Product details
Overview
SST39WF1602-70-4I-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 70 ns read access time, top 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface - used for firmware storage and configuration in industrial embedded controllers.
For engineers reviewing the SST39WF1602-70-4I-MBQE datasheet, SST39WF1602-70-4I-MBQE pinout, SST39WF1602-70-4I-MBQE application, or SST39WF1602-70-4I-MBQE equivalent, this page delivers verified flash endurance (100,000 cycles), sector/block/chip erase capabilities, Auto Low Power mode (5 µA), Security ID support, and WFBGA-48 package mapping - all confirmed from official EOL documentation.
Technical Context
The SST39WF1602-70-4I-MBQE implements SuperFlash split-gate technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It supports JEDEC-standard command sets including CFI Query, Software ID Entry, and Erase-Suspend/Resume.
It uses latched address/data I/Os, CMOS-compatible signaling, and dual status detection (DQ6 toggle + DQ7 polling) for write completion. Hardware block protection is activated via WP# pin grounding to lock the top 32 KWord boot block (0F8000H–0FFFFFH), while RST# provides hardware reset to read mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words) - supports full firmware image storage for mid-complexity microcontrollers. |
| Read Access Time | 70 ns - enables direct execution (XIP) from flash in systems with ≤14 MHz bus timing budgets. |
| Supply Voltage | 1.65–1.95 V - compatible with low-voltage SoC I/O domains and eliminates need for level shifters. |
| Endurance | 100,000 program/erase cycles - sufficient for field-upgradable firmware with infrequent updates. |
| Data Retention | >100 years - validated for long-lifecycle industrial deployments without refresh. |
| Erase Granularity | Uniform 2 KWord sectors & 32 KWord blocks - allows selective firmware patching without full chip erase. |
| Security ID | 256-bit (128-bit factory + 128-bit user) - enables device authentication and secure boot key binding. |
Pinout & Package
Package: 48-ball WFBGA (5 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, non-Pb.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 16-bit address bus (A0–A15) + 4 MSBs (A16–A19); AMS = A19 selects top/bottom boot block during protection. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with tri-state output control via CE# and OE#; latched on WE#/CE# edges. |
| CE# | Chip Enable | Active-low chip select; device enters standby (40 µA) when high; required low for all operations. |
| OE# | Output Enable | Active-low output gate; controls data bus drive; high = high-impedance state. |
| WE# | Write Enable | Active-low write strobe; latches addresses/data and initiates internal program/erase sequences. |
| WP# | Write Protect | Active-low hardware block protect; grounded to lock top 32 KWord (0F8000H–0FFFFFH) against erase/program. |
| RST# | Reset | Active-low hardware reset; terminates ongoing operation and forces return to read mode within TRP. |
| VDD / VSS | Power / Ground | Single 1.65–1.95 V supply; no VPP required - internal charge pump generates programming voltage. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Fixed 28 µs word-program and 36 ms sector/block-erase times - eliminates software de-rating over lifetime. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid read - cuts dynamic power by >99% during idle fetches. |
| Erase-Suspend/Resume | Pauses erase to allow reads or programming elsewhere - enables real-time firmware update without halting system. |
| Hardware Block Protection | Top 32 KWord (SST39WF1602 only) locked via WP# - prevents accidental overwrite of boot code in field-deployed units. |
| Security ID Space | Factory-locked 128-bit ID + user-programmable 128-bit space - supports cryptographic key binding and anti-cloning. |

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 Security ID, bottom-boot only | Lacks Auto Low Power mode and hardware top-block protection; requires level-shifting for 1.8 V systems | Choose if legacy 3 V design exists and top-block protection is unnecessary. |
| S29GL032N90TFI010 | 3.0 V supply, 56-pin TSOP, 32 Mbit density, no WP#-based hardware protection | Higher density but incompatible voltage range; uses software-only protection and lacks Security ID | Prefer only when migrating to larger capacity and accepting software-based security model. |

FAQ
What is the guaranteed endurance rating for SST39WF1602-70-4I-MBQE?
The SST39WF1602-70-4I-MBQE is rated for 100,000 program/erase cycles - a typical value confirmed in the official EOL datasheet. This endurance is enabled by SuperFlash split-gate cell architecture and remains stable across the full temperature range (-40°C to +85°C). The SST39WF1602-70-4I-MBQE maintains this specification without degradation over time due to fixed erase/program timing.
Does SST39WF1602-70-4I-MBQE support both top and bottom hardware block protection?
No - the SST39WF1602-70-4I-MBQE supports top 32 KWord hardware block protection only (address range 0F8000H–0FFFFFH), activated when WP# is grounded. The SST39WF1601 variant supports bottom-block protection instead. This distinction is hardwired per part number and cannot be configured in-circuit. The SST39WF1602-70-4I-MBQE does not support bottom-block protection.
What package type and dimensions does SST39WF1602-70-4I-MBQE use?
The SST39WF1602-70-4I-MBQE uses a 48-ball WFBGA package measuring 5 mm × 6 mm with 0.5 mm ball pitch. Pin assignments match Figure 2 of the EOL datasheet, including dedicated WP# and RST# pins. This package is lead-free and RoHS compliant, with reflow profile rated for 260°C for 10 seconds.
Can SST39WF1602-70-4I-MBQE operate without external VPP voltage?
Yes - the SST39WF1602-70-4I-MBQE generates all internal programming voltages using an on-chip charge pump. It requires only a single 1.65–1.95 V supply (VDD) for both read and write operations. No external VPP pin or voltage source is needed, simplifying power design and PCB layout. This is explicitly stated in Table 8 of the EOL datasheet.
How is end-of-write detection implemented in SST39WF1602-70-4I-MBQE?
The SST39WF1602-70-4I-MBQE provides two hardware-supported methods: Data# Polling (DQ7 toggles until operation completes, then returns true data) and Toggle Bit (DQ6 toggles during operation, stops when complete). Both are valid after the rising edge of the fourth (program) or sixth (erase) WE# pulse. These mechanisms eliminate need for fixed delay loops and enable deterministic host software flow control.
