Product details
Overview
SST39VF1601-70-4I-B3KE-T from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with 70 ns read access time, single 2.7–3.6 V supply operation, and bottom 32 KWord hardware block protection. It supports sector-erase (2 KWord), block-erase (32 KWord), chip-erase, and erase-suspend/resume functions, and is used in embedded firmware storage for industrial controllers and legacy communication modules.
For engineers reviewing the SST39VF1601-70-4I-B3KE-T datasheet, SST39VF1601-70-4I-B3KE-T pinout, SST39VF1601-70-4I-B3KE-T application, or SST39VF1601-70-4I-B3KE-T equivalent, key selection considerations include boot-block protection direction (bottom), TSOP-48 package compatibility, JEDEC-standard x16 asynchronous interface timing, and SuperFlash endurance/reliability trade-offs versus newer alternatives.
Technical Context
The SST39VF1601-70-4I-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. It uses standard JEDEC x16 flash command sets-including six-byte sequences for sector/block/chip erase-and supports both Data# Polling (DQ7) and Toggle Bit (DQ6/DQ2) status detection.
Hardware protection is implemented via WP# pin assertion to lock the bottom 32 KWord boot block (000000H–007FFFH), while RST# provides hardware reset to Read mode. The device operates in 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 (1M × 16 organization), providing 2 MB of nonvolatile storage space |
| Read Access Time | 70 ns - determines maximum sustained read throughput in synchronous bus systems |
| Supply Voltage | 2.7–3.6 V - enables direct interfacing with 3.3 V logic without level shifting |
| Endurance | 100,000 program/erase cycles - defines field-replaceable firmware update lifetime |
| Data Retention | >100 years - ensures long-term data integrity in unpowered storage applications |
| Erase Granularity | Uniform 2 KWord sectors and 32 KWord blocks - enables fine-grained firmware patching and recovery partitioning |
| Protection Scheme | Hardware bottom boot-block (32 KWord) + software data protection - prevents accidental overwrite of bootloader code |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, standard JEDEC x16 flash footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | A0–A18 used for 1M×16 addressing; A19 is MSB and required for full address decoding |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus with internal latching and tri-state control via CE#/OE# |
| CE# | Chip Enable | Active-low chip select; device enters standby when high |
| OE# | Output Enable | Active-low output gate; controls data bus tristate during reads |
| WE# | Write Enable | Controls latching of addresses/data during program/erase command sequences |
| WP# | Write Protect | Grounding locks bottom 32 KWord boot block against erase/program operations |
| RST# | Reset | Hardware reset input; forces return to Read mode and aborts in-progress operations |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; no separate VPP required due to on-chip charge pump |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash cell architecture | Split-gate + thick-oxide injector enables fixed 7 µs word-program and 18 ms erase times across full lifecycle |
| Erase-suspend/resume | Allows temporary read access or programming in non-suspended sectors during active erase, improving system responsiveness |
| Security ID space | 256-bit factory/user programmable ID (128+128 bits), locked per-user segment prevents tampering |
| CFI support | Standard Common Flash Interface enables automatic driver detection and configuration in BIOS/bootloader environments |
| Auto Low Power mode | Reduces active read current from 9 mA to 3 µA after valid access-no software intervention required |

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 variant with enhanced ESD rating (4 kV HBM) and updated qualification per AEC-Q100 Grade 3; identical pinout and command set | Required for new automotive designs; supports extended temperature range (–40°C to +105°C) vs. SST39VF1601-70-4I-B3KE-T (–40°C to +85°C) | Select SST39VF1601C for new production where automotive qualification or higher ESD robustness is mandated. |
| MX29LV160DBTI-70G | 16 Mbit x16 flash with 70 ns access, but uses different command set (Spansion CFI v1.1), no erase-suspend, and requires VPP = 12 V for program/erase | Lacks hardware boot-block direction control; bottom protection must be managed via software lock bits only | Choose MX29LV160DBTI-70G only if legacy Spansion ecosystem compatibility is required and erase-suspend is not needed. |
Compared with SST39VF1601C, the SST39VF1601-70-4I-B3KE-T lacks AEC-Q100 qualification and has lower ESD immunity, making it suitable for industrial/commercial use only; compared with MX29LV160DBTI-70G, it offers superior flexibility with hardware WP#-based bottom-block protection and integrated VPP generation eliminating external voltage circuitry.

FAQ
What is the memory organization and total capacity of the SST39VF1601-70-4I-B3KE-T?
The SST39VF1601-70-4I-B3KE-T is organized as 1M × 16, delivering 16 Mbit (2 MB) of nonvolatile storage. Its address space spans A0–A18 for main memory, with A19 used as the most significant bit in command sequences. This configuration supports direct connection to 16-bit microprocessor buses without data multiplexing or glue logic.
Does the SST39VF1601-70-4I-B3KE-T require an external VPP voltage for programming or erasing?
No, the SST39VF1601-70-4I-B3KE-T does not require an external VPP voltage. It integrates an on-chip charge pump that generates the necessary high-voltage programming/erasing signals from the single 2.7–3.6 V VDD supply. This eliminates the need for external high-voltage circuitry and simplifies board design.
How does hardware block protection work on the SST39VF1601-70-4I-B3KE-T?
The SST39VF1601-70-4I-B3KE-T implements bottom 32 KWord hardware block protection: when WP# is driven low, program and erase operations are disabled for addresses 000000H–007FFFH. This protects bootloader code from accidental overwrite. If WP# is left floating, its internal pull-up keeps it high, leaving the boot block unprotected.
What status detection methods does the SST39VF1601-70-4I-B3KE-T support during write operations?
The SST39VF1601-70-4I-B3KE-T supports two real-time status detection methods: Data# Polling (DQ7 toggles until completion, then returns true data) and Toggle Bit (DQ6 toggles during internal program/erase). Both are valid after specific WE# edges-DQ7 after the fourth pulse for program, sixth for erase-and require no additional hardware.
Is the SST39VF1601-70-4I-B3KE-T pin-compatible with the SST39VF1602 or SST39VF3201 variants?
No, the SST39VF1601-70-4I-B3KE-T is not pin-compatible with SST39VF1602 or SST39VF3201. While all share the same 48-pin TSOP package and JEDEC x16 pinout, SST39VF1602 uses top-boot protection (requiring different WP# behavior), and SST39VF3201 is 32 Mbit (2M × 16) with A20 addressing-making direct substitution electrically and logically invalid without firmware and layout changes.
