128Mb, Multiple I/O Serial Flash Memory Features
Micron Serial NOR Flash Memory
1.8V, Multiple I/O, 4KB Sector Erase N25Q128A
Features
SPI-compatible serial bus interface 108 MHz (MAX) clock frequency 1.7–2.0V single supply voltage Dual/quad I/O instruction provides increased
throughput up to 432 MHz Supported protocols
– Extended SPI, dual I/O, and quad I/O Execute-in-place (XIP) mode for all three protocols
– Configurable via volatile or nonvolatile registers – Enables memory to work in XIP mode directly af-
ter power-on PROGRAM/ERASE SUSPEND operations Continuous read of entire memory via a single com-
mand – Fast read – Quad or dual output fast read – Quad or dual I/O fast read Flexible to fit application – Configurable number of dummy cycles – Output buffer configurable Software reset 64-byte, user-lockable, one-time programmable (OTP) dedicated area Erase capability – Subsector erase 4KB uniform granularity blocks – Sector erase 64KB uniform granularity blocks – Full-chip erase
Write protection – Software write protection applicable to every 64KB sector via volatile lock bit – Hardware write protection: protected area size defined by five nonvolatile bits (BP0, BP1, BP2, BP3, and TB) – Additional smart protections, available upon request
Electronic signature – JEDEC-standard 2-byte signature (BB18h) – Unique ID code (UID): 17 read-only bytes, including:
Two additional extended device ID (EDID) bytes to identify device factory options
