This is the timing parameter that governs read and write cycle compatibility with your processor or FPGA memory controller. A 55 ns access time means the data is valid on the bus within 55 ns of the address being stable — critical for meeting setup and hold times on a 16-bit data bus running at moderate clock rates. For a typical 8 MHz to 12 MHz microcontroller or a medium-speed DSP, this part fits without wait-state insertion. The 512K-word depth (8 Mbit total) provides 1 MB of byte-addressable storage, sized for boot code, lookup tables, or frame buffers in embedded systems. This is a straightforward fit for production BOMs and new designs that need a reliable parallel SRAM source. No need to qualify a substitute or stockpile ahead of a phase-out window. ## Peer variant — M5M5W816WG-70HI#BT The same Mitsubishi SRAM family includes the M5M5W816WG-70HI#BT, which differs only in access time: 70 ns versus the 55 ns of this part. For systems that can tolerate the slower access, the 70 ns variant offers a cost-reduction path or a second-source option without changing footprint or pinout. The 55 ns part gives tighter timing margin on a faster bus, while the 70 ns version may be adequate for slower controllers or when derating for temperature is less critical.","metaTitle":"Mitsubishi M5M5W816WG-55HI#BT Standard SRAM, 512Kx16, 55 ns","metaDescription":"Mitsubishi M5M5W816WG-55HI#BT standard SRAM, 512Kx16 organization, 55 ns access time, active lifecycle.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$14.52","stockQuantity":0,"priceTiers":[{"qty":21,"price":"$14.52000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d36f02f14139f2c03d80a5f41ca1c218.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the access time of M5M5W816WG-55HI#BT?","answer":"The access time is 55 ns, as indicated by the -55 suffix in the order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/M5M5W816WG-55HIBT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/M5M5W816WG-55HIBT when reusing this data.
