The parallel interface is straightforward to hook up — address, data, chip enable, output enable, write enable — no clock, no refresh overhead. Rated for a supply range of 3V to 3.6V, this SRAM operates directly from a 3.3V rail without external level shifters. That covers the vast majority of 3.3V logic systems — FPGAs, ASICs, and microcontrollers with parallel memory interfaces. The write cycle time matches the read access time at 15 ns, so the bus timing is symmetric for read and write operations. Not rated for industrial enclosures, outdoor cabinets, or automotive under-hood use; those applications would require an industrial or automotive temperature grade part. ## 36-SOJ footprint — board layout check Packaged in a 36-lead SOJ (Small Outline J-lead) with a 0.400-inch (10.16 mm) body width. MSL level is typical for this package type, but check the moisture sensitivity label on the tube. Cypress (now part of Infineon) no longer manufactures the CY7C1049BV33-15VC in volume.","metaTitle":"CY7C1049BV33-15VC Cypress SRAM, 4Mbit 15ns 36-SOJ","metaDescription":"CY7C1049BV33-15VC Cypress 4Mbit (512K x 8) asynchronous SRAM, 15ns access, 3V-3.6V, 0°C-70°C, 36-SOJ.","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":"15 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"36-BSOJ (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C1049","Memory Organization":"512K x 8","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"36-SOJ","Write Cycle Time - Word, Page":"15ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.1900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aaf4cbc2ae8d35ea1c71b6865bdf43d2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1049BV33-15VC/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1049BV33-15VC compatible with 3.3V logic?","answer":"Yes.
