Product details
Overview
S25FL116K0XBHI033 from Cypress Semiconductor is a 16-Mbit (2 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Normal Read (50 MHz), Fast/Dual/Quad Read (108 MHz), and Execute-In-Place (XIP) operation. It features uniform 4-kB sector and 64-kB block erase, 100K program-erase cycles, and 20-year data retention - deployed in industrial control firmware storage and boot code execution.
For engineers reviewing the S25FL116K0XBHI033 datasheet, S25FL116K0XBHI033 pinout, S25FL116K0XBHI033 application, or S25FL116K0XBHI033 equivalent, key selection criteria include quad I/O read bandwidth (54 MB/s), security register OTP protection, SOIC-8 (208 mil) package compatibility, and migration path to S25FL064L for new designs.
Technical Context
This device implements JEDEC-standard SPI command set with support for modes 0 and 3, SFDP v1.5 compliance, and configurable volatile/non-volatile status registers. It uses 90 nm floating gate technology and supports hardware write protection via WP# and suspend/resume during program/erase operations.
The memory array is organized as 32 sectors × 64 kB, with dedicated 3 × 256-byte one-time-programmable (OTP) security registers. Quad I/O mode disables WP# and HOLD# functions, requiring software-based protection when enabled.
