Product details

Overview

S29GL064N90FFI020 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory organized as 4,194,304 words (8,388,608 bytes), featuring 90 ns access time, 16-bit data bus with BYTE#-enabled 8-bit mode, and uniform sector architecture with 128 × 64 KB sectors. It supports in-system programming, hardware reset, and Secured Silicon Sector for factory- or customer-locked 256-byte electronic serial number storage - deployed in industrial control firmware storage and boot code retention.

For engineers reviewing the S29GL064N90FFI020 datasheet, S29GL064N90FFI020 pinout, S29GL064N90FFI020 application, or S29GL064N90FFI020 equivalent, key selection criteria include JEDEC-compliant command set compatibility, VIO-supported VersatileI/O™ (1.65–3.6 V), 100,000 erase cycles per sector, 20-year data retention, and support for Program/Erase Suspend & Resume operations across boot and main sectors.

Technical Context

This device implements a 110 nm MirrorBit floating-gate NAND-like cell architecture enabling simultaneous hot-hole erase and hot-electron program operations within discrete 64 KB sectors. Its command interface fully complies with JEDEC JESD21-C and supports CFI (Common Flash Interface) for host auto-identification.

The dual-voltage I/O architecture uses VIO to define all input thresholds and output drive levels independently of VCC (2.7–3.6 V), enabling interoperability with mixed-voltage microcontrollers. Hardware features include dedicated RY/BY# status pin, RESET# for operation termination, and WP#/ACC for accelerated programming and first/last sector write protection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Flash memory applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFI020	Same density and timing, but 56-pin TSOP package with different pinout (adds NC pins, relocates A16/A17); no Secured Silicon Sector	Lacks factory-programmed ESN and permanent lock capability - unsuitable for secure boot or device authentication	Select only when board layout requires 56-pin footprint and security features are unnecessary
MX29GL640EHT2I-90G	64 Mbit, 90 ns, 48-pin TSOP; Macronix part with identical JEDEC command set but no CFI support and no VIO pin	Requires fixed 3.3 V I/O; lacks VersatileI/O™ flexibility and CFI-based auto-detection - increases BSP porting effort	Choose only for cost-sensitive designs where mixed-voltage operation and bootloader automation are not required

Compared with S29GL064S90TFI020 and MX29GL640EHT2I-90G, the S29GL064N90FFI020 uniquely delivers Secured Silicon Sector + CFI + VIO-controlled I/O in a 48-pin TSOP, making it the only option supporting secure, auto-configurable, mixed-voltage boot memory in space-constrained industrial and automotive platforms.

FAQ

What is the function of the VIO pin on S29GL064N90FFI020?

The VIO pin sets the voltage threshold for all input signals (address, control, data) and defines output drive strength independently of VCC. With VIO ranging from 1.65 V to 3.6 V, it enables direct interfacing with 1.8 V, 2.5 V, or 3.3 V microcontrollers without external level shifters - a key enabler for mixed-voltage system design.

Does S29GL064N90FFI020 support both x8 and x16 data bus widths?

Yes. The BYTE# input selects between 16-bit (x16) and 8-bit (x8) data bus operation. When BYTE# is high, DQ0–DQ7 function as the lower byte; when low, all 16 bits (DQ0–DQ15) are active. This dual-mode capability ensures backward compatibility with legacy 8-bit controllers while supporting higher bandwidth in modern 16-bit interfaces.

How does the Secured Silicon Sector differ from standard flash sectors?

The Secured Silicon Sector is a dedicated 128-word (256-byte) region that can be permanently locked at the factory or by the user. Once locked, no further writes or erases are possible - even with elevated VPP. It contains an 8-word electronic serial number and is used for immutable device identification, secure boot key storage, and anti-counterfeiting in regulated industries.

Can S29GL064N90FFI020 perform read operations during erase or program suspend?

Yes. Both Erase Suspend and Program Suspend allow the host to pause an ongoing sector erase or program operation, then read or program any other unlocked sector. After completion, Erase Resume or Program Resume resumes the suspended operation. This enables concurrent firmware update and real-time data access without system stall - critical for deterministic response in industrial motion control.
