Timing and temperature grade
The CY7C1021BV33-15ZC: The 15 ns access time and 15 ns write cycle time (word/page) set the bus timing ceiling — the SRAM can complete a read or write in a single 66 MHz cycle, but the controller's address-to-data setup must hold within that window.
The bag packaging indicates tube or tray delivery; no reel or tape-and-reel for automated pick-and-place, so factor in manual or tube-fed handling for production.
