Product details
Overview
SST39WF1601-90-4C-B3KE 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 90 ns read access time, bottom 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface. It delivers high reliability with 100,000 program/erase cycles and >100 years data retention for embedded firmware storage in industrial controllers.
For engineers reviewing the SST39WF1601-90-4C-B3KE datasheet, SST39WF1601-90-4C-B3KE pinout, SST39WF1601-90-4C-B3KE application, or SST39WF1601-90-4C-B3KE equivalent, this device supports sector/block/chip erase, erase-suspend/resume, security ID programming, and CFI query - critical for secure, field-upgradable boot code storage in space-constrained BGA designs.
Technical Context
The SST39WF1601-90-4C-B3KE implements SuperFlash split-gate technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count - eliminating software de-rating required by conventional flash. Its command-set architecture complies with JEDEC standard pin assignments and supports both SST-specific and general CFI Query modes.
It integrates hardware block protection via WP# pin (protecting bottom 32 KWord boot block), RST# for hardware reset to read mode, and dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits) for precise end-of-write verification during Word-Program, Sector-Erase, Block-Erase, and Chip-Erase operations.
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 | 90 ns - enables direct execution (XIP) from flash at up to ~11 MHz system bus frequency. |
| Supply Voltage | 1.65–1.95 V - compatible with low-voltage SoC I/O domains and eliminates level-shifting in 1.8 V systems. |
| Endurance | 100,000 program/erase cycles - sufficient for frequent field updates in industrial HMI or gateway firmware. |
| Data Retention | >100 years - ensures long-term reliability without refresh in unpowered storage applications. |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) - enables fine-grained update partitioning for OTA firmware. |
| Security ID | 256-bit (128-bit factory + 128-bit user programmable) - provides unique device identity and tamper-resistant key 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 | 16-bit address bus (A0–A15) + 4 MSB (A16–A19) for sector/block selection; AMS = A19 per JEDEC CFI. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; tri-stated when CE# or OE# high; latched on WE#/CE# edges during write. |
| 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; must be low with CE# for valid read output. |
| WE# | Write Enable | Active-low write control; latches address/data on falling/rising edge per JEDEC timing; initiates internal program/erase. |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block (000000H–007FFFH); floating = unprotected. |
| 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; internally generates VPP for erase/program - no external high-voltage source needed. |
| VSS | Ground | Reference ground for all signals; two dedicated VSS balls ensure stable low-impedance return path. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Fixed 28 µs word-program and 36 ms sector/block-erase times across full lifetime - eliminates dynamic timing margining in firmware drivers. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid access - cuts idle power by >99% in polling-based boot loaders. |
| Erase-Suspend/Resume | Allows real-time read/program of non-suspended sectors during erase - enables concurrent firmware validation and update staging. |
| Hardware Block Protection | Bottom 32 KWord (000000H–007FFFH) locked when WP# = low - prevents accidental overwrite of bootloader during application updates. |
| CFI & Security ID Support | JEDEC CFI Query (SST and general modes) + 256-bit Security ID (factory/user segments) - enables automated part identification and cryptographic binding. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W29N01GV | 1 Gbit NAND flash (not x16 parallel); requires ECC and wear-leveling controller; no hardware block protection or CFI. | Higher density but incompatible interface - requires redesign of memory controller and firmware driver stack. | Select only if migrating to NAND-based architecture with dedicated controller; not drop-in for SST39WF1601-90-4C-B3KE. |
| Macronix MX29LV160ET | 16 Mbit x16 parallel NOR; 3.0 V supply (not 1.8 V); 100 ns access; top-boot block protection only; no Security ID or Auto Low Power mode. | Compatible pinout but voltage mismatch - requires level-shifting or board revision; lacks suspend/resume and low-power features. | Consider for legacy 3 V systems where 1.8 V operation and advanced power management are not required. |
Compared with Winbond W29N01GV and Macronix MX29LV160ET, the SST39WF1601-90-4C-B3KE uniquely combines 1.8 V operation, bottom-boot hardware protection, erase-suspend, and integrated Security ID - making it optimal for secure, low-power, field-upgradable embedded firmware where pin compatibility and feature parity matter.

FAQ
What is the exact memory organization of the SST39WF1601-90-4C-B3KE?
The SST39WF1601-90-4C-B3KE is organized as 1,048,576 words × 16 bits (1M × 16), totaling 16 Mbit. It features uniform 2 KWord (4 KB) sectors and 32 KWord (64 KB) blocks. The bottom 32 KWord (addresses 000000H–007FFFH) is hardware-protected when WP# is asserted low. This structure is confirmed in the official datasheet Section "PRODUCT DESCRIPTION" and Table 2.
Does the SST39WF1601-90-4C-B3KE support both CFI Query modes?
Yes, the SST39WF1601-90-4C-B3KE supports both SST-specific CFI Query mode (entered via three-byte sequence 5555H/AAH → 2AAAH/55H → 5555H/98H) and general JEDEC CFI Query mode (entered via one-byte sequence 55H/98H). Both modes allow reading device geometry, timing, and interface information from CFI address space, as detailed in Section "Common Flash Memory Interface (CFI)".
How does hardware block protection work on the SST39WF1601-90-4C-B3KE?
The SST39WF1601-90-4C-B3KE implements bottom-block hardware protection: when WP# is driven low, program and erase operations are disabled for the bottom 32 KWord (000000H–007FFFH). If WP# is left floating, an internal pull-up holds it high, leaving the boot block unprotected. This behavior is explicitly defined in the "Hardware Block Protection" section and Table 2 of the datasheet.
What are the valid status detection methods during Word-Program on the SST39WF1601-90-4C-B3KE?
The SST39WF1601-90-4C-B3KE supports two end-of-write detection methods during Word-Program: Data# Polling (DQ7 toggles until completion, then outputs true data) and Toggle Bit (DQ6 toggles until completion, then stops). DQ7 is valid after the rising edge of the fourth WE# pulse; DQ6 is valid after the same edge. These are specified in Section "Write Operation Status Detection" and Table 1.
Is the SST39WF1601-90-4C-B3KE compatible with 1.8 V-only systems?
Yes, the SST39WF1601-90-4C-B3KE operates across 1.65–1.95 V, making it fully compatible with standard 1.8 V ±10% power rails. Its CMOS I/O is compliant with 1.8 V logic levels, and internal VPP generation eliminates need for external high-voltage supplies - confirmed in "Single Voltage Read and Write Operations" and "Absolute Maximum Stress Ratings" sections.
