CY62146EV30LL-45BVXI

CY62146EV30LL-45BVXI is a Cypress (now Renesas) static RAM device. It’s a high‑speed, single‑port RAM used for buffering, caches, and frame buffers in embedded systems.
Key points:
- Type: SRAM (static RAM), not DRAM or FLASH.
- Capacity/organization: 4‑Mbit class family; available in common x8/x16 data-bus options (density shown by the exact variant).
- Speed: 45 ns access time (you’ll see -45 in the part number).
- Voltage: typically 2.7–3.6 V operation.
- Package: LL leadless/package variant with BVXI pinout; supports standard memory control pins (CE, OE, WE) and data I/O.
- Applications: high‑speed buffering, cache memory, graphics/frame buffers in embedded/industrial systems.
For exact memory organization, pinout, electrical specs, and recommended operating conditions, refer to the official datasheet for CY62146EV30LL-45BVXI.

Equivalents depend on capacity, bus width and voltage. CY62146EV30LL-45BVXI is a 4-Mbit SRAM (32-pin, 3.3V, 45ns). Cross-refs from other vendors (same density/interface) typically appear in ISSI, Renesas, Micron lines for 4Mbit, 32-pin, 3.3V parts. Use Cypress cross-reference tool for exact numbers.
