Product details
Overview
SST39VF3202-70-4C-EKE from Microchip Technology is a 32 Mbit (2M × 16) Multi-Purpose Flash Plus (MPF+) memory IC designed for embedded firmware, BIOS, and configuration storage in industrial and communications systems. It operates from 2.7–3.6 V, delivers 70 ns read access time, supports hardware top-block protection (32 KWord), and features erase-suspend/resume, security ID, and JEDEC-standard x16 asynchronous interface.
For engineers reviewing the SST39VF3202-70-4C-EKE datasheet, SST39VF3202-70-4C-EKE pinout, SST39VF3202-70-4C-EKE application, or SST39VF3202-70-4C-EKE equivalent, this page provides verified technical context, JEDEC-compliant pin mapping, real-world use cases in boot code storage and field-upgradable firmware, and two validated alternative flash devices with documented functional and packaging differences.
Technical Context
The SST39VF3202-70-4C-EKE implements SST's SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed 7 µs word-program and 18 ms sector/block-erase times independent of cycle count. It uses standard microprocessor bus timing with CE#, OE#, and WE# control signals and supports both software data protection (6-byte erase/3-byte program sequences) and hardware write protection via WP#.
It conforms to JEDEC-standard x16 flash pinouts and command sets, includes CFI query capability for automatic system identification, and integrates dual 128-bit Security ID (factory + user programmable). The device supports Auto Low Power mode (3 µA standby), toggle-bit (DQ6/DQ2) and data-polling (DQ7) status detection, and hardware reset (RST#) for reliable recovery from interrupted operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 Mbit (2M × 16 organization), providing 4 MB of nonvolatile storage for full BIOS or application firmware images. |
| Read Access Time | 70 ns - enables direct execution (XIP) from flash in legacy x86 and ARM-based boot loaders without wait states. |
| Supply Voltage | 2.7–3.6 V - compatible with single-supply 3.3 V systems; no external VPP required due to internal charge pump. |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years in telecom or industrial gateways. |
| Data Retention | >100 years - ensures long-term reliability in unattended infrastructure equipment without refresh. |
| Block Protection | Top 32 KWord (1F8000H–1FFFFFH) protected when WP# = low - safeguards boot code against accidental overwrite. |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) - allows fine-grained updates without erasing entire firmware image. |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, surface-mount. Pinout validated per DS25028A Figure 2 (48-lead TSOP standard pinout).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | A0–A19 used for 2M×16 addressing; A20 selects top address bit (1F8000H–1FFFFFH); unused pins are NC. |
| DQ0–DQ15 | Data I/O (x16 bus) | Bi-directional CMOS-compatible data bus; latched internally during writes; tri-stated when CE# or OE# high. |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write; controls address/data latch timing with WE#. |
| OE# | Output Enable | Active-low output gate; enables data output only when CE# and OE# both low; prevents bus contention. |
| WE# | Write Enable | Controls write strobe timing; falling edge latches address, rising edge latches data for program/erase commands. |
| WP# | Hardware Write Protect | Low = locks top 32 KWord boot block; floating = internally pulled high, disabling protection. |
| RST# | Hardware Reset | Active-low; forces immediate return to read mode; required TRP pulse width ≥ 100 ns to abort ongoing erase/program. |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; decoupling capacitor required near VDD pin to maintain stable operation during fast transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows reading or programming other sectors during active erase - critical for real-time systems requiring background firmware update verification. |
| Security ID | 256-bit space (128-bit factory + 128-bit user) - enables secure device authentication and anti-cloning in OEM embedded platforms. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts power in always-on network controllers without sacrificing responsiveness. |
| Fixed Erase/Program Timing | No degradation over 100,000 cycles - eliminates need for system-level timeout de-rating or wear-leveling firmware overhead. |
| JEDEC x16 Command Set | Fully compatible with industry-standard flash controllers and boot ROM interfaces - ensures drop-in replacement in legacy designs. |
Applications
| Industrial PLC Firmware Storage | Telecom Base Station Boot Code |

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 32 Mbit density and TSOP package, but bottom-block protection (000000H–007FFFH) instead of top-block; 55 ns access time. | Requires PCB layout change if top-boot protection is mandatory; better suited for legacy designs using bottom-boot architecture. | Select only if existing design uses bottom-boot layout or requires faster 55 ns access; not pin-compatible for top-boot use cases. |
| MX29LV320ETTI-70G | 32 Mbit x16 flash from Macronix; 70 ns access, same TSOP-48 package; supports CFI but lacks Security ID and erase-suspend. | Lacks hardware suspend/resume and 256-bit ID - unsuitable for secure or real-time update applications requiring concurrent access. | Use where cost is primary constraint and security/real-time features are unnecessary; verify JEDEC command set compatibility in host firmware. |
Compared with SST39VF3202-70-4C-EKE, SST39VF3201B offers faster access but incompatible block protection location, while MX29LV320ETTI-70G omits critical security and concurrency features - making SST39VF3202-70-4C-EKE uniquely suitable for secure, field-upgradable embedded systems requiring top-boot integrity.

FAQ
What is the memory organization and total capacity of the SST39VF3202-70-4C-EKE?
The SST39VF3202-70-4C-EKE is organized as 2M × 16 bits, delivering 32 Mbit (4 MB) of nonvolatile flash memory. This structure supports x16 parallel bus interfacing and is optimized for storing full firmware images, boot code, and configuration data in embedded systems requiring direct execution capability.
Does the SST39VF3202-70-4C-EKE support hardware write protection, and how is it configured?
Yes, the SST39VF3202-70-4C-EKE supports hardware top-block protection for the upper 32 KWord (1F8000H–1FFFFFH) via the WP# pin. When WP# is driven low, program and erase operations on that region are disabled. If left floating, an internal pull-up holds WP# high, disabling protection - ensuring safe default behavior at power-up.
What are the supported erase granularities for the SST39VF3202-70-4C-EKE?
The SST39VF3202-70-4C-EKE supports three erase modes: sector-erase (2 KWord = 4 KB), block-erase (32 KWord = 64 KB), and chip-erase (full 4 MB). All erase operations complete in typical times of 18 ms (sector/block) or 40 ms (chip), with fixed timing unaffected by endurance cycling.
How does the SST39VF3202-70-4C-EKE indicate completion of program or erase operations?
The SST39VF3202-70-4C-EKE provides two software-detectable status mechanisms: Data# Polling (DQ7 toggles until completion, then outputs true data) and Toggle Bits (DQ6 toggles during operation, stops when complete). Both are valid after defined WE#/CE# edges and require no additional hardware signaling.
Is the SST39VF3202-70-4C-EKE pin-compatible with other devices in the SST39VF320x family?
The SST39VF3202-70-4C-EKE shares identical pinout and command set with SST39VF3201 in 48-lead TSOP, but differs in block protection location (top vs. bottom) and device ID. It is not pin-compatible with SST39VF160x variants due to differing address depth (A20 required) and memory size decoding requirements.
