline package with a 0.5 mm lead pitch. It is a surface-mount footprint shared across the CY7C1061 family, so a layout done for the -10ZXI speed grade or the -10ZXI industrial temperature variant routes identically. The Tape & Reel (TR) suffix means this ships on a 13-inch reel for automated pick-and-place.
