IS25WX256-LHLA3 – Serial NOR Flash (xSPI / Octal) – ISSI

The ISSI IS25WX256-LHLA3 is a 256Mbit (32M x 8) 1.8V xSPI Octal Serial NOR Flash with on-chip ECC, in a 24-ball TFBGA package, qualified to automotive temperature (-40C to +125C). Available now for RFQ.

The IS25WX256-LHLA3 from Integrated Silicon Solution Inc. (ISSI) is a high-performance 256 Megabit (32M x 8) Serial NOR Flash memory built on ISSI’s xSPI Octal Flash architecture. It implements the JEDEC Standard xSPI (eXpanded Serial Peripheral Interface) with integrated on-chip ECC, delivering fast, reliable code and data storage in a compact, low-pin-count package ideal for space-constrained embedded designs.

This specific orderable variant decodes as follows: IS25WX = 1.70V to 2.0V flash with OPI (Octal Peripheral Interface) and on-chip ECC; 256 = 256Mbit density; option L = Optional Read While Write (RWW); package H = 24-ball TFBGA (6x8mm, 5×5 ball array); L = Halogen-free / RoHS & TSCA compliant; and A3 = Automotive Grade (-40C to +125C), meeting AEC-Q100 requirements.

Key Features
