Product details
Overview
SST39VF1601-70-4C-B3KE-T from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC designed for embedded code storage and firmware update applications. It operates from a single 2.7–3.6 V supply, delivers 70 ns read access time, supports hardware bottom-block protection (bottom 32 KWord), and features sector/block/chip erase with erase-suspend/resume capability.
For engineers reviewing the SST39VF1601-70-4C-B3KE-T datasheet, SST39VF1601-70-4C-B3KE-T pinout, SST39VF1601-70-4C-B3KE-T application, or SST39VF1601-70-4C-B3KE-T equivalent, key selection criteria include boot-block protection configuration, TSOP-48 package compatibility, JEDEC-standard x16 asynchronous interface timing, and SuperFlash endurance/reliability metrics.
Technical Context
The SST39VF1601-70-4C-B3KE-T 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 command-set architecture conforms to JEDEC standard pinouts and supports Software Data Protection via six-byte sequences for erase and three-byte sequences for program.
It integrates hardware block protection tied to WP# for bottom 32 KWord (000000H–007FFFH), RST# for hardware reset to read mode, and dual status detection (DQ7 Data# Polling and DQ6 Toggle Bit) for write completion monitoring without polling overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words) - supports full firmware image storage in space-constrained designs |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) in microcontroller systems with ≤14 MHz bus timing |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V logic domains and eliminates need for dedicated VPP programming voltage |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years in industrial control applications |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage for medical or aerospace black-box logging |
| Erase Granularity | Uniform 2 KWord sectors (8 KB) and 32 KWord blocks (64 KB) - allows selective firmware patching without full chip reprogramming |
| Protection Scheme | Hardware bottom-block protection (WP#-enabled) + Software Data Protection - prevents accidental corruption of boot code during power transitions |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm, Type I, standard pinout). Pin assignments conform to JEDEC MO-142AC and are validated for SST39VF1601/1602 family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | A0–A18 used for 1M×16 addressing; A19 is MSB for SST39VF1601 (not connected in SST39VF1602) |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus with internal latching; 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 during read; high = high-Z |
| WE# | Write Enable | Controls latching of address/data during program/erase; falling edge latches address, rising edge latches data |
| WP# | Write Protect | Hardware lock for bottom 32 KWord (000000H–007FFFH); grounded = protection enabled |
| RST# | Reset | Hardware abort of in-progress erase/program; forces return to read mode within TRP (≤100 ns) |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; decoupling required per JEDEC layout guidelines for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows real-time read access to non-suspended sectors during active erase - critical for interrupt-driven firmware update routines |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts standby power in battery-backed systems |
| Security ID Space | 256-bit factory + user programmable ID (128 + 128 bits) - enables secure device authentication and firmware binding |
| CFI Support | Common Flash Interface compliant - enables automatic driver detection and configuration in Linux/BSP environments |
| SuperFlash Reliability | Fixed 18 ms sector/block erase and 7 µs word-program times - eliminates software de-rating across product lifetime |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C | Successor with enhanced ESD rating (4 kV HBM) and updated process; identical pinout and command set | Recommended for new designs per Microchip notice; same boot-block protection and timing | Select SST39VF1601C for production ramps requiring extended lifecycle support and improved robustness |
| MX29LV160ETTI-70G | 16 Mbit x16 flash with 70 ns access; different command set (AMD-style), no erase-suspend, no Security ID | Lacks suspend/resume and hardware boot protection; requires modified driver stack | Use only if legacy AMD-compatible systems require drop-in replacement without firmware changes |
Compared with SST39VF1601C, the SST39VF1601-70-4C-B3KE-T lacks updated ESD specs but retains identical functional behavior and timing; versus MX29LV160ETTI-70G, it offers superior system-level flexibility via erase-suspend and integrated security features at the cost of non-drop-in software compatibility.

FAQ
What does the "B3KE-T" suffix indicate in SST39VF1601-70-4C-B3KE-T?
The "B3KE-T" suffix denotes a specific packaging and marking variant: "B3K" indicates 48-ball TFBGA (6 mm × 8 mm) package with lead-free (Pb-free) finish and RoHS compliance; "E" specifies industrial temperature range (–40°C to +85°C); and "T" signifies tape-and-reel packaging. However, per DS25028A Figure 3, SST39VF1601-70-4C-B3KE-T uses the 48-lead TSOP package-not TFBGA-confirming "B3K" here references the TSOP-48 mechanical outline (B3K = standard TSOP-48 footprint per SST documentation), not ball grid array. The SST39VF1601-70-4C-B3KE-T is therefore a TSOP-48 device rated for industrial temperature and shipped in tape-and-reel.
Does SST39VF1601-70-4C-B3KE-T support true x16 parallel interface operation?
Yes, the SST39VF1601-70-4C-B3KE-T implements a true x16 asynchronous interface with DQ0–DQ15 as fully bidirectional data lines. It supports byte-wide access only when externally masked; all internal operations (read, program, erase) execute on 16-bit words. The device conforms to JEDEC standard pinouts for x16 memories, and Table 9 confirms "Flash Device Interface description: 0001H = x16-only asynchronous interface", validating native 16-bit bus operation without multiplexing or internal width conversion.
How is hardware block protection implemented on SST39VF1601-70-4C-B3KE-T?
The SST39VF1601-70-4C-B3KE-T implements bottom-block hardware protection: when WP# is driven low, program and erase operations are disabled for the bottom 32 KWord (64 KB) region (address range 000000H–007FFFH), preserving boot code. This protection is active regardless of software state and persists through power cycles. Per Table 3 and datasheet Section 9, SST39VF1601/3201 variants exclusively support bottom-block protection, distinguishing them from SST39VF1602/3202 top-block variants. Floating WP# defaults to high via internal pull-up, disabling protection.
Can SST39VF1601-70-4C-B3KE-T be used in systems requiring Common Flash Interface (CFI) compliance?
Yes, the SST39VF1601-70-4C-B3KE-T fully supports CFI per JEDEC JESD68. Entering CFI Query mode requires the three-byte command sequence (5555H/AAH → 2AAAH/55H → 5555H/98H), after which CFI data (Tables 7–10) can be read to auto-detect geometry, timing, and command set. This enables OS-agnostic flash drivers (e.g., Linux MTD) to configure correctly without hard-coded parameters - a key advantage over non-CFI flashes like older AMD or Intel parts. CFI exit uses the same 5555H/F0H command as Software ID Exit.
Is SST39VF1601-70-4C-B3KE-T still recommended for new designs?
No - Microchip explicitly marks SST39VF1601-70-4C-B3KE-T as "Not Recommended for New Designs" in DS25028A, advising migration to SST39VF1601C for new projects. The SST39VF1601C offers identical functionality, pinout, and timing but with enhanced ESD robustness (4 kV HBM vs. unspecified for original) and continued long-term supply assurance. SST39VF1601-70-4C-B3KE-T remains viable for legacy design refreshes and repair programs where form-fit-function match is mandatory, supported by Aetrix Electronics' continuity management.
