IS25WP016D-JULA3-TR – Serial NOR Flash – ISSI

The ISSI IS25WP016D-JULA3-TR is a 16Mbit (2MB) 1.8V serial NOR flash memory with a 133MHz multi-I/O SPI / Quad I/O QPI interface in an 8-pin USON (2x3mm) package, supplied on tape and reel. Available now for RFQ.

The IS25WP016D-JULA3-TR from ISSI (Integrated Silicon Solution, Inc.) is a 16Mbit (2Mbyte) serial NOR flash memory device built for space-constrained, low-pin-count, low-power embedded systems. The “W” designation indicates a low-voltage 1.65V to 1.95V (nominal 1.8V) supply, while the “JU” suffix denotes the compact 8-pin USON 2x3mm package. The “A3” grade marks this as an ISSI automotive-grade part, and the “-TR” suffix indicates tape-and-reel packaging for automated assembly.

This device belongs to the IS25WP016D / IS25LP016D 16Mb serial flash family and is accessed through a 4-wire SPI interface (SI, SO, SCK, CE#) that can be reconfigured for multi-I/O operation. It supports a broad range of interface modes including standard SPI, Fast Read, Dual Output, Dual I/O, Quad Output, Quad I/O, SPI DTR, Dual I/O DTR, Quad I/O DTR, and QPI, giving designers flexibility to trade throughput against pin usage.
