Infineon Technologies S28HL512TFPBHB013

Overview

S28HL512TFPBHB013 from Cypress Semiconductor is a 512-Mb (64-MB) 3.0-V Semper® Flash NOR memory with Octal xSPI interface, ISO 26262 ASIL-B compliant safety architecture, 24-ball BGA (6 × 8 mm) package, and EnduraFlex™ partitioning for high-endurance/long-retention use in automotive boot code storage.

For engineers reviewing the S28HL512TFPBHB013 datasheet, S28HL512TFPBHB013 pinout, S28HL512TFPBHB013 application, or S28HL512TFPBHB013 equivalent, key selection criteria include octal DDR read throughput (332 MBps), 1.28M program-erase cycles, ASIL-B functional safety certification, and automotive 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 JEDEC JESD251-compliant Octal Peripheral Interface (8S-8S-8S / 8D-8D-8D) and legacy SPI (1S-1S-1S). It features two independent controller blocks: Host Interface Controller (HIC) for signal management and Embedded Algorithm Controller (EAC) for autonomous program/erase execution.

The architecture includes hardware-level error resilience: SECDED ECC on memory array, interface CRC, Data Integrity CRC, SafeBoot initialization validation, and sector erase status reporting. EnduraFlex™ enables runtime partitioning of memory into high-endurance (≥1.28M cycles) and long-retention (25-year) regions.

FAQ

What is the purpose of the DS (Data Strobe) pin on S28HL512TFPBHB013?

The DS pin outputs a synchronous toggle signal aligned with valid DQ[7:0] read data edges during octal interface operations. It eliminates timing margin uncertainty in high-speed DDR reads (up to 200 MHz), allowing host controllers to latch data reliably without complex deskew circuitry or tight PCB trace length matching.

Does S28HL512TFPBHB013 support both SDR and DDR modes on its octal interface?

Yes - it supports both SDR (up to 166 MHz, 166 MBps) and DDR (up to 166 MHz clock, 332 MBps) on the octal interface. Mode selection is controlled via configuration registers defined in the SFDP table; no external pin strapping is required. The device automatically adapts timing based on detected command sequence.

How does EnduraFlex™ architecture improve system-level reliability?

EnduraFlex™ allows the host to define memory partitions with distinct endurance (≥1.28M cycles) and retention (25 years) profiles. This enables separation of frequently updated data (e.g., OTA logs) from static firmware, preventing wear-out of critical boot code and extending total device lifetime beyond 15 years in automotive applications.

Is the RESET# pin mandatory for normal operation of S28HL512TFPBHB013?

No - RESET# is optional and internally weak-pulled high. If left unconnected, the device relies on CS#-driven power-on reset and SafeBoot validation. However, using RESET# enables deterministic hard reset during fault recovery, especially when CS# cannot be asserted (e.g., during bus contention or host lockup).
