Product details
Overview
SST39WF1601-70-4C-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 70 ns read access time, bottom 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface - used for firmware storage and configuration in embedded controllers and industrial HMI systems.
For engineers reviewing the SST39WF1601-70-4C-MBQE-T datasheet, SST39WF1601-70-4C-MBQE-T pinout, SST39WF1601-70-4C-MBQE-T application, or SST39WF1601-70-4C-MBQE-T equivalent, key selection considerations include its 48-ball WFBGA (5 mm × 6 mm) package, bottom-boot block protection scheme, 100,000-cycle endurance, Auto Low Power mode (5 µA), and CFI-compliant identification for bootloader compatibility.
Technical Context
The SST39WF1601-70-4C-MBQE-T implements SuperFlash split-gate technology enabling fixed erase/program times independent of cycle count, eliminating system de-rating over lifetime. It supports Word-Program (28 µs typical), Sector-Erase (36 ms), Block-Erase (36 ms), and Chip-Erase (140 ms), with status detection via DQ6 toggle bit and DQ7 data# polling.
Hardware protection includes WP#-controlled bottom 32 KWord boot block lock, RST#-initiated hard reset to read mode, and noise/glitch immunity (<5 ns pulse rejection). It complies with JEDEC standard pinouts and command sets, and supports both SST-specific and general CFI Query modes for host auto-configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 organization) - supports 16-bit parallel bus interface without external data-width conversion. |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) in low-latency microcontroller boot applications. |
| 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 - sufficient for field firmware updates over 10+ years in industrial control systems. |
| Data Retention | >100 years - ensures configuration integrity across product lifecycle without refresh. |
| Standby Current | 5 µA typical - reduces quiescent power in always-on edge nodes and battery-backed modules. |
| Erase Granularity | Uniform 2 KWord sectors and 32 KWord blocks - allows fine-grained firmware patching and robust recovery partitioning. |
Pinout & Package
Package: 48-ball WFBGA (5 mm × 6 mm), RoHS-compliant, non-Pb.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 1M × 16 addressing (A0–A18 active; A19 = AMS for sector/block selection); latched on falling edge of CE# or WE#. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; tri-stated when CE# or OE# high; latched on rising edge of CE# or WE# during write. |
| CE# | Chip Enable | Active-low device select; must be low for read/write; controls standby entry when high. |
| OE# | Output Enable | Active-low output gate; enables data output only when CE# and OE# both low. |
| WE# | Write Enable | Controls timing of address/data latching and initiates internal program/erase operations. |
| WP# | Write Protect | Low = locks bottom 32 KWord boot block (000000H–007FFFH); floating = internally pulled high (unprotected). |
| 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 aging compensation and simplifies timing margins. |
| Bottom Boot Block Protection | Hardware-enforced lock on 000000H–007FFFH (32 KWord) - safeguards bootloader code against accidental overwrite during field updates. |
| Erase-Suspend/Resume | Allows read access to non-suspended sectors during erase - enables real-time status reporting and interruptible firmware updates. |
| Security ID Space | 256-bit factory + user programmable ID (128 + 128 bits) - supports device authentication and secure provisioning in IoT endpoints. |
| CFI Compliance | Supports both SST-specific and JEDEC general CFI Query modes - enables automatic driver initialization in Linux U-Boot and RTOS BSPs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601-70-4C-EKE-T | 3.0–3.6 V operation; same density, pinout, and command set; lacks Auto Low Power mode (standby = 12 µA). | Requires external voltage translation in 1.8 V systems; suitable only where higher VDD is available. | Select only if legacy 3.3 V design constraints exist and ultra-low standby current is not required. |
| MX29LV160DTTI-70G | 3.0–3.6 V; 48-pin TSOP package; identical 1M×16 organization and 70 ns access but no CFI support or Security ID. | Not pin-compatible (TSOP vs WFBGA); requires PCB redesign; no secure provisioning capability. | Consider only for cost-sensitive, non-secure, through-hole or TSOP-based designs with existing layout support. |
Compared with SST39VF1601-70-4C-EKE-T and MX29LV160DTTI-70G, the SST39WF1601-70-4C-MBQE-T uniquely delivers 1.8 V compatibility, 5 µA Auto Low Power mode, bottom-boot hardware protection, and 256-bit Security ID - making it the only option qualified for new energy-efficient, secure, surface-mount embedded systems.

FAQ
What is the operating voltage range for the SST39WF1601-70-4C-MBQE-T?
The SST39WF1601-70-4C-MBQE-T operates exclusively within 1.65 V to 1.95 V. This narrow low-voltage window eliminates compatibility with 3.3 V or 5 V systems and requires tight regulation - typically supplied directly from an SoC's 1.8 V I/O rail. Operation outside this range may cause command failure or data corruption, and the device will inhibit writes below 1.5 V per internal power-up detection.
How does the bottom boot block protection work on the SST39WF1601-70-4C-MBQE-T?
The SST39WF1601-70-4C-MBQE-T implements hardware bottom boot block protection on address range 000000H–007FFFH (32 KWord). When WP# is driven low, all program and erase commands targeting this region are ignored. If WP# is left floating, an internal pull-up holds it high, disabling protection. This mechanism is independent of software data protection and provides fail-safe bootloader integrity.
Does the SST39WF1601-70-4C-MBQE-T support CFI (Common Flash Interface)?
Yes, the SST39WF1601-70-4C-MBQE-T supports both SST-specific and JEDEC general CFI Query modes. Entering CFI mode allows host systems to auto-detect geometry, timing, and command set - critical for generic flash drivers in U-Boot, Linux MTD, and RTOS BSPs. The CFI data resides at standardized offsets and includes device size, erase block structure, and timeout parameters.
What is the purpose of the RST# pin on the SST39WF1601-70-4C-MBQE-T?
The RST# pin on the SST39WF1601-70-4C-MBQE-T provides hardware-initiated recovery: holding RST# low for ≥TRP (typically 100 ns) forces immediate termination of any ongoing program or erase operation and returns the device to read mode. After release, a minimum TRHR delay (≥50 ns) is required before valid reads. This enables deterministic fault recovery in safety-critical firmware stacks.
Can the SST39WF1601-70-4C-MBQE-T be used in place of the SST39WF1602-70-4C-MBQE-T?
No - the SST39WF1601-70-4C-MBQE-T and SST39WF1602-70-4C-MBQE-T differ in boot block location and protection: SST39WF1601 protects the bottom 32 KWord (000000H–007FFFH), while SST39WF1602 protects the top 32 KWord (0F8000H–0FFFFFH). Their device IDs (BF274B vs BF274A) and boot address maps are incompatible; swapping them risks bootloader corruption.
