The 36-bit word width maps directly to a 32-bit data bus plus 4 parity or ECC bits in a single chip — no need for a second device to cover the parity lane. The 100-TQFP (14x20 mm) package with 0.5 mm pitch requires a four-layer PCB for clean fan-out of the 36 data lines plus address and control signals. The part is no longer supported for new designs and the last-time-buy window has closed. Available inventory is held in independent distribution and surplus channels. For a BOM that already carries this order code, the procurement path is through the spot market — not the factory. ## Board-fit and supply integration Decoupling with 0.1 µF and 10 µF ceramics per supply pin is standard for this clock rate. The 250 MHz clock input is LVTTL-compatible; the output drivers are also LVTTL with controlled impedance to reduce reflection on the data bus at this frequency.","metaTitle":"Infineon CY7C1347G-250AXCT 4.5Mbit SRAM, 250 MHz, 100-TQFP","metaDescription":"Obsolete 4.5Mbit synchronous SRAM, 128K x 36, 250 MHz clock, 2.6 ns access, 3.15-3.6V, 100-TQFP.
