Infineon Technologies S70FL01GSDSBHMC10

Overview

S70FL01GSDSBHMC10 from Infineon is a 1 Gbit (128 Mbyte) dual-die stacked SPI Multi-I/O flash memory with 3.0 V core supply, uniform 256-kbyte sectors, 100,000 program-erase cycles, and AEC-Q100 Grade 2 automotive qualification (−40°C to +105°C). It supports Quad DDR read, AutoBoot, CFI configuration, and OTP array (2048 bytes) for secure firmware storage in automotive ADAS controllers.

For engineers reviewing the S70FL01GSDSBHMC10 datasheet, S70FL01GSDSBHMC10 pinout, S70FL01GSDSBHMC10 application, or S70FL01GSDSBHMC10 equivalent, key selection criteria include dual-die independent chip select operation (CS1#/CS2#), 2.7–3.6 V core voltage tolerance, sector-level block protection with FREEZE bit control, and compatibility with S25FL-P family command sets and footprints.

Technical Context

The S70FL01GSDSBHMC10 implements a dual-die stack of two S25FL512S dies sharing a common SOIC-16 package but operating independently via dedicated chip selects (CS1# and CS2#). Each die maintains separate status, configuration, bank address, security, and block protection registers - requiring discrete command issuance per die for programming, erase, and register updates.

It supports SPI modes 0 and 3, DDR timing with data learning, extended 32-bit addressing, and simultaneous multi-I/O operations (Dual/Quad/DDR) on SI/IO0, SO/IO1, WP#/IO2, and HOLD#/IO3. VIO is RFU and not supported; I/O levels are referenced to VCC only (1.65–3.6 V compatible).

FAQ

Is S70FL01GSDSBHMC10 pin-compatible with S25FL512S?

No. The S70FL01GSDSBHMC10 is a dual-die stack packaged in SOIC-16 with dedicated CS1# and CS2# pins, whereas the S25FL512S is a single-die 512 Mbit device. Pin functions differ: CS1# and CS2# replace NC and DNU pins present on S25FL512S SOIC variants, and RESET# behavior is synchronized across both dies.

Can S70FL01GSDSBHMC10 perform simultaneous reads from both dies?

No. The device does not support true simultaneous die access. While CS1# and CS2# allow independent selection, only one die may be active per SPI transaction. Sequential reads across die boundaries require explicit CS# toggling and separate command sequences - no hardware interleaving or auto-wraparound is implemented.

What happens if the FREEZE bit is set on one die but not the other?

Each die maintains its own FREEZE bit state. If FREEZE=1 on die 1 and FREEZE=0 on die 2, only die 1's block protection settings become immutable until power-on-reset. Die 2 remains configurable. This asymmetry enables staged security lockdown - e.g., freezing production firmware on die 1 while retaining field-upgrade capability on die 2.

Does S70FL01GSDSBHMC10 support octal SPI or Xccela interface?

No. It supports only standard and enhanced SPI protocols: single, dual, quad, and DDR variants. There is no octal I/O capability, no Xccela command set, and no HyperBus or Octal DDR support. The maximum interface width is four I/O lines (IO0–IO3), and all commands conform to JEDEC JESD216-compliant SPI flash standards.
