Product details
Overview
SST39VF200A-70-4C-EKE-T from Microchip Technology is a 2 Mbit (128K × 16) CMOS Multi-Purpose Flash memory IC with JEDEC-standard x16 asynchronous interface, 70 ns read access time, 2.7–3.6 V single-supply operation, and SuperFlash® split-gate technology enabling 100,000 program/erase cycles and >100 years data retention. It serves as nonvolatile code/data storage in embedded controllers and firmware-updatable systems.
For engineers reviewing the SST39VF200A-70-4C-EKE-T datasheet, SST39VF200A-70-4C-EKE-T pinout, SST39VF200A-70-4C-EKE-T application, or SST39VF200A-70-4C-EKE-T equivalent, key selection criteria include its 48-pin TSOP package, sector/block-erase architecture, hardware/software write protection, CFI compliance, and industrial temperature support (–40°C to +85°C).
Technical Context
The SST39VF200A-70-4C-EKE-T implements an asynchronous x16 parallel interface with standard CE#/OE#/WE# control logic and latched address/data bus. Its SuperFlash® split-gate cell enables fixed erase/program timing independent of cycle count - unlike floating-gate alternatives - eliminating system-level de-rating over lifetime.
It supports three software-controlled erase modes (sector: 2 KWord, block: 32 KWord, chip-wide), Word-Program (14 µs typical), and dual end-of-write detection (DQ7 Data# Polling and DQ6 Toggle Bit). All operations conform to JEDEC-standard command sets and include CFI Query mode for automated device identification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2 Mbit (128K × 16 organization) - provides 256 KB of byte-addressable nonvolatile storage for boot code or configuration data. |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) in 14 MHz bus systems without wait states. |
| Supply Voltage | 2.7–3.6 V - supports wide-input industrial power rails and battery-backed operation down to 2.7 V. |
| Endurance | 100,000 program/erase cycles - ensures reliable field firmware updates across product lifecycle. |
| Data Retention | >100 years - guarantees long-term integrity of stored calibration, serial numbers, or security keys. |
| Erase Granularity | Uniform 2 KWord sectors and 32 KWord blocks - allows selective reprogramming without full-chip erasure. |

Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | A0–A15 select 128K words; A16 is most-significant address (AMS) for sector/block addressing per JEDEC. |
| DQ0–DQ15 | Data I/O | Bi-directional x16 data bus; outputs tri-stated when CE# or OE# is high; internally latched on write. |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 µA) when high; required low for all operations. |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; high disables outputs. |
| WE# | Write Enable | Active-low write strobe; latches address/data and initiates internal Program/Erase sequences. |
| VDD | Power Supply | 2.7–3.6 V supply; powers core logic and memory array; internal charge pump generates VPP for erase/program. |
| VSS | Ground | Signal and power ground reference; two dedicated pins ensure stable return path. |
| NC | No Connection | Pins 9, 10, 12–16, 25–28, 31, 33, 34, 36, 37, 40, 41, 43, 44, 46, 47 - unconnected; must be left floating or tied to VSS per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell with thick-oxide tunneling injector delivers fixed 14 µs program and 18 ms erase times across full endurance life - no timing drift or firmware adaptation required. |
| JEDEC-Compliant Command Set | Fully compatible with industry-standard flash command protocols (e.g., 6-byte erase, 3-byte program unlock), enabling drop-in replacement in legacy x16 systems. |
| Hardware + Software Write Protection | Combines noise/glitch immunity (<5 ns pulse rejection), VDD power-up/down detection (<1.5 V inhibit), and mandatory 3-byte SDP unlock sequence - prevents accidental corruption during brown-out or reset. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF200A-70-4C-EKE | Same die, identical specs, but shipped in tape-and-reel (EKE) vs. tray (EKE-T); no functional difference. | No application impact - both support same PCB footprint and thermal profile. | Select EKE-T for manual prototyping or low-volume assembly; EKE for automated SMT lines. |
| MX29LV200CTTC-70G | 2 Mbit x16, 70 ns, 2.7–3.6 V, but uses conventional floating-gate architecture - slower erase (500 ms chip-erase), lower endurance (10,000 cycles), no CFI support. | Not suitable for frequent field updates or CFI-dependent bootloaders; requires longer timeout handling in firmware. | Choose only if legacy design compatibility or cost sensitivity outweighs longevity and feature requirements. |
Compared with SST39VF200A-70-4C-EKE-T, the EKE variant offers identical electrical and timing behavior with packaging optimized for SMT placement, while MX29LV200CTTC-70G trades endurance, erase speed, and CFI capability for broader distributor availability - making SST39VF200A-70-4C-EKE-T optimal for long-life, upgradable embedded systems.

