Product details
Overview
SST39VF3202B-70-4I-B3KE-T from Microchip Technology is a 32 Mbit (2M × 16) Multi-Purpose Flash Plus 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 (32 KWord), and features sector/block/chip erase with erase-suspend/resume capability.
For engineers reviewing the SST39VF3202B-70-4I-B3KE-T datasheet, SST39VF3202B-70-4I-B3KE-T pinout, SST39VF3202B-70-4I-B3KE-T application, or SST39VF3202B-70-4I-B3KE-T equivalent, key selection considerations include x16 asynchronous interface timing, JEDEC-compliant TSOP-48 pinout, top-boot block protection address range (1F8000H–1FFFFFH), and SuperFlash technology's fixed 7 µs word-program time independent of endurance cycles.
Technical Context
The SST39VF3202B-70-4I-B3KE-T implements SST's proprietary SuperFlash split-gate cell architecture with thick-oxide tunneling injector, enabling guaranteed 100,000 program/erase cycles and >100 years data retention. Its command-set-driven operation uses standard microprocessor write sequences with six-byte erase commands and three-byte program initiation, fully compliant with JEDEC x16 flash pin assignments.
It integrates hardware block protection via WP# tied low to lock the top 32 KWord boot block (1F8000H–1FFFFFH), supports CFI query mode for automatic device identification, and provides dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits) for precise end-of-write monitoring during program or erase operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2M × 16 (32 Mbit total); enables 16-bit parallel data bus interfacing with microcontrollers and SoCs without external data-width conversion. |
| Read Access Time | 70 ns; ensures compatibility with high-speed 14 MHz+ bus clocks in industrial control and networking applications. |
| Supply Voltage | 2.7–3.6 V; allows direct integration into 3.3 V systems without level-shifting or auxiliary regulators. |
| Endurance | 100,000 cycles (typical); supports frequent firmware updates or field-configurable parameter storage over product lifetime. |
| Data Retention | >100 years; guarantees long-term integrity of boot code and calibration data in unpowered storage. |
| Word-Program Time | 7 µs (typical); reduces firmware update latency and improves system responsiveness during in-field reprogramming. |
| Erase Capability | Sector (2 KWord), Block (32 KWord), Chip; enables granular updates-e.g., patching one application module without erasing boot loader. |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | A0–A19 select 2M words; A20 (AMS) used for sector/block address decoding during erase commands. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional 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 read/write operations; controls device activation in multi-chip memory maps. |
| OE# | Output Enable | Active-low output gate; enables data output only when CE# and OE# are both low-critical for bus contention avoidance. |
| WE# | Write Enable | Controls timing of write latching; falling edge latches address, rising edge latches data per JEDEC x16 protocol. |
| WP# | Write Protect | Hardware top-block lock: grounded to protect 1F8000H–1FFFFFH; floating = internal pull-up = unprotected. |
| 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; VSS pins at positions 23, 47 provide dedicated ground paths for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows real-time read access to non-suspended sectors during active erase-enabling background firmware validation while updating other regions. |
| Auto Low Power Mode | Reduces active read current from 6 mA to 4 µA after valid access, cutting standby power in always-on edge devices. |
| Security ID Space | 128-bit factory-programmed + 128-word user-programmable ID; supports secure boot authentication and device binding. |
| SuperFlash Reliability | Fixed 7 µs program and 18 ms erase times across full 100K-cycle life-eliminates software de-rating or timeout scaling. |
| JEDEC x16 Compliance | Pin-compatible with industry-standard x16 flash memories, simplifying drop-in replacement in existing PCB layouts. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar x16 parallel flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV320ETTI-70G | 3.0–3.6 V supply only; no 2.7 V support; 70 ns access but no erase-suspend feature. | Lacks real-time suspend capability-unsuitable for systems requiring concurrent read access during firmware update. | Select when 2.7 V operation and erase-suspend are not required; verify board-level voltage regulator compatibility. |
| S29GL032N90TFIR20 | 48-pin TSOP but uses CFI-compliant command set; 90 ns access; 100K cycles but no hardware top-block protection pin (WP#). | Relies on software-only protection; requires additional MCU firmware logic to emulate top-block lock. | Prefer when CFI auto-detection is mandatory; avoid where hardware WP#-based boot security is mandated by safety standards. |
Compared with MX29LV320ETTI-70G and S29GL032N90TFIR20, the SST39VF3202B-70-4I-B3KE-T uniquely combines 2.7 V minimum operation, hardware top-block protection via dedicated WP#, and erase-suspend functionality-making it optimal for safety-critical, low-voltage, and real-time update applications.

FAQ
What is the exact memory organization and density of the SST39VF3202B-70-4I-B3KE-T?
The SST39VF3202B-70-4I-B3KE-T is organized as 2M × 16, delivering 32 Mbit (4 MByte) of nonvolatile storage. This x16 configuration interfaces directly with 16-bit data buses in microcontrollers and SoCs, eliminating the need for external data multiplexing or glue logic in legacy embedded designs.
Does the SST39VF3202B-70-4I-B3KE-T support hardware write protection, and how is it configured?
Yes-the SST39VF3202B-70-4I-B3KE-T implements hardware top-block protection via the WP# pin. When WP# is driven low, the top 32 KWord block (address range 1F8000H–1FFFFFH) is locked against program and erase operations. If left floating, an internal pull-up holds WP# high, leaving the block unprotected.
What erase capabilities does the SST39VF3202B-70-4I-B3KE-T provide, and what are their typical durations?
The SST39VF3202B-70-4I-B3KE-T supports sector-erase (2 KWord, 18 ms typical), block-erase (32 KWord, 18 ms typical), and chip-erase (35 ms typical). All erase operations use command sequences initiated via WE#/CE# and support status monitoring via DQ6 toggle or DQ7 polling.
How does the SST39VF3202B-70-4I-B3KE-T handle power supply variations, and what is its operating voltage range?
The SST39VF3202B-70-4I-B3KE-T operates across a single 2.7–3.6 V supply-fully compatible with standard 3.3 V systems. It includes VDD power-up/down detection that inhibits writes below 1.5 V, and noise/glitch protection rejecting WE#/CE# pulses under 5 ns, ensuring robust operation in electrically noisy environments.
Is the SST39VF3202B-70-4I-B3KE-T pin-compatible with other x16 flash memories, and which package does it use?
Yes-the SST39VF3202B-70-4I-B3KE-T uses a JEDEC-standard 48-lead TSOP package (12 mm × 20 mm) with pin assignments fully compliant with x16 parallel flash specifications. This enables direct substitution in existing designs using compatible footprints, provided voltage and timing margins are verified.
