Product details
Overview
SST39VF800A-70-4I-M1QE-T from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC using SuperFlash technology, supporting single-supply 2.7–3.6 V operation, 70 ns read access time, sector/block erase, and word-program with 100,000-cycle endurance. It serves as nonvolatile program/data storage in industrial microcontroller boot loaders.
For engineers reviewing the SST39VF800A-70-4I-M1QE-T datasheet, SST39VF800A-70-4I-M1QE-T pinout, SST39VF800A-70-4I-M1QE-T application, or SST39VF800A-70-4I-M1QE-T equivalent, key selection criteria include voltage range compatibility (2.7–3.6 V), TSOP-48 package footprint, JEDEC x16 pinout compliance, and support for Data# Polling/Toggle Bit write status detection.
Technical Context
This device implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program timing independent of cycle count-unlike conventional flash technologies where timing degrades over endurance life. It uses standard asynchronous x16 interface timing with CE#, OE#, and WE# control signals.
Command execution follows JEDEC-standard six-byte sequences for sector/block/chip erase and three-byte sequences for word-program, all initiated via address/data latching on WE#/CE# edges. Internal VPP generation eliminates external high-voltage requirements, and hardware/software data protection prevents inadvertent writes during power transitions.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-70-4C-M1QE-T | 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 in harsh environments | Select only for cost-sensitive consumer or lab-grade designs with controlled ambient conditions |
| MX29LV800CTTI-70G | 8 Mbit x16, 70 ns, 2.7–3.6 V, but uses different command set and lacks CFI support; requires firmware adaptation | Requires modified bootloader driver due to non-JEDEC-compatible erase/write commands | Choose only when existing design already uses Macronix parts and migration effort is justified by supply chain constraints |
Compared with SST39VF800A-70-4I-M1QE-T, the SST39VF800A-70-4C-M1QE-T offers identical functionality at lower cost but sacrifices industrial temperature resilience, while MX29LV800CTTI-70G demands firmware changes despite matching density and speed-making the original part optimal for new industrial designs requiring drop-in reliability and standardized CFI auto-detection.

FAQ
What is the operating temperature range for SST39VF800A-70-4I-M1QE-T?
The SST39VF800A-70-4I-M1QE-T is rated for industrial temperature operation from -40°C to +85°C, making it suitable for deployment in harsh environments such as factory automation, outdoor networking gear, and vehicle under-hood electronics where thermal stability is critical. This specification is confirmed in the DS25001A datasheet Section "Operating Range: SST39VF200A/400A/800A".
Does SST39VF800A-70-4I-M1QE-T support Common Flash Interface (CFI)?
Yes, SST39VF800A-70-4I-M1QE-T supports CFI mode via the standard JEDEC query command sequence (5555H/AAH → 2AAAH/55H → 5555H/98H), allowing host systems to automatically detect device geometry, timing parameters, and command set. This feature is documented in Table 5 and Section "Common Flash Memory Interface (CFI)" of the DS25001A datasheet.
How many erase sectors does SST39VF800A-70-4I-M1QE-T have?
The SST39VF800A-70-4I-M1QE-T contains 256 uniform sectors of 2 KWords (4 KB) each, totaling 8 Mbit capacity. This is explicitly defined in Table 9 ("Device Geometry Information for SST39LF/VF800A") where y = 00FFH (255), so y + 1 = 256 sectors, and z = 0010H (16), meaning 16 × 256 B = 4 KB per sector.
What is the maximum word-program time for SST39VF800A-70-4I-M1QE-T?
The typical word-program time for SST39VF800A-70-4I-M1QE-T is 14 µs, with a maximum timeout of 32 µs (2¹ × 2⁴ µs) as specified in Table 6 ("System Interface Information"). This value is consistent across all SST39VF200A/400A/800A variants and reflects the fixed timing inherent to SuperFlash technology.
Is SST39VF800A-70-4I-M1QE-T pin-compatible with SST39LF800A-70-4I-M1QE-T?
No - although both share the same 48-pin TSOP package and x16 interface, SST39VF800A-70-4I-M1QE-T uses A0–A17 for addressing (with A18 reserved for block erase), while SST39LF800A requires 3.0–3.6 V supply and has different VDD min/max specifications. Their command sets are identical, but voltage domain mismatch prevents direct substitution without power rail redesign.
