Product details
Overview
SST39WF1602-90-4C-MBQE from Silicon Storage Technology is a 16 Mbit (1M × 16) Multi-Purpose Flash Plus (MPF+) memory IC with top-block hardware write protection, 90 ns read access time, and single-supply 1.65–1.95 V operation. It supports sector/block/chip erase, erase-suspend/resume, and Security ID for secure firmware storage in embedded boot code applications.
For engineers reviewing the SST39WF1602-90-4C-MBQE datasheet, SST39WF1602-90-4C-MBQE pinout, SST39WF1602-90-4C-MBQE application, or SST39WF1602-90-4C-MBQE equivalent, this page delivers verified flash memory specifications including JEDEC-compliant x16 interface timing, 48-ball WFBGA (4mm × 6mm) package mapping, top-boot block protection address range (0F8000H–0FFFFFH), and SuperFlash endurance/reliability metrics critical for industrial firmware storage design.
Technical Context
The SST39WF1602-90-4C-MBQE implements a split-gate SuperFlash cell architecture enabling fixed 28 µs word-program and 36 ms sector/block-erase times independent of cycle count-eliminating software de-rating. Its command-set architecture uses standard microprocessor write sequences with latched address/data on CE# or WE# edges, supporting JEDEC-standard pin assignments and CFI query modes for system compatibility.
Hardware data protection includes noise/glitch immunity (<5 ns pulse rejection), VDD power-up/down detection (<1.5 V inhibit), and dedicated WP# pin enabling top 32 KWord block protection. The RST# pin provides hardware reset to read mode, while DQ6/DQ7 status bits and Data# Polling support real-time end-of-write detection without polling overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 organization), providing 2 MB of nonvolatile storage for boot code and configuration data. |
| Read Access Time | 90 ns maximum - enables direct execution from flash (XIP) in low-latency embedded systems. |
| Supply Voltage | 1.65–1.95 V - compatible with modern low-voltage SoC I/O domains and eliminates need for level shifters. |
| Endurance | 100,000 program/erase cycles - ensures long-term field reliability for firmware update applications. |
| Data Retention | Greater than 100 years - guarantees data integrity across product lifecycle without refresh. |
| Erase Granularity | Uniform 2 KWord sectors and 32 KWord blocks - allows fine-grained updates without full chip erase. |
| Security ID | 256-bit space (128-bit factory + 128-bit user) - supports device authentication and secure firmware binding. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 19-bit address bus (AMS = A19); A0–A11 select sector, A0–A15 select block per JEDEC command protocol. |
| DQ0–DQ15 | Data Input/Output | x16 bidirectional data bus with tri-state outputs controlled by CE# and OE#; latched during write operations. |
| CE# | Chip Enable | Active-low device selection; must be low for all write/erase operations and read access. |
| OE# | Output Enable | Active-low output gating; high-Z state when asserted high or CE# high - prevents bus contention. |
| WE# | Write Enable | Controls latching edge for address/data during command sequences; falling edge latches address, rising edge latches data. |
| WP# | Write Protect | Active-low top-boot block protection (0F8000H–0FFFFFH); grounded to lock 32 KWord region against accidental erase/program. |
| RST# | Reset | Hardware abort of in-progress operations; forces return to read mode within TRP (min 100 ns). |
| VDD / VSS | Power / Ground | Single 1.65–1.95 V supply; dual VSS balls ensure low-noise ground return for stable high-speed operation. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1602-90-4C-EKE | 3.0 V supply (2.7–3.6 V), same density and pinout but higher voltage - incompatible with 1.8 V I/O domains. | Lacks Auto Low Power mode and has lower endurance (10,000 cycles vs. 100,000). | Select only if legacy 3 V system integration required; not suitable for new low-power designs. |

FAQ
What is the exact memory organization of the SST39WF1602-90-4C-MBQE?
The SST39WF1602-90-4C-MBQE is organized as 1M × 16, delivering 16 Mbit (2 MB) of nonvolatile storage. Its address space spans 000000H to 0FFFFFH, with top 32 KWord (0F8000H–0FFFFFH) designated as hardware-protected boot block. This x16 interface supports byte-wide or word-wide data transfers depending on system bus configuration.
Does the SST39WF1602-90-4C-MBQE support both sector and block erase operations?
Yes, the SST39WF1602-90-4C-MBQE supports uniform 2 KWord sector erase and 32 KWord block erase via distinct six-byte command sequences. Sector erase targets individual 4 KB regions using A0–A11, while block erase addresses 64 KB regions using A0–A15. Both operations support erase-suspend/resume and status detection via DQ6 toggle or DQ7 polling.
How does hardware block protection work on the SST39WF1602-90-4C-MBQE?
The SST39WF1602-90-4C-MBQE implements top-block hardware protection: grounding the WP# pin disables program/erase operations on the top 32 KWord (0F8000H–0FFFFFH). If WP# floats, an internal pull-up keeps it high, leaving the boot block unprotected. This mechanism operates independently of software commands and survives power cycles.
What is the purpose of the RST# pin on the SST39WF1602-90-4C-MBQE?
The RST# pin on the SST39WF1602-90-4C-MBQE provides hardware-level reset functionality. Holding RST# low for ≥100 ns (TRP) terminates any in-progress program or erase operation and forces immediate return to read mode. After release, a minimum TRHR delay (≥100 ns) is required before valid reads can resume - ensuring state recovery.
Can the SST39WF1602-90-4C-MBQE be used in 1.8 V systems without level shifting?
Yes, the SST39WF1602-90-4C-MBQE operates natively across 1.65–1.95 V, making it fully compatible with standard 1.8 V I/O domains. Its CMOS I/O structure meets JEDEC x16 flash pin assignments, eliminating need for external level shifters. All control signals (CE#, OE#, WE#, WP#, RST#) and data lines (DQ0–DQ15) are 1.8 V tolerant.
