Product details
Overview
S29GL064S90TFI040 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory IC with 3.0 V single-supply operation, 70 ns access time, 128-word write buffer, and integrated hardware ECC for single-bit error correction. It features uniform 64-KB sectors, secure silicon region with factory-programmed 16-byte serial number, and operates across –40°C to +85°C industrial temperature range in 48-lead TSOP package.
For engineers reviewing the S29GL064S90TFI040 datasheet, S29GL064S90TFI040 pinout, S29GL064S90TFI040 application, or S29GL064S90TFI040 equivalent, this device supports boot code storage, firmware updates, and configuration data retention in embedded control systems requiring JEDEC-compliant, high-reliability parallel flash with persistent sector protection and erase suspend/resume capability.
Technical Context
The S29GL064S90TFI040 implements a 16-bit wide parallel interface with BYTE# input enabling optional 8-bit mode. Its MIRRORBIT™ 65-nm process enables simultaneous hot-hole erase and hot-electron programming across uniform 64-KB sectors.
It integrates on-die ECC logic that automatically detects and corrects single-bit errors during read operations, and supports command-set–compatible sector erase, program suspend/resume, and advanced protection via lock registers and password-controlled secure silicon region.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| S29GL064S90TFI020 | Same die, 90 ns access time (vs. 70 ns); identical pinout, package, and feature set | Lower performance margin for tight-timing boot paths; same endurance, ECC, and security features | Select when 90 ns meets system timing budget and cost optimization is prioritized |
| MX29GL640EHTI-90G | 64 Mb parallel NOR, 90 ns access, no on-die ECC; requires external error handling or host-level correction | Lacks hardware ECC and secure silicon region; not AEC-Q100 qualified | Choose only for cost-sensitive, non-safety-critical applications where ECC is managed externally |
Compared with S29GL064S90TFI040, the S29GL064S90TFI020 trades 20 ns speed for lower unit cost while retaining all reliability and security features, whereas MX29GL640EHTI-90G omits ECC and secure silicon-requiring host-side mitigation and excluding automotive or medical use.

FAQ
Is S29GL064S90TFI040 pin-compatible with earlier S29GL064N or S29GL064P variants?
No. S29GL064S90TFI040 uses the GL-S generation architecture with updated command set, enhanced ECC, and revised secure silicon implementation. While pinout matches 48-lead TSOP packages, differences in reset behavior, RY/BY# timing, and CFI query structure require firmware validation before drop-in replacement.
Does the Secure Silicon Region support customer programming after shipment?
Yes-customers can program and permanently lock the 128-word secure silicon region using the Enter Secure Silicon Region command sequence and PPB lock bit. Once locked, no further writes or erases are possible, even with elevated voltage on WP#/ACC.
What is the minimum VIO voltage supported for reliable 16-bit data transfer?
The minimum VIO voltage is 1.65 V, as specified in the datasheet. At this level, DQ0–DQ15 meet setup/hold timing requirements relative to OE# and WE# edges. Operation below 1.65 V risks metastability and data corruption during reads or writes.
Can Erase Suspend be used during Chip Erase mode?
No. Erase Suspend is supported only for Sector Erase commands. Chip Erase is an atomic operation with no suspend capability-interruption via RESET# aborts the entire erase and requires reinitialization.