FAQ
What is the maximum operating temperature range for the SST39VF200A-70-4C-EKE-T?
The SST39VF200A-70-4C-EKE-T is rated for industrial operation from –40°C to +85°C. This specification is validated per Microchip's DS25001A datasheet and applies to all DC and AC parameters under 2.7–3.6 V supply. The device maintains full functionality-including 70 ns read access, 14 µs Word-Program, and 18 ms sector-erase-across this full range, making it suitable for deployment in harsh environments such as factory floors or vehicle under-hood locations. SST39VF200A-70-4C-EKE-T does not require derating at temperature extremes.
Does the SST39VF200A-70-4C-EKE-T support Common Flash Interface (CFI)?
Yes, the SST39VF200A-70-4C-EKE-T fully supports CFI Query mode per JEDEC JESD68. Writing the 3-byte sequence (0x5555/0xAA, 0x2AAA/0x55, 0x5555/0x98) enters CFI mode, allowing readout of standardized geometry, timing, and command-set descriptors from addresses 0x10–0x34. This enables automatic driver initialization in Linux MTD or U-Boot environments. SST39VF200A-70-4C-EKE-T CFI data confirms 128K × 16 organization, 2.7–3.6 V VDD range, and 70 ns max access time - all matching its datasheet specifications.
How many program/erase cycles is the SST39VF200A-70-4C-EKE-T guaranteed for?
The SST39VF200A-70-4C-EKE-T is guaranteed for 100,000 program/erase cycles per sector, as specified in Microchip's DS25001A datasheet. This endurance rating is achieved using SuperFlash® split-gate technology, which maintains consistent 14 µs Word-Program and 18 ms sector-erase times across all cycles - unlike floating-gate alternatives whose timing degrades with usage. SST39VF200A-70-4C-EKE-T endurance is tested per JEDEC standard JESD22-A117 and applies across the full industrial temperature range.
What package type is used by the SST39VF200A-70-4C-EKE-T?
The SST39VF200A-70-4C-EKE-T uses a 48-lead TSOP (Thin Small Outline Package) with 12 mm × 20 mm body dimensions and standard JEDEC MO-141AC footprint. Pin 1 is marked by a notch or dot; the package is RoHS-compliant and lead-free. It is mechanically and electrically identical to the SST39VF200A-70-4C-EKE variant - differing only in packaging format (tape-and-reel vs. tray). SST39VF200A-70-4C-EKE-T is compatible with standard TSOP reflow profiles, including peak solder temperature of 260°C for 10 seconds.
What voltage range is required for programming and erasing the SST39VF200A-70-4C-EKE-T?
The SST39VF200A-70-4C-EKE-T requires a supply voltage of 2.7–3.6 V for all operations - including read, program, and erase - with no external VPP needed. Internal charge pump circuitry generates the high-voltage pulses required for Fowler-Nordheim tunneling. This single-supply operation simplifies power design versus older flash devices requiring separate 12 V VPP. SST39VF200A-70-4C-EKE-T remains fully functional down to 2.7 V, supporting battery-backed or wide-input industrial power supplies without external regulation overhead.
