Infineon Technologies S28HL512TFPBHV013

Overview

S28HL512TFPBHV013 from Cypress Semiconductor (now Infineon) is a 512-Mb (64-MB), 3.0-V supply, Octal-interface NOR flash memory with JEDEC JESD251 compliance, 400 MBps DDR read throughput, and ISO 26262 ASIL-B compliance for automotive safety-critical boot code storage in ADAS ECUs.

For engineers reviewing the S28HL512TFPBHV013 datasheet, S28HL512TFPBHV013 pinout, S28HL512TFPBHV013 application, or S28HL512TFPBHV013 equivalent, key selection criteria include octal DDR timing margin, EnduraFlex partitioning for mixed endurance/retention requirements, 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 dual-bit-per-cell storage 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 decouple host command handling from embedded erase/program execution.

The octal interface operates in SDR (up to 166 MHz / 166 MBps) or DDR (up to 166 MHz / 332 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 across the main array, while Interface CRC validates all command/address/data transfers.

FAQ

What is the purpose of the DS (Data Strobe) pin on S28HL512TFPBHV013?

The DS pin is a source-synchronous output that toggles in phase with read data on DQ[7:0] during octal interface operations. It enables precise data capture at high frequencies (up to 166 MHz DDR) by providing a dedicated timing reference, eliminating setup/hold margin constraints imposed by clock-to-out skew in conventional interfaces.

Does S28HL512TFPBHV013 support legacy SPI mode in addition to octal interface?

Yes - it supports x1 SPI (SI/SO on DQ0/DQ1) as a fallback interface per JEDEC JESD251. This mode operates at up to 166 MHz SDR (20.75 MBps), allowing compatibility with legacy boot controllers while retaining access to SFDP, ECC, and SafeBoot features without requiring octal-capable hardware.

How does EnduraFlex™ Architecture affect memory partitioning in practice?

EnduraFlex allows the host to define nonvolatile partitions with distinct endurance/retention profiles using dedicated configuration commands. For example, 32 × 4 KB sectors can be assigned to high-endurance mode (1.28M cycles) for logging buffers, while the remaining 256 KB sectors remain in long-retention mode (25 years) for immutable firmware images - all within the same physical die.

Is RESET# pin required for normal operation of S28HL512TFPBHV013?

No - RESET# is optional and internally pulled up. The device performs full initialization on power-on reset (POR) and remains functional with CS# control alone. RESET# is provided for synchronous system-level reset events; when asserted, it forces immediate return to array-read state and places DQ/DS in high-impedance, independent of CS# level.
