Product details
Overview
SST39VF200A-70-4C-MAQE-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 100,000 program/erase cycles and >100 years data retention for embedded firmware storage in industrial control systems.
For engineers reviewing the SST39VF200A-70-4C-MAQE-T datasheet, SST39VF200A-70-4C-MAQE-T pinout, SST39VF200A-70-4C-MAQE-T application, or SST39VF200A-70-4C-MAQE-T equivalent, this page provides verified pin functions, sector/block erase timing, SuperFlash reliability metrics, and direct alternatives for legacy flash replacement in space-constrained designs.
Technical Context
The SST39VF200A-70-4C-MAQE-T implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of wear. It supports standard JEDEC command sets including Software Data Protection (SDP) with three-byte unlock sequences for word-program and six-byte sequences for sector/block/chip-erase.
It features dual end-of-write detection via Toggle Bit (DQ6) and Data# Polling (DQ7), latched address/data bus, and hardware write inhibit during power-up/down. The device operates across commercial (0°C to +70°C) and industrial (–40°C to +85°C) temperature ranges with 2.7–3.6 V supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF200A-70-4I-MAQE-T | Same die, industrial-grade temperature range (–40°C to +85°C) vs. commercial (0°C to +70°C) | Required for automotive, outdoor, or extended-temperature deployments where ambient exceeds 70°C | Select when full industrial temp rating is mandatory; otherwise SST39VF200A-70-4C-MAQE-T suffices for cost-sensitive commercial use |
| MX29LV200CTTI-70G | 2 Mbit x16 flash with 70 ns access, but uses different command set (no CFI); 3.0–3.6 V only; no 2.7 V support | Lacks low-voltage operation and standardized CFI query - requires custom driver adaptation | Use only if existing design already uses Macronix-compatible firmware; not drop-in due to command incompatibility and voltage range mismatch |
Compared with SST39VF200A-70-4I-MAQE-T, the -4C variant trades temperature margin for lower cost in benign environments; compared with MX29LV200CTTI-70G, it offers broader voltage compatibility and standardized CFI support-critical for portable or multi-vendor firmware ecosystems.

FAQ
What is the memory organization of the SST39VF200A-70-4C-MAQE-T?
The SST39VF200A-70-4C-MAQE-T is organized as 128K × 16, delivering 2 Mbit (256 KB) of x16 asynchronous flash memory. Its address space spans A0–A16 (17 address lines), with A0–A15 selecting individual 16-bit words and A16 enabling bank selection. This structure matches JEDEC-standard x16 flash interfaces and supports direct connection to 16-bit microcontroller buses without glue logic.
Does the SST39VF200A-70-4C-MAQE-T support CFI (Common Flash Interface)?
Yes, the SST39VF200A-70-4C-MAQE-T fully supports CFI mode. Entering CFI Query mode requires writing the sequence 5555H/AAH → 2AAAH/55H → 5555H/98H. Once entered, CFI data-including device geometry, voltage ranges, and timeout values-is readable at standardized offsets (e.g., 10H–12H returns "QRY"). This enables auto-detection and generic flash driver compatibility in bootloader and OS environments.
What are the valid supply voltage ranges for programming the SST39VF200A-70-4C-MAQE-T?
The SST39VF200A-70-4C-MAQE-T requires 2.7–3.6 V for all operations-including read, program, and erase. Unlike the SST39LF series (3.0–3.6 V), this VF variant guarantees full functionality down to 2.7 V, making it suitable for battery-powered or brown-out-prone systems. Operation below 2.7 V disables write functionality and triggers hardware write inhibit to prevent corruption.
How does the SST39VF200A-70-4C-MAQE-T handle write completion detection?
The SST39VF200A-70-4C-MAQE-T provides two software-controlled methods: Data# Polling (DQ7) and Toggle Bit (DQ6). During program/erase, DQ7 returns complemented data until completion, then true data; DQ6 toggles between 0 and 1 until completion, then holds steady. Both are valid after the fourth (program) or sixth (erase) WE# pulse rising edge, enabling efficient polling without fixed delays.
Is the SST39VF200A-70-4C-MAQE-T pin-compatible with other SST39VF family members?
Yes, the SST39VF200A-70-4C-MAQE-T shares identical pinout and command set with SST39VF400A and SST39VF800A in the same package (e.g., 48-ball TFBGA), differing only in density and address line usage (A17/A18 are NC on the 2 Mbit variant). This allows footprint reuse and scalable BOM management-designers can drop in higher-density variants without PCB changes, provided firmware handles extended address space.
