Product details
Overview
SST39WF800A-90-4C-M2QE from Silicon Storage Technology is an 8 Mbit (512K × 16) single-supply Multi-Purpose Flash memory IC with 1.65–1.95 V operation, 90 ns read access time, and SuperFlash® technology enabling 100,000 program/erase cycles and >100-year data retention. It serves as nonvolatile program/data storage in embedded controllers requiring low-voltage, sector/block-erasable flash with JEDEC-standard x16 interface.
For engineers reviewing the SST39WF800A-90-4C-M2QE datasheet, SST39WF800A-90-4C-M2QE pinout, SST39WF800A-90-4C-M2QE application, or SST39WF800A-90-4C-M2QE equivalent, this page delivers verified electrical specs, package mapping to 48-ball WFBGA (5 mm × 6 mm), JEDEC-compliant command set details, and real-world use context for firmware update, configuration storage, and boot code retention in space-constrained industrial and automotive systems.
Technical Context
The SST39WF800A-90-4C-M2QE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, delivering fixed erase/program timing independent of cycle count. Its x16 asynchronous interface supports CE#/OE#/WE# control logic and latched address/data buses compliant with JEDEC standard pinouts for flash EEPROMs.
It features dual software write-detection mechanisms-Data# Polling (DQ7) and Toggle Bit (DQ6)-with valid status reporting after the fourth (program) or sixth (erase) WE#/CE# pulse edge. Internal VPP generation eliminates external high-voltage requirements, and hardware protection includes noise/glitch immunity (<5 ns pulse rejection) and VDD power-up/down detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16 organization), providing 1 MB of byte-addressable nonvolatile storage |
| Supply Voltage | 1.65–1.95 V - enables direct integration into 1.8 V system rails without level-shifting |
| Read Access Time | 90 ns - supports high-speed instruction fetch and data read in real-time embedded applications |
| Endurance | 100,000 program/erase cycles - validated per JEDEC A117, suitable for frequent firmware updates |
| Data Retention | >100 years at 25°C - meets long-life requirements for unattended industrial equipment |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) - enables fine-grained field updates without full chip erase |
| Program Time | 28 µs typical word-program - reduces firmware patch latency vs. conventional NOR flash |
| Standby Current | 5 µA typical - minimizes quiescent power in battery-backed or always-on systems |
Pinout & Package
Package: 48-ball WFBGA (5 mm × 6 mm), RoHS-compliant, lead-free micro-package with bottom-side ball layout per Figure 2.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | A0–A17 select 512K words; A18 (AMS) is most-significant address used for sector/block selection during erase |
| DQ0–DQ15 | Data I/O | x16 bidirectional bus: outputs valid data during read, accepts program data during write, tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low device select: asserts internal logic only when low; high state forces standby mode (5 µA) |
| OE# | Output Enable | Active-low output gate: controls DQ bus drive; high disables outputs to high-impedance state |
| WE# | Write Enable | Active-low control for write operations: latches address/data on falling/rising edges per JEDEC timing rules |
| VDD | Power Supply | 1.65–1.95 V core supply; powers all internal logic and SuperFlash array |
| VSS | Ground | Reference return path for all signals and internal circuitry |
| NC | No Connection | Unbonded balls (e.g., A1, C1, D1, E1, F1, G1, H1, J1, K1, L1 per Figure 2); must be left floating |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell with thick-oxide injector enables fixed 28 µs program and 36 ms erase times across full endurance life |
| JEDEC-Compliant Interface | Standard x16 pinout and command set (e.g., 6-byte sector erase: 5555H/AAH → 2AAAH/55H → 5555H/80H → 5555H/AAH → 2AAAH/55H → SAX/30H) |
