Product details
Overview
SST39WF1602-70-4I-B3KE from Microchip Technology (formerly Silicon Storage Technology) is a 16 Mbit (1M × 16) Multi-Purpose Flash Plus (MPF+) memory IC designed for embedded program and configuration storage in low-voltage systems. It operates from a single 1.65–1.95 V supply, delivers 70 ns read access time, supports hardware top-block protection (32 KWord), and features JEDEC-standard x16 asynchronous interface for microcontroller and SoC boot code storage.
For engineers reviewing the SST39WF1602-70-4I-B3KE datasheet, SST39WF1602-70-4I-B3KE pinout, SST39WF1602-70-4I-B3KE application, or SST39WF1602-70-4I-B3KE equivalent, this page provides verified technical context, JEDEC-compliant pin mapping, real-world use cases in industrial firmware storage, and validated alternative flash devices with documented functional and protection-mode differences.
Technical Context
The SST39WF1602-70-4I-B3KE implements SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program timing independent of cycle count. It uses standard JEDEC x16 command sets and supports CFI Query modes (SST and general) for host compatibility.
Its architecture includes latched address/data buses, hardware reset (RST#), write protect (WP#) for top 32 KWord block, and dual status detection via DQ7 (Data# Polling) and DQ6/DQ2 (Toggle Bits). Erase-suspend/resume capability allows concurrent read/program during active erase operations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1602-70-4I-B3KE | Same density and pinout, but uses older SST39VF process; 3.0 V operation (2.7–3.6 V), slower 90 ns access, no Auto Low Power mode. | Lacks low-voltage compatibility and power optimization; unsuitable for 1.8 V systems or battery-powered designs. | Select only if legacy 3 V design requires identical footprint and JEDEC command set without voltage scaling. |
| MX29LV160ETTI-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V; supports CFI but lacks Erase-Suspend, Security ID, and top-block WP#; different command sequence for sector erase. | No hardware suspend capability limits real-time update flexibility; no factory-programmed security ID for anti-cloning. | Choose when cost is primary constraint and system does not require suspend/resume or secure binding features. |
Compared with SST39VF1602-70-4I-B3KE and MX29LV160ETTI-70G, the SST39WF1602-70-4I-B3KE uniquely combines 1.8 V operation, fixed-timing SuperFlash, top-block hardware protection, and Erase-Suspend-making it optimal for next-generation low-power, safety-aware embedded systems where voltage scaling and update resilience are mandatory.

FAQ
What is the exact memory organization of the SST39WF1602-70-4I-B3KE?
The SST39WF1602-70-4I-B3KE is organized as 1,048,576 words × 16 bits (1M × 16), totaling 16 Mbit. Its address space spans 000000H to 0FFFFFH, with top 32 KWord (0F8000H–0FFFFFH) protected by hardware when WP# is asserted. This structure aligns with JEDEC-standard x16 flash addressing and supports direct mapping to 32-bit MCU buses via word-aligned access.
Does the SST39WF1602-70-4I-B3KE require an external VPP voltage for programming?
No, the SST39WF1602-70-4I-B3KE does not require external VPP. It generates all necessary high-voltage programming pulses internally using its on-chip charge pump, operating solely from the 1.65–1.95 V VDD supply. This eliminates external high-voltage circuitry, simplifies PCB design, and enhances system-level reliability compared to legacy flash devices requiring 12 V VPP.
How does hardware block protection work on the SST39WF1602-70-4I-B3KE?
Hardware block protection on the SST39WF1602-70-4I-B3KE is implemented via the WP# pin: when pulled low, it permanently locks the top 32 KWord block (0F8000H–0FFFFFH) against all erase and program operations. Unlike software-only schemes, this protection remains active even during power transitions and cannot be overridden by command sequences-ensuring bootloader integrity in mission-critical systems.
Can the SST39WF1602-70-4I-B3KE be used in automotive applications?
Yes-the SST39WF1602-70-4I-B3KE is available in AEC-Q100-qualified versions (e.g., SST39WF1602-70-4I-B3KE with automotive temp grade -40°C to +85°C). Its 100-year data retention, 100,000-cycle endurance, and hardware reset (RST#) make it suitable for infotainment boot memory, ADAS configuration storage, and telematics firmware-provided the specific part number carries the automotive qualification suffix.
What status detection methods does the SST39WF1602-70-4I-B3KE support during write operations?
The SST39WF1602-70-4I-B3KE supports two hardware status detection methods: Data# Polling (DQ7 toggles complement until completion, then returns true data) and Toggle Bits (DQ6 toggles during operation, stops when complete). Both are accessible during active erase/program and require no additional pins-enabling efficient polling-based firmware drivers without interrupt dependency.
