Infineon Technologies S28HS01GTFPBHI030

Overview

S28HS01GTFPBHI030 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/retention partitions-used in automotive ADAS boot code storage and industrial controller firmware.

For engineers reviewing the S28HS01GTFPBHI030 datasheet, S28HS01GTFPBHI030 pinout, S28HS01GTFPBHI030 application, or S28HS01GTFPBHI030 equivalent, key selection criteria include octal DDR timing compliance, 2.56M program-erase cycles, SFDP support, SafeBoot initialization reporting, and AEC-Q100 Grade 2 (−40 °C to +105 °C) qualification.

Technical Context

This device implements Cypress's 45-nm MirrorBit® technology with two bits per cell and supports both uniform (all 256 KB sectors) and hybrid sector architectures (32 × 4 KB + remainder 256 KB). Its Host Interface Controller (HIC) and Embedded Algorithm Controller (EAC) operate in parallel to manage JEDEC JESD251-compliant xSPI transactions and autonomous embedded algorithms for erase/program.

The octal interface operates in SDR (200 MHz, 200 MBps) or DDR (200 MHz, 400 MBps) modes with mandatory Data Strobe (DS) for timing-critical read capture. Built-in SECDED ECC corrects single-bit errors and detects double-bit errors in the main array, while Interface CRC and Data Integrity CRC protect communication and stored data respectively.

FAQ

Does S28HS01GTFPBHI030 support both SDR and DDR octal read modes?

Yes, it supports both SDR (200 MHz, 200 MBps) and DDR (200 MHz, 400 MBps) octal read modes per JEDEC JESD251. The DS signal is active in both modes to synchronize read data capture. Mode selection is configured via status register bits and requires no hardware change.

What is the purpose of the DNU pins in the 24-ball BGA package?

DNU (Do Not Use) pins are reserved, unconnected die pads with no internal bonding. They must remain floating and unconnected on PCB layout to prevent electrical interference or mechanical stress. Cypress explicitly warns against ultrasonic cleaning or exposure above 150 °C due to BGA package sensitivity.

How does SafeBoot detect and recover from configuration corruption?

SafeBoot validates boot configuration registers and SFDP parameter tables at power-on. If corruption is detected, it triggers a fallback to factory-default settings and reports the event via INT# assertion and status register flags, allowing host firmware to initiate recovery without manual intervention.

Can the 4 KB sectors be programmed independently of the 256 KB sectors?

Yes, the hybrid sector architecture allows independent programming and erasing of 4 KB and 256 KB sectors. Each 4 KB sector has its own protection register and erase counter. Programming uses the same 256/512-byte page buffer regardless of sector size, with verified write-through behavior per JEDEC spec.
