The Giga Device GD25Q128ESIGR is a 128Mb serial NOR flash memory in an 8-pin SOP package, operating from a 2.7V to 3.6V supply on a nominal 3V rail. It runs at clock frequencies up to 133M Hz and is rated over an industrial-adjacent temperature range of -40°C to 85°C. NOR flash supports random read access at the byte level, so a device such as the GD25Q128ESIGR can hold code that a host processor fetches directly. The part is RoHS compliant. Note that the interface type is not populated in this record.

The GD25Q128ESIGR is used as code and data storage in cost-sensitive embedded designs at the 128Mb density point. Common applications include boot firmware for microcontrollers and application processors, FPGA and CPLD configuration storage, router and IoT gateway firmware images, and non-volatile storage for fonts, graphics, look-up tables and event logs. The 8-pin SOP body and 133M Hz clock rating make it a widely used second-source alternative in consumer electronics, networking equipment, home appliances and industrial controllers. Buyers frequently qualify Giga Device serial NOR alongside equivalent-density parts from other suppliers to hold multiple sources on the same footprint.
