IS25WP040E-JYLE-TR

Product Overview

The IS25WP040E-JYLE-TR from ISSI, Integrated Silicon Solution Inc is a 4Mbit serial flash memory device using NOR flash technology. It is organized as 512K x 8 and provides non-volatile storage for embedded systems that communicate with a host controller over SPI. The device supports SPI, Quad I/O, QPI, and DTR interface modes, with a clock frequency of 104 MHz and an access time of 8 ns. It operates from a 1.7V to 1.95V supply and over an ambient temperature range of -40°C to 105°C. The part uses a surface-mount 8-USON (2x3) package with an exposed pad, supporting compact board layouts.

• Systems using serial flash for data logging or lookup tables
• Compact electronic assemblies requiring a small surface-mount memory footprint

Design & Procurement Notes

When selecting this device, consider that the 4Mbit capacity and 512K x 8 organization define the addressable memory map, while the SPI, Quad I/O, QPI, and DTR interface options affect controller selection and signal routing. The 104 MHz clock frequency and 8 ns access time should be evaluated against the host controller timing requirements. The 1.7V to 1.95V supply range should be matched to the system power rail, and the 1.2 ms word/page write cycle time should be considered in firmware update routines. The 8-USON (2x3) exposed-pad package supports compact surface-mount layouts, but pad geometry and thermal relief should be checked against the board stackup and manufacturing process.
