Organised as 64K words of 16 bits each (1 Mbit total), the memory provides a 16-bit parallel interface that matches a 16-bit data bus without byte-lane multiplexing. The date-code and marking consistency should be verified against Infineon's factory etch standards — a mismatch in the laser font or package marking is the first screen for re-marked stock. No official successor or pin-compatible drop-in replacement is recorded from Infineon. A board spin or alternative dual-port SRAM with matching 100-TQFP footprint and 3.3 V supply would require a full requalification. ## Package and supply-rail constraints The supply must be clean; a switching regulator feeding this SRAM should have the ripple held below 50 mV peak-to-peak at the device pins. The part should not be specified for an enclosure that sees sustained temperatures above 70°C or below freezing without active thermal management.","metaTitle":"CY7C028V-20AC Infineon 1Mbit SRAM, 20ns, 100-TQFP","metaDescription":"Infineon CY7C028V-20AC 1Mbit dual-port asynchronous SRAM, 20ns access, 3-3.6V, 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":"Tray","Technology":"SRAM - Dual Port, Asynchronous","Access Time":"20 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C028","Memory Organization":"64K x 16","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x14)","Write Cycle Time - Word, Page":"20ns"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c7336ab15d82b4a3bc513b8e9de4fe35.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the CY7C028V-20AC?","answer":"No official successor or cross-reference alternate appears in the available ledger data for this specific order code.
