Product details
Overview
SST39VF200A-70-4I-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-70-4I-M1QE datasheet, SST39VF200A-70-4I-M1QE pinout, SST39VF200A-70-4I-M1QE application, or SST39VF200A-70-4I-M1QE equivalent, key selection criteria include voltage range compatibility (2.7–3.6 V), TSOP-48 package footprint, sector/block-erase architecture, and software data protection compliance for secure firmware updates.
Technical Context
This device implements a split-gate SuperFlash cell with thick-oxide tunneling injector for enhanced reliability and fixed erase/program timing independent of cycle count. Its command-set architecture follows JEDEC-standard pinouts and supports Software Data Protection (SDP) via six-byte sequences for erase and three-byte sequences for program operations.
It features dual end-of-write detection (DQ7 Data# Polling and DQ6 Toggle Bit), hardware write inhibit during power transitions, and CFI Query mode for runtime device identification. The 2 KWord uniform sectors (64 total) and 32 KWord uniform blocks (4 total) enable granular firmware partitioning without full-chip erasure.

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 | Commercial temperature grade (0°C to +70°C) vs. industrial (-40°C to +85°C); identical electrical specs and pinout | Not rated for extended thermal environments; unsuitable for under-hood or outdoor industrial enclosures | Select only for cost-sensitive indoor applications with controlled ambient temperature |
| MX29LV200CTTI-70G | 3.0–3.6 V supply only; 70 ns access; 48-pin TSOP; lacks CFI Query mode and uses different SDP command set | Requires custom driver adaptation; no runtime geometry auto-detection; lower endurance (100K cycles same, but retention rated at 20 years) | Use only when legacy design migration mandates pin-compatible replacement without firmware changes |
Compared with SST39VF200A-70-4I-M1QE, the -4C variant trades industrial temperature support for lower cost, while MX29LV200CTTI-70G requires driver-level redesign due to missing CFI and divergent command protocol - making SST39VF200A-70-4I-M1QE optimal for new designs needing guaranteed long-term retention and standardized firmware update workflows.

FAQ
What is the operating temperature range for SST39VF200A-70-4I-M1QE?
The SST39VF200A-70-4I-M1QE is rated for industrial temperature operation from –40°C to +85°C, validated across its full 2.7–3.6 V supply range. This makes it suitable for deployment in harsh environments such as factory automation controllers and outdoor kiosks where ambient conditions exceed commercial-grade limits. The device maintains specified read access time (70 ns), program time (14 µs), and erase timing (18 ms) across this full range.
Does SST39VF200A-70-4I-M1QE support JEDEC-standard command sets?
Yes, SST39VF200A-70-4I-M1QE fully complies with JEDEC Standard JESD21-C for Flash EEPROM pinouts and command sets. It implements the standard three-byte software unlock sequence for program operations and six-byte sequence for erase functions. Additionally, it supports Common Flash Interface (CFI) Query mode (entry via 5555H/AAH → 2AAAH/55H → 5555H/98H), enabling automatic driver detection and geometry reporting per JEDEC JESD68.
How many erase sectors and blocks does SST39VF200A-70-4I-M1QE provide?
SST39VF200A-70-4I-M1QE provides 64 uniform 2 KWord sectors (totaling 128K words) and 4 uniform 32 KWord blocks. Sector size equals 4 KB (2 KWord × 2 bytes), block size equals 64 KB (32 KWord × 2 bytes). This architecture is confirmed in Table 7 of DS25001A and enables selective firmware updates - for example, modifying only the communication stack without affecting bootloader or calibration tables stored in separate sectors.
What write protection mechanisms does SST39VF200A-70-4I-M1QE implement?
SST39VF200A-70-4I-M1QE implements dual-layer write protection: hardware-level inhibition (VDD power-up/down detection, sub-5 ns noise rejection, and OE#/CE#/WE# state monitoring) and software-level JEDEC-compliant Software Data Protection (SDP). SDP requires valid three-byte unlock sequences before programming and six-byte sequences before any erase operation, preventing accidental writes during system initialization or transient faults.
Is SST39VF200A-70-4I-M1QE pin-compatible with SST39LF200A variants?
Yes, SST39VF200A-70-4I-M1QE shares identical pinout, package dimensions, and signal definitions with SST39LF200A-70-4I-M1QE and other members of the SST39LF/VF200A family. Both use 48-lead TSOP with matching A0–A16, DQ0–DQ15, CE#, OE#, WE#, VDD, and VSS assignments. However, voltage ranges differ: SST39VF200A operates at 2.7–3.6 V, while SST39LF200A requires 3.0–3.6 V - direct substitution requires verification of system supply stability at 2.7 V minimum.
