Product details
Overview
SST39VF3202C-70-4I-B3KE-T from Microchip Technology is a 32-Mbit (2M × 16) CMOS Multi-Purpose Flash Plus (MPF+) memory IC with top-boot block protection, 70 ns read access time, 2.7–3.6 V single-supply operation, and JEDEC-standard x16 pinout - used for firmware storage, boot code execution, and configuration data retention in embedded controllers and industrial systems.
For engineers reviewing the SST39VF3202C-70-4I-B3KE-T datasheet, SST39VF3202C-70-4I-B3KE-T pinout, SST39VF3202C-70-4I-B3KE-T application, or SST39VF3202C-70-4I-B3KE-T equivalent, key selection considerations include top-block hardware write protection (WP#), RY/BY# status signaling, erase-suspend capability, and TSOP/TBGA package compatibility with legacy x16 parallel bus interfaces.
Technical Context
This device implements SuperFlash® technology with split-gate cells and thick-oxide tunneling injectors to deliver fixed 18 ms sector/block erase and 7 µs word-program times independent of cycle count - eliminating software derating required by conventional flash. It supports three software detection methods (DQ7 Data# Polling, DQ6/DQ2 Toggle Bits, and open-drain RY/BY#) for end-of-write verification.
The SST39VF3202C-70-4I-B3KE-T features dual-mode hardware protection: WP# enables top two 4-KWord boot blocks (1FE000H–1FFFFFH) while RST# provides hardware reset to Read mode. Its CFI-compliant interface allows runtime identification and parameter querying without external configuration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2M × 16 (32 Mbit); supports byte-wide or word-wide addressing via A0–A20 and DQ0–DQ15 |
| Read Access Time | 70 ns max; enables direct execution from flash (XIP) in microcontrollers with ≤14 MHz bus timing |
| Supply Voltage | 2.7 V–3.6 V; compatible with 3.3 V logic systems and eliminates need for separate VPP programming voltage |
| Endurance & Retention | 100,000 program/erase cycles typical; >100 years data retention at 25°C - suitable for infrequently updated firmware |
| Erase/Program Times | Sector/Block-Erase: 18 ms typ; Chip-Erase: 35 ms typ; Word-Program: 7 µs typ - deterministic timing simplifies real-time system scheduling |
| Power Consumption | Active current: 6 mA typ @ 5 MHz; Standby/Auto-Low-Power: 4 µA typ - reduces quiescent power in battery-backed systems |
| Protection Features | Hardware top-block protection (WP#), Software Data Protection (SDP), Security ID (128-bit factory + 128-word user), and RST# reset |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm) - RoHS-compliant, surface-mount, JEDEC-standard footprint for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | A0–A19 select 2M words; A20 (AMS) determines top/bottom boot block address decoding during erase commands |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; latched internally during writes; tri-state when CE# or OE# high |
| CE#, OE#, WE# | Control Enables | Standard x16 parallel interface controls: chip select, output enable, write enable - fully compatible with 8086/ARM bus protocols |
| WP# | Write-Protect Input | Active-low; protects top two 4-KWord boot blocks (1FE000H–1FFFFFH) from accidental erase/program |
| RST# | Hardware Reset | Active-low; forces immediate return to Read mode, terminating any in-progress erase/program operation |
| RY/BY# | Ready/Busy Output | Open-drain status signal; pulled low during internal erase/program; requires external 10–100 kΩ pull-up |
| VDD, VSS | Power/Ground | Single 2.7–3.6 V supply; no VPP required - simplifies power rail design |
| NC | No Connection | Unbonded pins (e.g., Pin 3, Pin 26 in TSOP); must be left floating or tied to ground per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows temporary halt of sector/block erase to read or program other regions - critical for real-time firmware updates without full system stall |
| Auto Low-Power Mode | Reduces active read current from 6 mA to 4 µA after valid read access - cuts standby power by >99% in idle periods |
| Top Boot Block Protection | Hardware-enforced write lock on top 8 KWords (1FE000H–1FFFFFH) - ensures bootloader integrity against corruption |
| Security ID Space | Factory-programmed 128-bit ID + 128-word user space - enables secure device authentication and firmware binding |
| CFI Query Support | JEDEC-standard Common Flash Interface allows runtime detection of density, timings, and command sets - simplifies driver portability across flash vendors |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF3201C-70-4I-B3KE-T | Bottom-boot architecture (protects lowest 8 KWords); identical timing, voltage, and command set | Used where bootloader resides in lower memory map (000000H–001FFFH) instead of top region | Select when system firmware requires bottom-block protection and shares same PCB layout |
| MX29LV320ETTI-70G | 32 Mbit x16, 70 ns, 2.7–3.6 V; supports CFI but lacks Security ID and erase-suspend | Lower cost alternative for non-security-critical applications; no hardware boot-block protection | Choose for cost-sensitive designs where security ID and suspend/resume are not required |
Compared with SST39VF3202C-70-4I-B3KE-T, the SST39VF3201C variant offers mirrored boot-block protection for bottom-addressed firmware, while the MX29LV320ETTI-70G provides baseline flash functionality without security or advanced suspend features - making it suitable only for simpler, non-certified systems.

FAQ
What is the exact memory organization and density of the SST39VF3202C-70-4I-B3KE-T?
The SST39VF3202C-70-4I-B3KE-T is organized as 2M × 16, delivering 32 Mbit (4 MB) of nonvolatile storage. Each word is 16 bits wide, addressed via A0–A20 (21 address lines), with DQ0–DQ15 providing full parallel data transfer. This structure supports both word-level and byte-level access in systems with appropriate bus-width translation.
Does the SST39VF3202C-70-4I-B3KE-T support hardware write protection, and how is it implemented?
Yes, the SST39VF3202C-70-4I-B3KE-T implements top-boot hardware block protection via the WP# pin. When WP# is driven low, the top two 4-KWord blocks (1FE000H–1FFFFFH) are locked against erase and program operations. This protection is active regardless of software state and remains effective during power transitions, ensuring bootloader integrity.
How does the SST39VF3202C-70-4I-B3KE-T indicate completion of an erase or program operation?
The SST39VF3202C-70-4I-B3KE-T provides three concurrent status mechanisms: DQ7 Data# Polling (complement-to-data toggle), DQ6/DQ2 Toggle Bits (alternating 1/0 during operation), and the open-drain RY/BY# pin (low = busy, high = ready). All are valid after the rising edge of the sixth WE# pulse for erase commands and fourth WE# pulse for program commands.
What package type is used for the SST39VF3202C-70-4I-B3KE-T, and is it RoHS-compliant?
The SST39VF3202C-70-4I-B3KE-T is supplied in a 48-lead TSOP (12 mm × 20 mm) package, with JEDEC-standard pinout and RoHS compliance confirmed per Microchip documentation. This package supports standard reflow soldering profiles and is compatible with automated SMT assembly lines.
Can the SST39VF3202C-70-4I-B3KE-T be used in systems requiring secure device identification?
Yes, the SST39VF3202C-70-4I-B3KE-T includes a dedicated Security ID space: 128 bits factory-programmed by Microchip and 128 words (256 bytes) user-programmable. The user segment can be permanently locked after programming, enabling cryptographic binding of firmware to hardware - a key requirement for anti-counterfeiting and secure boot implementations.
