Product details

Overview

S25FL164K0XMFB011 from Cypress Semiconductor is a 64-Mbit (8 Mbyte), 3.0 V serial NOR flash memory with SPI Multi-I/O interface, supporting Quad Read at up to 108 MHz and 54 MB/s continuous data transfer. It features uniform 4 kB sector and 64 kB block erase, 100K program-erase cycles, 20-year data retention, and hardware/software write protection. Used for XIP code execution and firmware storage in space-constrained industrial controllers.

For engineers reviewing the S25FL164K0XMFB011 datasheet, S25FL164K0XMFB011 pinout, S25FL164K0XMFB011 application, or S25FL164K0XMFB011 equivalent, key selection criteria include Quad I/O timing compliance, security register OTP configuration, sector protection granularity, and migration path to S25FL064L for new designs.

Technical Context

This device implements JEDEC-standard SPI Multi-I/O (MIO) with configurable clock polarity/phase (modes 0 and 3), supporting Single, Dual, and Quad I/O protocols using shared IO0–IO3 pins. Command execution includes suspend/resume for both program and erase operations, enabling real-time host interrupt handling without data corruption.

The memory array uses 90 nm floating gate technology with a 2.7–3.6 V single supply. It integrates three 256-byte one-time-programmable (OTP) security registers, 8-byte unique ID, and pointer-based block protection - features confirmed for S25FL164K (not S25FL116K/S25FL132K), with AEC-Q100 Grade 2 qualification available.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial NOR flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S25FL064L0XMFI001	Successor device: 64 Mbit, 133 MHz Quad Read, 133 MB/s, 1.8 V / 3.0 V dual supply, 200K endurance, SFDP v1.6	Supports lower VCC (1.8 V) and higher speed; lacks Industrial Plus temp grade in same package; no HOLD#/WP# in Quad mode (shared pins)	Select for new designs requiring extended voltage range, higher throughput, or longer lifecycle; not drop-in due to command set extensions and voltage tolerance.
MX25L6433FZNI-10G	64 Mbit, 104 MHz Quad Read, 52 MB/s, 2.7–3.6 V, 100K endurance, standard SPI (no MIO), no OTP security registers	No suspend/resume, no SFDP, no unique ID, no pointer-based protection - minimal security and configurability	Select only where cost is primary constraint and security/XIP optimization are not required; requires custom driver development.

Compared with S25FL164K0XMFB011, S25FL064L offers higher speed and dual-voltage support but requires design migration, while MX25L6433F provides basic functionality at lower cost but omits critical features like OTP security, suspend/resume, and SFDP - making it unsuitable for safety- or security-sensitive applications.

FAQ

Is S25FL164K0XMFB011 still recommended for new designs?

No. Cypress explicitly states this part is "Not Recommended for New Design" and designates S25FL064L as the factory-recommended migration path. While fully functional and supported for existing production, new projects should adopt S25FL064L to ensure long-term supply, enhanced specs, and ongoing technical support.

What does the '0XMFB011' suffix indicate in the part number?

The suffix encodes package and temperature grade: '0X' = standard lead finish, 'MF' = 24-ball BGA (6 mm × 8 mm), 'B' = Industrial Plus temperature range (−40°C to +105°C), '011' = date code (2011 week 01). This matches FAB024/FAC024 package designation and +105°C qualification confirmed in the datasheet.

Can S25FL164K0XMFB011 operate in Quad I/O mode with hardware write protection enabled?

No. In Quad I/O mode, IO2 and IO3 are repurposed as Q2 and Q3 data lines, disabling WP# and HOLD# functions. Hardware write protection is only available in Single or Dual I/O modes. Software protection (via Status Register bits) remains active in all modes.

Does this device support JEDEC-standard Serial Flash Discoverable Parameters (SFDP)?

Yes. SFDP is implemented in Security Register 0 per JEDEC JESD216B, providing standardized, read-only parameter tables for clock frequency, latency, erase sizes, and command sets - enabling automatic driver initialization without hardcoded timing values.
