Product details
Overview
SST39WF1601-90-4I-B3KE-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 90 ns read access time, bottom 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface - used for firmware storage in industrial microcontroller boot loaders.
For engineers reviewing the SST39WF1601-90-4I-B3KE-T datasheet, SST39WF1601-90-4I-B3KE-T pinout, SST39WF1601-90-4I-B3KE-T application, or SST39WF1601-90-4I-B3KE-T equivalent, key selection considerations include its 1.65–1.95 V single-supply operation, 100,000-cycle endurance, Auto Low Power mode (5 µA), sector/block/chip erase capabilities, and bottom-boot-block protection architecture.
Technical Context
The SST39WF1601-90-4I-B3KE-T 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 Security ID programming.
Its operation relies on latched address/data with CE#/OE#/WE# control logic, hardware reset (RST#), write protect (WP#) for bottom 32 KWord boot block, and dual status detection via DQ7 (Data# Polling) and DQ6/DQ2 (Toggle Bits). Erase-suspend/resume functionality enables concurrent read/program during background erase.
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 | 90 ns - enables direct execution (XIP) from flash in systems with ≤11 MHz bus timing budget. |
| 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 firmware updates over 10+ years in industrial controllers. |
| Data Retention | >100 years - ensures long-term reliability without refresh in unpowered storage applications. |
| Erase Granularity | 2 KWord sectors / 32 KWord blocks / full chip - allows fine-grained update of bootloader, config, or application partitions. |
| Protection Scheme | Hardware bottom block protection (000000H–007FFFH) + software data protection - prevents accidental overwrite of critical boot code. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, ball pitch 0.5 mm), RoHS-compliant, non-Pb.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 16-bit address bus (A0–A15) + 4 MSBs (A16–A19) for sector/block selection; AMS = A19 per JEDEC CFI. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with tri-state outputs controlled by CE# and OE#; supports latched read/write transfers. |
| CE# | Chip Enable | Active-low device select; must be low for all write operations and valid reads; high = standby (40 µA). |
| OE# | Output Enable | Active-low output gate; controls data bus drive; high or floating places outputs in high-impedance state. |
| WE# | Write Enable | Active-low write strobe; latches address on falling edge, data on rising edge; required for all command sequences. |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block (000000H–007FFFH); grounded = protected. |
| RST# | Reset | Active-low hardware reset; terminates ongoing erase/program and forces return to read mode within TRP. |
| VDD | Power Supply | 1.65–1.95 V core supply; internal VPP generation eliminates external high-voltage charge pump. |
| VSS | Ground | Primary ground reference for all I/O and core logic; two dedicated VSS balls ensure low-noise operation. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Fixed 28 µs word-program and 36 ms sector/block-erase times across full lifetime - eliminates software de-rating for aging. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid access - cuts average power in burst-read embedded systems. |
| Erase-Suspend/Resume | Pauses background erase to allow read from any unprotected sector or program into non-suspended blocks - enables real-time firmware patching. |
| Security ID Space | 256-bit factory/user programmable ID (128-bit locked SST ID + 128-bit customer-programmable segment) - supports secure boot authentication. |
| JEDEC CFI Compliance | Supports both SST-specific and general CFI Query modes (via 5555H/98H or 55H/98H) - enables auto-detection in generic flash programmers. |

FAQ
What is the guaranteed read access time for SST39WF1601-90-4I-B3KE-T?
The SST39WF1601-90-4I-B3KE-T has a guaranteed maximum read access time of 90 ns under standard operating conditions (VDD = 1.65–1.95 V, TA = -40°C to +85°C). This specification is validated across the full industrial temperature range and ensures deterministic timing for MCU bus interfacing without wait states in most 16-bit architectures.
Does SST39WF1601-90-4I-B3KE-T support hardware write protection for the boot sector?
Yes, the SST39WF1601-90-4I-B3KE-T implements bottom hardware block protection: when WP# is driven low, the bottom 32 KWord (000000H–007FFFH) is locked against program and erase operations. This protects bootloader code from accidental corruption during firmware updates or system glitches.
What package type is used for SST39WF1601-90-4I-B3KE-T?
The SST39WF1601-90-4I-B3KE-T is packaged in a 48-ball WFBGA with 4 mm × 6 mm footprint and 0.5 mm ball pitch. This compact, RoHS-compliant package supports high-density PCB layouts and is optimized for automated surface-mount assembly in industrial and medical electronics.
How does SST39WF1601-90-4I-B3KE-T indicate completion of a program or erase operation?
The SST39WF1601-90-4I-B3KE-T provides two hardware-supported status detection methods: Data# Polling (DQ7 toggles until completion, then returns true data) and Toggle Bit (DQ6 toggles during operation, stops when complete). Both are accessible via standard read cycles and require no external polling hardware.
Is SST39WF1601-90-4I-B3KE-T compatible with JEDEC-standard flash command sets?
Yes, the SST39WF1601-90-4I-B3KE-T fully complies with JEDEC Standard JESD21-C for x16 flash pin assignments and command definitions. It supports both SST-specific and general CFI Query modes, Software ID Entry/Exit, and industry-standard sector/block/chip erase command sequences.
