Infineon Technologies S29GL256S10TFIV10

Overview

S29GL256S10TFIV10 from Infineon is a 256 Mb (32 MB) parallel NOR flash memory IC with 16-bit data bus, fabricated on 65 nm MIRRORBIT™ Eclipse process. It operates from a single 2.7–3.6 V supply, delivers 90 ns random access time and 15 ns page access time, and integrates hardware ECC for single-bit error correction-enabling reliable code storage in automotive instrument clusters and industrial HMI boot memory.

For engineers reviewing the S29GL256S10TFIV10 datasheet, S29GL256S10TFIV10 pinout, S29GL256S10TFIV10 application, or S29GL256S10TFIV10 equivalent, this device supports asynchronous XIP-capable read, 512-byte buffer programming, uniform 128 kB sector erase, and AEC-Q100 Grade 3 qualification for automotive embedded systems requiring deterministic timing and long-term data retention.

Technical Context

The S29GL256S10TFIV10 implements an asynchronous parallel interface with word-aligned addressing (A0–A23), supporting both standard and page-mode reads. Its embedded algorithm controller (EAC) manages program/erase operations autonomously, including suspend/resume capability and status reporting via status register, data polling, or RY/BY# pin.

It features dual-voltage I/O (VIO = 1.65 V to VCC), enabling interoperability with mixed-voltage host systems. Internal hardware ECC corrects single-bit errors on-the-fly during read, while the 1024-byte OTP array provides secure storage for calibration data or security keys-both protected by advanced sector protection (ASP) with volatile/non-volatile lock options.

FAQ

What is the maximum operating frequency supported by the S29GL256S10TFIV10?

The S29GL256S10TFIV10 is an asynchronous parallel NOR flash and does not operate on a clock signal. Its performance is defined by access times: 90 ns random access and 15 ns page access. System timing depends on host controller setup/hold requirements and bus loading, not a fixed clock frequency. No maximum clock rate is specified because it uses address/data strobes (CE#, OE#, WE#) rather than synchronous clocking.

Does the S29GL256S10TFIV10 support burst read or sequential addressing?

No, the S29GL256S10TFIV10 does not support burst read or auto-increment addressing. It supports only asynchronous random and page-mode reads. In page mode, successive reads within the same 32-byte aligned page require only low-order address bits (A0–A3) to change, achieving 15 ns access-but each read remains individually strobed via CE# and OE#.

Can the OTP region be reprogrammed after locking?

No. Once a region of the 1024-byte OTP array is permanently locked using the appropriate unlock-bypass-lock command sequence, it cannot be reprogrammed or unlocked. The lock is irreversible and enforced by on-die fuses. Volatile locking (cleared on power cycle) is available for temporary protection during development, but permanent locking is one-time only.

Is the S29GL256S10TFIV10 compatible with 1.8 V I/O interfaces?

Yes. The versatile I/O feature allows VIO to operate from 1.65 V to VCC. When VCC = 3.3 V, VIO can be set to 1.8 V, enabling direct connection to 1.8 V host processors without level shifters. Signal thresholds and timing parameters (e.g., tOE = 35 ns in VersatileIO mode) are guaranteed across the full VIO range per datasheet Section 11.4.
