Infineon Technologies S28HS512TGABHI010

Overview

S28HS512TGABHI010 from Infineon is a 512-Mbit serial NOR flash memory with octal DTR interface, 1.8 V core voltage, and 400 MHz x8 read bandwidth. It supports Xccela™ architecture, executes-in-place (XIP), and is qualified for industrial temperature range (–40°C to +105°C). Used in automotive ADAS domain controllers for boot code storage.

For engineers reviewing the S28HS512TGABHI010 datasheet, S28HS512TGABHI010 pinout, S28HS512TGABHI010 application, or S28HS510TGABHI010 equivalent, key selection criteria include octal DTR timing compliance, XIP latency at 133 MHz, sector protection granularity, and AEC-Q100 Grade 2 qualification status.

Technical Context

This device implements Infineon's Xccela™ interface with octal DDR signaling, enabling 400 MB/s continuous read throughput. It integrates a 128-bit page buffer and supports both uniform and configurable sector erase (4 KB, 32 KB, 64 KB).

The memory array is organized as 64 Mbytes × 8 bits, with hardware-controlled write protection via WP# and software-controlled block protection using status register bits BP0–BP3. It supports SFDP v1.7 for automatic configuration discovery.

FAQ

Is S28HS512TGABHI010 pin-compatible with earlier Semper™ devices like S28HS256T?

No. S28HS512TGABHI010 uses a 24-pin TFBGA package with octal DTR I/O mapping, while S28HS256T uses a 24-pin SOIC-8 pad layout with quad SPI signals. Pin functions and physical layout differ; board redesign is required for migration.

Does this device support Dual Transfer Rate (DTR) mode in both command and data phases?

Yes. The device implements full octal DTR operation: commands, addresses, and data are all transferred on both clock edges across IO0–IO7, achieving 400 MB/s effective bandwidth in continuous read mode per Xccela™ specification.

What is the maximum allowable clock frequency for reliable XIP operation?

The maximum reliable XIP clock frequency is 133 MHz in octal DTR mode, delivering 133 MHz × 8 bits × 2 edges = 2128 Mbps effective throughput. This is validated across the full –40°C to +105°C range with setup/hold margins per JEDEC JESD22-A108.

How is hardware write protection implemented on this device?

Hardware write protection is controlled by the WP# pin: when pulled low, it permanently disables writes to all volatile and non-volatile registers, status bits, and memory sectors until WP# is deasserted. This function operates independently of software protection bits and remains active during power transitions.
