IS25WP016D-JNLE-TR

IS25WP016D-JNLE-TR is a 16-Mbit serial NOR flash memory from ISSI. It provides SPI-compatible storage for firmware and data in embedded systems, with support for standard SPI as well as Dual/Quad I/O modes for higher throughput. Key features typically include: non-volatile storage, page-program and sector/block erase, fast read, and write/hold protection options. It operates at low voltage (around 2.7–3.6 V) and is designed for industrial temperature ranges (-40°C to +85°C). The -TR suffix indicates Tape & Reel packaging, while JNLE denotes the device variant/temperature grade and package type. It is offered in an 8-pin package suitable for compact embedded designs and is ideal for boot memory, firmware updates, and configuration storage.
