133 MHz clock — bus timing for the system architect
The CY7C1297H-133AXC is a 1 Mbit synchronous SRAM organized as 64K words by 18 bits. The 133 MHz clock frequency sets the read/write cycle timing — at this speed, the memory interface can sustain back-to-back transactions without wait states, provided the controller's output hold and setup margins are met. The 18-bit data width suits applications needing a parity or ECC bit alongside a 16-bit data word, or a narrower 9-bit bus with byte selects.
Supply and temperature — commercial-grade only
Package and footprint — 100-TQFP
Housed in a 100-TQFP (14x20 mm) package, surface-mount. The supplier device package is 100-TQFP (14x20). The shipping medium is Tray. For rework, the standard JEDEC MSL profile applies — no special bake required unless the moisture-barrier bag has been breached.
