概要

Description

GD25LR256EYIGR is a 256-Mbit serial flash memory from GigaDevice (GD). It stores code and data non-volatile and is accessed via a SPI-compatible interface (standard SPI; some variants support dual/quad I/O modes for higher speed). Operation voltage is typically 2.7–3.6 V (3.3 V nominal). It comes in an 8-pin, RoHS-compliant package (suffix IGR) and is suitable for firmware storage, boot ROMs, and data logging in embedded systems. Features usually include page-programming, sector/block/bulk erase, fast/read operations, and write-protection/security options. For exact timing, commands, and electrical characteristics, consult the GD25LR256 datasheet; the suffix denotes packaging and temperature range (industrial -40 to 85°C).

Features

GD25LR256EYIGR features (concise):
- 256-Mbit (32 MByte) serial flash memory.
- Supply voltage: 2.7V–3.6V (single‑I/O operation with low power modes).
- 8-pin SOP (IGR) package.
- SPI-compatible interface with Dual/Quad I/O and QPI support for higher throughput.
- Fast Read and Quad I/O Read modes (speed up to datasheet limits).
- Memory organization: 256-byte page, 4 KB sectors, 32 KB/64 KB blocks; Chip Erase option.
- JEDEC ID, Read ID and hardware/software protection features (BP bits, WP#).
- Deep power‑down mode and wake‑up support.
- Data retention and endurance: typical long-term retention with P/E cycling (industrial-grade reliability).
- Temperature range: -40°C to +85°C (industrial); RoHS compliant.
Note: exact speed figures and mode availability can vary by revision; consult the datasheet for precise timing and QE/enable requirements.

Package

8-pin SOP (SOP-8) package, RoHS-compliant lead-free.

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC‑8/WSON‑8).
- Function: 256‑Mbit serial SPI flash memory. Uses a standard SPI interface (CS, CLK, DI/MOSI, DO/MISO) plus WP# and HOLD# pins; power is provided by VCC and GND.

Manufacturer

- Manufacturer: GigaDevice Semiconductor Inc.
- What kind of company: A Chinese semiconductor company that designs and manufactures flash memory (NOR/NAND serial flash) and related microcontroller products.

Application

Typical application areas:
- Code storage and execution in microcontrollers/SoCs (bootloader, firmware)
- External flash for firmware updates and field upgrades (SPI/Quad SPI)
- Data logging and storage in IoT devices, wearables, industrial/medical systems
- Asset storage, configuration data, LUTs, buffers in consumer electronics and automotive ECUs
- High-density, low-power flash for embedded systems needing dual/quad SPI interfaces
