Infineon Technologies S29GL01GT12TFM020

Overview

S29GL01GT12TFM020 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, and uniform 128-KB sector erase-designed for boot code storage in industrial microcontroller-based systems requiring high reliability and fast XIP execution.

For engineers reviewing the S29GL01GT12TFM020 datasheet, S29GL01GT12TFM020 pinout, S29GL01GT12TFM020 application, or S29GL01GT12TFM020 equivalent, key selection criteria include its 128-KB uniform sector architecture, Versatile I/O support (1.65 V–VCC), AEC-Q100 Grade 2 qualification (–40°C to +105°C), and CFI-compliant interface for firmware update compatibility.

Technical Context

This device implements an asynchronous parallel interface with ×8/×16 data bus configuration and supports byte/word boundary addressing only. Its embedded algorithm controller (EAC) manages program, erase, suspend/resume, and automatic ECC operations without host CPU intervention.

The status monitoring uses three concurrent methods: Status Register polling, Data Polling (DQ7), and RY/BY# pin assertion-enabling deterministic timing control in real-time boot loaders and firmware recovery sequences.

FAQ

What is the maximum operating temperature range for S29GL01GT12TFM020?

The S29GL01GT12TFM020 is rated for –40°C to +105°C and qualified to AEC-Q100 Grade 2. This rating is verified per Infineon's datasheet Rev. *M (2022-07-25), Section "Temperature range / grade", and applies to all electrical and timing specifications listed under that grade. No derating is required within this range.

Does this part support both ×8 and ×16 data bus modes?

Yes, S29GL01GT12TFM020 supports configurable ×8 or ×16 operation via hardware pin strapping (BYTE# input). In ×16 mode, DQ15–DQ0 transfer 16-bit words; in ×8 mode, DQ7–DQ0 transfer bytes with DQ15–DQ8 unused. Mode selection is determined at power-up and remains fixed until reset.

Is hardware ECC enabled by default, and can it be disabled?

Hardware ECC is always active during read operations and cannot be disabled. The ECC logic operates transparently in the data path: single-bit errors are corrected automatically, and uncorrectable multi-bit errors trigger the Status Register's ECC Error bit (SR[6]). No host initialization or register writes are needed to activate ECC.

What package type does S29GL01GT12TFM020 use, and what is its ball pitch?

S29GL01GT12TFM020 uses a 64-ball LAE fortified BGA package measuring 9 mm × 9 mm with 0.8 mm ball pitch. This is confirmed in Infineon's datasheet Rev. *M, Section "12.2 64-ball FBGA", and distinguishes it from the 64-ball LAA (13 mm × 11 mm) and 56-ball VBU variants.
