Infineon Technologies S28HS02GTFPBHV050

Overview

S28HS02GTFPBHV050 from Infineon is a 2 Gb (256 MB) Octal SPI NOR Flash memory in a 24-ball BGA (8 mm × 8 mm) package, built on 45-nm MIRRORBIT™ technology with dual-die MCP architecture. It supports JEDEC JESD251-compliant Octal xSPI interface (SDR up to 166 MHz / 166 MBps, DDR up to 166 MHz / 332 MBps), includes 256 KB uniform or hybrid sector architecture, 512-byte page buffer, and integrated SECDED ECC for main array data integrity.

For engineers reviewing the S28HS02GTFPBHV050 datasheet, S28HS02GTFPBHV050 pinout, S28HS02GTFPBHV050 application, or S28HS02GTFPBHV050 equivalent, key selection criteria include ASIL-B functional safety compliance, 2.56M program-erase cycles, 25-year data retention, 1.7–2.0 V / 2.7–3.6 V dual-voltage operation, and hardware reset via dedicated RESET# pin or CS# signaling.

Technical Context

This device implements a dual-die multi-chip package (DDP) with internally tied control signals across both 1 Gb dies, enabling unified command execution and seamless address mapping. Its embedded algorithm controller (EAC) manages all erase/program operations autonomously, while the host interface controller (HIC) handles real-time signal monitoring and data transfer coordination.

The octal interface operates in both SDR and DDR modes with data strobe (DS) support for precise read capture; it also maintains full backward compatibility with legacy 1-bit SPI. Sector architecture is configurable as uniform (all 256 KB) or hybrid (32 × 4 KB + remaining 256 KB sectors), and the OTP secure silicon region provides 1024 bytes of one-time-programmable storage for keys or configuration.

FAQ

What voltage ranges does the S28HS02GTFPBHV050 support?

The S28HS02GTFPBHV050 supports two independent voltage domains: HS-T mode (1.7–2.0 V for both VCC and VCCQ) and HL-T mode (2.7–3.6 V for both VCC and VCCQ). It is not designed for mixed-voltage operation - both supplies must be within the same specified range. The "HV" suffix in the part number indicates high-voltage (HL-T) capability, confirmed by its rated 2.7–3.6 V operation and -40 °C to +105 °C industrial-plus temperature grade.

Does this device require external hardware for ECC correction?

No. The S28HS02GTFPBHV050 integrates on-die SECDED (Single Error Correction, Double Error Detection) logic that automatically corrects single-bit errors and detects double-bit errors during read operations across the main memory array. This correction occurs transparently in hardware without CPU intervention or external circuitry, and is enabled by default at power-on - no configuration register setting is required to activate basic ECC functionality.

Can the 4 KB sectors be placed exclusively at the top or bottom of the address space?

Yes. The S28HS02GTFPBHV050 supports three sector architecture configurations: uniform (all 256 KB), hybrid grouped (32 × 4 KB sectors either at top or bottom only), and hybrid split (32 × 4 KB sectors at both top and bottom). This is controlled via nonvolatile configuration registers and can be set once during manufacturing or field programming - enabling flexible allocation of small-sector regions for bootloader or parameter storage without affecting larger firmware partitions.

Is the RESET# pin mandatory for functional safety compliance?

No - RESET# is optional per datasheet Table 1, but its presence enables hardware-initiated SafeBoot recovery independent of CS# timing. For ISO 26262 ASIL-B compliance, Infineon's safety manual specifies that either RESET# assertion or CS#-driven reset may be used to initiate the SafeBoot sequence; however, using the dedicated RESET# pin provides stronger fault isolation and is recommended for systems where CS# timing cannot be guaranteed during power transients or brown-out conditions.
