Infineon Technologies S25HL02GTDPBHV050

Overview

S25HL02GTDPBHV050 from Infineon is a 2-Gb Dual Die Package (DDP) SEMPER™ NOR Flash memory with Quad SPI interface, 1.8 V supply (HS-T grade), industrial temperature range (–40°C to +85°C), and ISO 26262 ASIL-B compliant functional safety architecture. It features 256 KB uniform sectors or hybrid 4 KB/256 KB sector configuration, 256/512-byte page programming buffer, and built-in SECDED ECC for memory array data integrity.

For engineers reviewing the S25HL02GTDPBHV050 datasheet, S25HL02GTDPBHV050 pinout, S25HL02GTDPBHV050 application, or S25HL02GTDPBHV050 equivalent, key selection criteria include Quad SPI DDR read throughput (102 MBps), 2.56M program-erase cycles in main array, 25-year data retention, hardware reset via CS#/RESET#/DQ3, and AEC-Q100 Grade 3 qualification for automotive boot code storage.

Technical Context

This device implements Infineon's 45-nm MIRRORBIT™ technology storing two bits per cell in a monolithic multi-chip package with two stacked 1-Gb dies sharing common control signals. Its EnduraFlex™ architecture partitions memory into high-endurance (4 KB sectors, 300k cycles) and long-retention (256 KB sectors, 2.56M cycles) regions.

The Quad SPI interface supports five protocols (1S-1S-4S, 1S-4S-4S, 1S-4D-4D, 4S-4S-4S, 4S-4D-4D) with SDR up to 166 MHz (83 MBps) and DDR up to 102 MHz (102 MBps). SafeBoot monitors initialization and configuration corruption, while CRC and SECDED ECC ensure end-to-end data integrity during read/write/erase operations.

Key Specifications

Pinout & Package

24-ball BGA package (8 mm × 8 mm, 0.8 mm pitch), RoHS-compliant, with thermal pad option (PBHV suffix indicates Pb-free, HV = high-reliability variant).

Key Features

Applications

Equivalent & Alternatives

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

Compared with S25HL02GTDPBHV050, the Cypress-branded version offers identical performance and qualification, while the Macronix part lacks ASIL-B compliance, 2-Gb density, and EnduraFlex endurance tuning - making it unsuitable for automotive or medical safety-critical boot storage.

FAQ

What is the maximum Quad SPI DDR read bandwidth supported by S25HL02GTDPBHV050?

The device achieves 102 MBps read bandwidth using Quad SPI DDR mode at 102 MHz clock frequency, confirmed in Table 1 of the official Infineon datasheet (002-28767 Rev. *A). This requires host controller support for DDR protocol and proper PCB layout for signal integrity at 204 Mbps per DQ line.

Does S25HL02GTDPBHV050 support hardware reset independent of chip select?

Yes - it supports three hardware reset methods: CS# deassertion followed by timing sequence, dedicated RESET# pin (ball E2), or DQ3 configured as RESET# when Quad SPI is disabled. All methods trigger SafeBoot initialization and return the device to array read state with DQ lines in high-impedance.

How does the EnduraFlex™ architecture improve reliability in field-deployed systems?

EnduraFlex™ separates the memory array into independently configurable partitions: 4 KB sectors (300k cycles) for frequently updated NV parameters and 256 KB sectors (2.56M cycles) for firmware. This prevents premature wear-out of boot code regions during repeated OTA updates, extending usable lifetime beyond 15 years in automotive applications.

Is the 1024-byte OTP Secure Silicon region one-time programmable or reprogrammable?

The 1024-byte OTP Secure Silicon array is strictly one-time programmable - once written, bits cannot be erased or rewritten. It is used for storing immutable cryptographic keys, secure boot certificates, and device-unique identifiers, with write protection enforced by hardware fuses and register locks per Infineon's security documentation.
