Infineon Technologies S28HL512TFPBHI013

Overview

S28HL512TFPBHI013 from Cypress Semiconductor (now Infineon) is a 512-Mb (64-MB), 3.0-V supply, industrial-grade (−40 °C to +85 °C), Semper® Flash NOR memory with Octal xSPI interface, 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 S28HL512TFPBHI013 datasheet, S28HL512TFPBHI013 pinout, S28HL512TFPBHI013 application, or S28HL512TFPBHI013 equivalent, key selection criteria include octal DDR timing margin, EnduraFlex® partitioning for mixed endurance/retention requirements, SafeBoot initialization reporting, and 24-ball 6×8 mm BGA footprint compatibility with high-density automotive PCB layouts.

Technical Context

This device implements Cypress's 45-nm MirrorBit® technology with two bits per cell 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 internal erase/program execution.

The octal interface complies fully with JEDEC JESD251, supporting 8S-8S-8S and 8D-8D-8D protocols with Data Strobe (DS) for timing-critical read capture. Built-in SECDED ECC corrects single-bit errors and detects double-bit errors across the entire memory array, while Interface CRC validates all command/address/data transfers.

Equivalent & Alternatives

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

Compared with S28HL512TFPBHI013, the 023 variant offers identical functionality in reel format for volume manufacturing, while the Macronix part trades ASIL-B compliance for higher density and lower voltage - making it unsuitable for safety-critical boot storage but viable for cost-sensitive consumer-tier applications.

S28HL512TFPBHI013 is available at Aetrix Electronics and suitable for automotive ADAS camera modules, engine control units, and infotainment head units requiring stable component supply, long-term lifecycle assurance, and AEC-Q100 Grade 3 qualification.

Supply support for S28HL512TFPBHI013 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Infineon Technologies acquired Cypress Semiconductor in 2020 and now manufactures the Semper Flash family, delivering high-reliability memory solutions for automotive, industrial, and communications markets.

The Semper Flash product line was designed specifically for functional safety–critical applications, combining high-speed octal interface performance with ISO 26262–aligned reliability features including SafeBoot, EnduraFlex®, and embedded SECDED ECC.

FAQ

What is the purpose of the DS (Data Strobe) pin on S28HL512TFPBHI013?

The DS pin outputs a source-synchronous strobe synchronized with DQ[7:0] read data edges. It enables reliable data capture at high speeds (up to 200 MHz DDR) by eliminating clock-to-data skew, especially critical in automotive PCBs with length-mismatched traces. DS toggles only during active CS# read transactions and remains inactive in standby or write modes.

Does S28HL512TFPBHI013 support both SDR and DDR modes on its octal interface?

Yes - the device supports both SDR (up to 200 MBps at 200 MHz) and DDR (up to 400 MBps at 200 MHz) on the octal interface. Mode selection is controlled via configuration registers programmed during initialization; the default power-on mode is SDR, and DDR must be explicitly enabled using the Read Status Register command per JEDEC JESD251.

How does the EnduraFlex® architecture work in practice for system design?

EnduraFlex® allows the host to define up to four non-overlapping memory partitions with independent endurance (1M+ cycles) and retention (25-year) profiles. Partition boundaries and attributes are stored in dedicated configuration registers and persist across power cycles. This lets designers allocate high-endurance space for OTA update buffers while reserving long-retention zones for immutable boot code - all within a single die.

Is the RESET# pin required for normal operation of S28HL512TFPBHI013?

No - RESET# is optional and internally weak-pulled HIGH. The device performs automatic power-on reset (POR) and SafeBoot initialization without external reset assertion. However, connecting RESET# to a system supervisor IC enables coordinated reset sequencing across multiple devices and recovers from lockup conditions that POR alone cannot resolve, such as stuck internal state machines.
