Infineon Technologies S28HS01GTFPBHM033

Overview

S28HS01GTFPBHM033 from Cypress Semiconductor is a 1-Gb (128-MB) high-reliability NOR flash memory with Octal xSPI interface, operating at 1.7–2.0 V core/I/O (HS-T), housed in an 8×8 mm 24-ball BGA package. It delivers up to 400 MBps DDR read throughput, supports ISO 26262 ASIL-B compliance and ASIL-D readiness, and features EnduraFlex™ architecture for configurable endurance (2.56M program-erase cycles) and 25-year data retention - deployed in automotive ADAS ECUs and industrial safety controllers.

For engineers reviewing the S28HS01GTFPBHM033 datasheet, S28HS01GTFPBHM033 pinout, S28HS01GTFPBHM033 application, or S28HS01GTFPBHM033 equivalent, key selection criteria include octal DDR timing margin, SafeBoot initialization reporting, sector-level erase status tracking, and hardware reset via dedicated RESET# pin under AEC-Q100 Grade 1 (−40 °C to +125 °C) conditions.

Technical Context

This device implements Cypress's 45-nm MirrorBit® technology with dual-bit-per-cell storage and integrates two parallel controllers: Host Interface Controller (HIC) for SPI/OPI transaction handling and Embedded Algorithm Controller (EAC) for autonomous program/erase execution. It supports JEDEC JESD251-compliant xSPI protocols including both SDR and DDR octal modes.

The architecture includes on-die SECDED ECC, interface CRC, Data Integrity CRC, and SafeBoot diagnostics - all enabling functional safety-critical boot code storage. Its hybrid sector layout (32 × 4 KB + remainder 256 KB sectors) and programmable 256/512-byte page buffer allow flexible firmware partitioning and high-throughput updates in real-time systems.

FAQ

What is the maximum DDR read bandwidth supported by S28HS01GTFPBHM033?

The device achieves 400 MBps DDR read throughput at 200 MHz clock frequency using the octal 8D-8D-8D interface with Data Strobe (DS) synchronization. This performance is specific to the HS-T (1.8-V) variant and requires proper PCB layout for signal integrity, including matched trace lengths and controlled impedance for CK, DS, and DQ[7:0].

Does S28HS01GTFPBHM033 support both uniform and hybrid sector architectures?

Yes - it supports three configurations: uniform (all 256 KB sectors), hybrid configuration 1 (32 × 4 KB sectors grouped top or bottom), and hybrid configuration 2 (32 × 4 KB sectors split evenly top/bottom). The configuration is fixed at factory programming and cannot be changed in-system.

How does SafeBoot enhance system reliability during power-on?

SafeBoot performs self-checks on device initialization, verifies configuration register integrity, and detects corrupted SFDP or security settings. If faults are found, it enters recovery mode and signals via INT# or status registers - enabling host firmware to load fallback code or trigger diagnostic logging before normal operation begins.

Is the 1024-byte OTP array accessible for user-defined keys or certificates?

Yes - the OTP Secure Silicon array (32 × 32 bytes) is user-programmable once and supports storage of cryptographic keys, device identifiers, or calibration data. Programming is irreversible and requires specific command sequences; read access is unrestricted after programming, and the region is protected against accidental overwrite by hardware lock bits.
