Cypress Semiconductor Corp S70FL01GSDPMFV010

Overview

S70FL01GSDPMFV010 from Infineon is a 1 Gbit (128 Mbyte) dual-die SPI flash memory with Multi-I/O interface, 3.0 V core supply, uniform 256-kbyte sectors, and support for Quad DDR read commands. It implements two stacked S25FL512S dies with independent CS1# and CS2# control, enabling discrete die addressing in industrial and automotive systems requiring high-density nonvolatile storage.

For engineers reviewing the S70FL01GSDPMFV010 datasheet, S70FL01GSDPMFV010 pinout, S70FL01GSDPMFV010 application, or S70FL01GSDPMFV010 equivalent, key selection criteria include dual-die address management, sector erase independence per die, OTP array size, AEC-Q100 Grade 2 qualification, and SOIC-16 vs. BGA-24 package compatibility.

Technical Context

The S70FL01GSDPMFV010 integrates two independent 512 Mbit FL-S flash dies sharing a common SPI bus but controlled via separate chip select lines (CS1# and CS2#). Each die maintains its own status register, configuration register, bank address register, and block protection logic.

It supports extended 32-bit addressing, AutoBoot from preselected addresses, Common Flash Interface (CFI) data, and simultaneous die operation only in sequential access mode-not true interleaved reads. VIO is RFU and not supported; I/O voltage range is 1.65–3.6 V, while core operates at 2.7–3.6 V.

FAQ

What is the function of CS1# and CS2# on the S70FL01GSDPMFV010?

CS1# and CS2# are independent chip select inputs that activate the first and second 512 Mbit flash dies respectively. Each die operates autonomously: commands issued while CS1# is asserted affect only Die 1, and those with CS2# active target Die 2. This enables discrete addressing and avoids cross-die interference during programming or erase.

Does the S70FL01GSDPMFV010 support true interleaved reads across both dies?

No. Sequential reads crossing the boundary between Die 1 and Die 2 are not supported. To read across the full 1 Gbit address space, the host must issue separate read commands-first using CS1# for addresses 0x00000000–0x07FFFFFF, then CS2# for 0x08000000–0x0FFFFFFF-with explicit address management.

Is the VIO pin functional on this part?

No. The VIO pin is marked RFU (Reserved for Future Use) and is not supported in the S70FL01GSDPMFV010. I/O voltage is derived solely from VCC (2.7–3.6 V), and the VIO/RFU pin must be left unconnected or tied to VSS per datasheet guidance; it has no electrical function.

How does the OTP array differ from standard flash sectors?

The 2048-byte OTP array is physically isolated and programmed once using dedicated commands. Unlike regular sectors, it cannot be erased or rewritten after programming. It is intended for immutable data such as cryptographic keys, device-specific calibration values, or secure boot signatures-ensuring tamper-resistant storage independent of firmware updates.
