The 64-ball FBGA package saves board area compared to TSOP alternatives, though it demands careful PCB layout for signal integrity on the parallel bus. ## 100 ns access time — timing budget for the bus The 100 ns access time sets the window for the host controller to latch data after asserting the address. In a system with a 50 MHz bus clock (20 ns period), this allows five clock cycles for address decode, memory access, and data setup. Designs with slower MCUs or stretched bus cycles have margin; high-speed controllers may need to insert wait states. The 60 ns write cycle time for word and page operations is faster than the read access, so write-heavy firmware updates complete quickly once the bus is idle. ## Industrial temperature range for outdoor and factory environments The 2.7 V minimum supply gives headroom for battery-backed or 3.3 V rail designs with some droop. Storage temperature exceeds the operating range — the package and die handle the thermal cycle, but the board-level solder joints need to match the CTE of the FBGA substrate. The GL-S series is a mature, widely second-sourced NOR Flash family, so supply is stable through both franchised and independent channels. ## Parallel interface and 64-FBGA — board-level considerations The parallel interface uses a 16-bit data bus and separate address lines, which consumes more GPIOs than a serial Flash but delivers faster random read throughput. The 64-ball FBGA (0.8 mm pitch) requires a multi-layer PCB with via-in-pad or dogbone fanout for the inner balls. Decouple with a 100 nF ceramic per supply pin pair, placed as close to the balls as the layout allows.","metaTitle":"S29GL256S10FAIV20 256 Mbit Parallel NOR Flash, 100 ns","metaDescription":"Infineon S29GL256S10FAIV20 GL-S series 256 Mbit Parallel NOR Flash, 100 ns access, 2.7 V, 64-FBGA, -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":"GL-S","has_mpn":"S29GL256","frame_size":"256Mbit","Access Time":"100 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":"2.7","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":"$5.45","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7e8ea6ad0844805b6a061668d2e9e595.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional alternative to the S29GL256S10FAIV20?","answer":"The FM28V102A-TG is a 1 Mbit parallel FRAM with a 90 ns access time and 2.0 V supply, but its 1 Mbit density is 256× smaller than the S29GL256S10FAIV20's 256 Mbit. These are not drop-in replacements — the FM28V parts serve different applications (non-volatile RAM with fast write endurance) versus the GL-S series NOR Flash for code storage.
