That 133 MHz synchronous interface means both ports can arbitrate and transfer data on every clock edge without dead cycles between reads and writes — critical for shared-memory designs where two processors or controllers need low-latency access to the same buffer. The x18 word width supports an 8-bit data byte plus a parity bit per port, or a 16-bit datapath with two parity/control bits, which is a common requirement in telecom line cards and baseband processing. ## Obsolete — no direct replacement on record This is a last-time-buy reality: if your board spins still require this footprint and timing, securing a lifetime buy quantity or qualifying a pin-compatible second source should be on the roadmap. ## Package and temperature — fit for controlled environments Housed in a 120-LQFP (also specified as 120-TQFP 14x14 mm), this is a surface-mount part with a 0.5 mm pitch — standard for fine-pitch assembly lines. ## Where the 133 MHz clock matters in arbitration At 133 MHz, the synchronous dual-port architecture gives each port a full clock cycle to arbitrate access to the memory array. This avoids the wait states and bus-turnaround penalties of asynchronous dual-port SRAMs. For designs that interleave read/write operations from two bus masters — think a DSP and an FPGA sharing a packet buffer — the 133 MHz clock keeps the arbitration latency under 7.5 ns per access. The parallel memory interface means all address, data, and control signals switch on the clock edge, so timing closure on the PCB is straightforward if the trace lengths are matched within a few hundred mils.","metaTitle":"CY7C0832AV-133AXC Cypress 4.5Mbit Dual-Port SRAM, 133 MHz","metaDescription":"Cypress CY7C0832AV-133AXC 4.5Mbit dual-port synchronous SRAM, 256Kx18, 133 MHz clock, 120-LQFP, 0°C–70°C.","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, Synchronous","Memory Size":"4.5Mbit","Memory Type":"Volatile","Memory Format":"SRAM","Mounting Type":"Surface Mount","Package / Case":"120-LQFP","Product Status":"Obsolete","Clock Frequency":"133 MHz","lifecycle_stage":"eol_hot","Memory Interface":"Parallel","Voltage - Supply":"3.135V ~ 3.465V","Base Product Number":"CY7C0832","Memory Organization":"256K x 18","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"120-TQFP (14x14)","Write Cycle Time - Word, Page":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is CY7C0832AV-133AXC obsolete?","answer":"Yes, the CY7C0832AV-133AXC is listed as Obsolete.
