The synchronous interface clocks at up to 50 MHz, and the 12 ns access time allows back-to-back read/write cycles with minimal wait states in a shared-memory topology. This part carries an official lifecycle status of Obsolete, meaning Cypress has discontinued production and no last-time-buy window remains open. No direct replacement order code is listed by the manufacturer, so any alternate must be evaluated for pin-compatibility and timing equivalence on a case-by-case basis. Because this is a synchronous dual-port device, both ports can run at the full 50 MHz independently, enabling full-duplex data transfer between two bus masters without dead cycles. ## 100-LQFP package — rework and layout notes","metaTitle":"CY7C09099V-12AC 1Mbit Dual-Port Synchronous SRAM, 12 ns","metaDescription":"Cypress CY7C09099V-12AC 1Mbit dual-port synchronous SRAM, 12 ns access time, 50 MHz clock, 100-LQFP.","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":"Bag","Technology":"SRAM - Dual Port, Synchronous","Access Time":"12 ns","Memory Size":"1Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"100-LQFP","Product Status":"Obsolete","Clock Frequency":"50 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"CY7C09099","Memory Organization":"128K x 8","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"100-TQFP (14x14)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e43ffc67b59981903ef2b49ae3590f6b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C09099V-12AC obsolete?","answer":"Yes, Cypress has marked this part as Obsolete.
