25Q32 Flash Memory 32Mbit 4MB SOIC-8 SMD
The 25Q32 Flash Memory 32Mbit 4MB SOIC‑8 SMD is a high‑performance Serial NOR Flash memory device designed for compact systems requiring robust non‑volatile storage. Offering 32Mbits (4MBytes) of memory capacity, this device is suitable for a wide range of embedded applications where reliable code, data, or configuration storage is necessary. It implements a Serial Peripheral Interface (SPI) protocol that supports standard SPI as well as Dual and Quad SPI modes to achieve higher data throughput and faster access times.
Features:
- 32M-bit (4MB) storage capacity with 4KB uniform sectors for efficient erase operations.
- Supports standard SPI, Dual SPI, and Quad SPI interfaces for high-speed data transfer.
- Maximum clock frequency of 133MHz with equivalent rates up to 532MHz in Quad mode.
- Low power consumption with less than 1μA in power-down mode.
- Minimum 100,000 program/erase cycles per sector and over 20 years of data retention.
- Flexible erase options including 4KB sector, 32KB block, 64KB block, and full chip erase.
