Infineon Technologies S28HL01GTFPBHV033

Overview

S28HL01GTFPBHV033 from Cypress Semiconductor (now Infineon) is a 1-Gb (128-MB), 3.0-V Semper® Flash NOR memory with Octal xSPI interface, ISO 26262 ASIL-B compliant functional safety architecture, 256 KB uniform sector erase, and 2.7–3.6 V supply range. It delivers up to 332 MBps DDR read throughput at 166 MHz clock, supports Data Strobe (DS) for high-speed read capture, and features EnduraFlex™ partitioning for configurable endurance/retention trade-offs in automotive ADAS firmware storage.

For engineers reviewing the S28HL01GTFPBHV033 datasheet, S28HL01GTFPBHV033 pinout, S28HL01GTFPBHV033 application, or S28HL01GTFPBHV033 equivalent, key selection criteria include octal DDR timing compliance, AEC-Q100 Grade 2 (−40 °C to +105 °C) qualification, 2.56M program-erase cycles in main array, SFDP v1.6 support, and hardware reset via dedicated RESET# pin.

Technical Context

This device implements Cypress's 45-nm MirrorBit® technology with two bits per cell and dual-controller architecture: Host Interface Controller (HIC) handles SPI/OPI protocol parsing and data transfer, while Embedded Algorithm Controller (EAC) autonomously executes embedded programming/erase algorithms without host intervention. It supports both JEDEC JESD251-compliant xSPI (SDR/DDR) and legacy 1S-1S-1S SPI modes.

The memory array uses hybrid or uniform sector architecture with configurable 4 KB and 256 KB sectors; page programming buffer is selectable between 256 B and 512 B. Built-in SECDED ECC corrects single-bit errors and detects double-bit errors on read, while Interface CRC and Data Integrity CRC provide end-to-end error detection across bus and array.

Equivalent & Alternatives

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

Compared with S28HL01GTFPBHV033, the 020 variant offers identical reliability but reduced boot flexibility, while the Macronix part trades ASIL-B compliance and endurance for lower cost and 1.8 V operation-making it unsuitable for AEC-Q100 Grade 2 automotive use.

Manufacturer

Infineon Technologies acquired Cypress Semiconductor in 2020 and now develops, manufactures, and supports the Semper Flash family as part of its automotive and industrial memory portfolio.

The Semper Flash product line was designed specifically for functional safety–critical applications in automotive ECUs, industrial controllers, and medical devices-delivering certified reliability, configurable endurance/retention, and high-speed octal interface performance.

FAQ

What is the difference between S28HL01GTFPBHV033 and S28HL01GTFPBHV020?

The "033" suffix indicates x1 default boot configuration in an 8×8 mm 24-ball BGA package, while "020" denotes x1 default boot in a 6×8 mm package. Both share identical electrical specs, temperature grade (AEC-Q100 Grade 2), and functional safety features-but only the 033 variant supports the larger footprint required for thermal dissipation in high-power ADAS modules.

Does S28HL01GTFPBHV033 support both SDR and DDR octal modes?

Yes-it fully supports JEDEC JESD251-compliant octal SDR (up to 166 MBps) and DDR (up to 332 MBps) modes. The interface mode is selected via configuration register bits; no hardware changes are needed. DDR mode requires DS signal routing and proper PCB timing closure for 166 MHz differential clock paths.

How does SafeBoot enhance system reliability during power-on?

SafeBoot performs three checks at power-up: validates internal configuration registers, verifies boot sector integrity using stored CRC, and confirms successful initialization of ECC and interface logic. If any check fails, it asserts INT# and enters safe recovery mode-allowing host firmware to initiate fallback boot or diagnostics before system lockup occurs.

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

Yes-the hybrid sector architecture allows 32 × 4 KB sectors to be placed either at top/bottom (Configuration 1) or split evenly (Configuration 2), with all other sectors remaining 256 KB. This is configured via nonvolatile registers and enables separate update domains for volatile parameters (e.g., calibration) and immutable firmware (e.g., boot loader).
