Product details
Overview
SST39WF1601-70-4I-B3KE-T 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. It operates from a single 1.65–1.95 V supply, delivers 70 ns read access time, supports bottom-block hardware write protection (000000H–007FFFH), and features sector/block/chip erase with erase-suspend/resume capability.
For engineers reviewing the SST39WF1601-70-4I-B3KE-T datasheet, SST39WF1601-70-4I-B3KE-T pinout, SST39WF1601-70-4I-B3KE-T application, or SST39WF1601-70-4I-B3KE-T equivalent, key selection considerations include its 48-ball WFBGA (4 mm × 6 mm) package, JEDEC-compliant x16 asynchronous interface, SuperFlash technology-based reliability (100,000 program/erase cycles, >100 years data retention), and support for CFI query and Security ID functions.
Technical Context
This device implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count-eliminating software de-rating required by conventional flash. Its command set follows JEDEC-standard pin assignments and supports both SST-specific and general Common Flash Interface (CFI) query modes for system compatibility.
Hardware block protection is implemented via the WP# pin to safeguard the bottom 32 KWord boot block; RST# provides hardware reset to Read mode; and dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits) enables robust end-of-write verification without external timing dependencies.

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-T | 3.0 V operation (2.7–3.6 V), same 1M×16 organization and WFBGA package; lacks Auto Low Power mode and Security ID | Requires separate 3.0 V rail; unsuitable where 1.8 V core voltage mandates single-supply design | Select only if legacy 3.0 V system architecture prohibits voltage translation |
| MX29LV160DBTI-70G | 3.0 V operation, 1M×16, 48-ball TSOP, no CFI or Security ID; endurance 100K cycles but retention rated at 20 years | TSOP package increases board area vs. WFBGA; no erase-suspend or CFI reduces firmware portability | Consider only for cost-sensitive, non-automotive applications where footprint and advanced features are secondary |
Compared with SST39VF1601C-70-4I-B3KE-T and MX29LV160DBTI-70G, the SST39WF1601-70-4I-B3KE-T uniquely combines 1.8 V operation, WFBGA packaging, CFI compliance, Security ID, and erase-suspend - making it the only choice for space-constrained, safety-aware, and field-upgradable embedded systems requiring long-term data integrity.

FAQ
What is the exact memory organization and density of the SST39WF1601-70-4I-B3KE-T?
The SST39WF1601-70-4I-B3KE-T is organized as 1M × 16, delivering 16 Mbit (2 MByte) of total storage. Its x16 data bus supports parallel access, and the address range spans A0–A19, with AMS = A19 for sector/block selection. This configuration is optimized for microcontrollers and SoCs with 16-bit external memory buses.
Does the SST39WF1601-70-4I-B3KE-T support hardware write protection, and how is it configured?
Yes, the SST39WF1601-70-4I-B3KE-T implements bottom-block hardware write protection via the WP# pin. When WP# is driven low, the bottom 32 KWord (000000H–007FFFH) boot block is protected from program and erase operations. If WP# is left floating, an internal pull-up holds it high, disabling protection. This differs from SST39WF1602, which protects the top block.
How does the SST39WF1601-70-4I-B3KE-T indicate completion of program or erase operations?
The SST39WF1601-70-4I-B3KE-T provides two hardware-supported status detection methods: Data# Polling on DQ7 (complement during operation, true data upon completion) and Toggle Bit on DQ6 (toggles between 0/1 during operation, stops toggling when complete). Both are valid after the rising edge of the fourth (program) or sixth (erase) WE# pulse.
What package type and dimensions does the SST39WF1601-70-4I-B3KE-T use?
The SST39WF1601-70-4I-B3KE-T uses a 48-ball WFBGA package measuring 4 mm × 6 mm with 0.5 mm ball pitch. This ultra-compact, RoHS-compliant package is optimized for high-density PCB layouts and supports reflow soldering per J-STD-020 standards. Pin assignments match JEDEC-standard x16 flash footprints.
Is the SST39WF1601-70-4I-B3KE-T qualified for automotive applications?
The base SST39WF1601-70-4I-B3KE-T is rated for industrial temperature (–40°C to +85°C) and is RoHS compliant. An AEC-Q100-qualified variant is available (e.g., SST39WF1601-70-4I-B3KE-T with automotive screening), meeting stress testing requirements for automotive ECUs. Always verify the specific part number's qualification status with Microchip's official documentation.
