Product details
Overview
SST39WF1601-70-4C-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, bottom 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface - used for firmware storage and configuration in embedded microcontroller systems.
For engineers reviewing the SST39WF1601-70-4C-MBQE datasheet, SST39WF1601-70-4C-MBQE pinout, SST39WF1601-70-4C-MBQE application, or SST39WF1601-70-4C-MBQE equivalent, key selection considerations include its WFBGA-48 package, 100,000-cycle endurance, Auto Low Power mode (5 µA standby), sector/block/chip erase capabilities, and hardware write-protection via WP# tied low to protect boot code in bottom 32 KWord.
Technical Context
The SST39WF1601-70-4C-MBQE implements SuperFlash split-gate technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It supports standard JEDEC command sets including Software Data Protection (SDP) with three-byte unlock sequences for program and six-byte sequences for erase operations.
It features dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits), CFI Query support (SST and general modes), and hardware reset (RST#) for forced return to read mode. The device uses latched address/data buses and requires CE#/OE#/WE# control logic compatible with legacy x16 parallel flash interfaces.
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 MCUs. |
| Read Access Time | 70 ns - enables direct execution (XIP) from flash in timing-critical boot sequences. |
| Supply Voltage | 1.65–1.95 V - matches modern low-voltage SoC I/O domains without level-shifting. |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over product lifetime. |
| Data Retention | >100 years - ensures long-term reliability in unpowered industrial deployments. |
| Erase Granularity | 2 KWord sectors / 32 KWord blocks / full chip - allows fine-grained update of bootloader, app, or config partitions. |
| Protection Scheme | Hardware bottom-block protection (000000H–007FFFH) + WP# pin - prevents accidental overwrite of critical boot code. |
| Package | 48-ball WFBGA (5 mm × 6 mm) - compact footprint for space-constrained PCBs with high I/O density. |
Pinout & Package
Package: 48-ball WFBGA (5 mm × 6 mm), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 16-bit address bus (A0–A15) + 4 MSBs (A16–A19); AMS = A19 selects sector/block during erase. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; tri-stated when CE# or OE# high; latched on WE#/CE# edges. |
| CE# | Chip Enable | Active-low chip select; device enters standby (5 µA) when high; required low for all operations. |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; high disables outputs. |
| WE# | Write Enable | Active-low write strobe; controls latching of addresses/data and initiates internal program/erase timing. |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord block (000000H–007FFFH); floating = internally pulled high. |
| RST# | Reset | Active-low hardware reset; terminates ongoing operation and forces return to read mode within TRP. |
| VDD | Power Supply | 1.65–1.95 V core supply; powers all logic and SuperFlash array; no external VPP required. |
| VSS | Ground | Reference ground for all signals and internal circuitry; decoupling required per layout guidelines. |
| NC | No Connection | Unbonded balls (e.g., pins C3, E3, G3, J3, K3, L3 per Figure 2); must remain unconnected on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with fixed 36 ms sector/block erase time - eliminates software de-rating across lifetime. |
| Erase-Suspend/Resume | Allows read/program from non-suspended sectors during active erase - enables real-time diagnostics or UI updates. |
| Security ID Space | 256-bit factory + user programmable ID (128 + 128 bits) - supports device authentication and secure provisioning. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid access - cuts dynamic power in burst-read applications. |
| CFI Compliance | Supports both SST-specific and JEDEC general CFI Query modes - enables OS/driver auto-detection and generic flash drivers. |
| Hardware Block Protection | Bottom 32 KWord (256 KB) protected when WP# = low - safeguards bootloader against corruption during field updates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160DBTI-70G | 3.0 V supply (2.7–3.6 V), 48-pin TSOP, top-boot configuration, no Auto Low Power mode | Lacks low-voltage operation and ultra-low standby current; requires level-shifting for 1.8 V systems | Select only if legacy 3 V design exists and board-level voltage translation is acceptable. |

FAQ
What is the correct power supply range for SST39WF1601-70-4C-MBQE?
The SST39WF1601-70-4C-MBQE operates strictly within 1.65 V to 1.95 V for both read and write operations. Operation outside this range - including at 3.3 V or below 1.65 V - will cause functional failure or permanent damage. The device includes internal VPP generation, eliminating need for external high-voltage programming supplies. This voltage range is verified in Table 10 of the official EOL datasheet.
How does hardware block protection work on SST39WF1601-70-4C-MBQE?
Hardware block protection on the SST39WF1601-70-4C-MBQE locks the bottom 32 KWord (000000H–007FFFH) when WP# is driven low. This prevents program/erase commands from affecting that region. If WP# floats, an internal pull-up holds it high, disabling protection. This behavior is specific to the SST39WF1601 variant and differs from the top-block protection of SST39WF1602.
Does SST39WF1601-70-4C-MBQE support CFI Query mode?
Yes, the SST39WF1601-70-4C-MBQE supports both SST-specific and JEDEC general CFI Query modes. Entry requires either a three-byte sequence (5555H/AAH → 2AAAH/55H → 5555H/98H) for SST mode or a one-byte sequence (55H/98H) for general mode. CFI data is accessible at defined offsets (Tables 7–9) and confirms device geometry, timing, and command set compliance.
What is the purpose of the RST# pin on SST39WF1601-70-4C-MBQE?
The RST# pin on SST39WF1601-70-4C-MBQE provides hardware-initiated recovery: holding RST# low for ≥TRP (≥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 (≥100 ns) is required before valid reads. This feature is essential for system-level fault recovery and watchdog integration.
Can SST39WF1601-70-4C-MBQE be used in place of SST39WF1602?
No - SST39WF1601-70-4C-MBQE and SST39WF1602 differ in hardware block protection location (bottom vs. top 32 KWord) and device ID (BF274B vs. BF274A). They share pinout and command set but are not functionally interchangeable without firmware and layout review. Using SST39WF1601-70-4C-MBQE where SST39WF1602 is specified risks unprotected boot code execution.
