The 7.5 ns access time gives the memory controller a full cycle to latch data without wait states, critical for back-to-back read/write pipelines in networking buffers or cache-line fills. NoBL architecture eliminates the dead cycle on bus-turnaround that conventional sync SRAMs require, so the data bus stays saturated at the 100 MHz rate. ## Wide word width — 36-bit organization for parity or ECC The 256K x 36 organization supports a 32-bit data word plus 4 parity/ECC bits in a single chip, saving board area versus two x18 parts. This is a natural fit for telecom line cards, packet buffers, and RAID controllers where data integrity over a wide bus matters more than raw density. The parallel interface keeps the pin count manageable in the 100-TQFP package. ## Commercial temperature grade — indoor equipment only It is not specified for industrial or automotive thermal ranges, so a motor-drive or under-hood application would need a wider-temperature sibling. ## Supply rail and decoupling The 100-TQFP (14x20 mm) footprint requires a solid ground plane and a 0.1 µF ceramic per supply pin within 5 mm of the package to keep switching noise under the 7.5 ns access window.","metaTitle":"CY7C1355C-100AXCT NoBL SRAM, 9Mbit 256Kx36, 100MHz, 7.5ns","metaDescription":"Infineon CY7C1355C-100AXCT NoBL synchronous SRAM, 9 Mbit (256K x 36), 100 MHz clock, 7.5 ns access, 3.135V–3.6V, 0°C–70°C, 100-TQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"NoBL™","Package":"Tape & Reel (TR)","Technology":"SRAM - Synchronous, SDR","Access Time":"7.5 ns","Memory Size":"9Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"100 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1355","Memory Organization":"256K x 36","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ed84243fe66837106fd618dc4170b8ee.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C1355C-100AXCT?","answer":"For new designs, consider a current-production synchronous SRAM from the same NoBL family with matching 100 MHz clock and 256K x 36 organization; verify pin-compatibility and timing in the target datasheet."},{"question":"Can CY7C1355C-100AXCT replace CY7C1355C-100AXC?","answer":"The CY7C1355C-100AXCT (Tape & Reel) and CY7C1355C-100AXC (tray) are electrically identical — same 9 Mbit NoBL SRAM, 100 MHz, 7.5 ns access, 100-TQFP.
