On a 50 MHz bus that gives roughly one clock cycle of margin for address decoding and trace delay before the data is latched. If your system runs a 66 MHz or faster bus, you need to check whether the address-to-data timing still closes — this part is sized for the 50 MHz and below sweet spot. Infineon has announced the end of production; there is a final purchasing window, after which the part will no longer be manufactured. ## No lab, no bench — field-swap considerations The 44-TSOP II package is a surface-mount gull-wing lead form, not socket-friendly. Swapping this on site means hot air or a reflow station — not a field kit job unless you carry a preheated plate and the right nozzle. Orientation is obvious from the pin-1 chamfer, but the fine pitch (0.8 mm typical for TSOP II) demands good alignment. If you are planning a field repair, stock a few pre-programmed spares on a small carrier board or order the part programmed and tested before the Last Buy window closes.","metaTitle":"Infineon CY7C1041GE-10ZSXI Async SRAM, 4Mbit, 10ns","metaDescription":"Infineon CY7C1041GE-10ZSXI asynchronous SRAM, 4Mbit (256K x 16), 10 ns access, 4.5V–5.5V, -40°C to 85°C, 44-TSOP II.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tray","Technology":"SRAM - Asynchronous","Access Time":"10 ns","Memory Size":"4Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (0.400\\\", 10.16mm Width)","Product Status":"Last Time Buy","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C1041","Memory Organization":"256K x 16","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.2900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4b583d433046ca582816ac98334bd436.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C1041GE-10ZSXI/alternatives.json"},"ai":{"faq":[{"question":"Is CY7C1041GE-10ZSXI compatible with 3.3V?","answer":"It is not rated for 3.3V operation.
