Infineon Technologies S29GL064S90TFI030

Overview

S29GL064S90TFI030 from Infineon is a 64 Mb (8 MB) parallel NOR flash memory with 3.0 V single-supply operation, 70 ns access time, 128-word write buffer, hardware ECC for single-bit correction, and industrial temperature range (–40°C to +85°C); used for boot code storage and firmware updates in embedded control systems.

For engineers reviewing the S29GL064S90TFI030 datasheet, S29GL064S90TFI030 pinout, S29GL064S90TFI030 application, or S29GL064S90TFI030 equivalent, key selection criteria include sector architecture (128 × 64-KB uniform sectors), VIO-controlled I/O compatibility (1.65 V to VCC), AEC-Q100 Grade 3 qualification, and Secure Silicon Region support for factory-programmed serial numbers.

Technical Context

This device implements MIRRORBIT™ floating-gate technology on a 65-nm process, enabling simultaneous hot-hole erase and hot-electron programming across uniform 64-KB sectors. It supports JEDEC-standard command sets including Unlock Bypass, Program/Erase Suspend/Resume, and CFI interrogation.

Hardware-level protection includes WP#/ACC pin-based first/last sector lock, low-VCC write inhibit, and RESET#-driven operation abort. The 128-word write buffer and 8-word read buffer reduce effective programming latency while maintaining full 16-bit bus width operation.

FAQ

Is S29GL064S90TFI030 pin-compatible with earlier S29GL064N or S29GL064P variants?

No. While functionally similar, S29GL064S uses updated 65-nm MIRRORBIT™ process and revised pin assignments for VIO and RESET# functionality. Pin mapping differs in TSOP packages - specifically, VIO replaces NC on pin 47, and RESET# moves from pin 44 to pin 45. Migration requires PCB layout revision.

Does the Secure Silicon Region support customer programming in-system?

Yes. The 128-word Secure Silicon Region can be programmed and locked either at factory or in-system using the Enter/Exit Secure Silicon Region command sequence. Once locked via PPB bit, no further writes or erases are possible - even with elevated VPP - ensuring permanent identity binding.

What is the role of the VIO pin beyond voltage level setting?

VIO defines both input logic thresholds and output drive strength. When VIO = 1.8 V, inputs recognize 0.9 V as logic high and outputs swing between 0 V and 1.8 V - enabling direct connection to 1.8 V FPGAs or ASICs without level shifters, while maintaining full 3.0 V core operation for reliability.

How does hardware ECC interact with the CFI query table?

Hardware ECC operates transparently during all read operations, including CFI table reads. The CFI data structure resides in fixed address space (0x0000–0x00FF) and is protected by the same on-die ECC engine - ensuring accurate identification of device parameters even after years of storage or under marginal voltage conditions.
