Infineon Technologies S28HS01GTFPBHV030

Overview

S28HS01GTFPBHV030 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.

For engineers reviewing the S28HS01GTFPBHV030 datasheet, S28HS01GTFPBHV030 pinout, S28HS01GTFPBHV030 application, or S28HS01GTFPBHV030 equivalent, key selection criteria include octal DDR timing performance, functional safety certification status, sector architecture flexibility (hybrid 4 KB/256 KB), built-in SECDED ECC, and automotive-grade temperature support (−40 °C to +105 °C).

Technical Context

This device implements Cypress's 45-nm MirrorBit® technology with two bits per cell and dual-controller architecture: Host Interface Controller (HIC) manages SPI/OPI transactions and timing, while Embedded Algorithm Controller (EAC) executes autonomous program/erase algorithms. It supports JEDEC JESD251-compliant xSPI protocols including SDR and DDR modes on both octal (8D-8D-8D) and legacy SPI (1S-1S-1S) interfaces.

The memory array uses uniform or hybrid sector architecture (32 × 4 KB sectors + remaining 256 KB sectors), with programmable page buffer (256/512 bytes), integrated Data Strobe (DS) for high-speed read capture, and SafeBoot for initialization failure detection and configuration recovery.

FAQ

What is the maximum DDR read bandwidth supported by S28HS01GTFPBHV030?

The device achieves 400 MBps DDR read bandwidth using the octal interface at 200 MHz clock frequency (8D-8D-8D DDR mode). This is measured under HS-T conditions (1.7–2.0 V) and confirmed in the Performance Summary table on page 2 of Document 002-23881 Rev. *A. The bandwidth assumes continuous linear burst reads with DS synchronization enabled.

Does S28HS01GTFPBHV030 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). These are selectable via configuration registers and documented in the Device Overview section on page 2 of the datasheet.

How does SafeBoot enhance system reliability during power-on?

SafeBoot performs internal validation of configuration registers and memory initialization sequence upon power-up. If corruption or failure is detected, it reports the error via status registers and offers recovery paths - such as loading default configuration or entering safe mode - without requiring host-level intervention or external watchdog supervision.

Is RESET# pin mandatory for normal operation of S28HS01GTFPBHV030?

No - RESET# is optional and features an internal weak pull-up. When left unconnected, the pin defaults to HIGH and the device relies on CS#-based power-on reset behavior. However, asserting RESET# LOW provides deterministic hardware-initiated reset independent of CS# timing, which is recommended for systems requiring guaranteed initialization state alignment.
