The 32-bit wide data bus matches well with 32-bit processor and DSP memory interfaces, reducing the chip count versus narrower memories. ## 166 MHz clock and 3.5 ns access time — timing budget for the bus At 166 MHz the clock period is about 6 ns. With a 3.5 ns access time, the memory leaves roughly 2.5 ns of setup-and-hold margin for the controller — tight but workable with proper PCB trace-length matching and controlled impedance on the data and address lines. This part is sized for designs that cannot tolerate the dead cycles of a late-write or flow-through asynchronous SRAM; every clock edge delivers a word. ## Package and footprint — 100-TQFP (14x20) The exposed pad (if present on this variant) should be stitched to ground plane with thermal vias for heat spreading. Any BOM using this part should plan for a last-time-buy or a qualification of a newer synchronous SRAM family.","metaTitle":"CY7C1329H-166AXCT SRAM, 2Mbit, 166 MHz, 3.5 ns, 100-TQFP","metaDescription":"Cypress CY7C1329H-166AXCT synchronous SDR SRAM, 2Mbit (64K x 32), 166 MHz clock, 3.5 ns access time, 3.15V-3.6V, 100-TQFP.","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 - Synchronous, SDR","Access Time":"3.5 ns","Memory Size":"2Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"166 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.15V ~ 3.6V","Base Product Number":"CY7C1329","Memory Organization":"64K x 32","Operating Temperature":"0°C~70°C(TA)","Supplier Device Package":"100-TQFP (14x20)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/32932654955469dd27344dc01a2c1362.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy CY7C1329H-166AXCT?","answer":"Submit a request for current availability and pricing — we confirm both at quote time."},{"question":"What is the replacement for CY7C1329H-166AXCT?","answer":"No official pin-compatible replacement is recorded in the available documentation.
