The parallel interface is straightforward to hook up — address, data, chip enable, output enable, write enable — no clock, no refresh overhead. This is the kind of part that drops into an existing memory socket on a motor drive or a telecom line card without firmware changes. ## Industrial temperature and active lifecycle No official successor has been announced, and the MoBL series continues as an active product line. ## 45 ns access — timing margin for 8-16 MHz buses For a 16 MHz MCU with a 62.5 ns cycle, that leaves about 17 ns of margin after address decode and board trace delay — tight but workable with careful PCB layout. If you are running a faster bus (say 25 MHz or above), you will want a faster SRAM like the CY7C1041 series at 10 ns, but that part is 4 Mbit and organized 256K x 16, so the density and bus width trade-off is real. ## Supply and I/O compatibility The write cycle time matches the read access at 45 ns, so page-mode writes are not supported — each write takes a full cycle.","metaTitle":"Cypress CY62157EV30LL-45BVXI MoBL SRAM, 8 Mbit, 45 ns","metaDescription":"Cypress CY62157EV30LL-45BVXI MoBL 8 Mbit (512K x 16) asynchronous SRAM, 45 ns access, 2.2 V, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"series":"MoBL®","has_mpn":"CY62157","frame_size":"8Mbit","Access Time":"45 ns","memory_type":"Volatile","package_type":"Tray","Memory Format":"SRAM","mounting_type":"Surface Mount","interface_type":"Parallel","product_status":"Active","lifecycle_stage":"eol_hot","supply_voltage_v":"2.2","Memory Organization":"512K x 16","Operating Temperature High":"-40°C to 85°C (TA)","Write Cycle Time - Word, Page":"45ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.87","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ca8c9eac2eaeb0686928c0db93ef1f24.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY62157EV30LL-45BVXI/alternatives.json"},"ai":{"faq":[{"question":"Is CY62157EV30LL-45BVXI RoHS compliant?","answer":"The part number suffix 'XI' indicates a lead-free, RoHS-compliant finish.
