Infineon Technologies S25HL02GTDPBHV053

Overview

S25HL02GTDPBHV053 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 sector erase capability. It delivers up to 102 MBps DDR read throughput, features 256-byte or 512-byte page programming buffers, and integrates SECDED ECC for single-bit correction and double-bit detection-used in automotive ADAS boot code storage and industrial controller firmware retention.

For engineers reviewing the S25HL02GTDPBHV053 datasheet, S25HL02GTDPBHV053 pinout, S25HL02GTDPBHV053 application, or S25HL02GTDPBHV053 equivalent, key selection criteria include ASIL-B functional safety certification, hybrid sector architecture (4 KB + 256 KB), 2.7–3.6 V / 1.7–2.0 V dual-voltage operation, 25-year data retention, and BGA-24 package compatibility with high-density PCB layouts.

Technical Context

This device implements Infineon's 45-nm MIRRORBIT™ technology storing two bits per cell and uses EnduraFlex™ architecture to partition endurance and retention across memory regions. Its embedded microcontroller manages SafeBoot initialization reporting, CRC-based array integrity checks, and OTP secure silicon (1024 bytes) for configuration locking.

The Quad SPI interface supports five protocols-including 1S-4D-4D and 4S-4D-4D-with DDR mode enabling 102 MBps reads at 102 MHz. Sector protection includes legacy block-level and advanced per-sector write lock, while hardware reset is implemented via dedicated RESET# pin or CS# signaling per JEDEC standards.

FAQ

What voltage ranges does the S25HL02GTDPBHV053 support?

The device operates across two distinct supply rails: 1.7–2.0 V (HS-T grade) and 2.7–3.6 V (HL-T grade). This dual-voltage capability allows direct integration into mixed-supply systems without level-shifting circuitry, and each rail is independently validated for timing, endurance, and retention specifications per datasheet Table 3 and Table 4.

Does the S25HL02GTDPBHV053 require external hardware reset circuitry?

No. The device includes a dedicated RESET# pin with internal weak pull-up, allowing it to self-initialize on power-up without external RC networks. When driven LOW, it forces SafeBoot revalidation and returns to array read state; if left unconnected, the internal pull-up holds it HIGH, enabling normal operation after power stabilization.

How does the hybrid sector architecture benefit firmware update strategies?

The hybrid configuration-32 × 4 KB sectors at top/bottom plus uniform 256 KB sectors-enables atomic updates of critical vectors (e.g., interrupt table, boot loader) in small sectors while storing bulk application code in larger sectors. This minimizes erase time and wear during partial updates, extending effective lifetime beyond 2.5M cycles in real-world field deployments.

Is the OTP Secure Silicon region accessible after initial programming?

Yes, but only for read operations. The 1024-byte OTP array is one-time programmable: once written, bits can only be changed from '1' to '0', not reversed. It supports secure key storage, device ID binding, and configuration lockdown, and its contents are verified during SafeBoot to prevent unauthorized firmware substitution.
