It combines the density of DRAM with an SRAM-like interface, eliminating the need for refresh management from the host. The part runs on a 1.7 V to 2 V supply and communicates over a HyperBus at up to 200 MHz, delivering a 35 ns initial access time and sustained throughput suitable for code shadowing, display frame buffers, or packet buffering in embedded systems. ## 35 ns access time — what it means for the bus The 35 ns access time is the random-read latency from the first HyperBus command to the first data word. In a system with a 200 MHz HyperBus clock (5 ns period), this translates to about 7 clock cycles before data starts streaming. This is on par with other HYPERRAM devices and well within the timing budget for most Cortex-M and RISC-V SoCs that integrate a HyperBus controller. The 200 MHz clock also gives a theoretical peak data rate of 400 MB/s in DDR mode (double data rate), though real throughput depends on controller efficiency and bus utilization. ## Industrial temperature and supply range Rated for -40°C to 85°C ambient, this part is suited for outdoor telecom, factory automation, and industrial control enclosures where temperature swings are common. The 1.7 V to 2 V supply range aligns with low-power SoC rails; note the upper limit is 2 V, not the typical 3.3 V, so a dedicated regulator or PMIC rail is required. The 49-FBGA (8x8 mm) package uses a 0.8 mm ball pitch, which is routable on a standard 4-layer PCB with blind vias if needed. ## Active lifecycle — no LTB risk S80KS2564GACHI040 carries an Active lifecycle status. It is ROHS3 compliant. For new designs, this part is a safe selection today, though as with any single-sourced memory, maintaining a qualified second source is good practice for production continuity.","metaTitle":"Infineon S80KS2564GACHI040 HYPERRAM™ 256 Mbit PSRAM, 200 MHz","metaDescription":"S80KS2564GACHI040 from Infineon is a 256 Mbit PSRAM with HyperBus interface, 35 ns access time, 200 MHz clock, industrial temp -40°C to 85°C, 49-FBGA.","metaKeywords":null},"attributes":{"series":"HYPERRAM™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"HYPERRAM™","Package":"Tray","Technology":"PSRAM (Pseudo SRAM)","Access Time":"35 ns","Memory Size":"256Mbit","Memory Type":"Volatile","Memory Format":"PSRAM","Mounting Type":"Surface Mount","Package / Case":"49-VBGA","Clock Frequency":"200 MHz","lifecycle_stage":"eol_hot","Memory Interface":"HyperBus","Voltage - Supply":"1.7V ~ 2V","Memory Organization":"16M x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"49-FBGA (8x8)","Write Cycle Time - Word, Page":"35ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$15.55","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$15.55000","currency":"USD"},{"qty":10,"price":"$14.39600","currency":"USD"},{"qty":25,"price":"$14.20080","currency":"USD"},{"qty":40,"price":"$14.02250","currency":"USD"},{"qty":80,"price":"$12.93250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2e1471bdd68d6029fa4e82138cabde44.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time of S80KS2564GACHI040?","answer":"The S80KS2564GACHI040 has a 35 ns initial access time for random reads on the HyperBus interface."},{"question":"Is S80KS2564GACHI040 active or obsolete?","answer":"It is Active per the manufacturer's lifecycle status — no discontinuation or last-time-buy is in effect."},{"question":"What is the difference between HyperRAM and HyperFlash?","answer":"HyperRAM (like this S80KS2564GACHI040) is volatile PSRAM used for temporary data storage, while HyperFlash is non-volatile NOR Flash for code storage.