| Hardware + Software Data Protection | Glitch immunity (<5 ns), VDD lockout (<1.0 V), and mandatory 3-byte (program) / 6-byte (erase) SDP sequences prevent accidental writes |
| CFI Query Support | Accessible via 5555H/AAH → 2AAAH/55H → 5555H/98H; returns device geometry, timing, and voltage parameters at standardized offsets |
| Low-Power Erase/Program | Consumes less total energy than alternative flash due to lower current draw and shorter fixed timing - critical for energy-constrained edge nodes |
| Product Identification Mode | Software ID entry (5555H/AAH → 2AAAH/55H → 5555H/90H) reads Manufacturer ID (00BFH) and Device ID (273FH) for multi-vendor socket validation |
Applications

IC Role / Device Role / Timing Role: High-reliability nonvolatile archive memory; written once at production, read throughout product service life. Use Value: 100,000-cycle endurance exceeds recalibration frequency; SuperFlash fixed timing ensures consistent write verification across decades. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV800CTTI-90G | 3.0 V supply (2.7–3.6 V), 8 Mbit x16, 90 ns access, CFI-compatible but lacks SuperFlash fixed-timing guarantee | Requires separate 3.0 V rail; higher active current (15 mA vs. 5 mA) limits battery use | Select when legacy 3.0 V system compatibility is mandatory and endurance >50k cycles is acceptable |
| S29GL064N90TFI010 | 3.0 V supply, 64 Mbit x16, 90 ns, enhanced ECC and sector protection; no 1.8 V option | Higher density but incompatible voltage range; not drop-in for 1.8 V designs | Choose for scalable future-proofing in new 3.0 V platforms needing larger code space and advanced error handling |
Compared with MX29LV800CTTI-90G and S29GL064N90TFI010, the SST39WF800A-90-4C-M2QE uniquely delivers 1.8 V operation, ultra-low 5 µA standby, and cycle-independent timing - making it the only viable choice for compact, battery-sensitive, or mixed-voltage embedded systems requiring guaranteed long-term reliability.

FAQ
What is the operating voltage range for the SST39WF800A-90-4C-M2QE?
The SST39WF800A-90-4C-M2QE operates exclusively within a 1.65 V to 1.95 V supply range, optimized for 1.8 V nominal systems. This single-supply requirement eliminates need for external voltage translators or charge pumps, and is validated across commercial (0°C to +70°C) and industrial (−40°C to +85°C) temperature grades. Operation outside this range may cause functional failure or data corruption.
Does the SST39WF800A-90-4C-M2QE support JEDEC-standard commands?
Yes, the SST39WF800A-90-4C-M2QE fully complies with JEDEC standard pinouts and command sets for x16 flash memories. It implements mandatory sequences including Word-Program (5555H/AAH → 2AAAH/55H → 5555H/A0H), Sector-Erase (six-byte sequence ending in SA/30H), and CFI Query (5555H/AAH → 2AAAH/55H → 5555H/98H), all documented in its official EOL datasheet.
How is write completion detected on the SST39WF800A-90-4C-M2QE?
The SST39WF800A-90-4C-M2QE provides two hardware-supported methods: Data# Polling (DQ7 toggles complement/data state) and Toggle Bit (DQ6 alternates 1/0 until operation completes). Both are valid after the fourth WE#/CE# pulse edge for programming and sixth edge for erasing - enabling efficient polling without timer dependencies in host firmware.
What package type does the SST39WF800A-90-4C-M2QE use?
The SST39WF800A-90-4C-M2QE uses a 48-ball WFBGA (5 mm × 6 mm) micro-package with bottom-side solder balls, as confirmed in Figure 2 of the datasheet. This RoHS-compliant, lead-free package supports fine-pitch surface-mount assembly and thermal performance suitable for dense PCB layouts in industrial and automotive modules.
Is the SST39WF800A-90-4C-M2QE still in production?
No - the SST39WF800A-90-4C-M2QE is an End-of-Life (EOL) device, as indicated by document number S71258-08-EOL and January 2010 revision date. However, Aetrix Electronics maintains legacy inventory with full traceability and offers lifecycle coordination support, including cross-reference guidance and obsolescence mitigation planning for ongoing production programs.
