Infineon Technologies S29GL01GT10DHI010

Overview

S29GL01GT10DHI010 from Infineon is a 1 Gb (128 MB) parallel NOR flash memory IC 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 industrial controllers requiring fast XIP execution and reliable non-volatile data retention.

For engineers reviewing the S29GL01GT10DHI010 datasheet, S29GL01GT10DHI010 pinout, S29GL01GT10DHI010 application, or S29GL01GT10DHI010 equivalent, key selection factors 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, supporting byte- and word-aligned addressing only. Its embedded algorithm controller (EAC) manages all program/erase operations autonomously, including automatic ECC generation and correction on read, status monitoring via Status Register/Data Polling/RY/BY# pin, and sector-level protection via volatile/non-volatile ASP.

The architecture includes dedicated address space overlays (ASOs) for Device ID/CFI, Status Register, Data Polling, SSR (OTP), ECC status, and sector protection control - enabling standardized firmware compatibility and secure one-time programmable configuration without external logic.

FAQ

What is the function of the RY/BY# pin on S29GL01GT10DHI010?

The RY/BY# pin is an open-drain output that signals operational status: low indicates an embedded program or erase operation is in progress, while high confirms readiness for the next command. It operates independently of Status Register polling and supports hardware flow control in real-time systems where deterministic timing is critical.

Does S29GL01GT10DHI010 support both ×8 and ×16 data bus configurations?

Yes - the device automatically detects bus width via the BYTE# signal (DQ15 in ×8 mode). When BYTE# is asserted low, it operates in ×8 mode with DQ0–DQ7 active; when high or unconnected, it defaults to ×16 mode using DQ0–DQ15. Address alignment remains byte- or word-boundary only in both modes.

How does the 512-byte write buffer improve programming efficiency?

The buffer allows up to 512 bytes (256 words) to be loaded before initiating a single embedded program operation, reducing command overhead and bus arbitration delays. Measured performance shows 1.14 MBps effective programming rate - more than 3× faster than sequential single-word programming under identical conditions.

Can the OTP array (SSR0–SSR3) be reprogrammed after initial programming?

No - the 2048-byte OTP array is permanently programmable once written. SSR0 is factory-locked and cannot be modified; SSR1 and SSR2 are user-lockable via command sequence; SSR3 supports password-based read protection but cannot be erased or rewritten. Locking is irreversible and enforced by on-chip logic.
