Product details
Overview
SST39WF800A-90-4I-M2QE from Silicon Storage Technology is an 8 Mbit (512K × 16) single-supply Multi-Purpose Flash memory IC with 90 ns read access time, 1.65–1.95 V operation, and JEDEC-standard x16 asynchronous interface. It delivers 100,000 program/erase cycles endurance and >100-year data retention, used for firmware storage and configuration in embedded controllers and industrial HMI systems.
For engineers reviewing the SST39WF800A-90-4I-M2QE datasheet, SST39WF800A-90-4I-M2QE pinout, SST39WF800A-90-4I-M2QE application, or SST39WF800A-90-4I-M2QE equivalent, key selection criteria include its 48-ball WFBGA (5 mm × 6 mm) package, sector/block/chip-erase flexibility, SuperFlash low-energy programming, and hardware/software data protection compliance with JEDEC flash standards.
Technical Context
The SST39WF800A-90-4I-M2QE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed 28 µs word-program and 36 ms sector/block-erase times independent of cycle count. Its command-set architecture uses standard microprocessor write sequences with CE#/WE#/OE# control logic and latched address/data buses.
End-of-write detection relies on dual software methods: Data# Polling (DQ7) and Toggle Bit (DQ6), both valid after the fourth WE# or CE# pulse for programming and sixth pulse for erase operations. The device supports CFI Query mode (entry via 5555H/2AAAH/5555H + 98H) and Software ID mode (90H) for automated system identification and compatibility verification.

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), 56-pin TSOP package, slower 90 ns read but higher 100 mA program current | Requires level-shifting in 1.8 V systems; larger footprint; lacks SuperFlash low-energy advantage | Select only if legacy 3 V infrastructure exists and board space permits TSOP mounting |
| S29GL064N90TFI010 | 3 V supply, 64 Mbit density, 56-ball BGA, supports burst reads and write buffering | Over-specified capacity and features for 8 Mbit use cases; incompatible voltage domain and command set | Consider only for future-proofing where scalable density and enhanced performance justify redesign cost |
Compared with MX29LV800CTTI-90G and S29GL064N90TFI010, the SST39WF800A-90-4I-M2QE provides unique 1.8 V native operation, lower active/standby power, and fixed-timing SuperFlash architecture-making it optimal for space-constrained, battery-sensitive, or thermally limited embedded designs requiring precise firmware update control.

FAQ
What is the operating voltage range for the SST39WF800A-90-4I-M2QE?
The SST39WF800A-90-4I-M2QE operates exclusively within a 1.65 V to 1.95 V supply range, optimized for 1.8 V nominal systems. This single-supply design eliminates the need for external VPP generation or level shifters. Operation outside this range-such as at 3.3 V or below 1.65 V-will not function and may cause permanent damage, as confirmed by absolute maximum ratings and DC operating characteristics in the official datasheet.
Does the SST39WF800A-90-4I-M2QE support JEDEC-standard commands and pinouts?
Yes, the SST39WF800A-90-4I-M2QE fully conforms to JEDEC Standard JESD21-C for x16 flash memories, including pin assignments, command sets (e.g., Word-Program, Sector-Erase), and Common Flash Interface (CFI) query structure. Its CFI data at addresses 10H–12H returns "QRY", and Software ID Entry (90H) yields Manufacturer ID 00BFH and Device ID 273FH-verifying JEDEC interoperability with standard flash controllers.
How does the SST39WF800A-90-4I-M2QE handle write completion detection?
The SST39WF800A-90-4I-M2QE provides two simultaneous, software-controlled methods: Data# Polling (DQ7 toggles complement-to-data until completion, then returns true data) and Toggle Bit (DQ6 alternates 0/1 during operation, then locks). Both are valid after the fourth WE#/CE# pulse for programming and sixth pulse for erase-enabling host firmware to poll without timeouts or interrupts, as detailed in Figures 7–8 and Table 4 of the datasheet.
What package type is used for the SST39WF800A-90-4I-M2QE?
The SST39WF800A-90-4I-M2QE uses a 48-ball WFBGA (5 mm × 6 mm) package, designated in the part number suffix "M2QE". Pin assignments match Figure 2 of the datasheet, with dedicated VSS balls and NC positions clearly defined. This micro-package supports fine-pitch PCB assembly and meets RoHS lead-free requirements, distinguishing it from the TFBGA and XFLGA variants offered in the same family.
Is the SST39WF800A-90-4I-M2QE suitable for automotive applications?
The SST39WF800A-90-4I-M2QE is rated for industrial temperature range (–40°C to +85°C) and qualified per JEDEC reliability standards (A117 endurance, A103 retention), making it suitable for under-hood automotive infotainment and body-control modules. However, it is not AEC-Q100 certified; for full automotive qualification, designers should verify with Microchip's post-acquisition documentation or consider pin-compatible AEC-Q100 qualified derivatives.
