Infineon Technologies S29GL128S90TFI013

Overview

S29GL128S90TFI013 from Infineon is a 128 Mb (16 MB), 3.0 V core, parallel-interface MIRRORBIT™ Eclipse flash memory with ×16 data bus, 90 ns random access time, 15 ns page access time, and industrial temperature grade (–40°C to +85°C). It integrates hardware ECC for single-bit error correction, 128-kbyte uniform sector erase, and a 512-byte programming buffer - deployed in boot code storage for industrial HMIs and firmware update storage in network edge routers.

For engineers reviewing the S29GL128S90TFI013 datasheet, S29GL128S90TFI013 pinout, S29GL128S90TFI013 application, or S29GL128S90TFI013 equivalent, key selection criteria include asynchronous parallel interface timing compliance, OTP array availability for secure configuration, sector protection granularity, and Versatile I/O voltage range (1.65 V to VCC) for mixed-voltage system integration.

Technical Context

This device implements an asynchronous parallel NOR flash architecture with XIP-capable read performance: initial random access reads a full 32-byte aligned page, followed by 15 ns sub-page accesses within the same page using low-order address bits only. The embedded algorithm controller (EAC) manages all program/erase operations, including suspend/resume and status reporting via status register, data polling, or RY/BY# pin.

It features dual-voltage operation: 2.7–3.6 V core supply (VCC) powers all functions (read/program/erase), while I/O voltage (VIO) ranges independently from 1.65 V to VCC - enabling direct interfacing with 1.8 V, 2.5 V, or 3.3 V controllers without level shifters. Internal hardware ECC operates transparently during read cycles.

FAQ

Does S29GL128S90TFI013 support both 1.8 V and 3.3 V I/O interfaces?

Yes. Its Versatile I/O feature allows VIO to operate from 1.65 V to VCC, enabling direct connection to 1.8 V logic (e.g., FPGA banks) or 3.3 V microcontrollers without level shifters. VCC must remain within 2.7–3.6 V, and VIO must not exceed VCC. This dual-voltage flexibility is confirmed in Section 8.3 of the datasheet and validated across all industrial temperature ranges.

Can the OTP array be reprogrammed after locking?

No. The 1024-byte OTP array has two lockable regions; once a region is permanently locked via the appropriate command sequence (0x60 → 0xD0), its contents become read-only and cannot be altered, erased, or reprogrammed - even with power cycle or reset. This behavior is hardware-enforced and documented in Section 3.3 and Table 7-1 of the datasheet.

What is the maximum sustained programming throughput using the 512-byte buffer?

At rated conditions (VCC = 3.0 V, TA = 25°C), the buffer programming rate is 1.5 MBps - meaning a full 512-byte buffer writes in ~340 µs. This value is measured under optimal timing and excludes command overhead; actual system throughput depends on host bus arbitration and CE#/WE# setup/hold compliance per AC specification table (Section 11.4).

Is the RY/BY# pin electrically compatible with 1.8 V logic inputs?

Yes. RY/BY# is an open-drain output referenced to VIO, so when VIO = 1.8 V, its low-state voltage is <0.4 V and high-state is pulled up externally to 1.8 V - fully compatible with 1.8 V CMOS input thresholds. The datasheet specifies VOL ≤ 0.4 V and recommends a 4.7 kΩ pull-up to VIO for reliable operation across temperature.
