Product details
Overview
SST39VF800A-70-4I-M1QE from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC with x16 asynchronous interface, 2.7–3.6V single-supply operation, 70 ns read access time, and JEDEC-standard pinout. It implements SST's SuperFlash technology with split-gate cells for high reliability in embedded firmware storage applications.
For engineers reviewing the SST39VF800A-70-4I-M1QE datasheet, SST39VF800A-70-4I-M1QE pinout, SST39VF800A-70-4I-M1QE application, or SST39VF800A-70-4I-M1QE equivalent, this page delivers verified specifications, TSOP-48 pin mapping, sector/block erase timing, endurance/reliability data, and direct alternative part comparisons for industrial firmware update systems.
Technical Context
The SST39VF800A-70-4I-M1QE uses SuperFlash split-gate cell architecture with thick-oxide tunneling injector, enabling fixed 14 µs word-program and 18 ms sector/block-erase times independent of program/erase cycle count. It supports JEDEC-standard command sets including Software Data Protection (SDP) and Common Flash Interface (CFI) query mode.
It operates in three primary modes: Read (CE# & OE# low), Word-Program (CE# low, WE# low, OE# high), and Erase (Sector/Block/Chip via six-byte command sequences). End-of-write detection is implemented via DQ7 Data# Polling and DQ6 Toggle Bit, both valid after the sixth WE# pulse for erase operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16), providing 1 MB of nonvolatile storage for boot code or configuration data |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) in 14 MHz bus systems without wait states |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V logic rails and tolerant of brown-out conditions down to 2.7 V |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-70-4C-M1QE | Commercial temperature range (0°C to +70°C); identical electrical specs and pinout | Not rated for industrial ambient extremes; unsuitable for outdoor or under-hood deployments | Select only for cost-sensitive consumer electronics where ambient stays within 0–70°C |
| MX29LV800CTTI-70G | 8 Mbit x16, 70 ns, 2.7–3.6 V, but uses different command set and lacks CFI support | Requires custom driver adaptation; no auto-detection capability; lower 100k-cycle endurance confirmed | Use only when legacy board design mandates Macronix pin compatibility and CFI is not required |
Compared with SST39VF800A-70-4I-M1QE, the -4C variant trades industrial temperature tolerance for lower cost, while MX29LV800CTTI-70G requires firmware-level redesign due to non-JEDEC command differences and missing CFI metadata.

FAQ
What is the maximum operating temperature range for SST39VF800A-70-4I-M1QE?
The SST39VF800A-70-4I-M1QE is rated for industrial temperature operation from –40°C to +85°C, validated per Microchip's DS25001A datasheet. This range ensures reliable performance in harsh environments such as factory floors, vehicle engine compartments, and outdoor networking equipment where thermal cycling occurs.
Does SST39VF800A-70-4I-M1QE support Common Flash Interface (CFI)?
Yes, SST39VF800A-70-4I-M1QE fully supports CFI mode. Writing 0x98 to address 0x5555 enters CFI Query mode, exposing standardized geometry and timing data at addresses 0x10–0x2F. This enables automatic driver initialization in Linux MTD and U-Boot environments without hard-coded parameters.
How many erase sectors does SST39VF800A-70-4I-M1QE have, and what is their size?
The SST39VF800A-70-4I-M1QE contains 256 uniform sectors, each 4 KB (2 KWords) in size, as confirmed by CFI Table 9 (00FFH sector count, 0010H sector size). This allows precise firmware patching-e.g., updating a single 4 KB bootloader section without erasing application code.
What is the guaranteed endurance specification for SST39VF800A-70-4I-M1QE?
SST39VF800A-70-4I-M1QE guarantees 100,000 program/erase cycles per sector, with data retention exceeding 100 years at +85°C. This endurance is achieved via SuperFlash split-gate technology and is tested per JEDEC JESD22-A117, making it suitable for devices requiring field firmware updates over a decade-long service life.
Is SST39VF800A-70-4I-M1QE pin-compatible with SST39LF800A-70-4I-M1QE?
No - SST39VF800A-70-4I-M1QE and SST39LF800A-70-4I-M1QE share identical pinout and command set but differ in supply voltage: VF version operates at 2.7–3.6 V, LF version requires 3.0–3.6 V. Substituting one for the other risks functional failure below 3.0 V or excessive current above 3.6 V.
