Infineon Technologies S28HS02GTFPBHB053

Overview

S28HS02GTFPBHB053 from Infineon is a 2 Gb (256 MB) Octal SPI NOR Flash memory with dual-die package (DDP), 1.8 V core/I/O supply, industrial-plus temperature grade (–40 °C to +105 °C), and JEDEC JESD251-compliant xSPI interface supporting up to 332 MBps DDR read throughput. It integrates MIRRORBIT™ 45-nm technology, SECDED ECC, SafeBoot, and ASIL-B functional safety compliance for automotive and industrial embedded storage.

For engineers reviewing the S28HS02GTFPBHB053 datasheet, S28HS02GTFPBHB053 pinout, S28HS02GTFPBHB053 application, or S28HS02GTFPBHB053 equivalent, key selection criteria include octal DDR timing performance, 256 KB/4 KB hybrid sector architecture, 2.56M program-erase cycles, SFDP support, and AEC-Q100 Grade 2 qualification.

Technical Context

This device implements a dual-die MCP architecture with shared control signals across two 1 Gb MIRRORBIT™ arrays, enabling uniform address mapping and concurrent die access under host arbitration. Its HIC/EAC dual-controller architecture separates host interface timing management from embedded erase/program algorithms, ensuring deterministic latency for safety-critical boot code retrieval.

The octal interface supports both SDR (166 MHz, 166 MBps) and DDR (166 MHz, 332 MBps) modes with data strobe (DS) for precise read capture, while legacy SPI mode provides backward compatibility at up to 21 MBps. Sector protection includes legacy block lock and per-sector advanced lock, enforced via nonvolatile configuration registers.

Key Specifications

Pinout & Package

24-ball BGA package, 8 mm × 8 mm, 0.8 mm pitch, RoHS-compliant. Pinout optimized for high-speed octal signaling with dedicated DS, separate VCCQ/VSSQ for I/O domain isolation, and weak-pullup RESET#.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-reliability octal NOR flash applications.

Compared with S28HS02GTFPBHB053, the Cypress alternative omits safety-critical firmware recovery mechanisms, while the Macronix part lacks thermal and qualification coverage for automotive-grade deployment-making the Infineon device uniquely suited for ASIL-B systems requiring guaranteed boot integrity at 105 °C.

FAQ

What is the maximum clock frequency supported in DDR octal mode?

The S28HS02GTFPBHB053 supports DDR octal read operations at up to 166 MHz clock frequency, achieving 332 MBps effective throughput. This is validated across the full industrial-plus temperature range (–40 °C to +105 °C) and specified in the official Infineon datasheet revision ** (002-34695). The device uses source-synchronous DS signaling to maintain timing margin at this rate.

Does this part include hardware reset functionality independent of chip select?

Yes. The S28HS02GTFPBHB053 includes a dedicated RESET# pin with internal weak pull-up, allowing asynchronous hardware reset regardless of CS# state. When asserted LOW, it forces self-initialization and returns the device to array read state, placing DS and DQ[7:0] into high-impedance-enabling safe reset during power sequencing or fault recovery without relying on CS# timing.

How is sector protection implemented, and can it be configured per sector?

Sector protection uses two complementary methods: legacy block protection (BP bits in status register) and advanced sector protection (ASP) enabled via nonvolatile configuration registers. ASP allows individual 4 KB or 256 KB sectors to be locked/unlocked independently using write commands, providing granular firmware partitioning-critical for secure OTA updates and bootloader isolation.

Is SFDP support mandatory for host initialization, and what parameters does it expose?

Yes. SFDP (Serial Flash Discoverable Parameters) is mandatory and implemented per JEDEC JESD251. It exposes standardized tables including basic flash parameters (density, erase types), xSPI capabilities (SDR/DDR support, DS polarity), timing requirements (tCH/tCL, tDSH), and safety features (SafeBoot presence, ECC type). Hosts use this to auto-configure drivers without hardcoded assumptions.
