Product details

Overview

SST39VF1682-70-4I-B3KE-T from Microchip Technology is a 16 Mbit (2M × 8) Multi-Purpose Flash Plus memory IC with single-supply 2.7–3.6 V operation, 70 ns read access time, and top 64 KByte hardware block protection. It implements SuperFlash® technology for high reliability in embedded firmware storage applications requiring field-upgradable code or configuration data.

For engineers reviewing the SST39VF1682-70-4I-B3KE-T datasheet, SST39VF1682-70-4I-B3KE-T pinout, SST39VF1682-70-4I-B3KE-T application, or SST39VF1682-70-4I-B3KE-T equivalent, key selection considerations include JEDEC x8-compatible timing, sector/block/chip erase flexibility, Auto Low Power mode (3 µA), and hardware WP#-based top-boot protection - all validated for industrial temperature range (−40°C to +85°C).

Technical Context

The SST39VF1682-70-4I-B3KE-T uses SST's proprietary split-gate SuperFlash® cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its command-set complies fully with JEDEC standard x8 flash pinouts and protocols, including CFI Query support and Software Data Protection (SDP) with three-byte unlock sequences.

It supports Byte-Program (7 µs typical), Sector-Erase (4 KByte), Block-Erase (64 KByte), Chip-Erase (40 ms typical), and Erase-Suspend/Resume functionality. The device features dual status detection via DQ7 (Data# Polling) and DQ6/DQ2 (Toggle Bits), and integrates RST# for hardware reset and WP# for top-block hardware write protection.

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 max; enables direct execution (XIP) from flash in systems with ≤14 MHz bus timing budgets.
Supply Voltage	2.7–3.6 V single supply; compatible with 3.3 V logic rails without level-shifting.
Endurance	100,000 program/erase cycles typical; sufficient for firmware update cycles over 10+ years in industrial deployments.
Data Retention	>100 years at +85°C; ensures long-term integrity of boot code and calibration data without refresh.
Erase Granularity	Uniform 4 KByte sectors and 64 KByte blocks; allows selective firmware patching without full chip reprogramming.
Standby Current	3 µA typical (Auto Low Power mode); reduces system power during idle periods in battery-backed or energy-sensitive designs.

Pinout & Package

Package: 48-ball TFBGA (6 mm × 8 mm, 0.8 mm pitch), RoHS-compliant, industrial-grade moisture sensitivity level (MSL) 3.

Pin/Terminal	Circuit Role	Design Meaning
A0–A20	Address Inputs	A20 is most significant address; AMS = A20 per JEDEC x8 mapping; selects sector (A12–A20) or block (A16–A20).
DQ0–DQ7	Data I/O	Bi-directional 8-bit bus; latched internally during writes; tri-stated when CE# or OE# high.
CE#	Chip Enable	Active-low device select; must be low for all write/erase operations and valid reads.
OE#	Output Enable	Active-low output gate; controls data bus drive; high disables outputs to reduce noise and leakage.
WE#	Write Enable	Active-low control for byte-program and command latching; timing-critical for SDP sequence validity.
WP#	Write Protect	Active-low hardware lock for top 64 KByte boot block (0x1F0000–0x1FFFFF); prevents accidental firmware corruption.
RST#	Reset Input	Active-low hardware abort; terminates ongoing erase/program and forces return to read mode within TRP.
VDD / VSS	Power / Ground	Single 2.7–3.6 V supply; decoupling required per JEDEC layout guidelines to maintain 70 ns timing stability.

