Infineon Technologies S25HL02GTDPBHM053

Overview

S25HL02GTDPBHM053 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 functional safety architecture, 256 KB uniform or hybrid sector configuration, and 25-year data retention. It serves as boot code storage in automotive ADAS ECUs requiring high reliability under –40°C to +105°C industrial-plus temperature operation.

For engineers reviewing the S25HL02GTDPBHM053 datasheet, S25HL02GTDPBHM053 pinout, S25HL02GTDPBHM053 application, or S25HL02GTDPBHM053 equivalent, key selection criteria include Quad SPI DDR read throughput (102 MBps), SECDED ECC coverage, EnduraFlex™ partition endurance (2.56M P/E cycles), and hardware reset via dedicated RESET# or DQ3/RESET# configurable pin.

Technical Context

This device implements Infineon's 45-nm MIRRORBIT™ technology storing two bits per cell within a monolithic control logic block managing stacked 1 Gb dies in a single 24-ball BGA package. Its embedded microcontroller handles SFDP parsing, SafeBoot initialization reporting, and OTP secure silicon array access (1024 bytes).

The EnduraFlex™ architecture enables independent endurance tuning across memory partitions: main array supports ≥2,560,000 program-erase cycles while 4 KB sectors guarantee ≥300,000 cycles. CRC-based data integrity checking operates on all read paths, and hardware reset is supported via CS# signaling (JEDEC), dedicated RESET#, or multiplexed DQ3/RESET# pin.

FAQ

What is the maximum Quad SPI DDR read bandwidth supported by S25HL02GTDPBHM053?

The device achieves 102 MBps read throughput using Quad SPI DDR protocol at 102 MHz clock frequency, confirmed in Table 1 of the official Infineon summary datasheet (002-28767 Rev. *A). This requires host controller support for 4S-4D-4D or 4S-4S-4S DDR transaction formats and proper impedance-controlled PCB layout for DQ[3:0] lines.

Does S25HL02GTDPBHM053 support hardware reset through the DQ3 pin?

Yes, DQ3 can be configured as RESET# when Quad SPI is disabled or CS# is HIGH, per Table 5 signal description. The pin has an internal weak pull-up and must be driven LOW to initiate hardware reset. Alternatively, a dedicated RESET# pin is available and functionally identical; both assert internal self-initialization and place DQ[3:0] in high-impedance state.

How does the EnduraFlex™ architecture improve field reliability in automotive applications?

EnduraFlex™ enables independent endurance allocation: 4 KB sectors sustain ≥300,000 program-erase cycles for frequent parameter updates, while 256 KB sectors maintain ≥2,560,000 cycles for infrequently modified boot code. This prevents premature wear-out of critical firmware regions and extends total usable life beyond 15 years in ADAS ECUs operating at +105°C.

Is the 1024-byte OTP secure silicon region write-once or reprogrammable?

The OTP secure silicon region is one-time programmable: each of its 32 × 32-byte pages can be permanently locked after programming, preventing overwrite or readback. Once locked, contents remain tamper-resistant and survive >25 years at +85°C. Programming requires specific command sequences and is irreversible-intended for keys, certificates, or calibration constants.
