IS25WP512M-JLLA3 – Serial NOR Flash – ISSI

The ISSI IS25WP512M-JLLA3 is a 512Mbit (64MB) 1.8V serial NOR Flash memory with multi-I/O SPI and QPI support, rated for automotive temperatures (-40C to +125C) in a WSON-8 package.

The IS25WP512M-JLLA3 from ISSI (Integrated Silicon Solution Inc.) is a high-density 512Mbit (64Mbyte) serial NOR Flash memory featuring an industry-standard SPI interface. The “WP” designation identifies the low-voltage 1.8V member of the IS25WP512M / IS25LP512M family, making it well suited to power-sensitive embedded designs that require a compact pin count and reliable code/data storage. This A3 automotive-grade version is qualified across the extended -40C to +125C temperature range.

The device supports flexible interface modes including Standard SPI, Fast Read, Dual, Dual I/O, Quad, Quad I/O, QPI, and Double Transfer Rate (DTR) operation, along with both 3-byte and 4-byte addressing to access the full 64MB address space. It is accessed through a 4-wire SPI interface (SI, SO, SCK, CE#) with additional pins reconfigurable for multi-I/O operation.
