Product details
Overview
SST39VF3202C-70-4I-EKE from Microchip Technology is a 32-Mbit (2M × 16) CMOS Multi-Purpose Flash Plus (MPF+) memory IC with SuperFlash® technology, operating at 2.7V–3.6V, featuring 70 ns read access time, hardware top-block write protection, and JEDEC-standard x16 pinout. It serves as nonvolatile program/data storage in embedded boot code, firmware update, and configuration memory applications.
For engineers reviewing the SST39VF3202C-70-4I-EKE datasheet, SST39VF3202C-70-4I-EKE pinout, SST39VF3202C-70-4I-EKE application, or SST39VF3202C-70-4I-EKE equivalent, key selection criteria include top-boot block protection address range (1FE000H–1FFFFFH), 100,000-cycle endurance, 4 µA standby current, and TSOP/TBGA package compatibility for space-constrained industrial controllers.
Technical Context
The SST39VF3202C-70-4I-EKE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count-unlike conventional flash technologies where timing degrades over endurance life. Its command-set-driven operation relies on six-byte sequences for sector/block/chip erase and three-byte sequences for word programming, all validated via DQ6 toggle-bit or DQ7 data-polling status detection.
Hardware block protection is implemented via the WP# pin to lock the top two 4-KWord boot blocks (1FE000H–1FFFFFH), while RY/BY# provides open-drain ready/busy signaling requiring external 10 kΩ–100 kΩ pull-up. The device supports CFI query mode (0x98 command) and Security ID with factory-programmed 128-bit ID and user-programmable 128-word segment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 2M × 16 (32 Mbit total); supports x16 data bus interface without byte-lane splitting. |
| Read Access Time | 70 ns; enables direct execution from flash (XIP) in microcontroller boot loaders with minimal wait states. |
| Supply Voltage | 2.7V–3.6V; compatible with 3.3V logic systems and tolerant of brown-out conditions down to 2.7V. |
| Endurance | 100,000 program/erase cycles; sufficient for field firmware updates over 10+ years in industrial gateways. |
| Data Retention | >100 years; ensures long-term reliability in unpowered storage for medical device calibration data. |
| Standby Current | 4 µA typical; reduces system power budget in battery-backed real-time clock modules. |
| Erase Times | Sector/Block: 18 ms typ; Chip: 35 ms typ-enables rapid full-image reprogramming in production test fixtures. |
| Write Protection | Hardware top-block protection (1FE000H–1FFFFFH) via WP# pin; prevents accidental overwrite of boot loader code. |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm) and 48-ball TFBGA (6 mm × 8 mm). Both packages conform to JEDEC standard x16 flash pin assignments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A20 | Address Inputs | A0–A19 select 2M words; A20 (AMS) used in command addressing for sector/block erase. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; latched internally during write; tri-stated when CE# or OE# high. |
| CE# | Chip Enable | Active-low chip select; device enters standby (4 µA) when high; required for all operations. |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; must be low with CE# for valid output. |
| WE# | Write Enable | Active-low control for write cycles; latches address/data edges; initiates internal program/erase timing. |
| WP# | Write Protect | Active-low hardware lock for top boot blocks (1FE000H–1FFFFFH); floating = unprotected (internal pull-up). |
| RST# | Reset Input | Active-low hardware reset; terminates ongoing erase/program and forces return to read mode. |
| RY/BY# | Ready/Busy Output | Open-drain status indicator; low = busy (erase/program in progress); requires external pull-up resistor. |
| VDD / VSS | Power / Ground | Single 2.7V–3.6V supply; dual VSS pins ensure noise immunity in high-speed read/write transitions. |
| NC | No Connect | Unbonded pins in both TSOP and TFBGA packages; must remain unconnected per design. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Cell Architecture | Split-gate + thick-oxide tunneling injector delivers stable 70 ns read time and fixed 18 ms erase time across full 100k-cycle life. |
