Product details
Overview
SST39VF200A-70-4I-MAQE from Microchip Technology is a 2 Mbit (128K × 16) CMOS Multi-Purpose Flash memory IC using SuperFlash technology, designed for nonvolatile program/data storage in embedded systems. It operates from 2.7–3.6 V, delivers 70 ns read access time, supports sector/block erase, and features JEDEC-standard x16 asynchronous interface - used in industrial control firmware updates and boot code storage.
For engineers reviewing the SST39VF200A-70-4I-MAQE datasheet, SST39VF200A-70-4I-MAQE pinout, SST39VF200A-70-4I-MAQE application, or SST39VF200A-70-4I-MAQE equivalent, key selection criteria include its 2.7 V minimum VDD operation, 100,000-cycle endurance, uniform 2 KWord sectors, toggle-bit/data# polling write status detection, and TSOP-48 package compatibility with legacy x16 memory interfaces.
Technical Context
The SST39VF200A-70-4I-MAQE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its command-set-driven operation uses standard microprocessor write sequences with six-byte software data protection for erase and three-byte for program.
It supports three erase granularities - sector (2 KWord), block (32 KWord), and chip - all initiated via JEDEC-compliant command sequences latched on WE#/CE# edges. Write completion is verified via DQ6 (Toggle Bit) or DQ7 (Data# Polling), with no external VPP required due to internal charge pump generation.

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-MAQE | 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 under-hood or outdoor deployments | Select for cost-sensitive consumer electronics where ambient temperature remains controlled |
| MX29LV200CTTI-70G | 3.0–3.6 V supply only; lacks 2.7 V low-voltage support; same 2 Mbit x16 density and 70 ns access | Requires stable 3.3 V rail; incompatible with brown-out tolerant designs | Choose when existing board uses 3.3 V ±5% regulation and no low-VDD margin is needed |
Compared with SST39VF200A-70-4I-MAQE, the SST39VF200A-70-4C-MAQE offers identical functionality at lower cost but sacrifices industrial temperature range, while MX29LV200CTTI-70G provides equivalent density and speed but removes 2.7 V operation - limiting use in battery-powered or wide-input-range systems.

FAQ
What is the exact memory organization of the SST39VF200A-70-4I-MAQE?
The SST39VF200A-70-4I-MAQE is organized as 128K words × 16 bits, totaling 2 Mbit (256 KB) of storage. Each word is accessed via A0–A16 address lines, with A16 acting as the most significant address bit for the 2 Mbit map. This x16 configuration requires a 16-bit data bus and is JEDEC-standard compliant for parallel flash interfaces.
Does the SST39VF200A-70-4I-MAQE require an external VPP voltage for programming or erasing?
No, the SST39VF200A-70-4I-MAQE does not require an external VPP voltage. It integrates an internal charge pump that generates the high voltage needed for erase and program operations from the standard 2.7–3.6 V VDD supply. This eliminates the need for additional power rails or voltage translators in the system design.
How is write completion detected on the SST39VF200A-70-4I-MAQE?
Write completion on the SST39VF200A-70-4I-MAQE is detected using two software methods: Data# Polling (DQ7) and Toggle Bit (DQ6). During program or 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.
What package type is used for the SST39VF200A-70-4I-MAQE?
The SST39VF200A-70-4I-MAQE uses a 48-lead TSOP (Thin Small Outline Package) with 12 mm × 20 mm body dimensions and standard lead pitch. It is RoHS-compliant, lead-free, and qualified for surface-mount reflow up to 260°C for 10 seconds - matching JEDEC J-STD-020 requirements.
Is the SST39VF200A-70-4I-MAQE compatible with the Common Flash Interface (CFI)?
Yes, the SST39VF200A-70-4I-MAQE supports CFI mode. Entering CFI Query mode requires writing the sequence 5555H/AAH → 2AAAH/55H → 5555H/98H. Once entered, CFI data (including geometry, timing, and command set) is readable from predefined addresses per JEDEC standard, enabling auto-configuration in generic flash drivers.
