GD25LD20CTIGR

Memory IC Overview

The GD25LD20CTIGR is a 2 Mbit NOR flash memory device manufactured by GigaDevice. It operates within a supply voltage range of 1.65 V to 2 V and utilizes an SPI interface with a maximum clock frequency of 50 MHz. The memory organization is 256 k x 8 bits, supporting an 8-bit data bus width. Active read current is specified at a maximum of 10 mA. The component is housed in an SOP-8 package (150mil) and is designed for industrial temperature ranges from -40°C to +85°C. It is supplied in tape and reel packaging.

Memory IC Feature Summary

• Supports low-voltage operation between 1.65 V and 2 V for power-constrained applications.
• Features uniform sector architecture compatible with standard SPI protocols.
• Designed for industrial environmental conditions across a wide temperature spectrum.

Memory IC Applications

• Industrial control systems requiring reliable non-volatile storage
• Low-power embedded devices operating on limited voltage supplies
• Firmware storage in consumer electronics with strict thermal requirements

Memory IC Procurement Notes

Verify the specific suffix 'C' indicates the correct voltage and temperature grade for your design. Confirm the SOP-8 150mil package dimensions match your PCB footprint. Ensure the manufacturing date code meets your project's shelf-life requirements. Check for RoHS compliance documentation if required by your region. Validate that the 1.8V supply rail aligns with the 1.65V to 2V operational window.

Memory IC Selection Notes

Select this part when a 2 Mbit capacity is needed with a 1.8V supply constraint. The SOP-8 package offers a balance of pin count and board space. The 50 MHz speed is suitable for moderate data throughput needs. Consider the industrial temperature rating for harsh environments. Compare against other GD25LD series variants if different packaging or voltage options are preferred.

Memory IC Part Context

This component belongs to the GD25LD20C series of NOR flash memories. It is distinct from higher-voltage variants like the GD25Q20C which operate at 3.3V. The 'I' suffix typically denotes industrial temperature range, while 'GR' indicates tape and reel packaging. It shares the core memory architecture with other members of the GD25LD family but differs in electrical specifications and physical form factor.

Memory IC Replacement Considerations

GD25LD20CUIGR offers identical electrical specifications but uses a USON-8 package instead of SOP-8. GD25LD20COIGR provides the same performance in an 8-TSSOP package. Verify pin compatibility and mechanical fit before substituting these alternatives.
