MX66L1G45G CMOS MXSMIO® Flash Memory

Macronix MX66L1G45G CMOS MXSMIO® (Serial Multi-I/O) Flash Memory are 1‑Gbit Serial NOR Flash memory devices featuring MXSMIO (Serial Multi‑I/O) technology. Internally, the Macronix MX66L1G45G is organized as 134,217,728 × 8-bits in single-I/O mode, while dual‑ and quad‑I/O modes reconfigure the memory to 536,870,912 × 2-bits and 268,435,456 × 4-bits, respectively. In single-I/O mode, the device operates over a simple three‑wire serial interface consisting of SCLK, SI, and SO, with CS# used to enable access.
