Product details

Overview

S29GL064N90FFI032 from Infineon Technologies (formerly Cypress) is a 64 Mbit, 3.0 V single-power-supply MirrorBit Flash memory IC organized as 4,194,304 words × 16 bits, 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 in industrial temperature range (–40°C to +85°C) for embedded boot code and firmware storage in networking equipment.

For engineers reviewing the S29GL064N90FFI032 datasheet, S29GL064N90FFI032 pinout, S29GL064N90FFI032 application, or S29GL064N90FFI032 equivalent, key selection criteria include JEDEC-compliant command set, Secured Silicon Sector with factory-programmed 128-word ESN, flexible 16-bit/8-bit bus configuration via BYTE#, and hardware-accelerated programming via WP#/ACC input.

Technical Context

This device implements a NOR Flash architecture with hot-electron injection programming and hot-hole assisted erase, enabling byte/word-level random read and sector-level erase. Its VersatileI/O™ control decouples I/O voltage (VIO = 1.65–3.6 V) from core supply (VCC = 2.7–3.6 V), supporting mixed-voltage system interfacing.

The command-set architecture includes CFI compliance for automatic device identification, Program/Erase Suspend & Resume for concurrent operations, and Advanced Sector Protection with both Persistent and Password-based locking modes. The Secured Silicon Sector provides a dedicated 256-byte region with permanent factory or customer lockability.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
S29GL064S90TFI020	Same density and speed, but 56-pin TSOP package; no Secured Silicon Sector; VIO range limited to 2.7–3.6 V.	Lacks factory-programmed ESN and persistent lock capability; unsuitable for secure boot or device ID binding.	Select when footprint compatibility with 56-pin layout is required and security features are not mandated.
MX29GL640EHTI-90G	64 Mbit, 90 ns, Macronix part; supports CFI and sector protection but uses different command set; no WP#/ACC acceleration pin.	Requires modified driver layer due to non-Cypress command timing; lacks hardware-accelerated programming for production lines.	Choose for cost-sensitive designs where firmware update frequency is low and driver porting effort is acceptable.

Compared with S29GL064S90TFI020 and MX29GL640EHTI-90G, the S29GL064N90FFI032 uniquely combines industrial temperature rating, Secured Silicon Sector with ESN, and WP#/ACC hardware acceleration-making it optimal for secure, high-throughput, field-upgradable embedded systems.

FAQ

What is the function of the WP#/ACC pin on S29GL064N90FFI032?

The WP#/ACC pin serves dual functions: when held low, it hardware-protects the first or last sector regardless of software protection settings; when driven to VCC + 2.5 V (within absolute max rating), it enables accelerated programming for faster production throughput. This pin is electrically isolated from VCC and requires external voltage boosting circuitry for ACC mode.

Does S29GL064N90FFI032 support 8-bit data bus operation?

Yes, the device supports 8-bit operation via the BYTE# pin: when BYTE# is high, only DQ0–DQ7 are active and DQ8–DQ15 are tri-stated, enabling x8 mode. Address lines remain unchanged, and the internal memory array is accessed as 8,388,608 bytes. This mode is fully compliant with JEDEC standard pinout and command definitions.

How is the Secured Silicon Sector protected and accessed?

The Secured Silicon Sector is a dedicated 256-byte region (128 words) accessible only through a specific unlock-bypass command sequence. It contains a factory-programmed 16-byte Electronic Serial Number and can be permanently locked by setting the PPB lock bit. Once locked, no further writes or erases are possible-even with valid commands-ensuring immutable device identity.

Can S29GL064N90FFI032 be used in systems with 1.8 V I/O interfaces?

Yes, provided VIO is supplied at 1.8 V and VCC remains within 2.7–3.6 V. The VersatileI/O™ architecture ensures all input thresholds and output drive levels scale with VIO, allowing direct connection to 1.8 V FPGAs or ASICs without level shifters. However, the minimum VIO is 1.65 V, and AC timing parameters must be verified per the datasheet's VIO-dependent tables.
