IS25LP256E-RMLA3 – Serial NOR Flash – ISSI

The ISSI IS25LP256E-RMLA3 is a 256 Mbit (32M x 8) automotive-grade serial NOR flash memory with QSPI/QPI and DTR support, supplied in a 16-pin SOIC (300 mil) package with a dedicated RESET# pin.

The ISSI IS25LP256E-RMLA3 is a high-performance 256 Mbit (32 Mbyte) serial NOR flash memory organized as 32M x 8. Part of Integrated Silicon Solution, Inc.’s (ISSI) IS25LP256E family, it operates from a 2.3 V to 3.6 V supply and is accessed through an industry-standard 4-wire SPI interface that can be configured for Dual I/O, Quad I/O, and QPI operation, plus Double Transfer Rate (DTR) commands for high read throughput.

The -RMLA3 suffix designates a 16-pin SOIC 300 mil package (M) with the dedicated RESET# option (R), RoHS-compliant (L) packaging content, in the A3 Automotive Grade (-40 °C to +125 °C), which meets AEC-Q100 requirements. This makes it well suited to automotive, industrial, and other harsh-environment code-storage applications.
