Infineon Technologies S29GL01GT10DHSS20

Overview

S29GL01GT10DHSS20 from Infineon is a 1 Gb (128 MB) parallel NOR flash memory using 45-nm MIRRORBIT™ technology, operating from 2.7 V to 3.6 V with 100 ns random access time and 15 ns page access time. It features a 512-byte write buffer, hardware ECC for single-bit correction, uniform 128-KB sector erase, and supports industrial temperature range (–40°C to +85°C). It is used in boot code storage for network routers requiring fast XIP execution and reliable non-volatile firmware retention.

For engineers reviewing the S29GL01GT10DHSS20 datasheet, S29GL01GT10DHSS20 pinout, S29GL01GT10DHSS20 application, or S29GL01GT10DHSS20 equivalent, key selection criteria include verified 100,000 program/erase cycles, 20-year data retention, CFI-compliant interface, OTP array with four lockable SSR regions, and support for suspend/resume during embedded operations.

Technical Context

This device implements an asynchronous parallel interface with ×8/×16 configurable data bus and byte/word boundary addressing. Its embedded algorithm controller (EAC) manages autonomous program and erase operations, while internal hardware ECC detects and corrects single-bit errors on-the-fly during read cycles.

The versatile I/O feature enables VIO operation from 1.65 V to VCC, decoupling I/O voltage from core supply. Sector protection includes volatile and non-volatile modes per 128-KB sector, and the 2048-byte OTP array provides factory-locked SSR0 and password-protected SSR3 for secure configuration storage.

FAQ

Is S29GL01GT10DHSS20 pin-compatible with earlier S29GL series devices?

Yes, it maintains identical 56-pin TSOP pinout and signal mapping with S29GL512T and S29GL01GP devices, including CE#, OE#, WE#, RY/BY#, and address/data bus assignments. However, the enhanced 45-nm process enables faster timing and lower power, so timing margins must be re-validated in legacy designs.

Does this device require an external VPP voltage for programming?

No. S29GL01GT10DHSS20 uses single-supply operation: VCC (2.7 V–3.6 V) powers both core logic and the memory array during read, program, and erase. No external high-voltage pump or VPP pin is present or required.

How is the OTP array protected against accidental overwrite?

The 2048-byte OTP array is divided into four 512-byte SSR regions (SSR0–SSR3). SSR0 is factory-locked permanently; SSR1 and SSR2 can be locked via command sequence; SSR3 supports password-based read protection. Once locked, no command can modify its contents.

Can S29GL01GT10DHSS20 operate with a 1.8 V I/O interface?

Yes. Its versatile I/O feature supports VIO from 1.65 V to VCC. When VCC = 3.3 V, VIO may be set to 1.8 V, enabling direct connection to 1.8 V SoC buses without level shifters-provided timing parameters (e.g., tOE, tCE) are met at that VIO level.
