Infineon Technologies S28HS01GTFPBHB033

Overview

S28HS01GTFPBHB033 from Cypress Semiconductor (now Infineon) is a 1-Gb (128-MB), 1.8-V HS-T Semper® Flash NOR memory with Octal xSPI interface, supporting DDR read up to 400 MBps and featuring ISO 26262 ASIL-B compliance, EnduraFlex™ endurance partitioning, and SECDED ECC. It implements 45-nm MirrorBit® technology with hybrid sector architecture (thirty-two 4 KB sectors + remaining 256 KB sectors) and is used in automotive ADAS ECUs for boot code storage and firmware updates.

For engineers reviewing the S28HS01GTFPBHB033 datasheet, S28HS01GTFPBHB033 pinout, S28HS01GTFPBHB033 application, or S28HS01GTFPBHB033 equivalent, key selection criteria include octal DDR throughput, ASIL-B functional safety certification, 25-year data retention, 2.56M program-erase cycles, and 8×8 mm 24-ball BGA packaging compatible with automotive AEC-Q100 Grade 1 (−40 °C to +125 °C).

Technical Context

This device integrates dual-controller architecture: Host Interface Controller (HIC) handles SPI/OPI protocol timing and signal management, while Embedded Algorithm Controller (EAC) executes autonomous erase/program algorithms without host intervention. It supports JEDEC JESD251-compliant xSPI with both SDR (200 MHz) and DDR (200 MHz) octal modes, plus legacy x1 SPI.

The memory array uses 45-nm MirrorBit® technology storing two bits per cell, enabling uniform 256 KB sectors or hybrid configurations with thirty-two 4 KB sectors. Built-in Data Integrity CRC, Interface CRC, SafeBoot, and sector-level erase status reporting provide deterministic failure detection and recovery in safety-critical systems.

This part belongs to the Semper® Flash with Octal Interface product line, designed specifically to replace parallel NOR and legacy SPI flash in safety-critical systems demanding high bandwidth, functional safety certification, and configurable endurance/retention trade-offs.

FAQ

What is the purpose of the DS (Data Strobe) pin on S28HS01GTFPBHB033?

The DS pin is a synchronous output that toggles in phase with read data on DQ[7:0] during active CS# LOW periods. It enables precise timing capture of high-speed octal DDR reads (up to 400 MBps) by providing a dedicated strobe signal-eliminating setup/hold margin concerns that would arise using CK alone for data sampling in the host controller.

Does S28HS01GTFPBHB033 support execute-in-place (XIP) operation?

Yes, the device supports XIP mode via octal DDR interface, allowing the host MCU to fetch instructions directly from flash without copying to RAM. This is enabled by linear burst read capability and deterministic latency (23 cycles for DDR read), making it suitable for real-time automotive boot and safety firmware execution.

How does the EnduraFlex™ architecture function in practice?

EnduraFlex™ allows the host to define memory partitions via configuration registers: one region optimized for ≥1 million program-erase cycles (e.g., for runtime parameters), another for 25-year data retention (e.g., calibration constants). These settings persist across power cycles and are enforced by the Embedded Algorithm Controller during all program/erase operations.

Is RESET# required for normal operation of S28HS01GTFPBHB033?

No, RESET# is optional. The device performs automatic initialization on power-up (POR) and can be controlled entirely via CS# signaling per JEDEC standard. RESET# is provided for asynchronous hardware reset-useful for recovering from undefined states-but is not needed for routine boot or operation if the host manages CS# correctly.
