The 6.5 ns access time means the output data is valid one clock cycle after the address is latched — no wait states needed when the bus controller runs at 133 MHz. The x18 data width naturally pairs with a parity or ECC nibble on a 16-bit data bus, or serves as a standalone 18-bit wide memory for packet buffers and FIFO emulation. ## Last Buy — LTB window is open, plan your final orders Infineon has marked the CY7C1363C-133AXC as Last Buy. That means the manufacturer is taking final purchase orders for a limited window; once that window closes, the part enters end-of-life and only surplus/broker inventory remains. If your BOM still calls out this exact order code, now is the time to commit the lifetime buy quantity or qualify a replacement. ## Pin-compatible density step — CY7C1325G-133AXC at 4.5 Mbit If the 9 Mbit density is more than your application needs, the CY7C1325G-133AXC halves the memory to 4.5 Mbit (256K x 18) while keeping the same 133 MHz clock, 6.5 ns access, 3.3 V supply, and 100-TQFP footprint. The pinout matches across the x18 density family, so a board layout designed for the CY7C1363C can fit the CY7C1325G without a respin — useful for cost-down or allocation workarounds. ## Commercial temp only — keep it indoors No industrial or automotive qualification. If your system sees -40°C or +85°C ambient, this SRAM is not the right fit — look at the industrial-temperature variants in the same family (e.g., CY7C1363C-133AXI).","metaTitle":"CY7C1363C-133AXC 9Mbit Sync SRAM, 133 MHz, 6.5 ns","metaDescription":"Infineon CY7C1363C-133AXC 9Mbit synchronous SRAM, 133 MHz clock, 6.5 ns access. 100-TQFP, 0-70°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Synchronous, SDR","Access Time":"6.5 ns","Memory Size":"9Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Last Time Buy","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.6V","Base Product Number":"CY7C1363","Memory Organization":"512K x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/25ee5b83ca7d8f09e984f37e39e01b05.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1363C-133AXC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1363C-133AXC obsolete?","answer":"Infineon lists the CY7C1363C-133AXC as Last Buy.

If you need a higher-performance drop-in, the CY7C1356C-250AXC runs at 250 MHz with 2.8 ns access in the same 100-TQFP and 512K x 18 organization, but it uses NoBL (No Bus Latency) architecture — verify controller compatibility before swapping.
