Product details
Overview
SST39VF200A-70-4I-B3KE 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 reliable nonvolatile storage for firmware, configuration, and boot code in industrial embedded systems requiring extended temperature support.
For engineers reviewing the SST39VF200A-70-4I-B3KE datasheet, SST39VF200A-70-4I-B3KE pinout, SST39VF200A-70-4I-B3KE application, or SST39VF200A-70-4I-B3KE equivalent, key selection criteria include its 2.7 V minimum VDD, -40°C to +85°C industrial temperature rating, 100,000 program/erase cycles, uniform 2 KWord sector erase, and SuperFlash® technology enabling fixed 14 µs word-program timing independent of wear.
Technical Context
This device implements SST's proprietary SuperFlash® split-gate cell architecture with thick-oxide tunneling injector, delivering superior endurance and data retention (>100 years) versus conventional flash. It supports standard JEDEC command sets-including Software Data Protection (SDP) via six-byte sequences-and provides dual end-of-write detection via DQ7 Data# Polling and DQ6 Toggle Bit.
It operates exclusively in asynchronous x16 mode with latched address/data, no internal clock, and hardware write inhibit during power transitions. Sector-, block-, and chip-erase are all supported, with uniform 2 KWord sectors and 32 KWord blocks mapped using AMS–A11 (sector) or AMS–A15 (block) address lines, where AMS = A16 for this 2 Mbit variant.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF200A-70-4C-B3KE | Same die, commercial temperature grade (0°C to +70°C) instead of industrial (-40°C to +85°C) | Not qualified for extended ambient or under-hood automotive use | Select when cost sensitivity outweighs thermal robustness requirements |
| MX29LV200CTTI-70G | 2 Mbit x16, 70 ns, 3.0–3.6 V; uses different command set and lacks CFI support | Requires custom driver adaptation; no automatic parameter discovery | Choose only if legacy design already uses Macronix-compatible firmware stack |
Compared with SST39VF200A-70-4C-B3KE, the -4I variant adds guaranteed operation down to -40°C and higher reliability screening; compared with MX29LV200CTTI-70G, SST39VF200A-70-4I-B3KE offers CFI compatibility and fixed-program timing-reducing driver complexity and eliminating wear-based timing drift.

FAQ
What is the operating temperature range for SST39VF200A-70-4I-B3KE?
The SST39VF200A-70-4I-B3KE is rated for industrial temperature operation from -40°C to +85°C. This specification is guaranteed across the full 2.7–3.6 V supply range and applies to all functional modes - read, program, and erase. The 'I' suffix in the part number explicitly denotes industrial grade, distinguishing it from the commercial-grade SST39VF200A-70-4C-B3KE.
Does SST39VF200A-70-4I-B3KE require an external VPP voltage for programming?
No, SST39VF200A-70-4I-B3KE does not require an external VPP voltage. It performs all program and erase operations using only the 2.7–3.6 V VDD supply, thanks to on-chip charge pump circuitry. This eliminates the need for a separate high-voltage rail and simplifies PCB design - a key advantage of SST's SuperFlash® technology implemented in the SST39VF200A-70-4I-B3KE.
How many erase sectors does SST39VF200A-70-4I-B3KE have, and what is their size?
The SST39VF200A-70-4I-B3KE contains 64 uniform erase sectors, each sized at 2 KWords (4 KB). This is confirmed by CFI Query Table 7 (address 2DH–30H), where y = 63 yields 64 sectors and z = 16 yields 4 KB per sector. Sector addressing uses AMS–A11 (A16–A11), enabling precise, non-disruptive firmware updates without erasing the entire device.
Is SST39VF200A-70-4I-B3KE pin-compatible with SST39LF200A-70-4I-B3KE?
Yes, SST39VF200A-70-4I-B3KE is pin-compatible with SST39LF200A-70-4I-B3KE in the same package (e.g., 48-lead TSOP), sharing identical pinout, signal definitions, and x16 interface. However, they differ in supply voltage: SST39VF200A-70-4I-B3KE operates from 2.7–3.6 V, while SST39LF200A-70-4I-B3KE requires 3.0–3.6 V. System designers must verify VDD compliance before substitution.
What command sequence is required to perform a sector erase on SST39VF200A-70-4I-B3KE?
To perform a sector erase on SST39VF200A-70-4I-B3KE, execute the JEDEC-standard six-byte command sequence: write 0xAA to address 0x5555, 0x55 to 0x2AAA, 0x80 to 0x5555, 0xAA to 0x5555, 0x55 to 0x2AAA, then 0x30 to the target sector address. The sector address is latched on the falling edge of the sixth WE# pulse. This sequence is mandatory due to Software Data Protection and applies identically across all SST39VF200A-70-4I-B3KE operations.
