Product details
Overview
SST39WF800B-70-4I-MAQE from Microchip Technology is a 8 Mbit (512K × 16) Multi-Purpose Flash memory IC using SuperFlash technology, designed for embedded program/data storage in low-voltage systems. It operates from 1.65–1.95 V, delivers 70 ns read access time, supports sector/block/chip erase, and features hardware/software data protection. It is used in firmware update modules requiring reliable nonvolatile storage with fast write timing.
For engineers reviewing the SST39WF800B-70-4I-MAQE datasheet, SST39WF800B-70-4I-MAQE pinout, SST39WF800B-70-4I-MAQE application, or SST39WF800B-70-4I-MAQE equivalent, this page provides verified technical context, JEDEC-compliant x16 interface details, SuperFlash endurance and retention specs, 48-ball WFBGA package mapping, and real-world use cases in industrial controllers and boot memory subsystems.
Technical Context
The SST39WF800B-70-4I-MAQE implements an asynchronous x16 parallel interface with JEDEC-standard command sets and CFI support. Its split-gate SuperFlash cell enables fixed 28 µs word-program and 36 ms sector/block-erase times independent of cycle count - eliminating software de-rating over lifetime.
It uses dual status detection (DQ7 Data# Polling and DQ6 Toggle Bit) for end-of-write verification and integrates noise/glitch protection, VDD power-up/down detection, and JEDEC-approved Software Data Protection (SDP) with three-byte program and six-byte erase sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 512K × 16 (8 Mbit total); enables direct connection to 16-bit microcontroller data buses without glue logic. |
| Read Access Time | 70 ns; meets timing requirements for high-speed boot code execution in ARM Cortex-M and RISC-V SoCs. |
| Supply Voltage | 1.65–1.95 V; compatible with modern low-power SoC I/O domains and eliminates need for level shifters. |
| Endurance | 10,000 cycles minimum (JEDEC A117); sufficient for field firmware updates in industrial gateways and PLCs. |
| Data Retention | 100 years minimum (JEDEC A103); ensures long-term reliability in unattended infrastructure equipment. |
| Erase Granularity | Uniform 2 KWord sectors and 32 KWord blocks; allows selective firmware patching without full chip reprogramming. |
| Write Timing | 28 µs typical word-program; reduces system latency during configuration writes in real-time control loops. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, surface-mountable with standard reflow profile (260°C/10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | A0–A17 select 512K words; A18 (AMS) enables sector/block address decoding per JEDEC command protocol. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; latched internally during write; tri-stated when CE# or OE# is high. |
| CE# | Chip Enable | Active-low device selection; must be low for read/write; high-Z output state when asserted high. |
| OE# | Output Enable | Active-low output gating; controls data bus drive; used with CE# to enable valid read data. |
| WE# | Write Enable | Active-low write control; initiates internal program/erase operations on rising edge per JEDEC sequence. |
| VDD | Power Supply | 1.65–1.95 V supply; powers core and I/O; requires local decoupling due to fast switching currents. |
| VSS | Ground | Two dedicated ground balls (pins E1, L6); critical for noise immunity in high-speed read/write transitions. |
| NC | No Connection | Unbonded pins (e.g., B1, C1, D1); must remain floating - no external tie or pull-up/down. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide tunneling injector enables fixed 28 µs program and 36 ms erase times across full lifecycle - no software adaptation needed. |
| JEDEC x16 Interface Compliance | Fully compatible with industry-standard flash command sets and pinouts; drop-in replacement for legacy x16 parallel NOR devices in existing PCB layouts. |
| Hardware + Software Data Protection | Glitch filtering (<5 ns), VDD monitoring (<1.0 V inhibit), and JEDEC SDP prevent accidental writes during power ramp or EMI events. |
| CFI Query Support | Supports both SST-specific and general CFI modes (via 5555H/98H or 55H/98H), enabling automatic driver detection in Linux MTD and U-Boot environments. |
| Low Standby Current | Typical 5 µA (max 40 µA); extends battery life in always-on IoT edge nodes and remote sensor concentrators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-70-4C-B3KE | Same 8 Mbit x16 organization and SuperFlash architecture, but rated for commercial temperature (0°C to +70°C) and uses 48-ball TFBGA (6 mm × 8 mm) package. | Lacks industrial-grade temp range; larger footprint may require PCB redesign; identical command set and timing. | Select only for cost-sensitive consumer applications where ambient temperature stays below 70°C and board space permits larger package. |
| MX29LV800CTTI-70G | 8 Mbit x16 CMOS flash with 70 ns access, but uses conventional floating-gate technology; higher program current (20 mA vs. 5 mA active), no CFI support, and 100k-cycle endurance. | Higher power consumption limits use in battery-backed systems; lacks SDP and CFI, complicating driver portability. | Consider only if legacy design already uses MX29LV family and CFI/low-voltage operation is not required. |
Compared with SST39VF800A-70-4C-B3KE, the SST39WF800B-70-4I-MAQE adds industrial temperature support and smaller WFBGA packaging; versus MX29LV800CTTI-70G, it delivers lower voltage operation, superior endurance consistency, and standardized CFI identification - critical for scalable firmware development.

FAQ
What is the operating temperature range for SST39WF800B-70-4I-MAQE?
The SST39WF800B-70-4I-MAQE is rated for industrial temperature operation from –40°C to +85°C, making it suitable for deployment in harsh environments such as factory floors, outdoor utility meters, and automotive under-hood applications. This range is validated per JEDEC JESD22-A104 and specified in Table 8 of the DS25031A datasheet.
Does SST39WF800B-70-4I-MAQE support Common Flash Interface (CFI)?
Yes, SST39WF800B-70-4I-MAQE supports both SST-specific and general CFI Query modes. Entering CFI mode via 5555H/98H (SST mode) or 55H/98H (general mode) allows host systems to auto-detect geometry, timing, and command set - essential for generic flash drivers in Linux and U-Boot. CFI data is accessible at addresses defined in Tables 5–7.
How does the Software Data Protection (SDP) work on SST39WF800B-70-4I-MAQE?
SST39WF800B-70-4I-MAQE implements JEDEC-approved SDP: Word-Program requires a three-byte unlock sequence (5555H/AAH → 2AAAH/55H → 5555H/A0H), while Erase commands require six-byte sequences. The device ships with SDP permanently enabled. Invalid sequences abort to Read mode within TRC (150 ns), preventing accidental writes during power transients.
What package type is used by SST39WF800B-70-4I-MAQE?
SST39WF800B-70-4I-MAQE uses a 48-ball WFBGA package measuring 4 mm × 6 mm. This micro-package variant offers reduced footprint and thermal resistance compared to TFBGA, and is explicitly listed in the "Packages Available" section of the DS25031A datasheet alongside pin assignments in Figure 2.
Can SST39WF800B-70-4I-MAQE be used as a direct replacement for SST39VF800A in existing designs?
SST39WF800B-70-4I-MAQE shares identical pinout, command set, and AC/DC specifications with SST39VF800A, but adds industrial temperature rating and uses WFBGA instead of TFBGA. A direct replacement is possible only if the PCB layout accommodates the smaller 4 mm × 6 mm WFBGA footprint and the application requires –40°C to +85°C operation.
