That matters when you're buffering real-time data or swapping context in a soft-core processor. ## Package and footprint — 36-SOJ Housed in a 36-SOJ (0.400\" body width, 10.16 mm) surface-mount package, this part uses the JEDEC SOJ footprint common on 1990s–2000s embedded boards. The supplier device package is 36-SOJ, so any replacement candidate must match that mechanical outline and pinout. Not suitable for outdoor, under-hood, or unconditioned environments. If your application sees -20°C or +85°C ambient, you need the industrial-temperature variant in this family. For new designs, look at the current-generation asynchronous SRAMs in the same 36-SOJ footprint — many from Cypress (now Infineon) and ISSI share the pinout. No last-time-buy window remains; stock is what's in the channel.","metaTitle":"Cypress CY7C1049BV33-20VC 4Mbit Async SRAM, 20 ns, 36-SOJ","metaDescription":"Cypress CY7C1049BV33-20VC 4Mbit (512K x 8) asynchronous SRAM, 20 ns access time, 3V–3.6V supply, 36-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":"20 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":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.7700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aaf4cbc2ae8d35ea1c71b6865bdf43d2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1049BV33-20VC/alternatives.json"},"ai":{"faq":[{"question":"What is a direct replacement for CY7C1049BV33-20VC?","answer":"No single direct replacement is recorded in the official Cypress documentation.
