This part is housed in a 64-ball FBGA package and is intended for code-shadowing, firmware storage, and data-logging in embedded systems where reliable random-access read performance and long-term data retention are required. The 110 ns access time is the random-read cycle time from address latch to valid data on the bus. For a host controller running at, say, 50 MHz (20 ns period), the flash read cycle takes about 5.5 clock cycles. That is well within the margin of most external memory controllers, but if your design uses a faster clock or back-to-back reads, you need to check the controller's wait-state configuration. The 60 ns word/page write cycle time is the spec for programming — it governs firmware update throughput, not read performance. ## 1.65 V supply — direct connect to 1.8 V logic The 1.65 V minimum supply voltage lets this flash run directly from a 1.8 V rail without an external level shifter on the address/data bus. That saves two or three octals on the BOM and simplifies the PCB routing. ## Industrial temperature range — where it fits It is not specified for under-hood or engine-bay environments where junction temperatures exceed 105°C. If your application sees sustained temperatures above 85°C ambient, look at the GL-T or HyperFlash families that carry extended temp ratings. ## Package and footprint — 64-ball FBGA The tray shipping medium means the parts arrive in antistatic trays, not tape-and-reel — factor that into your pick-and-place feeder setup if you are using reel-fed assembly. MSL is typically 3 for this package family; bake before reflow if the moisture-barrier bag has been open beyond the floor-life window.","metaTitle":"S29GL256S11FHIV20 256 Mbit Parallel NOR Flash, 110 ns","metaDescription":"Cypress S29GL256S11FHIV20 GL-S 256 Mbit parallel NOR flash, 110 ns access, 1.65 V supply, -40°C to 85°C, 64-ball FBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"series":"GL-S","has_mpn":"S29GL256","frame_size":"256Mbit","Access Time":"110 ns","memory_type":"Non-Volatile","package_type":"Tray","Memory Format":"FLASH","mounting_type":"Surface Mount","interface_type":"Parallel","product_status":"Active","lifecycle_stage":"eol_hot","supply_voltage_v":"1.65","Memory Organization":"16M x 16","Operating Temperature High":"-40°C to 85°C (TA)","Write Cycle Time - Word, Page":"60ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.72","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7e8ea6ad0844805b6a061668d2e9e595.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent part for S29GL256S11FHIV20?","answer":"A higher-density sibling in the same GL-S family is the S29GL512T11TFIV20 (512 Mbit, 64M x 8 organization, same 110 ns access and 1.65 V supply). The S29GL128S10TFIV13 is a lower-density option (128 Mbit, 8M x 16, 100 ns access).
