This speed grade suits bus arbitration and shared-memory designs where the system clock period is above 55 ns. The commercial temperature range (0°C to 70°C) limits it to controlled indoor environments; no industrial or automotive temperature grade is offered. ## 52-PQFP footprint and board integration Housed in a 52-BQFP (plastic quad flat pack) with a 10x10 mm body — the supplier device package is 52-PQFP. The 0.65 mm pitch gull-wing leads require a surface-mount reflow profile; the package is not moisture-sensitive per typical BQFP ratings, but the reel should be baked per J-STD-033 if the seal is broken and the floor life is exceeded. Infineon lists the CY7C136-55NXCT as Obsolete. No official successor or pin-compatible replacement is recorded from the original manufacturer.","metaTitle":"Infineon CY7C136-55NXCT 16Kbit SRAM, 55 ns, 52-PQFP","metaDescription":"CY7C136-55NXCT 16Kbit dual-port asynchronous SRAM, 55 ns access, 4.5-5.5V, 52-PQFP.
