The 𝗫𝗠𝟮𝟱𝗟𝗨𝟲𝟰𝗖 (𝟲𝟰𝗠-𝗯𝗶𝘁) Serial Flash is a compact, low-power memory solution designed for space-constrained systems. It operates on 1.65V–2.0V with ultra-low 0.2µA deep power-down current and supports SPI, Dual/Quad SPI, and QPI interfaces up to 133MHz (higher effective speeds in Dual/Quad modes).

Organized into 256-byte pages, it supports 4KB, 32KB, 64KB, and full-chip erase options for flexible data storage. It also features DTR support, Continuous Read (XIP), programmable write protection, JEDEC ID, SFDP, a 128-bit unique ID, and security registers.
