Product details

Overview

S29GL064N90FFIS33 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words (16-bit bus), featuring 90 ns access time, 100,000 erase cycles per sector, and 20-year data retention. It supports uniform sector architecture with 128 × 64 KB sectors and operates across VCC = 2.7–3.6 V and VIO = 1.65–3.6 V, deployed in industrial control firmware storage and boot code retention.

For engineers reviewing the S29GL064N90FFIS33 datasheet, S29GL064N90FFIS33 pinout, S29GL064N90FFIS33 application, or S29GL064N90FFIS33 equivalent, key selection criteria include JEDEC software compatibility, Secured Silicon Sector with factory-programmed 128-word ESN, Advanced Sector Protection (Persistent and Password modes), and dual-bus capability via BYTE# control for 8/16-bit system integration.

Technical Context

This device implements a command-set-compatible NOR Flash architecture with hardware reset (RESET#), ready/busy status signaling (RY/BY#), and VIO-referenced I/O voltage scaling. Its 110 nm MirrorBit process enables hot-hole assisted erase and hot-electron injection programming, supporting both chip- and sector-erase operations with suspend/resume capability.

The memory uses separate CE#, WE#, and OE# controls for precise bus timing, integrates CFI (Common Flash Interface) for host auto-identification, and includes on-chip voltage detection to inhibit writes during power transitions. The WP#/ACC pin provides accelerated programming and hardware write protection for first/last sector regardless of software protection settings.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFIV10	Same density and speed, but 56-pin TSOP package with different pinout (e.g., NC pins at positions 1–2, 55–56); no BYTE# pin	Requires PCB redesign; lacks byte-width flexibility; suited for fixed 16-bit-only designs	Select when board layout accommodates 56-pin footprint and system does not require 8-bit bus mode
MX29GL640EHT2I-90G	64 Mbit, 90 ns, but uses Macronix's MX29GL architecture; no Secured Silicon Sector; CFI implementation differs in vendor-specific extensions	Missing factory-programmed ESN and persistent lock bits; unsuitable for secure boot or device authentication	Select only for cost-sensitive, non-security-critical applications where CFI basic functionality suffices

Compared with S29GL064S90TFIV10 and MX29GL640EHT2I-90G, the S29GL064N90FFIS33 uniquely delivers Secured Silicon Sector with ESN, BYTE#-enabled bus flexibility, and full suspend/resume support-making it the only choice for secure, field-upgradable embedded systems requiring long-term data integrity and mixed-bus compatibility.

FAQ

Is S29GL064N90FFIS33 pin-compatible with earlier S29GL064N variants in 48-pin TSOP?

Yes - S29GL064N90FFIS33 uses the same 48-pin TSOP footprint and pinout as documented in Figure 1 of datasheet 001-98525 Rev. *B, including identical A0–A21, DQ0–DQ15, CE#, WE#, OE#, BYTE#, WP#/ACC, RY/BY#, RESET#, VIO, VCC, and VSS assignments. No PCB change is required for drop-in replacement.

Does this device support true 8-bit data bus operation?

Yes - when BYTE# is driven high, the device operates in 8-bit mode using DQ0–DQ7 only, with DQ8–DQ15 disabled. Address lines remain fully functional, and all commands, protection features, and timing parameters retain specification compliance in this mode.

What is the function of the WP#/ACC pin during normal operation versus programming acceleration?

In normal operation, WP# = low protects the first or last sector from program/erase regardless of software protection settings. During accelerated programming, ACC = high (with VCC ≥ 3.0 V) enables higher internal programming voltage, reducing typical word-program time from 1.4 µs to 0.8 µs - intended for high-throughput manufacturing.

Can the Secured Silicon Sector be reprogrammed after factory locking?

No - once the Secured Silicon Sector is permanently locked (via PPB lock bit or factory fuse), no further writes or erases are possible, even with correct password or elevated voltage. The 8-word Electronic Serial Number is programmed and locked at the factory and cannot be altered in the field.
