This part was designed for high-speed cache, buffer, or scratchpad memory in systems that need fast random access without the complexity of synchronous clocking. For a legacy DSP or FPGA design that already has a 5 V supply rail and a parallel memory controller, this part fits directly into the timing budget without needing a PLL or DLL to deskew the data. The 10 ns write cycle time (word and page) matches the read access, so back-to-back read-write sequences run at full speed with no dead cycles. Infineon (formerly Cypress) has discontinued production; there is no last-time-buy window remaining. Any units on the market are new-old-stock or surplus inventory. ## Package and footprint — what the SOJ means on the board The 28-SOJ package (JEDEC MO-119 variant, 0.400\" body width, 10.16 mm) is a gull-wing lead form with a 1.27 mm pitch. It is a surface-mount part but the leads are on the outer edges — no thermal pad underneath. The Tube shipping medium (25 pieces per tube) is typical for this package; reels are available under alternate order codes.","metaTitle":"Infineon CY7C106D-10VXI SRAM, 1 Mbit, 10 ns, 4.5-5.5 V","metaDescription":"Infineon CY7C106D-10VXI asynchronous SRAM, 1 Mbit (256K x 4), 10 ns access time, 4.5 V to 5.5 V supply, -40°C to 85°C, 28-SOJ package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Technology":"SRAM - Asynchronous","Access Time":"10 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"28-BSOJ (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C106","Memory Organization":"256K x 4","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"28-SOJ","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/472783e78dcaa788576e9dc503f2f383.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for CY7C106D-10VXI?","answer":"Infineon does not list a direct replacement for this exact order code. The closest pin-compatible alternative is the CY7C106D-10VXIT (the tape-and-reel variant of the same die), but that is also obsolete.
