Product details
Overview
S25FL128SAGBHV300 from Cypress Semiconductor is a 128 Mbit (16 MB) 3.0V SPI flash memory IC with Quad I/O and DDR read support, integrated AutoBoot functionality, hardware-based sector protection, and on-die ECC for single-bit error correction. It operates across industrial temperature range (−40°C to +85°C), supports 256-byte and 512-byte page programming, and delivers up to 80 MB/s quad DDR read throughput at 80 MHz.
For engineers reviewing the S25FL128SAGBHV300 datasheet, S25FL128SAGBHV300 pinout, S25FL128SAGBHV300 application, or S25FL128SAGBHV300 equivalent, key selection criteria include hybrid/uniform sector erase configuration, VIO voltage flexibility (1.65–3.6 V), OTP array size (1024 bytes), AEC-Q100 Grade 3 compliance eligibility, and compatibility with legacy S25FL-A/K/P command sets and footprints.
Technical Context
The S25FL128SAGBHV300 implements Cypress's 65 nm MirrorBit Eclipse architecture, enabling faster program/erase cycles via dual-page buffer options (256 B or 512 B) and hybrid sector layout (thirty-two 4 kB parameter sectors + remaining 64 kB sectors) or uniform 256 kB block erase mode. Its SPI Multi-I/O interface supports SIO, DIO, QIO, and DDR variants across clock polarity modes 0 and 3.
It integrates dedicated registers for Advanced Sector Protection (ASP), configurable Block Protection bits (BP2–BP0), TBPROT, and freeze control (CR1[0]) that locks protection state and OTP configuration. The device lacks Deep Power Down but repurposes legacy DPD command (B9h) as bank address register access for 32-bit addressing in 256 Mb variants - though S25FL128SAGBHV300 uses only 24-bit addressing per its density.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 128 Mbit (16 MB) - fixed capacity for boot code storage and firmware image retention in resource-constrained embedded systems. |
| Interface Protocol | SPI Multi-I/O with SIO/DIO/QIO and DDR support - enables scalable bandwidth from 6.25 MB/s (SDR Read) to 80 MB/s (Quad DDR Read) without increasing pin count. |
| Supply Voltage | VCC: 2.7–3.6 V; VIO: 1.65–3.6 V - allows independent I/O rail scaling for mixed-voltage host MCU interfaces while maintaining core stability. |
| Erase Architecture | Hybrid sector option (32 × 4 kB top/bottom + 64 kB main) or uniform 256 kB blocks - ensures backward compatibility with prior S25FL devices and forward software alignment with higher-density families. |
| Program Endurance | 100,000 program-erase cycles - validated minimum endurance for field-updatable firmware partitions requiring frequent reprogramming. |
| Data Retention | 20 years minimum - guarantees long-term integrity of stored boot images and calibration data in unpowered industrial deployments. |
| OTP Array | 1024 bytes one-time programmable memory - provides secure storage for cryptographic keys, device identifiers, or factory-trimmed parameters not modifiable post-deployment. |

Pinout & Package
Package: 24-ball FBGA (6 × 8 mm, FAB024 footprint, Pb-free). Pin assignments are defined per the SOIC-16, WSON, and BGA package drawings in Document 001-98283 Rev. *O, Section 6.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CS# | Chip Select | Active-low enable signal; must transition low before any command sequence; controls device activation and output tristate behavior. |
| SCK | Serial Clock | Master-generated clock; rising edge latches input (SI/IO0–IO3); falling edge (SDR) or both edges (DDR) drive output timing. |
| SI / IO0 | Serial Input / Quad I/O 0 | Primary input for SIO commands; becomes bidirectional I/O0 in DIO/QIO modes for address/data transfer and read response. |
| SO / IO1 | Serial Output / Quad I/O 1 | Primary output for SIO reads; becomes bidirectional I/O1 in DIO/QIO modes for parallel data return during fast read operations. |
| WP# / IO2 | Write Protect / Quad I/O 2 | Hardware lock for Status/Configuration Registers when low and SRWD=1; repurposed as IO2 in Quad mode for expanded I/O width. |
| HOLD# / IO3 | Hold / Quad I/O 3 | Pauses ongoing serial transfer without resetting internal state; repurposed as IO3 in Quad mode to complete 4-bit I/O bus. |
