GD25Q40ETIGR

A: The device operates on a single voltage supply and has an industrial temperature rating. Key specifications are summarized in the table below: Specification Value Memory Density 4 Mbit (512K Bytes) Memory Organization 512K x 8-bit Memory Interface SPI (Standard, Dual, Quad I/O) Max Clock Frequency 133 MHz Supply Voltage (VCC) 2.7V to 3.6V Programming / Erase 400 µs typical (Page), 2.4ms max (Page) Data Retention 20 years Endurance 100,000 program/erase cycles Operating Temperature (Industrial) -40°C to +85°C Package 8-pin SOP-8 (150mil) RoHS Status ROHS3 Compliant, Pb-free

A: The GD25Q40ETIGR communicates using a standard 4-wire Serial Peripheral Interface (SPI) bus. The interface is configurable for three different modes for design flexibility. In Single SPI mode, it uses the SI (I/O0) and SO (I/O1) lines for command and data. For higher throughput, Dual SPI (using I/O0 & I/O1) and Quad SPI (using all I/O0, I/O1, I/O2, I/O3 lines) modes are supported, enabling data transfer speeds of up to 532Mbits/s. Additional control signals include CS# (Chip Select), HOLD# to pause ongoing serial communication, and WP# (Write Protect) to prevent accidental writes to critical memory regions.

A: The memory is designed for long-term reliability. The specifications include a minimum endurance of 100,000 program/erase cycles per sector. Furthermore, the device guarantees a minimum data retention period of 20 years at the maximum operating temperature, ensuring data integrity over the long term. It also supports low-power consumption features with a typical standby current of 11µA, making it suitable for battery-powered applications.

A: The status for this specific part number is contradictory. While the GD25Q40E family is in active mass production (Status MP) with several variants, multiple distributor sources have explicitly labeled the GD25Q40ETIGR as (This model is discontinued / Obsolete). Replacement / Alternative Options: Given the NRND and potential end-of-life status of the -TIGR package, design engineers are strongly advised to check for the most current lifecycle information with an authorized distributor. If a drop-in replacement is needed, the GD25Q40ETJGR is a viable alternative. The GD25Q40EEIGR is another option with similar specifications but in a different package (USON-8). For a general-purpose alternative in the same package, the GD25Q40CTIGR is widely available and an excellent choice.
