EN25T80-75QCP – 8Mbit Serial NOR Flash (SPI) – EON Silicon Solution (cFeon)

The EN25T80-75QCP is an 8 Mbit (1 MB) SPI Serial NOR Flash memory from EON Silicon Solution (cFeon) in an 8-pin SOP package, with a 75 MHz speed grade. A hard-to-find, obsolete BIOS/firmware storage device available for RFQ at Pacific Component Xchange.

The EN25T80-75QCP is an 8 Mbit (1,048,576 byte) uniform-sector Serial Flash memory manufactured by EON Silicon Solution Inc. under its cFeon brand. It is accessed through a high-speed, SPI-compatible serial bus and is widely used for non-volatile BIOS and firmware code storage. The device is supplied in an 8-pin SOP package (the “QCP” ordering code) and is rated for a 75 MHz speed grade (the “-75” suffix). Note: this part is sometimes mislabeled to other vendors such as ESMT or Cypress/Infineon, but the EN25T80 family is an EON Silicon Solution / cFeon product.

Key Features

• 8 Mbit (1 Mbyte) density — 4,096 programmable pages of 256 bytes each
• SPI-compatible serial interface with Dual Data mode
• Speed grade -75: serial clock up to 75 MHz (base EN25T80 device is rated to 100 MHz)
• Single power supply: 2.7 V to 3.6 V operation
• Uniform sector architecture: 256 sectors of 4 Kbyte and 16 blocks of 64 Kbyte
• Sector erase, block erase, and full chip erase support
• Endurance: minimum 100,000 program/erase cycles; 20-year data retention (125°C)
• Commercial and industrial temperature options (0°C to 70°C / -40°C to 85°C)
• 8-pin SOP (200 mil) package; “QCP” ordering code

Applications

• BIOS / boot code storage in PCs, motherboards, and embedded systems
• Firmware and configuration storage for networking and consumer electronics
• Set-top boxes, routers, and IoT devices
• Industrial control and embedded code-shadowing designs
