Product details
Overview
SST39VF1682-70-4C-EKE from Microchip Technology is a 16 Mbit (2M × 8) Multi-Purpose Flash Plus memory IC with JEDEC-standard x8 asynchronous interface, 70 ns read access time, single 2.7–3.6 V supply operation, and top 64 KByte hardware block protection. It serves as nonvolatile program/data storage in embedded controllers, BIOS firmware, and industrial HMI systems requiring field-upgradable code.
For engineers reviewing the SST39VF1682-70-4C-EKE datasheet, SST39VF1682-70-4C-EKE pinout, SST39VF1682-70-4C-EKE application, or SST39VF1682-70-4C-EKE equivalent, key selection considerations include boot-block protection direction (top vs. bottom), TSOP-48 vs. TFBGA-48 package compatibility, sector/block erase timing consistency, SuperFlash® energy efficiency, and hardware reset (RST#) integration for system recovery.
Technical Context
The SST39VF1682-70-4C-EKE implements SST's proprietary SuperFlash® technology with split-gate cell architecture and thick-oxide tunneling injector, enabling fixed 7 µs byte-program and 18 ms sector/block-erase times independent of cycle count. Its command set complies with JEDEC standard pinouts and includes software data protection via six-byte sequences for erase and three-byte sequences for program.
Hardware features include dedicated WP# for top 64 KByte boot-block protection, RST# for hard reset to read mode, and dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits) for write completion monitoring. The device supports CFI query mode and 256-bit Security ID with factory-programmed SST segment and user-programmable segment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2,097,152 × 8 bits); supports full firmware image storage for mid-complexity microcontrollers. |
| Read Access Time | 70 ns; enables direct execution from flash (XIP) in systems with ≤14 MHz bus timing budgets. |
| Supply Voltage | 2.7–3.6 V; compatible with 3.3 V logic rails and tolerant of brown-out conditions down to 2.7 V. |
| Endurance | 100,000 program/erase cycles; sufficient for firmware update cycles over 10+ years in industrial control applications. |
| Data Retention | >100 years; ensures long-term reliability without refresh in unpowered storage scenarios. |
| Block Protection | Top 64 KByte (0x1F0000–0x1FFFFF); prevents accidental overwrite of boot code during field updates. |
| Package | 48-lead TSOP (12 mm × 20 mm); surface-mount compatible with standard reflow profiles and legacy PCB footprints. |
Pinout & Package
48-lead TSOP (Thin Small Outline Package), standard pinout per JEDEC MO-142AC, 12 mm × 20 mm body, die-up orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus; A20 is most significant bit (AMS), used to select sectors (A12–A20) or blocks (A16–A20). |
| DQ0–DQ7 | Data I/O | 8-bit bidirectional data bus; latched internally during writes; tri-stated when CE# or OE# high. |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 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 outputs. |
| WE# | Write Enable | Active-low write control; latches address/data on falling/rising edges per JEDEC command protocol. |
| WP# | Write Protect | Active-low top boot-block lock; grounded to prevent program/erase of 0x1F0000–0x1FFFFF region. |
| RST# | Hardware Reset | Active-low reset input; forces immediate return to read mode, terminating any in-progress erase/program. |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; decoupling required within 10 mm of pins per JEDEC layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Fixed 7 µs byte-program and 18 ms sector/block-erase times across full lifecycle-no software de-rating needed. |
| Erase-Suspend/Resume | Allows reading or programming non-suspended sectors during active erase, enabling real-time system responsiveness. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access, cutting power by >99% during idle polling. |
| Security ID Space | 256-bit ID (128-bit SST + 128-bit user); factory-locked SST segment prevents cloning; user segment supports secure provisioning. |
| JEDEC CFI Support | Standardized geometry and timing query capability enables automatic driver configuration in bootloader environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1681-70-4C-EKE | Identical specs except bottom 64 KByte hardware block protection (0x000000–0x00FFFF) instead of top. | Used where boot code resides at lowest address; incompatible for top-boot designs without PCB change. | Select only if board layout and firmware address map align with bottom-boot architecture. |
| MX29LV160ETTI-70G | 16 Mbit x16/x8 configurable interface; 70 ns access; 3.0–3.6 V supply; no RST# pin; different command set and CFI structure. | Lacks hardware reset and erase-suspend; requires driver adaptation; not drop-in for RST#-dependent recovery schemes. | Consider for cost-sensitive designs where RST# and suspend/resume are unused; verify command sequence compatibility. |
Compared with SST39VF1682-70-4C-EKE, SST39VF1681-70-4C-EKE offers identical performance but inverted boot-block location, while MX29LV160ETTI-70G sacrifices RST# and erase-suspend for broader vendor availability-requiring firmware and layout review before substitution.

FAQ
What is the boot-block protection scheme implemented in SST39VF1682-70-4C-EKE?
The SST39VF1682-70-4C-EKE implements top 64 KByte hardware block protection, covering address range 0x1F0000–0x1FFFFF. When the WP# pin is grounded, program and erase operations to this region are disabled. This ensures critical boot code remains intact during firmware updates. The SST39VF1682-70-4C-EKE differs from SST39VF1681 in this protection direction, which is fixed per part number and cannot be reconfigured.
Does SST39VF1682-70-4C-EKE support simultaneous read and erase operations?
Yes, SST39VF1682-70-4C-EKE supports Erase-Suspend/Erase-Resume functionality. During an active sector or block erase, issuing the B0H command suspends the operation, allowing reads from any non-suspended sector or byte-programming into unprotected regions. The SST39VF1682-70-4C-EKE exits suspend mode within 20 µs and resumes erase upon receipt of the 30H resume command.
What are the valid voltage ranges and current consumption values for SST39VF1682-70-4C-EKE during active read?
SST39VF1682-70-4C-EKE operates from 2.7 V to 3.6 V. Typical active read current is 9 mA at 5 MHz, with maximum specified at 18 mA under worst-case conditions (VDD max, f = 5 MHz). Auto Low Power mode reduces this to 3 µA after valid read access, and standby current is rated at 20 µA max.
How is end-of-write detection implemented in SST39VF1682-70-4C-EKE?
SST39VF1682-70-4C-EKE provides two hardware-supported methods: Data# Polling (DQ7 toggles complement until completion, then returns true data) and Toggle Bits (DQ6 toggles during internal operation, stops when complete). For Security ID writes, only Toggle Bit detection is valid. Both methods require polling after the rising edge of the fourth (program) or sixth (erase) WE# pulse.
Is SST39VF1682-70-4C-EKE pin-compatible with other 48-lead TSOP flash devices?
SST39VF1682-70-4C-EKE conforms to JEDEC standard x8 flash pinouts, matching signal assignments (A0–A20, DQ0–DQ7, CE#/OE#/WE#, WP#, RST#, VDD/VSS) for 48-lead TSOP. However, command sets, timing parameters, and feature enablement (e.g., RST# behavior, erase-suspend) differ across vendors. Direct replacement requires validation of firmware command sequences and timing margins-not just pin alignment.
