Product details
Overview
SST39VF1602-70-4I-B3KE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with JEDEC-standard x16 asynchronous interface, 70 ns read access time, top 32 KWord hardware block protection, and single 2.7–3.6V supply operation. It supports sector/block/chip erase, Word-Program (7 µs typical), erase-suspend/resume, and Security-ID for embedded firmware storage in industrial control and legacy communication systems.
For engineers reviewing the SST39VF1602-70-4I-B3KE datasheet, SST39VF1602-70-4I-B3KE pinout, SST39VF1602-70-4I-B3KE application, or SST39VF1602-70-4I-B3KE equivalent, key selection criteria include boot-block protection direction (top vs. bottom), TSOP-48 vs. TFBGA-48 package compatibility, 70 ns timing grade, industrial temperature range (–40°C to +85°C), and SuperFlash endurance (100,000 cycles).
Technical Context
The SST39VF1602-70-4I-B3KE implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its command-set architecture conforms to JEDEC standard flash pinouts and includes six-byte sequences for block erase (50H) and chip erase (10H), plus three-byte sequences for word-program and security ID access.
Hardware data protection combines WP#-controlled top-boot-block lock (0F8000H–0FFFFFH), RST#-driven hardware reset, and noise/glitch immunity (<5 ns pulse rejection). Status detection uses DQ7 Data# Polling and dual-toggle bits (DQ6/DQ2) for real-time program/erase monitoring without CPU polling overhead.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C-70-4I-B3KE | Bottom 32 KWord block protection (000000H–007FFFH); same density, timing, and package | Requires firmware partitioning in lower address space; incompatible with top-boot architectures | Select only if boot code resides in lowest 32 KWord and legacy board layout uses bottom-protection scheme |
| MX29LV160ETTI-70G | 16 Mbit x16, 70 ns, but uses different command set (Spansion/AMD) and lacks Security-ID and CFI query support | No hardware suspend/resume; requires modified driver stack; no factory-programmed ID segment | Use only when migrating from AMD-family designs and Security-ID is not required |
Compared with SST39VF1601C-70-4I-B3KE, the SST39VF1602-70-4I-B3KE provides top-boot protection essential for modern bootloaders, while MX29LV160ETTI-70G offers pin-compatible replacement only for non-security-critical applications lacking suspend/resume or CFI features.

FAQ
What does the "B3KE" suffix indicate in SST39VF1602-70-4I-B3KE?
The "B3KE" suffix identifies the 48-ball TFBGA package with 6 mm × 8 mm footprint (B3K) and industrial temperature range (–40°C to +85°C, denoted by "E"). It confirms RoHS compliance and distinguishes this variant from TSOP-48 versions (e.g., "B3K" without "E" would be commercial grade). The SST39VF1602-70-4I-B3KE uses the same SuperFlash core and command set as other members of the SST39VF160x family.
Does SST39VF1602-70-4I-B3KE support both sector and block erase operations?
Yes, the SST39VF1602-70-4I-B3KE supports uniform 2 KWord sector erase and uniform 32 KWord block erase via JEDEC-compliant six-byte command sequences (30H for sector, 50H for block). Each operation is verified using DQ7 Data# Polling or DQ6 Toggle Bit status detection. Sector erase targets AMS–A11 address lines; block erase uses AMS–A15, where AMS = A19 for the SST39VF1602-70-4I-B3KE.
How is hardware block protection implemented on SST39VF1602-70-4I-B3KE?
The SST39VF1602-70-4I-B3KE implements top 32 KWord hardware block protection (0F8000H–0FFFFFH) via the WP# pin: when grounded, it disables all program and erase operations in that region. If left floating, an internal pull-up holds WP# high, disabling protection. This differs from SST39VF1601 variants, which protect the bottom 32 KWord block - a critical distinction when selecting the correct part for existing board layouts.
Can SST39VF1602-70-4I-B3KE be used in new designs despite "Not Recommended for New Designs" status?
While Microchip labels SST39VF1602-70-4I-B3KE as "Not Recommended for New Designs" in favor of newer MPF+ variants (e.g., SST39VF1601C), it remains fully supported for legacy design refresh, repair, and long-lifecycle industrial programs. Aetrix Electronics maintains active inventory and supply chain continuity for SST39VF1602-70-4I-B3KE, including traceable sourcing and lifecycle coordination.
What is the function of the RST# pin on SST39VF1602-70-4I-B3KE?
The RST# pin on SST39VF1602-70-4I-B3KE provides hardware-initiated abort of in-progress erase or program operations and forces immediate return to read mode. When held low for ≥TRP (typically 100 ns), it terminates active writes; after release, a minimum TRHR delay (typically 100 ns) is required before valid reads resume. This ensures deterministic recovery during power faults or watchdog timeouts in safety-critical systems using SST39VF1602-70-4I-B3KE.
