Product details
Overview
SST39WF1601-90-4I-MBQE-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 is used in embedded systems for firmware storage, configuration data retention, and boot code execution where low-voltage operation and long-term data integrity are critical.
For engineers reviewing the SST39WF1601-90-4I-MBQE-T datasheet, SST39WF1601-90-4I-MBQE-T pinout, SST39WF1601-90-4I-MBQE-T application, or SST39WF1601-90-4I-MBQE-T equivalent, key selection considerations 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 with RST# and WP# control pins.
Technical Context
The SST39WF1601-90-4I-MBQE-T implements SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. It supports uniform 2 KWord sectors and 32 KWord blocks, with sector-, block-, and chip-erase capabilities plus erase-suspend/resume functionality.
It uses standard microprocessor timing for command execution: address latched on falling edge of CE# or WE# (whichever occurs last), data latched on rising edge (whichever occurs first). Status detection relies on DQ6 toggle bit and DQ7 data# polling, with no external VPP required due to internal charge pump generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16 bits); supports full 16-bit data bus interface without byte-lane splitting. |
| Read Access Time | 90 ns max; enables direct execution from flash (XIP) in systems with ≤11 MHz bus timing budgets. |
| Supply Voltage | 1.65–1.95 V; compatible with modern low-power SoC I/O domains and eliminates need for level shifters. |
| Endurance | 100,000 program/erase cycles (typical); sufficient for field firmware updates over 10+ years in industrial controllers. |
| Data Retention | >100 years at 85°C; validated for unpowered storage in automotive ECUs and medical devices. |
| Erase Granularity | 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB); allows fine-grained updates without disturbing adjacent firmware sections. |
| Write Protection | Hardware bottom-block protection (000000H–007FFFH); prevents accidental overwrite of boot code during field upgrades. |
| Security ID | 256-bit space (128-bit factory + 128-bit user); enables device authentication and secure firmware binding. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, lead-free. Pin pitch: 0.5 mm. Ball layout per Figure 3 (SST39WF160x datasheet Rev. 04-000).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus; A19–A0 fully decoded for 1M-word addressing; AMS = A19 for sector/block selection. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; tri-stated when CE# or OE# high; latched internally during write cycles. |
| CE# | Chip Enable | Active-low device select; must be low for read/write; high disables outputs and reduces current to 40 µA (ISB). |
| OE# | Output Enable | Active-low output gate; controls data bus drive; high places DQ0–DQ15 in high-impedance state. |
| WE# | Write Enable | Active-low write strobe; controls latching of address/data and initiates command sequences. |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block; grounded to prevent program/erase in 000000H–007FFFH. |
| RST# | Reset | Active-low hardware reset; terminates ongoing erase/program and forces return to read mode within TRP (≤100 ns). |
| VDD | Power Supply | 1.65–1.95 V core supply; powers logic and SuperFlash array; internal regulator handles VPP generation. |
| VSS | Ground | Reference for all signals; two dedicated VSS balls ensure stable return path for high-speed switching. |
| NC | No Connection | Unbonded balls (e.g., A18, NC positions); must be left floating or tied to VSS per PCB design rules. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash cell architecture | Split-gate + thick-oxide injector enables fixed 36 ms block-erase time across full 100k-cycle lifetime-no software de-rating needed. |
| Auto Low Power mode | Reduces active read current from 10 mA to 40 µA after valid read access-cuts standby power by >99% in intermittently polled systems. |
| Erase-suspend/resume | Allows real-time read/program of non-suspended sectors during background erase-enables responsive UI in HMI applications. |
| JEDEC CFI support | Provides standardized geometry and timing descriptors (Tables 7–9) for automatic driver initialization in Linux/U-Boot environments. |
| Security ID with lock-out | User-programmable 128-bit segment can be permanently locked (via 85H command) to prevent tampering-supports secure boot chain verification. |
| Hardware reset recovery | RST# forces immediate exit from any operation and guarantees deterministic read-mode recovery within TRHR (≤100 ns)-critical for safety-critical resets. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160DTTC-90G | 3.0 V supply (2.7–3.6 V), top-boot configuration, 128-byte buffer programming | Requires level-shifting for 1.8 V systems; top-block protection conflicts with SST39WF1601's bottom-boot layout | Select only if existing 3 V design requires drop-in replacement and boot block location is not constrained. |
| S29GL032N90TFIR20 | 3.0 V supply, 32 Mbit density, 90 ns access, CFI-compliant, no RST# pin | Larger capacity but incompatible voltage domain; lacks hardware reset-requires software reset sequence in bootloader | Prefer for new 3 V designs needing higher density; avoid where RST#-driven fail-safe recovery is mandated. |
Compared with MX29LV160DTTC-90G and S29GL032N90TFIR20, the SST39WF1601-90-4I-MBQE-T uniquely delivers 1.65–1.95 V operation with bottom-boot protection and integrated RST#-making it the only choice for compact, low-power, safety-aware embedded systems requiring guaranteed hardware reset and voltage-aligned I/O.

FAQ
What is the exact memory organization of the SST39WF1601-90-4I-MBQE-T?
The SST39WF1601-90-4I-MBQE-T is organized as 1,048,576 words × 16 bits (1M × 16), totaling 16 Mbit. Its physical address space spans 000000H to 0FFFFFH, with the bottom 32 KWord (000000H–007FFFH) designated as hardware-protected boot block. This structure enables direct 16-bit bus interfacing without byte-lane multiplexing or external glue logic in MPU-based designs.
Does the SST39WF1601-90-4I-MBQE-T require an external VPP voltage for programming?
No, the SST39WF1601-90-4I-MBQE-T does not require an external VPP voltage. It integrates an internal charge pump that generates the necessary high voltage for erase and program operations from the single 1.65–1.95 V VDD supply. This eliminates external high-voltage circuitry, reduces BOM cost, and simplifies PCB layout-confirmed in the "Automatic Write Timing" section of the datasheet.
How does hardware block protection work on the SST39WF1601-90-4I-MBQE-T?
Hardware block protection on the SST39WF1601-90-4I-MBQE-T is implemented via the WP# pin: when WP# is driven low, program and erase operations are disabled for the bottom 32 KWord boot block (000000H–007FFFH). If WP# is left floating, an internal pull-up holds it high, leaving the boot block unprotected. This mechanism operates independently of software commands and persists through power cycles.
What is the purpose of the RST# pin on the SST39WF1601-90-4I-MBQE-T?
The RST# pin on the SST39WF1601-90-4I-MBQE-T provides a hardware-initiated reset that forces the device into read mode regardless of ongoing operations. When asserted low for ≥100 ns (TRP), it terminates active erase or program cycles and restores deterministic read behavior. After release, a minimum hold time (TRHR ≤100 ns) ensures stable output-critical for fail-safe recovery in automotive and industrial systems.
Can the SST39WF1601-90-4I-MBQE-T be used in systems with a 1.8 V I/O domain?
Yes, the SST39WF1601-90-4I-MBQE-T is fully specified for 1.65–1.95 V operation, making it compatible with standard 1.8 V ±5% I/O domains. All DC and AC parameters-including 90 ns read access, 10 mA active current, and 40 µA standby current-are guaranteed across this range. No level shifters or voltage translators are needed for interface with 1.8 V microcontrollers or FPGAs.
