Infineon Technologies S28HL01GTFPBHV030

Overview

S28HL01GTFPBHV030 from Cypress Semiconductor is a 1-Gb (128-MB) high-reliability NOR flash memory with Octal xSPI interface, operating at 3.0 V (HL-T), rated for automotive AEC-Q100 Grade 2 (−40 °C to +105 °C), supporting DDR read up to 400 MBps and featuring ISO 26262 ASIL-B compliance and EnduraFlex™ architecture for configurable endurance/retention partitions.

For engineers reviewing the S28HL01GTFPBHV030 datasheet, S28HL01GTFPBHV030 pinout, S28HL01GTFPBHV030 application, or S28HL01GTFPBHV030 equivalent, key selection considerations include octal DDR timing performance, sector protection granularity, SafeBoot initialization reporting, ECC SECDED capability, and automotive-grade thermal and functional safety validation.

Technical Context

This device implements Cypress's 45-nm MirrorBit® technology with two bits per cell and supports hybrid sector architecture-32 × 4 KB sectors (top/bottom or split) plus uniform 256 KB sectors-enabling flexible firmware partitioning. It integrates dual-controller logic: Host Interface Controller (HIC) for protocol handling and Embedded Algorithm Controller (EAC) for autonomous program/erase execution.

The octal interface complies with JEDEC JESD251, offering both SDR (166 MHz, 166 MBps) and DDR (166 MHz, 332 MBps) modes with Data Strobe (DS) for precise read capture. Built-in Interface CRC and Data Integrity CRC detect communication and array errors, while SafeBoot validates configuration integrity during power-on initialization.

FAQ

What is the purpose of the DS (Data Strobe) pin on S28HL01GTFPBHV030?

The DS pin is a synchronous output that toggles in phase with read data on DQ[7:0] during octal interface reads. It provides precise timing reference for the host controller to sample data reliably at high frequencies (up to 166 MHz DDR), eliminating setup/hold margin concerns inherent in source-synchronous clocking schemes. DS remains active only while CS# is asserted and ceases when CS# goes high.

Does S28HL01GTFPBHV030 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 at top or bottom), and hybrid configuration 2 (32 × 4 KB sectors split evenly between top and bottom). The configuration is fixed at factory mask time and cannot be changed in-system; ordering codes specify the intended layout (e.g., FP = hybrid configuration 1).

How does SafeBoot enhance reliability during power-on initialization?

SafeBoot performs integrity checks on critical configuration registers and boot parameters immediately after power-up. If corruption is detected - such as from incomplete write or voltage droop - it flags the error via status registers and optionally enters a recovery mode allowing host intervention before executing potentially invalid code. This prevents silent boot failures in safety-critical automotive systems.

Can S28HL01GTFPBHV030 be used with legacy SPI controllers?

Yes - it supports standard x1 SPI (1S-1S-1S) mode using only DQ0 (SI) and DQ1 (SO) pins, compliant with JEDEC JESD251. In this mode, maximum SDR read speed is 21 MBps (166 MHz clock), and all octal-specific features (DS, DDR, 8D-8D-8D) are disabled. Command sets remain compatible, enabling migration from legacy SPI NOR without firmware rewrite.
