Description

W25Q01NWZEIM is a Winbond 1‑Mbit serial NOR flash memory in an 8‑pin package used for non‑volatile storage in embedded systems. Key points:
- Capacity: 1,048,576 bits (128 KB)
- Organization: 256‑byte pages; sectors 4 KB; blocks 32 KB and 64 KB
- Interface: SPI (SCK, SI, SO, CS); supports Read, Fast Read, Page Program (256 bytes), Sector/Block/Chip Erase; Write Enable/Disable and status/protection features
- Performance: Read up to ~104 MHz; includes power‑down and other low‑power modes
- Power: typically 2.7–3.6 V (variant specs may vary)
- Pinout: 8 pins (CS, SO, SI, SCK, WP#, HOLD#, VCC, GND)
- Applications: firmware/boot ROM, data logging, small embedded storage
Note: exact voltage range, temperature range, timing, and packaging depend on the specific variant; consult the official datasheet for precise specifications.

Note: exact timings and available features may vary by manufacturing lot and package variant.

Package

8-pin SOP (SOIC, SO-8) package.

Pinout

Pin count: 8 pins.
Function: Winbond W25Q01NWZEIM is a 1 Mbit serial SPI Flash memory used for code/data storage. It interfaces via SPI (CS, CLK, DI/SI, DO/SO) and includes WP# and HOLD# control pins, plus VCC and GND. It supports standard flash operations (read/fast-read, page program, sector/block erase, write enable).

Manufacturer

- Manufacturer: Winbond Electronics Corporation (Winbond)
- What kind of company: A Taiwanese semiconductor company and global memory IC maker, specializing in serial flash memory (and DRAM). It operates as an integrated device manufacturer (IDM) with its own fabrication facilities.