| RESET# | Hardware Reset | Asynchronous active-low reset; forces standby state, clears volatile registers, reloads config, and resets Bank Address Register to zero. |
| VCC | Core Supply | 2.7–3.6 V power for logic and array; decoupling required near package for stable high-speed operation. |
| VIO | I/O Supply | 1.65–3.6 V supply for all I/O pins; enables level-shifting interoperability with 1.8 V or 3.3 V host controllers without external translators. |
| VSS | Ground | Common reference for VCC and VIO; requires low-inductance connection to minimize noise coupling into sensitive SPI timing paths. |
Key Features
| Feature | Design Value |
|---|---|
| AutoBoot Execution | Automatically initiates Normal or Quad Read at preselected address on power-up or RESET#, eliminating host-side boot initialization latency. |
| Integrated ECC Engine | On-the-fly single-bit error correction with hidden syndrome generation per 16-byte group - improves reliability without software overhead or external error-handling logic. |
| Advanced Sector Protection (ASP) | Individual sector lock controlled by boot code or password - enables fine-grained firmware partitioning (e.g., bootloader vs. application) with hardware-enforced write isolation. |
| Extended Addressing Support | 24-bit native addressing (16 MB space fully accessible); optional 32-bit extension available via bank register - future-proofs design for migration to 256 Mb variants using same PCB footprint. |
| Command Set Compatibility | Pin- and command-compatible with S25FL-A, S25FL-K, and S25FL-P families - simplifies drop-in replacement and reduces qualification effort in legacy designs. |
| Hybrid Sector Erase Option | Preserves thirty-two 4 kB sectors at top/bottom address space for parameter storage while using 64 kB sectors elsewhere - maintains compatibility with existing S25FL-K/P firmware layouts. |

FAQ
What is the maximum Quad DDR read throughput supported by the S25FL128SAGBHV300?
The S25FL128SAGBHV300 achieves up to 80 MB/s Quad DDR read throughput at 80 MHz clock rate with VIO = VCC = 3.0–3.6 V. This performance enables real-time streaming of boot code or graphics assets directly from flash without external buffering. The S25FL128SAGBHV300 sustains this rate across its full 16 MB address space under specified operating conditions.
Does the S25FL128SAGBHV300 support hardware reset, and how is it implemented?
Yes, the S25FL128SAGBHV300 includes an active-low RESET# pin that asynchronously forces the device into standby mode, clears volatile registers, resets the Bank Address Register to zero, and reloads internal configuration. The RESET# signal has an internal pull-up resistor and may be left unconnected if unused. This hardware reset is distinct from software reset commands and ensures deterministic recovery after power faults.
How does the AutoBoot feature function in the S25FL128SAGBHV300?
The S25FL128SAGBHV300 AutoBoot feature automatically executes a preconfigured Normal or Quad Read command at power-up or after RESET#, fetching data from a user-defined start address. This eliminates host CPU intervention during initial boot, reducing system startup time and simplifying firmware architecture. Configuration is stored in non-volatile registers and persists across power cycles.
What sector erase options are available on the S25FL128SAGBHV300, and how do they affect firmware layout?
The S25FL128SAGBHV300 offers two erase configurations: hybrid (thirty-two 4 kB sectors at top/bottom + 64 kB main sectors) and uniform (256 kB logical blocks). Hybrid mode preserves compatibility with legacy S25FL-K/P firmware maps, allowing parameter storage in protected 4 kB zones; uniform mode simplifies software management for large firmware images and aligns with future higher-density devices.
Is the S25FL128SAGBHV300 compatible with existing S25FL-P family PCB footprints?
Yes, the S25FL128SAGBHV300 uses the FAB024 24-ball BGA footprint (6 × 8 mm), which matches the physical layout of selected S25FL-P family BGA variants. It is command-set, pinout, and timing compatible with S25FL-P devices, enabling direct PCB-level replacement without redesign - provided the host controller supports DDR and AutoBoot features used in the new implementation.
