This is a volatile memory — data is lost when power is removed. The part delivers data within 12 ns of the address being valid. Infineon (formerly Cypress Semiconductor) has marked the CY7C1020B-12VXC as obsolete. The package is a 44-lead SOJ with a 0.400\" body width and 10.16 mm body width.","metaTitle":"Infineon CY7C1020B-12VXC 512Kbit SRAM, 12 ns, 44-SOJ","metaDescription":"Infineon CY7C1020B-12VXC asynchronous SRAM, 512Kbit (32K x 16), 12 ns access time, 4.5V-5.5V supply, 44-SOJ, 0°C-70°C.","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":"12 ns","Memory Size":"512Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-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":"CY7C1020","Memory Organization":"32K x 16","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"44-SOJ","Write Cycle Time - Word, Page":"12ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9974","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/46835e03ed03fca647fb9f9aa23e92c6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1020B-12VXC/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for CY7C1020B-12VXC?","answer":"There is no official replacement part number listed by Infineon for the CY7C1020B-12VXC. For new designs, look for a current-production asynchronous SRAM in a 44-SOJ or 44-TSOP-II footprint with a 5V supply, 512Kbit x16 organization, and 12 ns or faster access time. Several vendors (ISSI, Alliance Memory, Renesas) offer pin-compatible parts in this density and speed class. For existing BOMs that must use this exact code, the part is sourced through surplus channels."},{"question":"What voltage does CY7C1020B-12VXC require?","answer":"It is a 5V nominal part and will not operate from a 3.3V rail.
