Infineon Technologies S28HS02GTFPBHV053

Overview

S28HS02GTFPBHV053 from Infineon Technologies is a 2 Gb (256 MB) Octal SPI NOR Flash memory with dual-die package (DDP), 1.8 V core/I/O supply, industrial-plus temperature grade (–40 °C to +105 °C), and JEDEC JESD251-compliant xSPI interface supporting up to 332 MBps DDR read throughput. It implements MIRRORBIT™ 45-nm technology, SECDED ECC, and ASIL-B functional safety compliance for automotive and industrial boot code storage.

For engineers reviewing the S28HS02GTFPBHV053 datasheet, S28HS02GTFPBHV053 pinout, S28HS02GTFPBHV053 application, or S28HS02GTFPBHV053 equivalent, key selection criteria include octal DDR read performance, ASIL-B safety certification, hybrid sector architecture (32 × 4 KB + remainder 256 KB), 2.56M program-erase cycles, and 24-ball 8 mm × 8 mm BGA packaging with dedicated DS and INT# signals.

Technical Context

This device integrates two 1 Gb MIRRORBIT™ die in a monolithic 24-ball BGA package, with shared control signals (CS#, CK, RESET#, DQ[7:0]) and independent power domains (VCC/VSS for core, VCCQ/VSSQ for I/O). Its embedded algorithm controller (EAC) manages all erase/program operations autonomously, while the host interface controller (HIC) handles protocol-level signaling.

The octal interface supports both SDR (166 MHz, 166 MBps) and DDR (166 MHz, 332 MBps) modes with data strobe (DS) for timing-critical read capture. Sector architecture is configurable as uniform (all 256 KB) or hybrid (32 × 4 KB top/bottom + 256 KB), and page buffer size is selectable between 256 B and 512 B to optimize programming throughput.

FAQ

What is the maximum clock frequency supported in DDR mode?

The S28HS02GTFPBHV053 supports DDR read operations at 166 MHz clock frequency, delivering 332 MBps effective throughput. This is specified under HS-T (1.7–2.0 V) conditions with proper PCB layout for signal integrity. The device automatically detects DDR mode via SFDP and does not require external configuration for clock rate selection.

Does this part include hardware reset functionality?

Yes, the S28HS02GTFPBHV053 includes a dedicated RESET# pin with internal weak pull-up, enabling asynchronous hardware reset to return the device to array read state. During reset, DS and DQ[7:0] enter high-impedance state. This pin is optional - if left unconnected, the internal pull-up ensures default HIGH operation.

How is sector protection implemented?

Sector protection uses two mechanisms: legacy block protection (BP bits in status register) for coarse-grained locking of top/bottom memory regions, and advanced sector protection (ASP) for individual 4 KB or 256 KB sector locking via dedicated ASP registers. Both are nonvolatile and survive power cycles, enabling secure firmware partitioning.

Is the 24-ball BGA package compatible with standard reflow profiles?

Yes, the 24-ball BGA package complies with IPC/JEDEC J-STD-020 moisture sensitivity level 3 and supports standard lead-free reflow profiles. However, exposure to ultrasonic cleaning or sustained temperatures above 150 °C must be avoided to prevent package damage or data corruption, as explicitly warned in the official datasheet.
