That maps cleanly to a 16-bit data bus — common on 16-bit microcontrollers, DSPs, and older x86-class embedded processors. If your processor uses an 8-bit bus, you either waste half the memory or need byte-lane control logic. The 10 ns write cycle time (word and page) matches the read access, so back-to-back writes at bus speed are possible without dead cycles — important for FIFO or cache-line fill operations. ## 44-TSOP II — footprint and handling The 44-TSOP II package (0.400\" body width, 10.16 mm) is a standard thin small-outline package with gull-wing leads. It is surface-mount, reflow-compatible, and widely used in memory modules. The Tape & Reel (TR) shipping format means it loads directly into a pick-and-place feeder — no tube handling.","metaTitle":"Cypress CY7C10211BN-10ZXCT 1Mbit Async SRAM, 10 ns","metaDescription":"Cypress CY7C10211BN-10ZXCT 1Mbit asynchronous SRAM, 10 ns access time, 64K x 16, 4.5V-5.5V, 44-TSOP II.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Technology":"SRAM - Asynchronous","Access Time":"10 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"44-TSOP (0.400\\\", 10.16mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C1021","Memory Organization":"64K x 16","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"44-TSOP II","Write Cycle Time - Word, Page":"10ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/87056a907f3868cf5838858aebd2682e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C10211BN-10ZXCT obsolete?","answer":"Yes, the CY7C10211BN-10ZXCT is listed as Obsolete. Cypress has ended production, and no direct replacement part number has been published. For new designs, you will need to evaluate a pin-compatible asynchronous SRAM from another vendor."},{"question":"What is the replacement for CY7C10211BN-10ZXCT?","answer":"Several memory vendors (ISSI, Alliance Memory, GSI Technology) offer functionally equivalent parts in the same package and speed grade — verify pin compatibility against the CY7C1021 base part number's datasheet before committing the BOM."},{"question":"Is CY7C10211BN-10ZXCT compatible with 5V systems?","answer":"Yes, the supply range is 4.5V to 5.5V, which covers a nominal 5V rail with typical ±10% tolerance. All I/O signals are 5V-tolerant, so it interfaces directly with 5V logic families (TTL, 5V CMOS) without level shifters. Do not use it on a 3.3V-only bus — the minimum supply is 4.5V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C10211BN-10ZXCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C10211BN-10ZXCT when reusing this data.
