Product details
Overview
SST39WF1601-90-4C-B3KE-T from Silicon Storage Technology is a 16 Mbit (1M × 16) Multi-Purpose Flash Plus (MPF+) memory IC operating at 1.65–1.95 V, featuring 90 ns read access time, bottom-block hardware write protection (protects 000000H–007FFFH), and JEDEC-standard x16 asynchronous interface. It serves as nonvolatile program/data storage in embedded boot code, firmware update, and configuration memory applications.
For engineers reviewing the SST39WF1601-90-4C-B3KE-T datasheet, SST39WF1601-90-4C-B3KE-T pinout, SST39WF1601-90-4C-B3KE-T application, or SST39WF1601-90-4C-B3KE-T equivalent, key selection criteria include its 1.65–1.95 V single-supply operation, bottom-boot block protection scheme, 100,000-cycle endurance, 100-year data retention, and 48-ball WFBGA (4 mm × 6 mm) package compatibility with space-constrained industrial controllers and IoT edge devices.
Technical Context
The SST39WF1601-90-4C-B3KE-T implements SuperFlash split-gate technology for fixed erase/program timing independent of cycle count, eliminating software de-rating. Its command-set architecture supports JEDEC-standard CFI query, sector/block/chip erase, erase-suspend/resume, and Security ID (128-bit factory + 128-bit user).
It uses latched address/data with CMOS I/O compatibility, operates in Read, Word-Program, Sector-Erase (2 KWord), Block-Erase (32 KWord), and Chip-Erase modes, and integrates hardware reset (RST#), write protect (WP#), and auto low-power mode (5 µA standby). The device enters Auto Low Power after valid read access and exits on any address/control transition-no access penalty.
Key Specifications

Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus; A0–A11 select sector during erase, A0–A15 select block. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; tri-stated when CE# or OE# high; latched on WE#/CE# edges. |
| CE# | Chip Enable | Active-low device select; disables outputs and reduces current to 40 µA in standby. |
| OE# | Output Enable | Active-low output gating; controls data bus drive without affecting internal state. |
| WE# | Write Enable | Controls latching of address/data during program/erase; initiates internal timing sequences. |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block; prevents erase/program when grounded. |
| RST# | Reset | Hardware abort of in-progress erase/program; forces immediate return to read mode. |
| VDD | Power Supply | 1.65–1.95 V core supply; internally generates VPP for programming-no external high-voltage source needed. |
| VSS | Ground | Reference for all I/O and core logic; two dedicated VSS balls ensure stable low-impedance return path. |
| NC | No Connection | Unbonded pins (e.g., ball E1, G1); must be left floating or tied to VSS per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Fixed 28 µs word-program and 36 ms sector/block-erase times across full lifetime-no software adaptation required. |
| Erase-Suspend/Resume | Allows real-time read access to non-suspended sectors during background erase-critical for fail-safe firmware updates. |
| Security ID Space | 256-bit secure identifier (128-bit factory + 128-bit user); programmable and lockable to prevent cloning or unauthorized reprogramming. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid access-cuts dynamic power by >99% in polling-based status detection. |
| JEDEC CFI Compliance | Supports both SST-specific and general CFI query modes for automatic driver detection and cross-manufacturer firmware portability. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160ETTI-90G | 3.0 V supply (2.7–3.6 V), 16 Mbit x16, top-boot configuration, no Security ID or erase-suspend. | Requires separate 3.0 V rail; lacks suspend/resume and secure ID-unsuitable for secure OTA updates. | Select only if legacy 3.0 V system design prohibits voltage translation and boot-block location matches (top vs. bottom). |
| S29GL032N90TFI020 | 3.0 V supply, 32 Mbit x16, bottom-boot, no Auto Low Power mode, 128-bit Security ID only. | Higher density but incompatible voltage; higher active current (15 mA typical) increases thermal budget in compact modules. | Consider only when 32 Mbit capacity is mandatory and system can accommodate 3.0 V supply and higher power dissipation. |
Compared with MX29LV160ETTI-90G and S29GL032N90TFI020, the SST39WF1601-90-4C-B3KE-T uniquely delivers 1.65–1.95 V operation, bottom-boot hardware protection, erase-suspend, and dual 128-bit Security ID-all in a 4 mm × 6 mm WFBGA, enabling smaller, cooler, and more secure embedded designs.

FAQ
What is the exact memory organization and density of the SST39WF1601-90-4C-B3KE-T?
The SST39WF1601-90-4C-B3KE-T is organized as 1,048,576 words × 16 bits (1M × 16), totaling 16 Mbit (2 MByte) of nonvolatile storage. This configuration supports byte-wide or word-wide addressing in x16 systems and maps directly to common microcontroller memory buses without glue logic. Its uniform 2 KWord sector and 32 KWord block architecture enables efficient firmware partitioning and incremental updates.
Does the SST39WF1601-90-4C-B3KE-T support hardware write protection, and how is it configured?
Yes, the SST39WF1601-90-4C-B3KE-T implements bottom-block hardware write protection via the WP# pin. When WP# is driven low, the bottom 32 KWord block (addresses 000000H–007FFFH) is locked against program and erase operations-ideal for safeguarding boot code. If WP# is left floating, an internal pull-up holds it high, disabling protection. This differs from the SST39WF1602, which protects the top 32 KWord block instead.
What are the supported erase capabilities of the SST39WF1601-90-4C-B3KE-T?
The SST39WF1601-90-4C-B3KE-T supports three erase granularities: sector-erase (2 KWord), block-erase (32 KWord), and chip-erase (entire 16 Mbit array). Sector-erase completes in 36 ms (typical), block-erase in 36 ms (typical), and chip-erase in 140 ms (typical). All erase operations use JEDEC-standard command sequences and support Data# Polling (DQ7) and Toggle Bit (DQ6/DQ2) status detection.
How does the Auto Low Power mode function in the SST39WF1601-90-4C-B3KE-T?
The SST39WF1601-90-4C-B3KE-T enters Auto Low Power mode automatically after a valid read access, reducing active current from ~9 mA to 5 µA. It exits instantly on any address or control signal transition (e.g., CE#, OE#, or A0–A19 change) with zero access time penalty. This feature significantly lowers average power in polling-based systems-such as those monitoring DQ6 toggle during erase-without requiring software intervention.
Is the SST39WF1601-90-4C-B3KE-T compatible with JEDEC-standard flash interfaces?
Yes, the SST39WF1601-90-4C-B3KE-T conforms fully to JEDEC Standard JESD21-C for x16 flash pin assignments and command sets. It supports both SST-specific and general Common Flash Interface (CFI) query modes, enabling automatic driver detection in Linux MTD and U-Boot environments. Its command sequences-including Word-Program, Sector-Erase, and Chip-Erase-are JEDEC-compliant and interoperable with standard flash abstraction layers.
