In a dual-port configuration, both ports operate asynchronously, so the access time directly affects how quickly a master can complete a read or write cycle. For a system running at 25 MHz or slower, 20 ns leaves comfortable margin; at higher bus speeds, the address-to-data valid window tightens and may require wait-state insertion. The parallel interface uses separate address and data buses, so PCB layout must manage trace lengths to keep skew within the 20 ns window. ## 512Kbit in a 100-pin TQFP — density and footprint The 32K x 16 organization provides 512Kbit of volatile storage in a 100-TQFP package with a 14x14 mm body. The 100-pin count accommodates the dual-port address and data buses plus control signals. Surface-mount assembly is standard; the TQFP footprint is fine-pitch (0.5 mm typical), so solder-paste stencil aperture and reflow profile should follow the manufacturer's guidelines for MSL-rated devices. The industrial temperature grade covers most factory-floor and outdoor telecom enclosures.","metaTitle":"Infineon CY7C027-20AXIT SRAM Dual Port, 512Kbit, 20 ns","metaDescription":"Infineon CY7C027-20AXIT 512Kbit (32K x 16) dual-port asynchronous SRAM, 20 ns access time, -40°C to 85°C, 100-TQFP.
