Product details
Overview
SST39VF3202-70-4I-B3KE-T from Microchip Technology is a 32 Mbit (2M × 16) Multi-Purpose Flash Plus (MPF+) memory IC with x16 asynchronous interface, 70 ns read access time, single 2.7–3.6 V supply operation, and top-block hardware write protection. It implements SuperFlash technology for high reliability in embedded firmware storage applications requiring field-upgradable code or configuration data.
For engineers reviewing the SST39VF3202-70-4I-B3KE-T datasheet, SST39VF3202-70-4I-B3KE-T pinout, SST39VF3202-70-4I-B3KE-T application, or SST39VF3202-70-4I-B3KE-T equivalent, key selection considerations include its 2M×16 organization, TSOP-48/TBGA-48 packaging options, JEDEC-standard command set, erase-suspend capability, and top 32 KWord boot block protection - all critical for legacy industrial controller and telecom baseband design reuse.
Technical Context
The SST39VF3202-70-4I-B3KE-T uses SST's proprietary split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed 7 µs word-program and 18 ms sector/block-erase times independent of endurance cycling. Its control logic supports standard microprocessor bus timing with CE#/OE#/WE# strobes and latched address/data paths.
Hardware features include dedicated WP# for top-boot-block protection, RST# for hardware reset to read mode, and dual status detection via DQ6 toggle bit and DQ7 data# polling. It implements JEDEC-standard flash command sets including sector/block/chip erase, erase-suspend/resume, and CFI query mode for automatic system identification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF3201B | Same density and interface, but bottom-block protection instead of top-block; 90 ns access time vs. 70 ns | Requires PCB-level address decoding change to support bottom-boot architecture | Select when legacy designs use bottom-boot layout or require longer data retention margin at cost of speed |
| MX29LV320ETTI-70G | 32 Mbit x16, 70 ns, but uses standard NOR architecture with variable erase times and no erase-suspend | Lacks real-time suspend capability; requires full erase before partial update | Choose only if SuperFlash-specific features are unnecessary and second-source availability is prioritized |
Compared with SST39VF3201B and MX29LV320ETTI-70G, the SST39VF3202-70-4I-B3KE-T delivers deterministic 70 ns read timing, top-boot hardware protection aligned with common bootloader placement, and erase-suspend for zero-downtime field updates - making it uniquely suited for safety-critical or high-availability embedded systems where reliability and update flexibility are non-negotiable.

FAQ
What is the memory organization of the SST39VF3202-70-4I-B3KE-T?
The SST39VF3202-70-4I-B3KE-T is organized as 2M × 16, delivering 32 Mbit (4 MB) of x16 asynchronous flash memory. Its address space spans A0–A20, with A20 used for block erase addressing. This configuration supports direct connection to 16-bit microprocessor buses without data multiplexing or glue logic, and is validated in the SST39VF3202-70-4I-B3KE-T datasheet DS25028A section 2.
Does the SST39VF3202-70-4I-B3KE-T support hardware write protection?
Yes, the SST39VF3202-70-4I-B3KE-T implements top-block hardware write protection via the WP# pin. When WP# is driven low, the top 32 KWord (64 KB) region - address range 1F8000H–1FFFFFH - is locked against program and erase operations. This protects bootloader code from corruption during field updates, as confirmed in Table 3 and section 9 of the SST39VF3202-70-4I-B3KE-T datasheet DS25028A.
What package type does the SST39VF3202-70-4I-B3KE-T use?
The SST39VF3202-70-4I-B3KE-T uses a 48-ball TFBGA package with B3K footprint (6 mm × 8 mm), as specified in Figure 3 of the SST39VF3202-70-4I-B3KE-T datasheet DS25028A. It is pin-compatible with the 48-lead TSOP variant (12 mm × 20 mm), enabling layout reuse across form factors without functional change.
How does the SST39VF3202-70-4I-B3KE-T indicate completion of a program or erase operation?
The SST39VF3202-70-4I-B3KE-T provides two software-detectable status mechanisms: Data# Polling on DQ7 and Toggle Bit on DQ6. During internal operations, DQ7 outputs complemented data (program) or '0' (erase), reverting to true data or '1' upon completion; DQ6 toggles between 0 and 1 until completion, then stabilizes. These are defined in Table 2 and section 7 of the SST39VF3202-70-4I-B3KE-T datasheet DS25028A.
Is the SST39VF3202-70-4I-B3KE-T recommended for new designs?
No, the SST39VF3202-70-4I-B3KE-T is marked "Not Recommended for New Designs" per the official Microchip datasheet DS25028A (page 1). Microchip recommends migrating to SST39VF3201B for new projects. However, SST39VF3202-70-4I-B3KE-T remains supported for existing designs requiring continuity, with full documentation and supply chain availability maintained by Aetrix Electronics.
