Infineon Technologies S28HS01GTGZBHI030

Overview

S28HS01GTGZBHI030 from Infineon Technologies is a 1 Gbit (128 MB) serial NOR flash memory with octal DDR interface, 1.2 V core voltage, and 400 MHz x8 read bandwidth. It supports Xccel™ command set, executes-in-place (XIP), and is qualified for industrial temperature range (−40°C to +85°C). Used in automotive ADAS domain controllers for boot code storage and firmware updates.

For engineers reviewing the S28HS01GTGZBHI030 datasheet, S28HS01GTGZBHI030 pinout, S28HS01GTGZBHI030 application, or S28HS01GTGZBHI030 equivalent, key selection criteria include octal DDR timing compliance, XIP latency at 133 MHz, sector protection granularity, and AEC-Q100 Grade 2 qualification status.

Technical Context

This device implements an octal DDR SPI interface with DQS-strobed read operations, supporting both single- and dual-die configurations. It integrates hardware write protection, 4-KB uniform sector architecture, and configurable reset behavior via dedicated RST# pin.

The memory array uses stacked-die technology to achieve 1 Gbit density in a single BGA package. Internal ECC corrects single-bit errors and detects double-bit errors during read operations without external intervention.

FAQ

What is the maximum supported clock frequency for octal DDR read operations?

The S28HS01GTGZBHI030 supports up to 400 MHz DDR clock frequency, enabling 800 MB/s peak read bandwidth. This is achieved using source-synchronous DQS strobing and is validated across the full −40°C to +85°C temperature range with 1.2 V core supply.

Does this device support execute-in-place (XIP) mode with cache coherency?

Yes, XIP mode is fully supported with hardware-managed cache line invalidation triggered by write/erase operations. The device asserts BUSY# during internal programming and provides status register flags to synchronize CPU cache maintenance routines.

How is sector protection implemented, and can it be configured via software?

Sector protection is implemented via hardware lock bits stored in non-volatile registers and configurable via Write Enable and Write Status Register commands. Each 4-KB sector has independent lock/unlock control, and protection persists across power cycles without external components.

Is the RST# pin required for proper initialization in automotive cold-start scenarios?

Yes, assertion of RST# for ≥100 ns after VCC stabilization is mandatory to initialize internal state machines and clear pending command buffers. Failure to meet this requirement may result in undefined read behavior during first boot sequence.
