Product details
Overview
SST39WF800A-90-4C-M2QE-T 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-90-4C-M2QE-T datasheet, SST39WF800A-90-4C-M2QE-T pinout, SST39WF800A-90-4C-M2QE-T application, or SST39WF800A-90-4C-M2QE-T equivalent, key selection criteria include its 48-ball WFBGA (5 mm × 6 mm) package, sector/block/chip-erase architecture, toggle-bit/data# polling status detection, and SuperFlash technology's fixed erase/program timing independent of cycle count.
Technical Context
The SST39WF800A-90-4C-M2QE-T implements a split-gate SuperFlash cell with thick-oxide tunneling injector, enabling reliable 1.65–1.95 V write operations without external VPP. Its command-set architecture follows JEDEC-standard pinouts and supports three-byte software ID entry, six-byte erase sequences, and CFI query mode at address 5555H.
Operation relies on CE#, OE#, and WE# control with latched address/data timing: addresses latch on the falling edge of CE# or WE# (whichever occurs last), data latches on the rising edge (whichever occurs first). End-of-write detection uses DQ6 (Toggle Bit) and DQ7 (Data# Polling), both valid after the fourth WE#/CE# pulse for programming and sixth for erase commands.

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), 512K × 16, 90 ns access, no SuperFlash - slower erase (1 s typical chip-erase) | Requires separate 3.0 V rail; unsuitable for 1.8 V-only designs; lacks fixed-timing guarantee | Select only if existing 3.0 V infrastructure exists and endurance beyond 10,000 cycles is not required. |
| S29GL064N90TFIR20 | 3.0 V supply, 4 Mbyte (32 Mbit) density, 90 ns access, mirror-bit architecture, requires VIO pin for 1.8 V I/O | Higher density but incompatible voltage domain; needs level-shifting for 1.8 V host; larger footprint (64-ball BGA) | Choose for capacity expansion where board redesign accommodates 3.0 V supply and larger package. |
Compared with MX29LV800CTTI-90G and S29GL064N90TFIR20, the SST39WF800A-90-4C-M2QE-T uniquely supports 1.8 V-only operation with SuperFlash fixed timing, eliminating software de-rating and reducing system power by removing level shifters or auxiliary regulators.

FAQ
What is the operating voltage range for the SST39WF800A-90-4C-M2QE-T?
The SST39WF800A-90-4C-M2QE-T operates from 1.65 V to 1.95 V, optimized for 1.8 V core logic systems. This single-supply range eliminates the need for external VPP generation or level shifters, and all program/erase functions execute within this window - a key differentiator from 3.0 V flash alternatives. The SST39WF800A-90-4C-M2QE-T maintains full specification compliance across this range, including 90 ns read access and 28 µs word-program timing.
Does the SST39WF800A-90-4C-M2QE-T support JEDEC-standard commands and pinouts?
Yes, the SST39WF800A-90-4C-M2QE-T conforms fully to JEDEC standard pin assignments and command sets for x16 asynchronous flash memory. It supports standard read, word-program, sector-erase, block-erase, and chip-erase sequences, plus Software ID Entry (90H), CFI Query (98H), and Software ID Exit (F0H) commands. The SST39WF800A-90-4C-M2QE-T pinout matches industry-standard 48-ball WFBGA layouts, enabling drop-in compatibility with other JEDEC-compliant x16 flash devices in the same package footprint.
How does the SST39WF800A-90-4C-M2QE-T detect completion of program or erase operations?
The SST39WF800A-90-4C-M2QE-T provides two hardware-supported status detection methods: Toggle Bit (DQ6) toggles between 0 and 1 during internal operations and stops when complete; Data# Polling (DQ7) returns complemented data during programming and true data upon completion. Both are valid after the fourth WE#/CE# pulse for programming and sixth pulse for erase commands. The SST39WF800A-90-4C-M2QE-T requires no external polling delay - these signals enable deterministic, cycle-accurate host synchronization without fixed timeout loops.
What package type is used for the SST39WF800A-90-4C-M2QE-T?
The SST39WF800A-90-4C-M2QE-T uses a 48-ball WFBGA (Wafer-Level Fine-Pitch Ball Grid Array) package measuring 5 mm × 6 mm, with 0.5 mm ball pitch. This micro-package supports high-density PCB layouts and meets RoHS requirements with lead-free terminations. Pin assignments match Figure 2 in the official datasheet, including dedicated VSS balls and NC positions for A1, A2, A5, A9, A10, A13–A16, DQ1–DQ4, and DQ11 - all of which must remain unconnected in layout.
What is the endurance and data retention specification for the SST39WF800A-90-4C-M2QE-T?
The SST39WF800A-90-4C-M2QE-T is rated for 100,000 program/erase cycles minimum and greater than 100 years of data retention at 25°C. These values are guaranteed per JEDEC standards A117 (endurance) and A103 (retention), validated across temperature ranges from -40°C to +85°C. Unlike conventional flash, SuperFlash technology maintains fixed erase/program timing across all cycles - meaning the SST39WF800A-90-4C-M2QE-T requires no software derating or increased timeout margins as endurance accumulates.
