Product details
Overview
SST39VF1682-70-4I-B3KE from Microchip Technology is a 16 Mbit (2M × 8) Multi-Purpose Flash Plus (MPF+) memory IC designed for nonvolatile program, configuration, and data storage in embedded systems. It operates from a single 2.7–3.6 V supply, delivers 70 ns read access time, supports hardware top-block protection (64 KB), and uses SuperFlash® technology for 100,000 program/erase cycles and >100 years data retention. It is commonly used in industrial controllers and firmware-updatable communication modules.
For engineers reviewing the SST39VF1682-70-4I-B3KE datasheet, SST39VF1682-70-4I-B3KE pinout, SST39VF1682-70-4I-B3KE application, or SST39VF1682-70-4I-B3KE equivalent, this page provides verified technical context, JEDEC-compliant x8 interface details, block/sector erase timing, Auto Low Power mode behavior, and real-world design implications for boot code storage and field firmware updates.
Technical Context
The SST39VF1682-70-4I-B3KE implements a JEDEC-standard x8 asynchronous flash interface with latched address/data and CMOS I/O compatibility. Its SuperFlash® split-gate cell architecture enables fixed 7 µs byte-program and uniform 18 ms sector/block-erase times-performance independent of accumulated write cycles.
It features dual write-detection methods (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits), hardware reset (RST#), write protect (WP#) for top 64 KB boot block, and CFI query support. The device enters Auto Low Power mode after valid reads, reducing active current from 9 mA to 3 µA without access penalty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2,097,152 × 8 bits); supports full firmware image or boot loader storage in space-constrained designs. |
| Read Access Time | 70 ns max; enables direct execution (XIP) from flash in microcontroller-based systems without wait states at moderate clock speeds. |
| Supply Voltage | 2.7–3.6 V single supply; compatible with 3.3 V logic domains and eliminates need for separate VPP programming voltage. |
| Endurance | 100,000 program/erase cycles (typical); sufficient for frequent field firmware updates over product lifetime. |
| Data Retention | >100 years; ensures long-term reliability in unpowered storage for industrial and automotive applications. |
| Erase Granularity | Uniform 4 KB sectors and 64 KB blocks; allows precise firmware patching without erasing entire device. |
| Power Consumption | 9 mA active (5 MHz), 3 µA standby/auto-low-power; reduces system-level power budget in always-on edge devices. |
Pinout & Package
Package: 48-ball TFBGA (6 mm × 8 mm, B3K footprint). Pin assignments conform to JEDEC standard x8 flash pinout. WP# enables hardware protection of top 64 KB boot block; RST# provides synchronous hardware reset to Read mode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus; A20 is most significant bit (AMS); selects sector (A12–A20) or block (A16–A20) during erase. |
| DQ0–DQ7 | Data I/O | 8-bit bidirectional data bus; tri-stated when CE# or OE# high; supports latched read/write with status polling on DQ6/DQ7. |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write; controls address/data latch timing with WE#. |
| OE# | Output Enable | Active-low output gate; determines data validity on DQ bus during read; high disables outputs. |
| WE# | Write Enable | Active-low control for program/erase command sequencing; rising edge latches data; falling edge latches address. |
| WP# | Write Protect | Active-low hardware lock for top 64 KB boot block (1F0000H–1FFFFFH); prevents accidental firmware corruption. |
| RST# | Reset | Active-low hardware reset; terminates in-progress operations and forces return to Read mode within TRP. |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; decoupling required per JEDEC guidelines to maintain signal integrity during fast transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows reading or programming other sectors during active erase-critical for real-time systems requiring background firmware updates. |
| Security ID Space | 256-bit user-programmable ID (128-bit factory + 128-bit user); enables secure device authentication and firmware binding. |
| Auto Low Power Mode | Automatically reduces active current to 3 µA after valid read; eliminates need for software-controlled power-down sequences. |
| JEDEC-Compliant Command Set | Supports standard CFI query, software ID entry, and industry-standard erase/program commands-ensures driver compatibility across toolchains. |
| Hardware Block Protection | Top 64 KB boot block protected via WP# pin; prevents overwrite of bootloader during application firmware updates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160CBTI-70G | 16 Mbit x16 interface; 70 ns access; requires 3.0–3.6 V; no Auto Low Power mode; bottom-boot configuration only. | Requires x16 data bus routing; lacks suspend/resume and security ID; not pin-compatible due to different pinout and bus width. | Select only if x16 interface and bottom-boot protection align with existing PCB layout and firmware driver stack. |
| S29AL016J70TFI020 | 16 Mbit x8; 70 ns access; 2.7–3.6 V; supports CFI but no Security ID; top/bottom boot selectable via strapping pins. | No hardware erase-suspend; higher typical active current (12 mA); lacks Auto Low Power mode and RST# pin. | Prefer when CFI compatibility is critical and lower standby power is not required; verify RST# dependency in host reset sequence. |
Compared with MX29LV160CBTI-70G and S29AL016J70TFI020, the SST39VF1682-70-4I-B3KE uniquely combines top-boot hardware protection, erase-suspend capability, Security ID, and Auto Low Power mode-making it optimal for secure, low-power, field-upgradable embedded systems where boot integrity and energy efficiency are design priorities.

FAQ
What is the difference between SST39VF1682-70-4I-B3KE and SST39VF1681?
The SST39VF1682-70-4I-B3KE implements top-block hardware protection (protecting addresses 1F0000H–1FFFFFH), while the SST39VF1681 protects the bottom 64 KB (000000H–00FFFFH). Both share identical density, timing, and command sets-but the WP# pin behavior and protected region differ. SST39VF1682-70-4I-B3KE is selected when bootloader resides in upper memory and must be safeguarded against accidental overwrite during application updates.
Does SST39VF1682-70-4I-B3KE require an external VPP voltage for programming?
No. The SST39VF1682-70-4I-B3KE generates internal VPP for program and erase operations using its 2.7–3.6 V VDD supply-eliminating the need for external high-voltage circuitry. This simplifies board design and improves reliability compared to older flash technologies requiring dedicated VPP pins.
How does the Auto Low Power mode function in SST39VF1682-70-4I-B3KE?
The SST39VF1682-70-4I-B3KE automatically enters Auto Low Power mode after a valid read cycle completes, reducing active current from 9 mA to 3 µA. It exits instantly on any address or control signal transition-no timing penalty or software intervention required. This behavior is inherent to the SST39VF1682-70-4I-B3KE silicon and requires no configuration.
Can SST39VF1682-70-4I-B3KE be used in place of SST39VF1682-70-4C-B3KE?
Yes-the SST39VF1682-70-4I-B3KE is the industrial-grade version (–40°C to +85°C), while SST39VF1682-70-4C-B3KE is commercial grade (0°C to +70°C). All electrical specifications, pinout, and timing are identical except for temperature range. SST39VF1682-70-4I-B3KE is a drop-in replacement in industrial environments where extended thermal operation is required.
What is the purpose of the Security ID feature in SST39VF1682-70-4I-B3KE?
The SST39VF1682-70-4I-B3KE includes a 256-bit Security ID space: 128 bits pre-programmed by SST (factory ID) and 128 bits user-programmable. It enables cryptographic binding of firmware to hardware, anti-cloning, and secure boot verification. Once locked via User Sec ID Program Lock-Out command, the user segment becomes immutable-ensuring persistent device identity in SST39VF1682-70-4I-B3KE deployments.
