Product details
Overview
SST39WF1602-70-4C-MBQE 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 70 ns read access time, top 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface. It is used for firmware storage and configuration in embedded controllers requiring low-voltage, high-reliability nonvolatile memory.
For engineers reviewing the SST39WF1602-70-4C-MBQE datasheet, SST39WF1602-70-4C-MBQE pinout, SST39WF1602-70-4C-MBQE application, or SST39WF1602-70-4C-MBQE equivalent, key selection criteria include its 1.65–1.95 V single-supply operation, WFBGA-48 package with 5 mm × 6 mm footprint, top-boot block protection scheme, SuperFlash endurance (100,000 cycles), and erase-suspend/resume capability for real-time firmware updates.
Technical Context
The SST39WF1602-70-4C-MBQE implements a split-gate SuperFlash cell architecture enabling fixed erase/program times independent of cycle count, eliminating software de-rating. Its command-set follows JEDEC standard pin assignments and supports CFI Query mode for host auto-configuration.
It features dual status detection (DQ6 toggle bit and DQ7 data# polling) for write completion monitoring, hardware reset (RST#) for forced return to read mode, and dedicated WP# input for top-block protection. The device supports sector-erase (2 KWord), block-erase (32 KWord), chip-erase, and erase-suspend/resume operations-all executed via standardized six-byte command sequences.
Key Specifications

Pinout & Package
Package: 48-ball WFBGA (5 mm × 6 mm), RoHS-compliant, lead-free, bottom-side ball layout per Figure 2 of EOL datasheet S71297(05)-00-EOL.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 1M × 16 addressing (20-bit); AMS = A19 selects top/bottom boot block during protection setup |
| DQ0–DQ15 | Data I/O | x16 bidirectional bus; tri-stated when CE# or OE# high; latched on WE#/CE# edges during writes |
| CE# | Chip Enable | Active-low device select; must be low for all write operations and valid reads |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; high = high-impedance |
| WE# | Write Enable | Controls latching of address/data during programming/erasing; falling edge latches address |
| WP# | Write Protect | Active-low top-block lock; grounded to protect 0F8000H–0FFFFFH (32 KWord) from erase/program |
| RST# | Hardware Reset | Active-low hard reset; terminates in-progress operations and forces return to read mode |
| VDD | Power Supply | 1.65–1.95 V core supply; internal charge pump generates VPP for erase/program |
| VSS | Ground | Reference ground for all I/O and core logic; multiple balls ensure low-impedance return path |
| NC | No Connection | Unbonded pins (e.g., balls at positions C1, D1, G1, H1, J1, K1, L1, L2, L3, L4, L5, L6); must be left floating |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows real-time read access to unprotected sectors during active erase-enables background firmware validation |
| Security ID Space | 256-bit factory + user programmable ID (128 + 128 bits), locked after programming to prevent tampering |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid read-cuts dynamic power by >99% during idle polling |
| SuperFlash Cell Architecture | Fixed 36 ms sector/block erase and 28 µs word-program times across full lifecycle-no software timing margining required |
| JEDEC CFI Compliance | Supports both SST-specific and general CFI Query modes-enables automatic driver initialization in Linux/BSP environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160ETTI-70G | 3.0 V supply (2.7–3.6 V), 48-pin TSOP, no erase-suspend, no Security ID | Lacks low-voltage operation and real-time suspend capability; requires voltage translation in 1.8 V systems | Select only if legacy 3 V design exists and erase-suspend is not required |
| S29GL032N90TFI010 | 3.0 V supply, 56-ball BGA, 48 Mbit density, no top/bottom block-selectable protection | Higher density but incompatible voltage and protection model; requires PCB redesign | Consider only for new designs needing >16 Mbit and willing to accept 3 V interface constraints |

FAQ
What is the operating voltage range for the SST39WF1602-70-4C-MBQE?
The SST39WF1602-70-4C-MBQE operates exclusively within a 1.65–1.95 V supply range. This single-voltage specification eliminates need for external level shifters in 1.8 V systems and ensures compatibility with modern low-power microcontrollers. Operation outside this range may cause undefined behavior or permanent damage, as confirmed in the Absolute Maximum Ratings table of the EOL datasheet S71297(05)-00-EOL.
How does hardware block protection work on the SST39WF1602-70-4C-MBQE?
The SST39WF1602-70-4C-MBQE implements top 32 KWord hardware block protection: when WP# is driven low, program and erase operations are disabled for addresses 0F8000H–0FFFFFH. This protects boot code from accidental overwrite. Unlike software-based locks, this protection remains active even during power transitions and requires no firmware initialization-ensuring robustness in safety-critical applications.
Does the SST39WF1602-70-4C-MBQE support erase-suspend functionality?
Yes, the SST39WF1602-70-4C-MBQE supports erase-suspend/resume via the B0H command. When issued during sector or block erase, it pauses the operation within 20 µs, allowing reads from unprotected locations or programming of non-suspended sectors. Resume uses the 30H command. This feature is essential for real-time systems where firmware updates must not interrupt critical I/O tasks.
What package type is used for the SST39WF1602-70-4C-MBQE?
The SST39WF1602-70-4C-MBQE uses a 48-ball WFBGA package measuring 5 mm × 6 mm with 0.5 mm pitch. Pin assignments match Figure 2 of the EOL datasheet S71297(05)-00-EOL, including NC balls at positions C1, D1, G1, H1, J1, K1, L1–L6. This package supports high-density PCB layouts and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3 requirements.
Can the SST39WF1602-70-4C-MBQE be used in industrial temperature applications?
Yes, the SST39WF1602-70-4C-MBQE is rated for industrial temperature operation from –40°C to +85°C, as specified in the Operating Range table of the EOL datasheet. All electrical characteristics-including 70 ns read access, 100,000-cycle endurance, and 5 µA standby current-are guaranteed across this full range, making it suitable for deployment in harsh environments like factory automation and outdoor networking gear.
