Product details
Overview
SST39WF1601-70-4C-MAQE-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 in space-constrained, low-voltage systems. It operates from 1.65–1.95 V, delivers 70 ns read access time, supports bottom 32 KWord hardware block protection, and features uniform 2 KWord sector and 32 KWord block erase architecture.
For engineers reviewing the SST39WF1601-70-4C-MAQE-T datasheet, SST39WF1601-70-4C-MAQE-T pinout, SST39WF1601-70-4C-MAQE-T application, or SST39WF1601-70-4C-MAQE-T equivalent, key selection considerations include its 1.65–1.95 V single-supply operation, JEDEC-compliant x16 asynchronous interface, bottom-boot block protection scheme, 100,000-cycle endurance, and 48-ball WFBGA (4 mm × 6 mm) package with RST# and WP# pins.
Technical Context
The SST39WF1601-70-4C-MAQE-T implements SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its command set conforms to JEDEC standard pin assignments and includes full software data protection (SDP) requiring three-byte sequences for program and six-byte sequences for erase operations.
It supports Erase-Suspend/Erase-Resume functionality via B0H/30H commands, provides dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits), and integrates CFI Query mode for device identification and geometry reporting. The device uses latched address/data and internal VPP generation, eliminating external high-voltage requirements.

FAQ
What is the exact memory organization of the SST39WF1601-70-4C-MAQE-T?
The SST39WF1601-70-4C-MAQE-T is organized as 1M × 16, delivering 16 Mbit (2 MB) total capacity with true x16 data bus width. Its address space spans A0–A19 (20 bits), and it implements bottom-boot architecture with protected region 000000H–007FFFH. This structure is confirmed in the official Microchip datasheet DS-20005014B section "Product Description" and Table 3.
Does the SST39WF1601-70-4C-MAQE-T support JEDEC-standard command sets?
Yes, the SST39WF1601-70-4C-MAQE-T fully conforms to JEDEC standard pin assignments and command definitions for x16 flash memories. It supports both SST-specific and general Common Flash Interface (CFI) Query modes, enabling interoperability with standard flash drivers. This compliance is explicitly stated in the "JEDEC Standard" feature bullet and Table 6 of the DS-20005014B datasheet.
How does hardware block protection work on the SST39WF1601-70-4C-MAQE-T?
The SST39WF1601-70-4C-MAQE-T implements bottom-block hardware protection: when WP# is driven low, the bottom 32 KWord (128 KB) region (addresses 000000H–007FFFH) is locked against program and erase operations. This differs from the SST39WF1602, which protects the top block. The behavior is documented in the "Hardware Block Protection" section and Table 3 of DS-20005014B.
What are the supported erase granularities for the SST39WF1601-70-4C-MAQE-T?
The SST39WF1601-70-4C-MAQE-T supports three erase modes: sector-erase (2 KWord = 4 KB), block-erase (32 KWord = 64 KB), and chip-erase (full 16 Mbit array). All erase times are fixed at 36 ms (sector/block) and 140 ms (chip), independent of wear level-enabled by SuperFlash technology. These values are specified in the "Features" section and Table 11 of DS-20005014B.
Is the SST39WF1601-70-4C-MAQE-T qualified for automotive applications?
The SST39WF1601-70-4C-MAQE-T is offered in AEC-Q100-qualified variants, meeting stress test requirements for automotive use. While the base part number denotes commercial/industrial grade, Microchip provides automotive-grade versions (e.g., with -10°C to +85°C or -40°C to +125°C temp ranges) under related suffixes. Qualification status and part numbering conventions are detailed in the "AEC-Q100-qualified devices available" footnote of DS-20005014B.
