Product details
Overview
SST39WF1601-90-4I-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 bottom-block hardware protection, 90 ns read access time, and 48-ball WFBGA (4 mm × 6 mm) packaging. It delivers 100,000 program/erase cycles and >100 years data retention for embedded firmware storage in industrial microcontroller systems.
For engineers reviewing the SST39WF1601-90-4I-MBQE datasheet, SST39WF1601-90-4I-MBQE pinout, SST39WF1601-90-4I-MBQE application, or SST39WF1601-90-4I-MBQE equivalent, this page provides verified pin functions, JEDEC-compliant command set details, bottom-boot block protection mapping, and direct alternatives with documented sector/block erase timing differences.
Technical Context
The SST39WF1601-90-4I-MBQE implements SuperFlash split-gate technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its x16 asynchronous interface supports standard microprocessor bus protocols using CE#, OE#, and WE# control signals with latched address/data timing.
It integrates hardware block protection on the bottom 32 KWord (000000H–007FFFH), RST# for hard reset to read mode, WP# for boot-block write inhibition, and dual status detection via DQ7 (Data# Polling) and DQ6/DQ2 (Toggle Bits). CFI Query mode (SST and general) and 256-bit Security ID (128-bit factory + 128-bit user) are fully implemented.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16), directly replaces legacy x16 NOR flash in boot code storage without bus width conversion. |
| Read Access Time | 90 ns - guarantees deterministic instruction fetch latency for real-time MCU boot sequences. |
| Supply Voltage | 1.65–1.95 V - enables direct integration with low-voltage SoC I/O domains without level-shifting. |
| Endurance | 100,000 program/erase cycles - supports field firmware updates over full product lifecycle in industrial controllers. |
| Data Retention | >100 years - ensures nonvolatile storage integrity across extended shelf life and operating temperature range (–40°C to +85°C). |
| Erase Granularity | Uniform 2 KWord sectors and 32 KWord blocks - allows precise firmware patching without full chip erase overhead. |
| Write Protection | Hardware bottom-block protection (000000H–007FFFH) - prevents accidental overwrite of bootloader region when WP# is grounded. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, lead-free. Pin assignments conform to JEDEC-standard x16 flash pinout with dedicated RST# and WP# control inputs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | AMS = A19; A11 selects sector during Sector-Erase; A15 selects block during Block-Erase. |
| DQ0–DQ15 | Data I/O | x16 bidirectional bus; tri-stated when CE# or OE# high; latched on rising edge of WE#/CE# during writes. |
| CE# | Chip Enable | Active-low device selection; must be low for all write operations and valid reads. |
| OE# | Output Enable | Active-low output gating; controls data bus drive during read; high = high-Z state. |
| WE# | Write Enable | Controls write timing; falling edge latches address, rising edge latches data per JEDEC protocol. |
| WP# | Write Protect | Grounding protects bottom 32 KWord boot block (000000H–007FFFH); floating = internally pulled high = unprotected. |
| RST# | Hardware Reset | Forces immediate return to Read mode; requires TRP low pulse; TRHR delay before valid read post-reset. |
| VDD | Power Supply | 1.65–1.95 V only; internal VPP generation eliminates external high-voltage supply requirement. |
| VSS | Ground | Two dedicated ground balls for noise immunity in high-speed read/write transitions. |
| NC | No Connection | Unbonded pins; no electrical function; must remain unconnected per design. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows read access to non-suspended sectors during active erase, enabling real-time status monitoring without halting firmware update. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid read, cutting dynamic power by >99% during idle polling intervals. |
| Security ID Space | 256-bit segmented space (128-bit factory-locked + 128-bit user-programmable) for secure device authentication and firmware binding. |
| Fixed Timing Architecture | SuperFlash cell design ensures constant 36 ms sector/block erase and 28 µs word-program times regardless of accumulated cycles. |
| JEDEC Command Compliance | Fully implements standard x16 flash command sets (including CFI Query, Product ID, Erase Suspend) for drop-in compatibility with existing flash drivers. |

FAQ
What is the exact boot block protection scheme implemented in SST39WF1601-90-4I-MBQE?
The SST39WF1601-90-4I-MBQE implements bottom-block hardware protection covering the lowest 32 KWord address range (000000H–007FFFH). This protection is activated when the WP# pin is held low; if WP# is left floating, an internal pull-up disables protection. The SST39WF1601-90-4I-MBQE datasheet confirms this behavior is exclusive to the "1" variant, distinguishing it from the top-protected SST39WF1602.
Does SST39WF1601-90-4I-MBQE support CFI Query mode, and which variants are implemented?
Yes, SST39WF1601-90-4I-MBQE supports both SST-specific and general CFI Query modes. Entry to SST CFI mode uses the three-byte sequence (5555H/AAH → 2AAAH/55H → 5555H/98H); general CFI mode uses a one-byte entry (55H/98H). Both modes expose standardized geometry and timing data at CFI query addresses (10H–34H), enabling automatic driver configuration in compliant systems.
How does the Auto Low Power mode function in SST39WF1601-90-4I-MBQE during read operations?
In SST39WF1601-90-4I-MBQE, Auto Low Power mode activates automatically after a valid read cycle completes with CE# held low, reducing active read current from ~9 mA to 5 µA. The device exits this mode on any address or control signal transition (e.g., new address setup) with zero access time penalty. It does not engage at power-up until the first address transition occurs.
What are the confirmed erase and program timing values for SST39WF1601-90-4I-MBQE?
The SST39WF1601-90-4I-MBQE specifies typical sector-erase and block-erase times of 36 ms each, chip-erase time of 140 ms, and word-program time of 28 µs. These values are fixed and independent of program/erase cycle count due to SuperFlash cell architecture, eliminating the need for software de-rating over device lifetime.
Can SST39WF1601-90-4I-MBQE be used in systems requiring 1.8 V I/O compatibility without level shifters?
Yes, SST39WF1601-90-4I-MBQE operates natively across 1.65–1.95 V, making it fully compatible with 1.8 V logic families. Its CMOS I/O structure meets JEDEC x16 flash voltage thresholds, and internal VPP generation eliminates external high-voltage supplies - enabling direct connection to 1.8 V microcontrollers without level-shifting circuitry.
