Product details
Overview
SST39VF800A-90-4I-B3KE from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC using SuperFlash technology, operating at 2.7–3.6V 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, industrial HMIs, and legacy BIOS modules.
For engineers reviewing the SST39VF800A-90-4I-B3KE datasheet, SST39VF800A-90-4I-B3KE pinout, SST39VF800A-90-4I-B3KE application, or SST39VF800A-90-4I-B3KE equivalent, key selection criteria include its 2.7V minimum VDD operation, uniform 2 KWord sector/32 KWord block erase architecture, 100,000-cycle endurance, and compatibility with standard x16 parallel bus microcontrollers.
Technical Context
The SST39VF800A-90-4I-B3KE implements a split-gate SuperFlash cell with thick-oxide tunneling injector for enhanced reliability and fixed erase/program timing independent of cycle count. 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 flash pinouts and software data protection (SDP).
It supports dual status detection via Data# Polling (DQ7) and Toggle Bit (DQ6), operates in Read, Program, Sector-Erase, Block-Erase, Chip-Erase, and CFI Query modes, and features hardware write-inhibit during power-up/down and noise/glitch immunity on WE#/CE# pins.

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-B3KE | 70 ns read access (same), but Commercial temp range (0°C to +70°C) vs. Industrial (-40°C to +85°C) | Not qualified for automotive or outdoor industrial use; lower cost for consumer-grade embedded systems | Select only if ambient operating temperature remains within 0–70°C and qualification to AEC-Q100 or IEC 60730 is not required |
| MX29LV800CTTI-70G | 8 Mbit x16, 70 ns, 3.0–3.6V supply; lacks SuperFlash fixed-timing; slower 500 ms chip-erase vs. 70 ms | Higher active current (25 mA vs. 9 mA); less suitable for battery-backed or thermally constrained designs | Consider only when existing PCB layout uses MX29LV pinout and SuperFlash timing predictability is not critical |
Compared with SST39VF800A-90-4I-B3KE, the -70-4C variant sacrifices industrial temperature support for lower cost, while the MX29LV800CTTI-70G trades SuperFlash reliability and low-power efficiency for broader second-source availability - neither offers identical endurance, retention, or low-voltage margin.

FAQ
What is the exact memory organization of the SST39VF800A-90-4I-B3KE?
The SST39VF800A-90-4I-B3KE is organized as 512K words × 16 bits, totaling 8 Mbit (1,048,576 bytes) of addressable nonvolatile storage. This x16 configuration maps directly to 19-bit address bus (A0–A18) and 16-bit data bus (DQ0–DQ15), as confirmed in Table 9 of DS25001A and Figure 3 for the TFBGA package.
Does the SST39VF800A-90-4I-B3KE require an external VPP voltage for programming?
No, the SST39VF800A-90-4I-B3KE does not require an external VPP voltage. It integrates an internal charge pump that generates all necessary high-voltage programming signals from the single 2.7–3.6V VDD supply, as explicitly stated in the "Automatic Write Timing" feature and Table 6 (VPP min/max = 0000H).
How many erase sectors and blocks does the SST39VF800A-90-4I-B3KE support?
The SST39VF800A-90-4I-B3KE supports 256 uniform sectors of 2 KWords (4 KB each) and 16 uniform blocks of 32 KWords (64 KB each), as defined in Table 9 (Sector Information y=255, z=16; Block Information y=15, z=256). This structure is fixed and verified via CFI Query data at addresses 2DH–34H.
What is the purpose of the AMS pin designation in the SST39VF800A-90-4I-B3KE datasheet?
In the SST39VF800A-90-4I-B3KE, AMS refers to the Most Significant Address line: AMS = A18 for this 8 Mbit device. As specified in Table 1 and Figure 3, A18 selects the upper half of the 512K-word array during sector/block erase operations, enabling full 8 Mbit addressing without external decoding logic.
Can the SST39VF800A-90-4I-B3KE be used in a 3.3V-only system without level shifters?
Yes, the SST39VF800A-90-4I-B3KE is fully compatible with 3.3V-only systems. Its VDD range is 2.7–3.6V, and all I/Os are CMOS-compatible with VIH = 0.7×VDD and VIL = 0.3×VDD, eliminating need for level shifters when interfaced to standard 3.3V microcontrollers or FPGAs.
