Infineon Technologies S29GL01GT11TFIV33

Overview

S29GL01GT11TFIV33 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 sectors, 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 S29GL01GT11TFIV33 datasheet, S29GL01GT11TFIV33 pinout, S29GL01GT11TFIV33 application, or S29GL01GT11TFIV33 equivalent, key selection factors include parallel ×16 bus interface timing compliance, sector erase endurance (100,000 cycles), OTP array configuration (SSR0–SSR3), ASP protection granularity, and CFI-compliant software interface support.

Technical Context

This device implements an asynchronous parallel interface with byte/word boundary addressing and supports both 8-bit and 16-bit data bus configurations. Its embedded algorithm controller (EAC) manages program, erase, and suspend/resume operations autonomously without external intervention.

The internal hardware ECC engine performs real-time single-bit error correction during read operations and reports multi-bit errors via status register flags. Sector protection uses volatile (lock bits) and non-volatile (ASP) methods, with four lockable 2048-byte OTP regions - SSR0 factory-locked, SSR3 password-read-protected.

FAQ

Does S29GL01GT11TFIV33 support both ×8 and ×16 data bus modes?

Yes, it supports configurable ×8 or ×16 operation via hardware pin strapping (BYTE# signal). When BYTE# is low, the device operates in ×16 mode with DQ0–DQ15 active; when high, it operates in ×8 mode with DQ0–DQ7 only. This allows flexible integration with 8-bit or 16-bit microcontroller buses without external glue logic.

What is the function of the SSR0–SSR3 OTP regions?

SSR0–SSR3 are four 2048-byte one-time-programmable arrays. SSR0 is factory-locked and contains immutable security keys; SSR1–SSR2 are user-lockable for calibration data; SSR3 supports password-based read protection. Once programmed and locked, contents cannot be erased or rewritten, ensuring tamper-resistant storage of critical parameters.

How does the Ready/Busy# (RY/BY#) pin behave during erase operations?

RY/BY# goes low at the start of any embedded operation (program or erase) and remains low until completion. During sector erase, it stays asserted for up to 1.5 seconds (typical), signaling active internal state machine execution. The pin is open-drain and requires an external pull-up resistor; its transition to high confirms readiness for the next command without polling.

Is CFI support mandatory for driver compatibility?

CFI support is not mandatory but strongly recommended: it provides standardized register maps for automatic identification of geometry, command sets, and timing parameters. Without CFI, drivers must be hardcoded for this specific part, increasing porting effort and limiting reuse across flash families. All GL-T devices implement full CFI v1.3 compliance per JEDEC JESD68.
