Description

The W25R128JWPIQ is a Winbond 128-Mbit serial Flash memory (16 MB) in the W25R family. It provides non-volatile storage for embedded systems, suitable for firmware images, boot code, and data logging. Interface is SPI-compatible, with standard SPI read (and Fast Read) and optional dual/quad I/O or QPI modes depending on variant. Memory is organized in pages (commonly 256 bytes) and supports typical flash operations: page program, sector erase (4 KB), block erase (64 KB/256 KB), and chip erase. It includes protection and security features (write protection, status registers, and security IDs). The WPIQ suffix denotes a specific package and temperature grade; exact timing, voltage range, and mode support are specified in the datasheet. Common use cases include boot firmware storage, application code storage, and data storage in microcontroller-based designs. For precise specs, timings, and pinout, consult the Winbond W25R128JWPIQ datasheet.

Features

W25R128JWPIQ features (concise):
- 128 Mbit (16 MB) serial NOR flash memory.
- SPI interface with Quad I/O (QI/QPI) for higher throughput.
- Clock speeds: up to 104 MHz (SPI); Quad I/O/QPI up to similar high-speed operation.
- 24-bit addressing; 256-byte pages; erase sizes: 4 KB, 32 KB, 64 KB; bulk erase supported.
- Endurance approx. 100,000 program/erase cycles; data retention ~20 years.
- Supply voltage: 2.7–3.6 V (single 3V supply typical).
- Low-power modes including Deep Power-Down; fast wake and standby options.
- Security features: block protection with top/bottom protection, hardware write protect, status/configuration registers; 64-bit unique ID.
- Operating temp typically -40°C to 85°C (industrial); available in 8-pin package variants (PIQ).
- Applications: code storage and data storage in embedded systems requiring fast, dense, low-power flash.

Package

8-pin SOP (SOIC) package.

Pinout

Pin count: 8 pins (SOIC-8 / SOP-8 package).
Function: W25R128JWPIQ is a 128‑Mbit serial flash memory with SPI interface. Pinout (SOIC‑8):
- 1: /CS (Chip Select)
- 2: DO / MISO (data out)
- 3: WP# (Write Protect, active low)
- 4: GND
- 5: DI / MOSI (data in)
- 6: CLK (Serial Clock)
- 7: HOLD# (Hold, active low)
- 8: VCC (power)
It operates as non-volatile storage for code/data and supports standard SPI (and related modes) for read/write.
