Product details
Overview
SST39VF3202B-70-4I-B3KE from Microchip Technology is a 32 Mbit (2M × 16) Multi-Purpose Flash Plus (MPF+) memory IC designed for nonvolatile program, configuration, and data storage in embedded systems. It operates at 2.7–3.6 V, 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 datasheet, SST39VF3202B-70-4I-B3KE pinout, SST39VF3202B-70-4I-B3KE application, or SST39VF3202B-70-4I-B3KE equivalent, this page provides verified functional identity, JEDEC-compliant x16 interface timing, top-boot block protection mapping, SuperFlash endurance/reliability metrics, and real-world use context for industrial firmware storage and boot code retention.
Technical Context
The SST39VF3202B-70-4I-B3KE 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 architecture supports uniform 2 KWord sectors (1024 total) and 32 KWord blocks (64 total), with JEDEC-standard x16 asynchronous interface timing.
It integrates hardware write protection via WP# for top 32 KWord boot block (address range 1F8000H–1FFFFFH), RST# for hardware reset to read mode, and dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits) for end-of-write verification during program/erase operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2,097,152 × 16-bit words); enables full firmware image storage in single-package footprint |
| Read Access Time | 70 ns max; ensures compatibility with 14 MHz bus timing without wait states in legacy microcontroller interfaces |
| Supply Voltage | 2.7–3.6 V; supports direct connection to 3.3 V logic rails without level-shifting or external regulators |
| Endurance | 100,000 program/erase cycles (typical); guarantees field-reliable firmware updates over 10+ years of industrial operation |
| Data Retention | >100 years; eliminates need for periodic refresh or backup power in unattended remote deployments |
| Erase Granularity | Sector (2 KWord), Block (32 KWord), Chip; allows selective firmware patching without full reflash downtime |
| Power Consumption | 6 mA active (5 MHz), 4 µA standby/auto-low-power; reduces system-level quiescent current in battery-backed applications |
Pinout & Package
Package: 48-ball TFBGA (6 mm × 8 mm, 0.8 mm pitch) and 48-lead TSOP (12 mm × 20 mm). The SST39VF3202B-70-4I-B3KE variant uses the 48-ball TFBGA package per B3KE suffix.
| Pin/Terminal | Circuit Role | Design Meaning |

| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus with latched inputs and tri-state outputs controlled by CE#/OE#; supports JEDEC x16 standard |
| WE#, CE#, OE# | Control Inputs | Asynchronous command gating: CE# enables chip, OE# gates output, WE# controls write initiation per JEDEC timing |
| WP# | Hardware Protect | Active-low input that locks top 32 KWord boot block (1F8000H–1FFFFFH); internally pulled up if floating |
| RST# | Reset Input | Hardware abort of in-progress erase/program; forces return to read mode within TRP (min 100 ns) |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; no VPP required due to internal charge pump for erase/program |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF3201B-70-4I-B3KE | Bottom-block protection (000000H–007FFFH); identical density, timing, and package | Used where boot code resides in lowest memory region; incompatible pin-for-pin replacement due to opposite protection scheme | Select only when bottom-boot architecture matches system memory map and bootloader location |
| MX29LV320ETTI-70G | 32 Mbit x16, 70 ns, 2.7–3.6 V, but uses different command set and lacks erase-suspend/resume | Requires modified driver stack; no background read capability during erase; lower reliability (10K cycles) | Choose only for cost-sensitive designs where erase-suspend is unnecessary and legacy driver reuse is prioritized |
Compared with SST39VF3201B-70-4I-B3KE, the SST39VF3202B-70-4I-B3KE provides top-boot protection essential for systems with upper-memory-resident bootloaders, while MX29LV320ETTI-70G offers vendor interchangeability at the expense of SuperFlash reliability and advanced suspend functionality.

FAQ
What is the exact memory organization of the SST39VF3202B-70-4I-B3KE?
The SST39VF3202B-70-4I-B3KE is organized as 2,097,152 words × 16 bits (32 Mbit total), with uniform 2 KWord sectors (1024 sectors) and 32 KWord blocks (64 blocks). Its top 32 KWord boot block spans address range 1F8000H–1FFFFFH, protected by the WP# pin when asserted low.
Does the SST39VF3202B-70-4I-B3KE require an external VPP voltage?
No, the SST39VF3202B-70-4I-B3KE does not require an external VPP voltage. It generates all necessary high-voltage programming/erasing signals internally using its on-chip charge pump, operating solely from the 2.7–3.6 V VDD supply.
How does hardware block protection work on the SST39VF3202B-70-4I-B3KE?
Hardware block protection on the SST39VF3202B-70-4I-B3KE is implemented via the WP# pin: when WP# is driven low, program and erase operations are disabled for the top 32 KWord boot block (1F8000H–1FFFFFH). If WP# is left floating, an internal pull-up holds it high, disabling protection.
What is the purpose of the RST# pin on the SST39VF3202B-70-4I-B3KE?
The RST# pin on the SST39VF3202B-70-4I-B3KE provides hardware-level reset: holding RST# low for ≥100 ns (TRP) terminates any in-progress erase or program operation and returns the device to read mode. After release, a minimum TRHR delay is required before valid reads resume.
Can the SST39VF3202B-70-4I-B3KE be used in place of the SST39VF3201B-70-4I-B3KE?
No - the SST39VF3202B-70-4I-B3KE and SST39VF3201B-70-4I-B3KE are not interchangeable. They differ in hardware block protection location: SST39VF3202B protects the top 32 KWord block, while SST39VF3201B protects the bottom block. Swapping them risks boot failure or unprotected firmware regions.
