IS25WP040D-JULA3-TR – Serial NOR Flash – ISSI
The IS25WP040D-JULA3-TR is an ISSI 4Mbit (512KB) automotive-grade serial NOR flash memory with a 1.65V-1.95V supply, 133MHz multi-I/O SPI / QPI DTR interface, in an 8-contact USON 2x3mm package, supplied on tape and reel.
The IS25WP040D-JULA3-TR from ISSI (Integrated Silicon Solution, Inc.) is a 4Mbit (512Kbyte) low-voltage serial NOR flash memory from the IS25WP family. Designed for space-constrained, low-pin-count, low-power embedded systems, it is accessed through a standard 4-wire SPI interface (SI, SO, SCK, CE#) that can also be configured for Dual and Quad I/O as well as QPI operation. With clock frequencies up to 133MHz and Double Transfer Rate (DTR) support, it delivers high effective throughput (up to a 532MHz equivalent data rate), enabling efficient code shadowing and execute-in-place (XIP) operation.
The “A3” suffix designates this as an Automotive Grade device rated from -40°C to +125°C and meeting AEC-Q100 requirements, making it well suited to harsh-environment and long-lifecycle designs.
