Product details
Overview
SST39VF200A-70-4I-M1QE-T from Microchip Technology is a 2 Mbit (128K × 16) CMOS Multi-Purpose Flash memory IC with x16 asynchronous interface, 70 ns read access time, 2.7–3.6 V single-supply operation, and JEDEC-standard pinout. It delivers high reliability (100,000 program/erase cycles, >100 years data retention) for firmware storage in industrial microcontroller systems.
For engineers reviewing the SST39VF200A-70-4I-M1QE-T datasheet, SST39VF200A-70-4I-M1QE-T pinout, SST39VF200A-70-4I-M1QE-T application, or SST39VF200A-70-4I-M1QE-T equivalent, this page provides verified technical context, JEDEC-compliant pin functions, SuperFlash-specific timing behavior, sector/block erase architecture, and validated alternative flash parts for embedded system design and BOM optimization.
Technical Context
The SST39VF200A-70-4I-M1QE-T implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. It supports standard JEDEC command sets including Software Data Protection (SDP) with three-byte unlock sequences for programming and six-byte sequences for sector/block/chip erase.
It operates in asynchronous x16 mode with latched address/data, uses DQ6 (Toggle Bit) and DQ7 (Data# Polling) for end-of-write detection, and features hardware write inhibit via CE#/OE#/WE# logic states - all compliant with industry-standard flash memory interfaces for seamless integration into legacy 16-bit bus architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 2 Mbit (128K × 16), directly maps to 256 KB of 16-bit addressable space for boot code or configuration storage. |
| Read Access Time | 70 ns - determines maximum sustained read throughput on 16-bit parallel buses without wait states at ≤14 MHz. |
| Supply Voltage Range | 2.7–3.6 V - enables direct interfacing with 3.3 V logic and compatibility with wide-input industrial power rails. |
| Endurance | 100,000 program/erase cycles - supports field firmware updates over product lifetime without wear leveling. |
| Data Retention | Greater than 100 years - ensures nonvolatile storage integrity across extended deployment in unpowered conditions. |
| Erase Architecture | Uniform 2 KWord sectors (64 total) and 32 KWord blocks (4 total) - allows granular firmware patching and full-image reprogramming. |
| Write Timing | 14 µs word-program time; 18 ms sector/block-erase time - enables fast in-system updates with predictable latency. |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, surface-mountable with standard reflow profile (260°C/10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A16 | Address Inputs | A0–A15 select 128K words; A16 selects upper/lower half of 256 KB space - matches JEDEC x16 addressing. |
| DQ0–DQ15 | Data I/O | Bi-directional 16-bit data bus; outputs tri-stated when CE# or OE# high - enables shared bus arbitration. |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 µA) when high - critical for multi-device memory decoding. |
| OE# | Output Enable | Active-low output gate; controls data bus visibility during read - decouples read timing from chip selection. |
| WE# | Write Enable | Active-low write control; initiates SDP command latching and internal program/erase - defines write cycle boundaries. |
| VDD | Power Supply | 2.7–3.6 V supply; powers core logic and SuperFlash array - no external VPP required due to internal charge pump. |
| VSS | Ground | Two dedicated ground pins (pins 23 and 48) - reduces noise coupling and improves signal integrity on high-speed reads. |
| NC | No Connect | Pins 9, 10, 12–16, 18, 19, 21, 22, 24, 25, 27, 29, 31, 33, 35, 37, 39, 41, 43, 45, 47 - must remain unconnected per design. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide injector enables fixed 14 µs program and 18 ms erase times - eliminates software de-rating over lifetime. |
| JEDEC Standard Compliance | Pinout, command set, and timing fully match JEDEC publication 100 - ensures drop-in replacement in existing x16 flash designs. |
| Software Data Protection | Three-byte unlock sequence required before programming; six-byte sequence for erase - prevents accidental writes during power transitions. |
| End-of-Write Detection | DQ6 Toggle Bit and DQ7 Data# Polling provide real-time status without polling overhead - simplifies host driver implementation. |
| Low Power Standby | 3 µA typical standby current at 14 MHz - extends battery life in portable or energy-constrained industrial devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF200A-70-4C-M1QE-T | Commercial temperature grade (0°C to +70°C) vs. industrial (-40°C to +85°C); identical electrical specs and pinout. | Not rated for extended temperature operation - unsuitable for outdoor, automotive, or factory-floor deployments. | Select only for cost-sensitive consumer-grade applications with controlled ambient conditions. |
| MX29LV200CTTI-70G | 2 Mbit x16 flash with 70 ns access, but uses different command set (non-JEDEC), lacks CFI support, and has higher 5 mA standby current. | Requires custom driver adaptation; no built-in Data# Polling/Toggle Bit - increases host CPU overhead during writes. | Use only if legacy board design already implements Macronix-specific protocol and thermal range permits. |
Compared with SST39VF200A-70-4I-M1QE-T, the commercial-grade SST39VF200A-70-4C-M1QE-T sacrifices industrial temperature tolerance for lower cost, while MX29LV200CTTI-70G requires firmware changes and offers inferior power efficiency and standardization - making the original part optimal for new industrial designs requiring plug-and-play JEDEC compliance and long-term reliability.
