Infineon Technologies S26HL02GTFGBHB043

Overview

S26HL02GTFGBHB043 from Infineon Technologies is a 2 Gb (256 MB) SEMPER™ NOR Flash memory with HYPERBUS™ DDR interface, 1.8 V core supply (HS-T grade), 24-ball BGA package, and ISO 26262 ASIL-B compliance for automotive safety-critical boot code storage in ADAS ECUs.

For engineers reviewing the S26HL02GTFGBHB043 datasheet, S26HL02GTFGBHB043 pinout, S26HL02GTFGBHB043 application, or S26HL02GTFGBHB043 equivalent, this device delivers 332 MBps read throughput via HYPERBUS™ DDR at 166 MHz, supports dual-die package (DDP), includes on-chip ECC (SECDED), OTP secure silicon region (1024 bytes), and hybrid sector architecture with thirty-two 4 KB sectors.

Technical Context

This device implements Infineon's 45-nm MIRRORBIT™ technology with two bits per cell, enabling high-density NOR Flash in a multi-chip package. It supports both legacy ×1 SPI (SDR, up to 20.75 MBps) and HYPERBUS™ ×8 DDR (up to 332 MBps), with data strobe (DS) synchronized to CK/CK# for precise high-speed read capture.

The architecture includes configurable page programming buffers (256 B or 512 B), uniform or hybrid sector layouts (4 KB top/bottom + 256 KB main), and functional safety features: SafeBoot initialization reporting, interface/data integrity CRC, and built-in SECDED ECC correcting single-bit errors and detecting double-bit errors in the memory array.

FAQ

What interface modes does S26HL02GTFGBHB043 support, and how are they selected?

The device supports both legacy ×1 SPI (SDR) and HYPERBUS™ ×8 DDR interfaces. Interface selection is determined by hardware configuration at power-on: default boot uses SPI unless HYPERBUS™ is enabled via SFDP register settings or factory configuration. No external mode pins are required - the host controller initiates the desired protocol after reset.

Does S26HL02GTFGBHB043 require external ECC handling by the host processor?

No. The device integrates on-die SECDED (Single Error Correction, Double Error Detection) logic that automatically corrects single-bit errors and flags double-bit errors during read operations. Host software only needs to monitor status registers for uncorrectable errors; no external ECC computation or buffering is required.

How is the hybrid sector architecture configured - is it fixed or programmable?

The sector architecture is factory-configured and fixed per part number: S26HL02GTFGBHB043 implements the hybrid split configuration - thirty-two 4 KB sectors at both top and bottom of address space, with remaining regions as 256 KB sectors. This layout cannot be altered in-system and is defined in the SFDP parameter table.

What is the role of the RSTO# pin, and can it drive an external microcontroller reset?

RSTO# is an open-drain output that asserts LOW during internal power-on reset (POR) and releases to high-impedance after a user-defined timeout. With an external pull-up resistor, it transitions HIGH to signal reset completion. It is designed to synchronize system-level reset sequencing and can directly drive compatible MCU reset inputs when properly terminated.
