Infineon Technologies S25HL02GTDPBHB053

Overview

S25HL02GTDPBHB053 from Infineon is a 2-Gb Dual Die Package (DDP) SEMPER™ NOR flash memory with Quad SPI interface, 1.8 V/3.0 V dual supply support, ISO 26262 ASIL-B compliant safety architecture, and 256 KB uniform or hybrid sector configuration. It delivers up to 102 MBps DDR read throughput, supports 2.56M program-erase cycles in main array, and operates across –40°C to +105°C for industrial-plus applications including automotive boot code storage.

For engineers reviewing the S25HL02GTDPBHB053 datasheet, S25HL02GTDPBHB053 pinout, S25HL02GTDPBHB053 application, or S25HL02GTDPBHB053 equivalent, key selection criteria include Quad SPI DDR timing compliance, ASIL-B functional safety certification, EnduraFlex™ endurance partitioning, 24-ball BGA package compatibility, and OTP secure silicon integration for firmware authentication.

Technical Context

This device implements Infineon's 45-nm MIRRORBIT™ technology with two bits per cell and integrates an embedded microcontroller for command execution, ECC (SECDED), CRC-based data integrity checking, and SafeBoot initialization monitoring. Its EnduraFlex™ architecture enables independent endurance and retention tuning across memory partitions.

The 24-ball BGA package houses two stacked 1-Gb dies sharing common control signals (CS#, CK, DQ[3:0]), supporting 1S-1S-4S, 1S-4S-4S, 1S-4D-4D, 4S-4S-4S, and 4S-4D-4D protocols with configurable 256/512-byte page buffers and SFDP-defined parameter discovery.

FAQ

Is S25HL02GTDPBHB053 pin-compatible with earlier Cypress S25HL series devices?

Yes - this part retains identical 24-ball BGA pinout, electrical signaling, and command set as legacy Cypress S25HL devices. The transition to Infineon branding does not affect mechanical or functional compatibility, and existing PCB layouts require no modification for drop-in replacement.

What is the role of the DQ3/RESET# pin in Quad SPI mode?

In Quad SPI mode, DQ3 functions exclusively as a bidirectional data line (DQ3). The RESET# functionality is disabled when Quad SPI is active. Hardware reset must be performed using CS# deassertion followed by power cycle or via dedicated RESET# pin if configured separately in non-Quad mode.

Does S25HL02GTDPBHB053 support execute-in-place (XIP) operation?

Yes - the device supports XIP via Quad SPI DDR protocol with linear burst reads, enabling direct code execution from flash without copying to RAM. Latency is minimized by 102 MBps DDR throughput and configurable wrap/linear burst modes aligned to cache line boundaries.

How is the OTP Secure Silicon region accessed and protected?

The 1024-byte OTP region is accessed via standard SPI commands after unlocking with specific vendor-specific register writes. Once programmed, bits cannot be erased; protection is enforced by hardware lock bits that disable further writes upon first programming, ensuring cryptographic key immutability.
