Infineon Technologies S28HL01GTFPBHM030

Overview

S28HL01GTFPBHM030 from Cypress Semiconductor is a 1-Gb (128-MB), 3.0-V Semper® Flash NOR memory with Octal xSPI interface, ISO 26262 ASIL-B compliant safety architecture, 256 KB/4 KB hybrid sector configuration, and 2.7–3.6 V supply range. It delivers up to 332 MBps DDR read throughput at 166 MHz clock, supports EnduraFlex™ partitioning for high-endurance or long-retention use, and targets automotive boot code storage in ADAS ECUs.

For engineers reviewing the S28HL01GTFPBHM030 datasheet, S28HL01GTFPBHM030 pinout, S28HL01GTFPBHM030 application, or S28HL01GTFPBHM030 equivalent, key selection criteria include ASIL-B functional safety certification, octal DDR read performance, 24-ball 8×8 mm BGA package compatibility, and hybrid sector protection for firmware update resilience.

Technical Context

This device implements Cypress's 45-nm MirrorBit® technology with dual-bit-per-cell storage and integrates two parallel controllers: Host Interface Controller (HIC) for SPI/OPI transaction handling and Embedded Algorithm Controller (EAC) for autonomous program/erase execution. It supports JEDEC JESD251-compliant xSPI protocols including SDR and DDR modes over DQ[7:0] with Data Strobe (DS) synchronization.

The architecture includes dedicated hardware blocks for SECDED ECC (single-bit correction, double-bit detection), interface CRC, SafeBoot initialization validation, and Sector Erase Status reporting. Its EnduraFlex™ partitioning enables runtime allocation of endurance-critical sectors (≥2.56M P/E cycles) versus retention-critical sectors (25-year data retention).

FAQ

What is the maximum DDR read bandwidth supported by S28HL01GTFPBHM030?

The device achieves 332 MBps DDR read bandwidth using the octal interface at 166 MHz clock frequency (8D-8D-8D DDR mode). This is measured under HL-T (3.0 V) conditions with DS-synchronized data capture and accounts for protocol overhead. The bandwidth scales linearly with clock rate up to the rated 166 MHz limit.

Does S28HL01GTFPBHM030 require external hardware for ECC correction?

No. The device integrates a hardware SECDED (Single Error Correction, Double Error Detection) ECC engine that operates transparently during all read operations. It automatically corrects single-bit errors and flags double-bit errors without host intervention or additional components, meeting ASIL-B requirements for fault containment.

How does the hybrid sector architecture benefit firmware update implementations?

The hybrid architecture provides thirty-two 4 KB sectors (top/bottom configurable) alongside 256 KB sectors, enabling atomic patching of bootloader code in small sectors while storing bulk application firmware in larger sectors. This eliminates partial-write risks during power loss and supports secure dual-bank OTA updates without external RAM buffering.

Is RESET# pin mandatory for automotive Grade 1 operation?

No. RESET# is optional but recommended for deterministic initialization recovery. The device supports hardware reset via CS# signaling per JEDEC, but the dedicated RESET# pin provides asynchronous reset capability independent of chip select state-critical for fail-safe restart in powertrain modules where CS# may be held active during fault conditions.
