Infineon Technologies S28HS01GTFPBHV033

Overview

S28HS01GTFPBHV033 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), supporting up to 400 MBps DDR read throughput and ISO 26262 ASIL-B compliance for automotive safety-critical boot code storage in ADAS ECUs.

For engineers reviewing the S28HS01GTFPBHV033 datasheet, S28HS01GTFPBHV033 pinout, S28HS01GTFPBHV033 application, or S28HS01GTFPBHV033 equivalent, key selection criteria include octal DDR timing performance, EnduraFlex™ partitioned endurance (2.56M P/E cycles main array), SECDED ECC, SafeBoot initialization reporting, and AEC-Q100 Grade 2 (−40 °C to +105 °C) qualification.

Technical Context

This device implements Cypress's 45-nm MirrorBit® architecture with dual-bit-per-cell storage and supports both JEDEC JESD251-compliant Octal Peripheral Interface (8D-8D-8D DDR/SDR) and legacy SPI (1S-1S-1S). It features two independent controller blocks: Host Interface Controller (HIC) for transaction management and Embedded Algorithm Controller (EAC) for autonomous program/erase execution.

The memory array offers hybrid sector architecture-thirty-two 4 KB sectors (top/bottom or split) plus uniform 256 KB sectors-and integrates Data Strobe (DS) for precise DDR read capture, Interface CRC for command/address integrity, and Data Integrity CRC for array-level error detection.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S28HS01GTFPBHV033 supports a maximum clock frequency of 200 MHz in DDR mode, achieving 400 MBps effective read throughput. This is specified under HS-T (1.8-V) operation with CK duty cycle between 45% and 55%, and is validated across the full −40 °C to +105 °C temperature range per AEC-Q100 Grade 2 requirements.

Does this device support true XIP (eXecute-In-Place) from octal interface?

Yes - the device supports deterministic XIP execution via octal DDR interface with wrapped burst reads, enabling CPU cores to fetch instructions directly from flash without intermediate RAM buffering. Latency is guaranteed ≤100 ns for first-word access, and the DS signal ensures reliable data capture at 400 MBps without external timing compensation.

How is the 4 KB sector erase functionality implemented in hybrid sector architecture?

The device provides thirty-two dedicated 4 KB sectors that can be configured either at top/bottom (Configuration 1) or split equally (Configuration 2). Erase of these sectors uses the same command sequence as 256 KB sectors but completes in ~95 ms typical. Each 4 KB sector maintains independent erase status reporting and cycle counting via Sector Erase Counter registers.

Is the RESET# pin required for automotive applications?

No - RESET# is optional and internally weak-pulled high; it may be left unconnected. However, in AEC-Q100 Grade 2 systems, using RESET# improves robustness against brown-out conditions by forcing deterministic reinitialization. The device also supports hardware reset via CS# assertion per JEDEC standard, providing redundancy without additional pins.
