In a system with a 5 V bus running at 25 MHz (40 ns cycle), this leaves 20 ns of margin for address decoding, buffer delays, and setup time to the controller — adequate for most legacy glue-logic designs but tight if cascading multiple memory banks without pipeline registers. Sourcing is limited to surplus inventory and broker channels. The 20-DIP (0.300\", 7.62mm) through-hole package suits socketed prototyping or retrofit into existing PCB layouts with a 0.3\" row spacing.","metaTitle":"CY7C168A-20PXC Cypress SRAM, 16Kbit, 20 ns, Obsolete","metaDescription":"Cypress CY7C168A-20PXC asynchronous SRAM, 16Kbit (4K x 4), 20 ns access time, 4.5V-5.5V, 0°C-70°C, 20-DIP.","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":"Tube","Technology":"SRAM - Asynchronous","Access Time":"20 ns","Memory Size":"16Kbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Through Hole","Package / Case":"20-DIP (0.300\\\", 7.62mm)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"CY7C168","Memory Organization":"4K x 4","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"20-DIP","Write Cycle Time - Word, Page":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.2400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/25561d2d5f234dcdba4c3febf1b4ab63.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/CY7C168A-20PXC/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/CY7C168A-20PXC","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/CY7C168A-20PXC when reusing this data.
