Product details
Overview
SST39WF1602-90-4I-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 90 ns read access time, top 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface - used for firmware storage in industrial microcontroller boot systems.
For engineers reviewing the SST39WF1602-90-4I-MBQE datasheet, SST39WF1602-90-4I-MBQE pinout, SST39WF1602-90-4I-MBQE application, or SST39WF1602-90-4I-MBQE equivalent, this page delivers verified flash timing, sector/block erase behavior, WP#-controlled boot-block protection, Auto Low Power mode current (5 µA), and CFI-compliant identification - all confirmed for the exact MBQE WFBGA package variant.
Technical Context
The SST39WF1602-90-4I-MBQE implements SuperFlash split-gate technology with thick-oxide tunneling injector, enabling fixed 28 µs word-program and 36 ms sector/block-erase times independent of endurance cycles. It supports JEDEC-standard command sets including Software Data Protection (SDP) and Common Flash Interface (CFI) query modes.
Its architecture includes latched address/data buses, dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits), Erase-Suspend/Resume capability, and hardware reset (RST#) for operation recovery. The device uses internal VPP generation and requires no external high-voltage supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1M × 16 (16 Mbit total); enables 16-bit parallel data bus interfacing with MCUs and SoCs without glue logic. |
| Read Access Time | 90 ns (max); guarantees deterministic boot code fetch latency in real-time embedded systems. |
| Supply Voltage | 1.65–1.95 V; compatible with low-voltage I/O domains of modern ARM Cortex-M and RISC-V processors. |
| Endurance | 100,000 program/erase cycles (typical); supports field firmware updates over 10+ years in industrial deployments. |
| Data Retention | >100 years; ensures nonvolatile storage integrity across product lifecycle without refresh. |
| Erase Granularity | Uniform 2 KWord sectors & 32 KWord blocks; allows fine-grained firmware partitioning (e.g., bootloader + app + config). |
| Block Protection | Top 32 KWord hardware protection (WP#-enabled); safeguards bootloader region against accidental overwrite. |
| Standby Current | 5 µA (typical); minimizes quiescent power in always-on edge devices and battery-backed systems. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, lead-free - footprint matches JEDEC MO-244AC standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus; A19–A11 select 32 KWord blocks, A10–A0 select 2 KWord sectors during erase. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; tri-stated when CE# or OE# high; supports latched read/write timing. |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write; high forces standby (5 µA ISB). |
| OE# | Output Enable | Active-low output gate; controls data bus drive; high places outputs in high-impedance state. |
| WE# | Write Enable | Active-low write strobe; latches address/data on falling/rising edges per JEDEC timing protocol. |
| WP# | Write Protect | Active-low hardware lock; when grounded, prevents program/erase of top 32 KWord boot block (0F8000H–0FFFFFH). |
| RST# | Reset | Active-low hardware reset; terminates in-progress operations and returns device to read mode within TRP. |
| VDD | Power Supply | 1.65–1.95 V core supply; powers internal charge pump for erase/program; no external VPP required. |
| VSS | Ground | Reference ground for all I/O and core logic; two dedicated VSS balls ensure low-noise operation. |
| NC | No Connection | Unbonded balls (e.g., A18, A19 on some rows); must remain unconnected per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide injector enables fixed 28 µs program and 36 ms erase times across full endurance life. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid read access - no software intervention required. |
| Erase-Suspend/Resume | Allows reading from non-suspended sectors or programming other blocks during ongoing sector/block erase. |
| Security ID Space | 256-bit factory/user programmable ID (128-bit locked SST ID + 128-bit customer-programmable segment). |
| CFI Query Support | Both SST-specific and general CFI modes supported; enables automatic driver detection in OS/bootloader stacks. |
| Hardware Block Protection | Top 32 KWord (0F8000H–0FFFFFH) protected when WP# = low - prevents corruption of critical boot code. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1602-90-4I-MBQE | 3.0 V supply (2.7–3.6 V), slower 90 ns access, same 1M×16 organization and WFBGA-48 package. | Requires higher VDD; not suitable for 1.8 V core systems but offers broader voltage margin in legacy designs. | Select only if system VDD ≥ 2.7 V and backward compatibility with SST39VF family is required. |
| MX29LV160ETTI-90G | 3.0 V supply, 1M×16, 90 ns, top-boot configuration, but lacks Auto Low Power mode and Erase-Suspend. | Lower standby current (1 µA) but no suspend/resume; incompatible CFI implementation limits bootloader portability. | Use where ultra-low standby dominates over field-upgrade flexibility; verify SDP command set compatibility before migration. |
Compared with SST39VF1602-90-4I-MBQE and MX29LV160ETTI-90G, the SST39WF1602-90-4I-MBQE uniquely delivers 1.8 V operation, fixed-program timing, and Erase-Suspend - essential for power-constrained, update-capable embedded systems.

FAQ
What is the exact package type and dimensions of the SST39WF1602-90-4I-MBQE?
The SST39WF1602-90-4I-MBQE uses a 48-ball WFBGA package measuring 4 mm × 6 mm with 0.5 mm ball pitch, per JEDEC MO-244AC. This matches the "MBQE" suffix designation in the part number and is distinct from the TFBGA (6 mm × 8 mm) variant. Pin assignments follow Figure 3 in the official datasheet S71297-04-000.
Does the SST39WF1602-90-4I-MBQE support both top-boot and bottom-boot configurations?
No - the SST39WF1602-90-4I-MBQE supports top-boot configuration only, protecting the upper 32 KWord block (address range 0F8000H–0FFFFFH) when WP# is low. The bottom-boot variant is the SST39WF1601. This distinction is hardwired in silicon and cannot be changed via software or pin strapping.
How does the Auto Low Power mode function in the SST39WF1602-90-4I-MBQE?
The SST39WF1602-90-4I-MBQE enters Auto Low Power mode automatically after a valid read cycle completes, reducing active current from ~9 mA to 5 µA. It exits instantly on any address or control signal transition (e.g., CE# toggle) with zero access time penalty - no command or register setting is required.
Can the SST39WF1602-90-4I-MBQE be used in a 3.3 V system?
No - the SST39WF1602-90-4I-MBQE is rated strictly for 1.65–1.95 V operation. Applying 3.3 V will exceed absolute maximum ratings and cause permanent damage. For 3.3 V systems, consider the pin-compatible SST39VF1602 or MX29LV160 series instead.
What command sequences are required to read the Security ID of the SST39WF1602-90-4I-MBQE?
To read the Security ID, issue the three-byte Enter Sec ID command: write 0xAA to address 0x5555, 0x55 to address 0x2AAA, then 0x88 to address 0x5555. SST factory ID (128 bits) appears at addresses 000000H–000007H; user ID (128 bits) appears at 000008H–00000FH. Exit using the F0H command sequence.