Key Features

Feature	Design Value
SuperFlash® Technology	Split-gate cell with fixed 7 µs byte-program and 18 ms sector/block-erase times across full lifecycle - eliminates software de-rating.
Hardware Block Protection	Top 64 KByte boot block (0x1F0000–0x1FFFFF) locked when WP# = low; prevents overwrite of bootloader during field updates.
Erase-Suspend/Resume	Allows real-time read access to non-suspended sectors during erase; enables background firmware validation while erasing adjacent blocks.
Security ID Space	256-bit space (128-bit factory-assigned SST ID + 128-bit user-programmable segment) for device authentication or traceability.
CFI Query Support	JEDEC-standard Common Flash Interface enables automatic driver detection and runtime parameter extraction in OS/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
SST39VF1681-70-4I-B3KE-T	Identical architecture and timing, but implements bottom 64 KByte hardware block protection (0x000000–0x00FFFF) instead of top-block.	Suitable where bootloader resides in lowest memory region; incompatible if system expects top-boot vector table layout.	Select only if board layout and firmware linker script assign boot code to bottom 64 KByte - not a drop-in replacement.
MX29LV160ETTI-70G	16 Mbit x16/x8 configurable interface; 70 ns access; requires VPP = 12 V for programming (vs. internal VPP generation in SST39VF1682).	Supports wider data bus modes but lacks Auto Low Power mode and Erase-Suspend; higher VPP complexity increases BOM cost.	Prefer SST39VF1682-70-4I-B3KE-T for 3.3 V-only systems needing ultra-low standby power and suspend/resume capability.

Compared with SST39VF1681-70-4I-B3KE-T, this part offers top-boot protection essential for modern vector-table-first boot architectures; versus MX29LV160ETTI-70G, it eliminates external VPP circuitry and delivers 3 µA standby via Auto Low Power - critical for thermally constrained or battery-assisted infotainment modules.

FAQ

What is the guaranteed operating temperature range for SST39VF1682-70-4I-B3KE-T?

The SST39VF1682-70-4I-B3KE-T is rated for industrial temperature operation from −40°C to +85°C, as confirmed in Table 10 of the DS25040A datasheet. This range applies to all DC and AC specifications including 70 ns read access, 100,000-cycle endurance, and 3 µA Auto Low Power mode - making SST39VF1682-70-4I-B3KE-T suitable for deployment in uncontrolled ambient environments such as factory floors or vehicle cabins.

Does SST39VF1682-70-4I-B3KE-T require an external VPP voltage for programming?

No, SST39VF1682-70-4I-B3KE-T generates internal VPP during program and erase operations and operates from a single 2.7–3.6 V supply. This eliminates the need for external high-voltage circuitry, simplifying PCB layout and reducing BOM cost - a key differentiator from older flash families like the MX29LV series that require 12 V VPP. All write timing and voltage regulation are handled on-die in SST39VF1682-70-4I-B3KE-T.

How does hardware block protection work on SST39VF1682-70-4I-B3KE-T?

SST39VF1682-70-4I-B3KE-T implements top 64 KByte hardware block protection: when WP# is driven low, program and erase operations are disabled for addresses 0x1F0000–0x1FFFFF. This protects the boot sector containing reset vectors and initial firmware. If WP# is left floating, an internal pull-up holds it high, disabling protection. SST39VF1682-70-4I-B3KE-T does not support bottom-block protection - that function is exclusive to the SST39VF1681 variant.

Can SST39VF1682-70-4I-B3KE-T be used in systems requiring JEDEC-standard CFI support?

Yes, SST39VF1682-70-4I-B3KE-T fully implements the Common Flash Interface (CFI) per JEDEC JESD68. Executing the three-byte CFI Query command (0x98 at address 0x5555) enables reading device geometry, timing, and command-set descriptors from dedicated CFI address space (Tables 7–9). This allows generic flash drivers to auto-configure for SST39VF1682-70-4I-B3KE-T without hardcoded parameters.

What is the purpose of the RST# pin on SST39VF1682-70-4I-B3KE-T?

The RST# pin on SST39VF1682-70-4I-B3KE-T provides hardware-initiated abort and recovery: holding RST# low for ≥TRP (100 ns min) terminates any active program or erase operation and forces immediate return to Read mode. After RST# is released, a minimum TRHR (100 ns) delay is required before valid reads resume. This enables safe power-cycle recovery and watchdog-triggered firmware reload - a critical feature for SST39VF1682-70-4I-B3KE-T in mission-critical embedded systems.
