Product details
Overview
SST39VF200A-70-4C-M1QE from Microchip Technology is a 2 Mbit (128K × 16) CMOS Multi-Purpose Flash memory IC using SuperFlash technology, operating at 2.7–3.6 V with 70 ns read access time, 14 µs word-program time, and JEDEC-standard x16 asynchronous interface. It serves as nonvolatile program/data storage in embedded controllers, BIOS firmware, and industrial HMI systems.
For engineers reviewing the SST39VF200A-70-4C-M1QE datasheet, SST39VF200A-70-4C-M1QE pinout, SST39VF200A-70-4C-M1QE application, or SST39VF200A-70-4C-M1QE equivalent, key selection criteria include voltage range compatibility (2.7–3.6 V), TSOP-48 package footprint, sector/block-erase architecture, CFI support, and hardware/software data protection for reliable firmware updates.
Technical Context
This device implements a split-gate SuperFlash cell with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count-unlike conventional flash-and eliminating system-level de-rating over lifetime. Its command-set architecture follows JEDEC-standard x16 pinouts and supports Software Data Protection (SDP) via 3-byte (program) and 6-byte (erase) sequences.
Operation modes are controlled by CE#, OE#, and WE# with strict timing dependencies: address latching occurs on the falling edge of the last of CE#/WE#, while data latching occurs on the rising edge of the first of CE#/WE#. End-of-write detection uses DQ7 (Data# Polling) and DQ6 (Toggle Bit), both validated after the fourth (program) or sixth (erase) WE# pulse.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV200CTTI-70G | 3.0–3.6 V only; no 2.7 V support; 70 ns access; same 2 Mbit x16 density and TSOP-48 package | Lacks industrial temperature grade (-40°C to +85°C); rated only for commercial (0°C to +70°C) | Select when system operates exclusively within commercial temp range and 3.0 V minimum rail is guaranteed |
| EN29LV200T-70IP | 2.7–3.6 V compatible; 70 ns access; identical 2 Mbit x16 organization and TSOP-48 footprint | Uses different SDP command sequence; lacks CFI support; no official product ID query mode | Choose only if firmware loader is pre-validated for EN29LV command set and CFI auto-detection is unnecessary |
Compared with SST39VF200A-70-4C-M1QE, MX29LV200CTTI-70G offers identical speed and density but restricts voltage and temperature flexibility, while EN29LV200T-70IP matches electrical specs yet requires custom driver adaptation due to missing CFI and divergent protection commands.

FAQ
What is the operating voltage range for SST39VF200A-70-4C-M1QE?
The SST39VF200A-70-4C-M1QE operates across a 2.7–3.6 V supply range, supporting both commercial (0°C to +70°C) and industrial (-40°C to +85°C) temperature grades. This dual-range capability enables use in battery-backed systems and wide-input power supplies where 3.0 V minimum cannot be guaranteed. The SST39VF200A-70-4C-M1QE does not support 3.0–3.6 V-only operation like its SST39LF counterpart.
Does SST39VF200A-70-4C-M1QE support Common Flash Interface (CFI)?
Yes, the SST39VF200A-70-4C-M1QE implements full CFI compliance per JEDEC JESD68. Entering CFI Query mode requires writing 0x98 to address 0x5555, after which geometry, timing, and command-set parameters can be read from standardized offsets. This enables automatic driver detection in U-Boot, Linux MTD, and other open-source firmware stacks - a key advantage over non-CFI alternatives like EN29LV200T-70IP.
How many erase sectors and blocks does SST39VF200A-70-4C-M1QE have?
The SST39VF200A-70-4C-M1QE contains 64 uniform sectors of 2 KWords (4 KB each) and 4 uniform blocks of 32 KWords (64 KB each). Sector-erase time is 18 ms typical, block-erase time is also 18 ms typical, and chip-erase completes in 70 ms typical. These fixed durations - guaranteed across all 100,000 program/erase cycles - eliminate need for dynamic timeout scaling in host firmware.
What package type is used for SST39VF200A-70-4C-M1QE?
The SST39VF200A-70-4C-M1QE is supplied in a 48-lead TSOP (Thin Small Outline Package) measuring 12 mm × 20 mm, with standard lead pitch and RoHS-compliant finish. Pinout conforms to JEDEC MO-141AC, ensuring mechanical and electrical compatibility with legacy PCB footprints designed for x16 parallel flash. No TFBGA, WFBGA, or XFLGA variants are assigned to this specific part number.
How is write completion detected on SST39VF200A-70-4C-M1QE?
Write completion on SST39VF200A-70-4C-M1QE is detected using two hardware-supported methods: Data# Polling (DQ7 toggles complement state until operation completes, then returns true data) and Toggle Bit (DQ6 alternates logic states during operation, then stabilizes). Both are valid after the fourth WE# pulse for programming and sixth WE# pulse for erasing - enabling deterministic polling loops without fixed delays in host firmware.
