Product details
Overview
SST39VF800A-70-4C-MAQE from Microchip Technology is an 8 Mbit (512K x 16) CMOS Multi-Purpose Flash memory IC using SuperFlash technology, operating at 2.7–3.6 V with 70 ns read access time, 14 µs word-program time, and JEDEC-standard x16 asynchronous interface. It serves as nonvolatile program/data storage in embedded controllers, firmware boot loaders, and industrial HMI systems.
For engineers reviewing the SST39VF800A-70-4C-MAQE datasheet, SST39VF800A-70-4C-MAQE pinout, SST39VF800A-70-4C-MAQE application, or SST39VF800A-70-4C-MAQE equivalent, key selection criteria include its 2.7 V minimum VDD support, uniform 2 KWord sector/32 KWord block erase architecture, toggle-bit/data# polling write completion detection, and 48-ball WFBGA (4 mm × 6 mm) RoHS-compliant packaging.
Technical Context
The SST39VF800A-70-4C-MAQE implements a split-gate SuperFlash cell with thick-oxide tunneling injector for enhanced endurance and data retention. Its command-set architecture requires six-byte sequences for sector/block/chip erase and three-byte sequences for word-program, all compliant with JEDEC standard pinouts and CFI query capability.
It supports hardware write inhibit via CE#/OE#/WE# logic states and software data protection (SDP) with permanent enablement at shipment. The device uses latched address/data bus timing, tri-state outputs controlled by CE# and OE#, and internal VPP generation-eliminating external high-voltage programming supplies.

| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; latched during writes; tri-stated when CE# or OE# is high |
| CE# | Chip Enable | Active-low chip select - disables device and reduces current to 20 µA standby when high |
| OE# | Output Enable | Active-low output gate - controls data bus visibility without affecting internal state |
| WE# | Write Enable | Active-low control for program/erase command latching and timing initiation |
| VDD | Power Supply | 2.7–3.6 V supply; powers core logic and charge pump for internal VPP generation |
| VSS | Ground | Two dedicated ground balls - ensures stable reference for noise-sensitive flash operations |
| NC | No Connect | Unbonded pins (e.g., A17, A18, multiple NC positions) - must be left floating or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash cell technology | Split-gate structure with thick-oxide injector enables fixed 14 µs program/18 ms erase times across full lifecycle |
| JEDEC-standard command set | Fully compatible with industry-standard x16 flash controllers and bootloader firmware without custom drivers |
| Hardware + Software Data Protection | Glitch filtering, VDD monitoring, and permanent SDP prevent accidental writes during power transitions |
| CFI Query support | Enables automatic runtime identification of density, timing, and erase geometry - critical for generic flash abstraction layers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-70-4C-EQE | Same die and timing, but in 48-ball TFBGA (6 mm × 8 mm) package - larger footprint, different ball pitch | Requires PCB redesign due to incompatible pad layout and thermal profile; identical firmware compatibility | Select when board space allows larger package or thermal dissipation requirements exceed WFBGA limits |
| MX29LV800CTTC-70G | 8 Mbit x16 flash with 70 ns access, but uses traditional floating-gate architecture; 10,000-cycle endurance vs. 100,000 | Limited rewrite cycles constrain use in frequently updated configurations; no CFI query support | Choose only for legacy designs where pinout matches and endurance demands are low |
Compared with SST39VF800A-70-4C-EQE, the MAQE variant offers superior board-area efficiency and lower thermal resistance; versus MX29LV800CTTC-70G, it delivers tenfold endurance and standardized CFI interrogation-critical for field-serviceable embedded systems.

FAQ
What is the exact memory organization of the SST39VF800A-70-4C-MAQE?
The SST39VF800A-70-4C-MAQE is organized as 512K words × 16 bits (8 Mbit total), with address lines A0–A15 selecting individual words and A16 serving as the most-significant address (AMS) for sector/block erase targeting. This x16 configuration maps directly to 16-bit microprocessor data buses without byte-lane multiplexing.
Does the SST39VF800A-70-4C-MAQE require an external VPP voltage for programming?
No. The SST39VF800A-70-4C-MAQE integrates an internal charge pump that generates the required high-voltage programming signal (VPP) from the 2.7–3.6 V VDD supply. This eliminates the need for external high-voltage circuitry, simplifying board design and reducing BOM count.
How does write completion detection work on the SST39VF800A-70-4C-MAQE?
The SST39VF800A-70-4C-MAQE provides two hardware-supported methods: Data# Polling (DQ7 toggles until operation completes, then reflects true data) and Toggle Bit (DQ6 alternates between 0 and 1 during operation, then stabilizes). Both are valid after the rising edge of the fourth WE# pulse for programming and sixth for erasing.
Is the SST39VF800A-70-4C-MAQE compatible with standard JEDEC x16 flash controllers?
Yes. The SST39VF800A-70-4C-MAQE conforms fully to JEDEC standard pinouts, command sets, and timing specifications for x16 asynchronous flash devices. It supports common operations including word-program, sector/block/chip erase, and CFI query without proprietary extensions.
What package type is used for the SST39VF800A-70-4C-MAQE, and what are its key mechanical attributes?
The SST39VF800A-70-4C-MAQE uses a 48-ball WFBGA (Wafer-Level Fine-Pitch Ball Grid Array) package measuring 4 mm × 6 mm with 0.5 mm ball pitch. It features exposed die attach pad for thermal performance and complies with RoHS and lead-free solder reflow standards (260°C for 10 seconds).
