Product details
Overview
SST39WF800B-70-4I-B3KE-T from Microchip Technology (formerly Silicon Storage Technology) is an 8 Mbit (512K × 16) parallel flash memory IC using SuperFlash® technology, operating at 1.65–1.95 V, with 70 ns read access time, 14 μs/word program speed, and industrial temperature range (−40°C to +85°C). It is used in embedded boot code storage for WiFi modules and digital media players.
For engineers reviewing the SST39WF800B-70-4I-B3KE-T datasheet, SST39WF800B-70-4I-B3KE-T pinout, SST39WF800B-70-4I-B3KE-T application, or SST39WF800B-70-4I-B3KE-T equivalent, key selection criteria include 1.8V operation, WFBGA-48 (4 mm × 6 mm) package compatibility, sector/block erase flexibility, and MPF+ features including erase suspend and hardware reset.
Technical Context
This device belongs to the MPF+ family and implements a parallel asynchronous interface with x16 data bus width. Its SuperFlash® cell architecture enables single-transistor storage with high endurance (100,000 cycles) and 100-year data retention, eliminating need for charge pumps during erase/program.
The SST39WF800B-70-4I-B3KE-T supports uniform 2 Kword and 32 Kword erase sectors, chip erase in 70 ms (typ), and includes hardware reset and erase suspend-features distinguishing MPF+ from base MPF devices and enabling robust in-system firmware updates.

FAQ
What voltage range does the SST39WF800B-70-4I-B3KE-T support?
The SST39WF800B-70-4I-B3KE-T operates strictly within 1.65 V to 1.95 V. It is not rated for 3V or 5V operation. This 1.8V nominal range enables direct interface with low-power microcontrollers and SoCs without external level translation, reducing BOM cost and board area. The SST39WF800B-70-4I-B3KE-T's voltage tolerance is validated per its official datasheet DS01360A.
Is the SST39WF800B-70-4I-B3KE-T pin-compatible with SST39WF800C-70-4I-B3KE-T?
Yes, the SST39WF800B-70-4I-B3KE-T and SST39WF800C-70-4I-B3KE-T share identical pinout, package (48-ball WFBGA), and electrical interface. However, the SST39WF800B-70-4I-B3KE-T includes MPF+ features-erase suspend and hardware reset-that are absent in the 'C' variant. Functionally, they are drop-in replacements only if those features are unused.
What erase options does the SST39WF800B-70-4I-B3KE-T support?
The SST39WF800B-70-4I-B3KE-T supports three erase modes: 2 Kword sector erase (18 ms typ), 32 Kword block erase (18 ms typ), and full chip erase (70 ms typ). All erase operations are uniform and predictable, enabling deterministic firmware update timing. The SST39WF800B-70-4I-B3KE-T also supports erase suspend, allowing interruption of erase to service urgent read requests.
Does the SST39WF800B-70-4I-B3KE-T require special programming voltage or charge pumps?
No, the SST39WF800B-70-4I-B3KE-T uses SuperFlash® technology, which eliminates on-chip charge pumps. All program and erase operations execute using only the core 1.8V supply. This simplifies power design, improves reliability, and reduces EMI compared to conventional flash requiring high-voltage generation. The SST39WF800B-70-4I-B3KE-T achieves 14 μs/word program speed under this single-supply architecture.
What is the industrial temperature rating for SST39WF800B-70-4I-B3KE-T?
The SST39WF800B-70-4I-B3KE-T is rated for −40°C to +85°C operation, meeting industrial-grade environmental requirements. This specification applies to the full functional range-including read, program, and erase-with guaranteed timing and endurance. The SST39WF800B-70-4I-B3KE-T's qualification includes thermal cycling and high-temperature operating life testing per JEDEC standards.
