The 9th bit per word is typically used for parity or a control flag, giving the 128K x 9 organization an edge over a standard x8 part in data-integrity applications. Dual-port architecture means two independent buses can read or write to any memory location simultaneously — no arbitration delay for the second port as long as both sides avoid the same address in the same cycle. This is the key differentiator from a single-port SRAM where the bus must be shared or multiplexed. ## 5 V supply, 100-LQFP — legacy system fit This is the standard indoor equipment temperature band; not qualified for industrial or automotive extended-range environments. ## Obsolete — sourcing through independent channels Available through independent surplus and broker channels. Quantities are lot-specific; pricing and availability are confirmed at the time of an RFQ. No pin-compatible direct replacement is documented by Infineon — a board-level change may be required for a functional substitute.","metaTitle":"Infineon CY7C09199-9AC 1.152Mbit Dual-Port SRAM, 9ns","metaDescription":"CY7C09199-9AC synchronous dual-port SRAM, 1.152Mbit (128K x 9), 9ns access, 67 MHz, 5V, 100-LQFP.
