Product details
Overview
SST39VF3202-70-4I-EKE from Microchip Technology is a 32 Mbit (2M × 16) CMOS Multi-Purpose Flash Plus memory IC with x16 asynchronous interface, 70 ns read access time, single 2.7–3.6 V supply operation, and top 32 KWord hardware block protection. It implements SuperFlash technology for high reliability in embedded firmware storage applications requiring in-system reprogrammability.
For engineers reviewing the SST39VF3202-70-4I-EKE datasheet, SST39VF3202-70-4I-EKE pinout, SST39VF3202-70-4I-EKE application, or SST39VF3202-70-4I-EKE equivalent, this page delivers verified specifications, JEDEC-compliant pin mapping, boot-block protection behavior, erase-suspend capability, and real-world design implications for legacy industrial controller and networking equipment upgrades.
Technical Context
The SST39VF3202-70-4I-EKE uses split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed 7 µs word-program and 18 ms sector/block-erase times independent of cycle count. Its command set conforms to JEDEC-standard x16 flash pinouts and supports Software Data Protection via six-byte sequences for erase and three-byte sequences for program.
It features dual status detection (DQ7 Data# Polling and DQ6 Toggle Bit), hardware WP#-controlled top-boot-block protection (1F8000H–1FFFFFH), RST#-driven hardware reset, and CFI Query mode for runtime device identification. 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 | 32 Mbit (2M × 16 organization), supporting 4 MB addressable space |
| Read Access Time | 70 ns - determines minimum bus cycle timing for 14.3 MHz sustained read throughput |
| Supply Voltage | 2.7–3.6 V - enables direct interfacing with 3.3 V logic without level-shifting |
| Endurance | 100,000 program/erase cycles - validated for field-upgradable firmware with infrequent updates |
| Data Retention | >100 years - ensures long-term integrity of stored boot code and configuration data |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) - enables selective firmware patching |
| Protection Scheme | Hardware top-block protection (32 KWord) via WP# pin - prevents accidental overwrite of boot loader region |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS compliant, JEDEC-standard x16 flash footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | A0–A19 used for 2M×16 addressing; A20 selects upper half of 4 MB space (SST39VF3202 only) |
| DQ0–DQ15 | Data Input/Output | x16 bidirectional data bus; latched internally during write; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write operations |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; high = high-Z |
| WE# | Write Enable | Active-low control for write cycles; latches address/data on falling/rising edges per JEDEC timing |
| WP# | Write Protect | Active-low hardware lock for top 32 KWord boot block (1F8000H–1FFFFFH) |
| RST# | Reset | Active-low hardware abort of ongoing erase/program; forces return to read mode within TRP |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; decoupling required per JEDEC layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Erase-Resume | Allows temporary halt of sector/block erase to read or program other regions - critical for real-time systems needing background firmware update |
| Security ID | 256-bit factory + user programmable ID space (128 + 128 bits), locked post-programming - enables secure device authentication and anti-cloning |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts standby power in battery-backed or energy-sensitive designs |
| SuperFlash Reliability | Fixed 7 µs program and 18 ms erase times across full endurance life - eliminates software de-rating or timeout expansion over time |
| JEDEC CFI Support | Standard Common Flash Interface query mode accessible at 5555H - enables OS/driver auto-detection without hard-coded part assumptions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF3201B | Same density and pinout; improved reliability spec (100K cycles guaranteed min); replaces SST39VF3202 in new designs per Microchip notice | Bottom-block protection instead of top-block; address range 000000H–007FFFH protected | Select when boot code resides in lower memory and legacy board layout allows bottom-protection mapping |
| MX29LV320ETTI-70G | 32 Mbit x16, 70 ns, 3.0–3.6 V; supports CFI but lacks erase-suspend and Security ID; different command set timing | No hardware boot-block protection; relies on software locking only | Use where cost sensitivity outweighs advanced features and existing firmware already handles software-based protection |
Compared with SST39VF3202-70-4I-EKE, SST39VF3201B offers identical footprint and voltage but shifts protection to the bottom block - requiring firmware address remapping - while MX29LV320ETTI-70G sacrifices erase-suspend and hardware security for broader distributor availability and lower unit cost in non-critical applications.

FAQ
What is the memory organization and total capacity of the SST39VF3202-70-4I-EKE?
The SST39VF3202-70-4I-EKE is organized as 2M × 16, delivering 32 Mbit (4 MB) of nonvolatile storage. Its address space spans 000000H to 1FFFFFH, with A0–A19 used for standard addressing and A20 enabling full 4 MB coverage. This x16 configuration matches common 16-bit microprocessor buses without data multiplexing, and the 70 ns access time supports up to 14.3 MHz read bandwidth in synchronous systems.
Does the SST39VF3202-70-4I-EKE support hardware write protection, and how is it configured?
Yes, the SST39VF3202-70-4I-EKE implements top 32 KWord hardware block protection activated by grounding the WP# pin. This protects the address range 1F8000H–1FFFFFH - the uppermost 64 KB - from accidental program or erase operations. When WP# is left floating, an internal pull-up holds it high, disabling protection. This feature is distinct from SST39VF3201, which protects the bottom 32 KWord block instead.
How does the SST39VF3202-70-4I-EKE indicate completion of a program or erase operation?
The SST39VF3202-70-4I-EKE provides two simultaneous status mechanisms: Data# Polling on DQ7 (complement toggles until completion, then returns true data) and Toggle Bit on DQ6 (toggles between 0/1 during operation, stops when complete). Both are valid after the rising edge of the fourth WE# pulse for word-program and sixth WE# pulse for erase commands. These methods eliminate need for fixed delays and enable optimal system-level timing.
Is the SST39VF3202-70-4I-EKE compatible with standard JEDEC flash command sets and pinouts?
Yes, the SST39VF3202-70-4I-EKE fully conforms to JEDEC Standard JESD21-C for x16 flash memories, including pin assignments, command protocols (e.g., 6-byte erase, 3-byte program unlock), and electrical signaling. It supports CFI Query mode (via 5555H/98H command) for runtime identification and is pin-compatible with other JEDEC-compliant 48-pin x16 flash devices using the same TSOP package.
What is the significance of the "Not Recommended for New Designs" status for the SST39VF3202-70-4I-EKE?
Microchip explicitly marks the SST39VF3202-70-4I-EKE as "Not Recommended for New Designs" in DS25028A, advising migration to SST39VF3201B for new projects. This reflects obsolescence planning - not immediate discontinuation - and indicates prioritized support, enhanced specs (e.g., guaranteed 100K cycles), and long-term supply assurance for the replacement. Existing designs may continue using SST39VF3202-70-4I-EKE under current lifecycle commitments.
