Product details
Overview
SST39VF3202B-70-4C-EKE from Microchip Technology is a 32 Mbit (2M × 16) Multi-Purpose Flash Plus (MPF+) memory IC with single-supply 2.7–3.6 V operation, 70 ns read access time, top 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface - deployed in embedded boot code storage for industrial controllers requiring reliable in-field firmware updates.
For engineers reviewing the SST39VF3202B-70-4C-EKE datasheet, SST39VF3202B-70-4C-EKE pinout, SST39VF3202B-70-4C-EKE application, or SST39VF3202B-70-4C-EKE equivalent, key selection considerations include top-boot block protection configuration, 48-pin TSOP package compatibility, 100,000-cycle endurance, and SuperFlash® technology's fixed erase/program timing independent of wear level.
Technical Context
The SST39VF3202B-70-4C-EKE implements SST's proprietary SuperFlash® split-gate cell architecture with thick-oxide tunneling injector, enabling fixed 18 ms sector/block-erase and 7 µs word-program times regardless of accumulated program/erase cycles. It supports JEDEC-standard x16 pinout and operates across commercial temperature range (0°C to +70°C).
Its command-set architecture requires six-byte sequences for sector/block/chip-erase, includes Erase-Suspend/Erase-Resume (B0H/30H), and uses DQ6/DQ7 status bits for write completion detection. Hardware block protection is activated via WP# grounding to lock the top 32 KWord (1F8000H–1FFFFFH), distinguishing it from the bottom-protected SST39VF3201B.
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 max; ensures deterministic timing for real-time boot code fetch in systems with ≤14 MHz bus clocks. |
| Supply Voltage Range | 2.7–3.6 V; compatible with 3.3 V logic domains and tolerant of brown-out conditions down to 2.7 V during active operation. |
| Endurance & Retention | 100,000 program/erase cycles typical; >100 years data retention - validated for long-lifecycle industrial deployments without refresh. |
| Erase/Program Timing | Sector/Block-Erase: 18 ms typ.; Chip-Erase: 35 ms typ.; Word-Program: 7 µs typ. - fixed durations eliminate software de-rating over device lifetime. |
| Protection Scheme | Top 32 KWord hardware block protection (1F8000H–1FFFFFH) enabled by WP# low; prevents accidental overwrite of boot loader during field firmware updates. |
| Operating Temperature | 0°C to +70°C (Commercial grade); qualified for use in non-extended-temperature industrial control panels and networking edge devices. |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | 21-bit address bus (AMS = A20); A11–A20 select sector during Sector-Erase; A15–A20 select block during Block-Erase. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; latched internally during writes; tri-stated when CE# or OE# is high. |
| CE# | Chip Enable | Active-low chip select; device enters standby (4 µA) when high; required low for all read/write operations. |
| OE# | Output Enable | Active-low output gate; controls data bus drive; must be low with CE# low to enable read data output. |
| WE# | Write Enable | Active-low write strobe; latches address/data on falling/rising edges per JEDEC x16 protocol; initiates internal program/erase. |
| WP# | Write Protect | Active-low top-block lock; grounds to protect 1F8000H–1FFFFFH; floating = internally pulled high = unprotected. |
| RST# | Hardware Reset | Active-low reset input; forces immediate return to Read mode; required TRP low pulse to abort ongoing erase/program. |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; decoupling mandatory near pins; VSS provides reference for all I/O and core logic. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell with thick-oxide tunneling injector delivers fixed 18 ms erase and 7 µs program times - eliminates software timing margin growth over 100k cycles. |
| Top Boot Block Protection | Hardware-enforced lock of top 32 KWord (1F8000H–1FFFFFH) via WP# pin - safeguards boot loader without firmware intervention. |
| Erase-Suspend Capability | Issuing B0H command pauses active sector/block erase, enabling safe read/program of other regions - critical for real-time system responsiveness. |
| Security ID Space | 128-bit factory-programmed ID + 128-word user-programmable space - supports device authentication and secure firmware binding. |
| Auto Low Power Mode | Enters 4 µA standby automatically after valid read; exits instantly on address/control transition - reduces average active current in burst-read applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF3201B-70-4C-EKE | Bottom 32 KWord hardware block protection (000000H–007FFFH); identical timing, voltage, and package. | Used where boot loader resides in lowest memory region; incompatible for top-boot systems without PCB redesign. | Select only if bottom-boot architecture matches system memory map and WP# logic is inverted in layout. |
| MX29LV320ETTI-70G | 32 Mbit x16, 70 ns, 2.7–3.6 V; supports CFI but lacks Erase-Suspend and Security ID; different command set and pinout. | Requires firmware adaptation for erase commands; no hardware suspend capability limits real-time update safety. | Choose when legacy codebase already supports Macronix command set and Erase-Suspend is not required. |
Compared with SST39VF3202B-70-4C-EKE, the SST39VF3201B offers mirrored block protection but identical performance, while MX29LV320ETTI-70G trades advanced features like Erase-Suspend and Security ID for broader second-source availability - making SST39VF3202B-70-4C-EKE optimal for new designs prioritizing update safety and device identity.

FAQ
What is the function of the WP# pin on the SST39VF3202B-70-4C-EKE?
The WP# (Write Protect) pin on the SST39VF3202B-70-4C-EKE enables hardware-level protection of the top 32 KWord boot block (1F8000H–1FFFFFH). When grounded, it prevents all Program and Erase operations to that region. If left floating, an internal pull-up holds WP# high, disabling protection. This behavior is specific to the SST39VF3202B-70-4C-EKE and differs from the bottom-protect variant SST39VF3201B.
Does the SST39VF3202B-70-4C-EKE support Erase-Suspend, and how is it used?
Yes, the SST39VF3202B-70-4C-EKE supports Erase-Suspend via the B0H command. Issuing this command pauses an active Sector- or Block-Erase operation, allowing the host to read from or program other unprotected sectors. The device enters read mode within 10 µs. To resume, the Erase Resume command (30H) must be issued. This capability is confirmed in the DS25111A datasheet Section 5 and is a distinguishing feature of the SST39VF3202B-70-4C-EKE.
What package type is used for the SST39VF3202B-70-4C-EKE, and is it RoHS-compliant?
The SST39VF3202B-70-4C-EKE is supplied in a 48-lead TSOP (12 mm × 20 mm) package, as specified in the DS25111A datasheet Figure 2 and Section "Packages Available". All non-Pb (lead-free) versions, including this part, are RoHS compliant per the datasheet statement on page 1. The -EKE suffix denotes the TSOP packaging variant.
How does the SST39VF3202B-70-4C-EKE differ from the SST39VF3201B-70-4C-EKE?
The SST39VF3202B-70-4C-EKE implements top 32 KWord hardware block protection (1F8000H–1FFFFFH), whereas the SST39VF3201B-70-4C-EKE protects the bottom 32 KWord (000000H–007FFFH). Both share identical timing (70 ns access), voltage (2.7–3.6 V), endurance (100k cycles), and package. The difference is strictly in protection address mapping and WP# functional behavior - confirmed in Table 3 and Section 8 of DS25111A.
What is the purpose of the RST# pin on the SST39VF3202B-70-4C-EKE?
The RST# (Reset) pin on the SST39VF3202B-70-4C-EKE provides hardware-initiated recovery to Read mode. Holding RST# low for ≥TRP (typically 100 ns) terminates any in-progress Program or Erase operation and forces the device into Read mode. After release, a minimum TRHR delay (≥100 ns) is required before valid reads. This function is documented in Section 9 of DS25111A and applies identically to the SST39VF3202B-70-4C-EKE.
