The 100 ns access time sets the read-cycle window the host controller must budget; at that speed, a 16-bit microcontroller can fetch a 16-bit instruction every 100 ns without wait states, provided the bus timing closes. ## Write-cycle timing and page-mode detail Word and page writes complete in 60 ns per the write-cycle time spec. That figure is the pulse width for a single write operation, not the erase or program time — the GL-S family uses a command-based write state machine, so the host issues a write command, then polls the status register or waits for the ready/busy signal. For bulk programming, page-mode writes let you load up to 256 words per write buffer, which improves throughput over single-word writes. ## Package and footprint — 56-TSOP surface mount The part ships in a 56-TFSOP package (0.724\" body width, 18.40 mm) with a surface-mount footprint. It's a tray-packaged device, so expect tube or tray handling rather than tape-and-reel — verify the pick-and-place feeder setup if you're running high-volume assembly.","metaTitle":"S29GL256S10TFIV20 Infineon 256Mbit Parallel NOR Flash","metaDescription":"Infineon S29GL256S10TFIV20 256Mbit parallel NOR Flash, 100 ns access time, 1.65V-3.6V, -40°C to 85°C, 56-TSOP, active lifecycle.","metaKeywords":null},"attributes":{"series":"GL-S","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"GL-S","Package":"Tray","Technology":"FLASH - NOR","Access Time":"100 ns","Memory Size":"256Mbit","Memory Type":"Non-Volatile","Memory Format":"FLASH","Mounting Type":"Surface Mount","Package / Case":"56-TFSOP (0.724\\\", 18.40mm Width)","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"1.65V ~ 3.6V","Memory Organization":"16M x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"56-TSOP","Write Cycle Time - Word, Page":"60ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.78","priceTiers":[{"qty":1,"price":"$7.78000","currency":"USD"},{"qty":10,"price":"$7.15700","currency":"USD"},{"qty":25,"price":"$7.00800","currency":"USD"},{"qty":40,"price":"$6.98375","currency":"USD"},{"qty":91,"price":"$6.26648","currency":"USD"},{"qty":273,"price":"$6.07711","currency":"USD"},{"qty":455,"price":"$5.77888","currency":"USD"},{"qty":1001,"price":"$5.57738","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7e8ea6ad0844805b6a061668d2e9e595.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/S29GL256S10TFIV20/alternatives.json"},"ai":{"faq":[{"question":"What is the memory size and organization of S29GL256S10TFIV20?","answer":"The memory size is 256 Mbit, organized as 16M x 16 bits (16 million 16-bit words). The 16-bit-wide data bus is a natural fit for 16-bit microcontrollers and DSPs, reducing the number of read cycles needed for 16-bit instructions or data words."},{"question":"Is S29GL256S10TFIV20 parallel or serial interface?","answer":"It uses a parallel memory interface. The parallel bus provides higher throughput than serial NOR Flash for random-access reads, which is valuable for execute-in-place (XIP) code storage where the CPU fetches instructions directly from the Flash."},{"question":"Is S29GL256S10TFIV20 RoHS compliant and lead-free?","answer":"Yes, it is ROHS3 compliant, meaning it meets the EU RoHS directive including the four phthalates (DEHP, BBP, DBP, DIBP) in addition to the original six restricted substances. It is lead-free and suitable for lead-free soldering processes."},{"question":"Can I replace S29GL256S10TFIV20 with S29GL256S10TFIV30?","answer":"The S29GL256S10TFIV30 is a different suffix variant within the same GL-S series. The evidence does not provide a direct cross-reference or pin-compatible claim between these two suffixes.
