Product details
Overview
SST39VF1682-70-4I-EKE 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 features byte-program (7 µs typical) and sector/block/erase capabilities.
For engineers reviewing the SST39VF1682-70-4I-EKE datasheet, SST39VF1682-70-4I-EKE pinout, SST39VF1682-70-4I-EKE application, or SST39VF1682-70-4I-EKE equivalent, key selection considerations include JEDEC-compliant x8 asynchronous interface, SuperFlash® reliability (100,000 write cycles, >100 years retention), TFBGA/TSOP package options, and hardware WP#-controlled top-boot block protection.
Technical Context
The SST39VF1682-70-4I-EKE implements SST's proprietary SuperFlash® technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its architecture supports uniform 4 KB sectors and 64 KB blocks, with dedicated top-block protection activated when WP# is grounded.
It uses standard JEDEC x8 flash command sets-including Software Data Protection (SDP) with three-byte load for programming and six-byte sequences for erase-and provides dual status detection via DQ7 (Data# Polling) and DQ6/DQ2 (Toggle Bits). The device includes RST# for hardware reset and CFI query support for system identification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (2,097,152 × 8 bits); supports full memory mapping for firmware or boot code storage. |
| Read Access Time | 70 ns max; enables direct execution (XIP) from flash in timing-critical microcontroller applications. |
| Supply Voltage | 2.7–3.6 V single supply; compatible with 3.3 V logic domains without level shifting. |
| Endurance | 100,000 program/erase cycles typical; suitable for field-upgradable firmware with moderate update frequency. |
| Data Retention | >100 years at +25°C; ensures long-term reliability in industrial and automotive control modules. |
| Block Protection | Top 64 KB hardware-protected via WP# pin; prevents accidental overwrite of boot code during system updates. |
| Package | 48-ball TFBGA (6 mm × 8 mm); optimized for high-density PCB layouts in space-constrained embedded designs. |
Pinout & Package
Package: 48-ball Thin Fine-Pitch Ball Grid Array (TFBGA), 6 mm × 8 mm, ball pitch 0.5 mm, bottom-side solder balls. Compliant with JEDEC MO-245.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus; A20 is most significant bit (AMS); selects byte location for read/write/erase operations. |
| DQ0–DQ7 | Data I/O | 8-bit bidirectional data bus; latched internally during writes; tri-stated when CE# or OE# is high. |
| CE# | Chip Enable | Active-low chip select; must be low to enable device operation; controls power state transitions. |
| OE# | Output Enable | Active-low output gate; enables data output only when CE# and OE# are both low. |
| WE# | Write Enable | Active-low control for write cycles; latches address/data on falling/rising edges per JEDEC timing. |
| WP# | Write Protect | Active-low top-block protection; grounds to lock top 64 KB (1F0000H–1FFFFFH); internally pulled up if floating. |
| RST# | Reset | Active-low hardware reset; terminates ongoing erase/program and forces return to read mode. |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply and ground; decoupling required per layout guidelines for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows temporary halt of sector/block erase to read or program other locations-critical for real-time firmware updates. |
| Security ID | 256-bit space (128-bit factory SST ID + 128-bit user-programmable); supports secure device authentication and traceability. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access; lowers average power in polling-based systems. |
| CFI Support | JEDEC-standard Common Flash Interface enables automatic device detection and parameter querying by host BIOS/bootloader. |
| Hardware Reset (RST#) | Guarantees recovery from failed write states without requiring power cycle-improves system robustness in unattended operation. |

IC Role / Device Role / Timing Role: JEDEC-compliant x8 flash providing deterministic 70 ns read timing for fast cold-boot performance. Use Value: Industrial temperature grade (-40°C to +85°C) and SuperFlash® reliability ensure consistent startup under thermal stress. |
Use Scenario: Storing multiple firmware images (primary, backup, recovery) in enterprise switches and routers. IC Role / Device Role / Timing Role: Dual-mode erase (sector/block) enables atomic image swaps without full-chip erase delays. Use Value: 18 ms typical block-erase time allows sub-100 ms failover; CFI support simplifies bootloader compatibility across vendor platforms. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1681-70-4I-EKE | Identical architecture and timing, but provides bottom 64 KB hardware block protection instead of top. | Used where boot code resides in lowest memory region (000000H–00FFFFH), not top region. | Select only if board design allocates boot vector to bottom block and WP# routing matches bottom-protection logic. |
| MX29LV160DBTI-70G | 16 Mbit x16/x8 configurable interface; 70 ns access; 3.0–3.6 V supply; no built-in Security ID or Erase-Suspend. | Requires x16/x8 mode configuration; lacks suspend/resume and hardware top-block protection. | Choose when x16 interface is needed or when legacy MX29LV compatibility is mandatory; verify WP# and RST# signal handling. |
Compared with SST39VF1682-70-4I-EKE, SST39VF1681-70-4I-EKE offers identical performance but inverted block protection orientation, while MX29LV160DBTI-70G trades SuperFlash® advantages (fixed timing, suspend/resume, security ID) for broader industry familiarity and x16 flexibility-requiring careful evaluation of boot integrity and update robustness requirements.

FAQ
What is the difference between SST39VF1682-70-4I-EKE and SST39VF1681-70-4I-EKE?
The SST39VF1682-70-4I-EKE implements hardware top-block protection (1F0000H–1FFFFFH), whereas SST39VF1681-70-4I-EKE protects the bottom 64 KB (000000H–00FFFFH). Both share identical density, timing (70 ns), voltage range (2.7–3.6 V), and SuperFlash® reliability specs. Pinout and command set are fully compatible-only WP# behavior and protected address range differ.
Does SST39VF1682-70-4I-EKE support x16 data bus operation?
No. SST39VF1682-70-4I-EKE is strictly an x8 asynchronous parallel interface device (2M × 8 organization). It does not support x16 mode or data bus multiplexing. All read/write/erase operations use DQ0–DQ7 exclusively; no DQ8–DQ15 signals are present or functional.
What package type does SST39VF1682-70-4I-EKE use, and is it RoHS compliant?
SST39VF1682-70-4I-EKE uses a 48-ball TFBGA (6 mm × 8 mm, 0.5 mm pitch) package and is fully RoHS compliant per EU Directive 2011/65/EU. The "4I" in the part number denotes industrial temperature grade (-40°C to +85°C), and "EKE" specifies the TFBGA packaging variant.
How does hardware block protection work on SST39VF1682-70-4I-EKE?
When WP# is driven low, SST39VF1682-70-4I-EKE disables all program and erase operations on the top 64 KB block (1F0000H–1FFFFFH). If WP# is left unconnected, an internal pull-up holds it high, disabling protection. This mechanism operates independently of software commands and remains active even during power-up transients.
Can SST39VF1682-70-4I-EKE be used in systems requiring CFI-compliant flash detection?
Yes. SST39VF1682-70-4I-EKE implements JEDEC-standard Common Flash Interface (CFI). By issuing the CFI Query command (98H at AAAH), the host can read device geometry, timing, and interface descriptors from predefined addresses (e.g., 10H–12H for "QRY", 27H for size), enabling automatic bootloader configuration.
