Product details
Overview
SST39VF1602-70-4I-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 top 32 KWord hardware block protection. It supports sector-, block-, and chip-erase, erase-suspend/resume, and Security ID functionality for embedded firmware storage in industrial control and legacy communication systems.
For engineers reviewing the SST39VF1602-70-4I-B3KE-T datasheet, SST39VF1602-70-4I-B3KE-T pinout, SST39VF1602-70-4I-B3KE-T application, or SST39VF1602-70-4I-B3KE-T equivalent, key selection considerations include its TSOP-48 package, JEDEC-compliant x16 asynchronous interface, top-boot block protection scheme, 100,000-cycle endurance, and compatibility with standard flash command sets including CFI and Software Data Protection.
Technical Context
The SST39VF1602-70-4I-B3KE-T implements SST's SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. It uses standard microprocessor bus timing with CE#, OE#, and WE# control signals and latched address/data paths.
It supports three primary write protection mechanisms: hardware WP#-enabled top-block lock, software data protection via six-byte command sequences, and RST#-initiated hard reset to recover from failed operations. The device enters 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 (1,048,576 × 16-bit words), enabling compact firmware storage for 8/16-bit microcontrollers |
| Read Access Time | 70 ns - determines maximum sustained read throughput in legacy parallel bus systems |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V logic domains and tolerant of brown-out conditions |
| Endurance | 100,000 program/erase cycles - supports field-upgradable firmware with long service life |
| Data Retention | >100 years - ensures nonvolatile storage integrity across product lifecycles without refresh |
| Erase Granularity | Uniform 2 KWord sectors and 32 KWord blocks - enables fine-grained firmware partitioning and recovery |
| Protection Scheme | Top 32 KWord hardware block protection (0F8000H–0FFFFFH) - safeguards boot code against accidental overwrite |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS compliant, surface-mountable with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | A0–A18 used for full 1M×16 addressing; A19 selects top boot block (0F8000H–0FFFFFH) during protection |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus with tri-state outputs controlled by CE# and OE#; latched internally during writes |
| 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; high forces DQx into high-impedance state |
| WE# | Write Enable | Active-low write strobe - latches address/data on falling/rising edges per JEDEC-standard timing |
| WP# | Write Protect | Active-low hardware lock - disables program/erase on top 32 KWord block when grounded |
| RST# | Reset | Active-low hardware abort - terminates in-progress erase/program and returns to read mode |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; dual ground pins (pins 23 & 47) reduce noise coupling in high-speed reads |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows real-time read access to non-suspended sectors during background erase - critical for fail-safe firmware updates |
| Security ID | 256-bit space (128-bit factory + 128-bit user) - enables secure device authentication and anti-cloning in OEM systems |
| CFI Support | JEDEC-standard Common Flash Interface - enables automatic detection and configuration by bootloader or OS flash drivers |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - lowers system power in intermittently polled applications |
| Toggle Bit & Data# Polling | Dual status reporting (DQ6/DQ7) - eliminates need for external polling timers and simplifies host firmware implementation |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C | Same density and voltage range, but bottom 32 KWord hardware protection instead of top; 55 ns access time; newer revision with improved reliability specs | Requires PCB layout change to relocate protected region - suitable only where boot code resides in lowest memory segment | Select if new design requires enhanced endurance or bottom-boot architecture; not drop-in compatible due to protection mapping and timing |
| MX29LV160ETTI-70G | 16 Mbit x16 flash with 70 ns access, 2.7–3.6 V, but uses different command set (no CFI); lacks Security ID and erase-suspend | Compatible pinout in TSOP-48, but requires firmware driver rewrite for erase/write commands and status polling | Consider only when legacy system firmware already supports Macronix command protocol and Security ID is unnecessary |
Compared with SST39VF1602-70-4I-B3KE-T, SST39VF1601C offers tighter timing and updated process but shifts protection to bottom block, while MX29LV160ETTI-70G provides mechanical compatibility at the cost of feature parity and driver portability.

FAQ
What is the memory organization of the SST39VF1602-70-4I-B3KE-T?
The SST39VF1602-70-4I-B3KE-T is organized as 1,048,576 words × 16 bits (16 Mbit total). Its address space spans 000000H to 0FFFFFH, with the top 32 KWord block (0F8000H–0FFFFFH) designated as hardware-protected boot sector. This structure supports direct mapping to 16-bit microprocessor buses without address translation logic.
Does the SST39VF1602-70-4I-B3KE-T support CFI (Common Flash Interface)?
Yes, the SST39VF1602-70-4I-B3KE-T fully supports JEDEC-standard CFI. Entering CFI Query mode via the 5555H/AAH–2AAAH/55H–5555H/98H command sequence allows host systems to auto-detect device geometry, timing parameters, and command set - simplifying driver development and enabling interoperability across flash vendors.
How does hardware block protection work on the SST39VF1602-70-4I-B3KE-T?
Hardware block protection on the SST39VF1602-70-4I-B3KE-T is activated by grounding the WP# pin, which locks the top 32 KWord (0F8000H–0FFFFFH) from program and erase operations. When WP# is left floating or pulled high, the protection is disabled. This mechanism operates independently of software commands and remains active during power transitions.
What is the purpose of the RST# pin on the SST39VF162-70-4I-B3KE-T?
The RST# pin on the SST39VF1602-70-4I-B3KE-T provides hardware-level abort and recovery: holding RST# low for ≥ TRP (100 ns) terminates any in-progress erase or program operation and forces the device back into read mode. This ensures deterministic state recovery during power faults or watchdog timeouts in safety-critical systems.
Is the SST39VF1602-70-4I-B3KE-T still recommended for new designs?
No - Microchip explicitly marks the SST39VF1602-70-4I-B3KE-T as "Not Recommended for New Designs" in DS25028A. It is superseded by the SST39VF1601C for top-boot variants and SST39VF1601B for bottom-boot variants, which offer improved reliability, tighter timing, and updated manufacturing process. Existing designs may continue using SST39VF1602-70-4I-B3KE-T under lifecycle support.