| Erase-Suspend/Resume | Allows temporary halt of block erase to read/program other sectors-critical for real-time firmware patching without full reboot. |
| Security ID Space | 128-bit factory-programmed ID + 128-word user-programmable segment, locked permanently after programming to prevent tampering. |
| CFI Query Support | JEDEC-standard Common Flash Interface enables automatic driver detection and configuration in Linux/RTOS bootloaders. |
| Auto Low-Power Mode | Reduces active read current from 6 mA to 4 µA after valid read access-cuts power in infrequently polled configuration storage. |

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-EKE | Bottom-boot block protection (000000H–001FFFH); identical timing, voltage, and endurance specs. | Used where boot code resides in lowest memory region; incompatible pin-level replacement due to different protected address space. | Select only if bottom-boot architecture matches system memory map and bootloader location. |
| MX29LV320ETTI-70G | 32-Mbit x16, 70 ns, 2.7–3.6V; lacks Security ID and CFI; uses different command set and no erase-suspend. | Suitable for cost-sensitive consumer electronics where advanced features are unused; not recommended for secure or real-time update use cases. | Choose when basic firmware storage suffices and BOM cost reduction outweighs feature loss. |
Compared with SST39VF3201C-70-4I-EKE, the SST39VF3202C-70-4I-EKE provides top-boot protection essential for high-memory bootloaders, while MX29LV320ETTI-70G offers lower cost but omits security, suspend/resume, and standardized CFI-limiting portability and field-update robustness.

FAQ
What is the boot block protection scheme for SST39VF3202C-70-4I-EKE?
The SST39VF3202C-70-4I-EKE implements top-boot hardware block protection covering addresses 1FE000H–1FFFFFH (two 4-KWord blocks). When WP# is driven low, program and erase operations to this region are disabled. This protects critical boot code from accidental overwrite during firmware updates. The SST39VF3202C-70-4I-EKE differs from SST39VF3201C, which protects the bottom boot block instead.
Does SST39VF3202C-70-4I-EKE support simultaneous read and erase-suspend operations?
Yes, the SST39VF3202C-70-4I-EKE supports Erase-Suspend mode: issuing the B0H command halts an ongoing sector or block erase, allowing reads from unprotected regions or word-programming into non-suspended sectors. During suspend, DQ2 toggling indicates erase-suspended status, and DQ6 remains high. The SST39VF3202C-70-4I-EKE resumes erase upon receipt of the 30H resume command.
What package options are available for SST39VF3202C-70-4I-EKE?
The SST39VF3202C-70-4I-EKE is offered in two RoHS-compliant packages: 48-lead TSOP (12 mm × 20 mm) and 48-ball TFBGA (6 mm × 8 mm). Both adhere to JEDEC-standard x16 flash pinouts. The TSOP variant suits through-hole prototyping and legacy PCB layouts, while the TFBGA enables high-density routing in compact IoT edge nodes. Pin functions and timing are identical across packages.
How is end-of-write detection implemented in SST39VF3202C-70-4I-EKE?
The SST39VF3202C-70-4I-EKE provides three hardware-supported methods: Data# Polling (DQ7 toggles until completion, then outputs true data), Toggle Bit (DQ6 toggles during operation, stops when complete), and Ready/Busy# (RY/BY# open-drain output pulled low during write). RY/BY# requires an external 10–100 kΩ pull-up. All methods are valid after the rising edge of the final WE# pulse in the command sequence.
What Security ID capabilities does SST39VF3202C-70-4I-EKE provide?
The SST39VF3202C-70-4I-EKE includes a 136-word Security ID space: 128 bits factory-programmed by Microchip and 128 words user-programmable. Users enter Security ID mode via 88H command, program with A5H, and permanently lock with 85H. Once locked, no further writes are possible. Neither segment supports erase. The SST39VF3202C-70-4I-EKE uses this for anti-cloning and secure device authentication in regulated markets.
