Product details
Overview
SST39VF800A-70-4C-B3KE-T from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC with 2.7–3.6 V single-supply operation, 70 ns read access time, JEDEC-standard x16 asynchronous interface, and SuperFlash® split-gate technology enabling 100,000 program/erase cycles and >100 years data retention. It serves as nonvolatile code/data storage in embedded microcontroller systems requiring field-upgradable firmware.
For engineers reviewing the SST39VF800A-70-4C-B3KE-T datasheet, SST39VF800A-70-4C-B3KE-T pinout, SST39VF800A-70-4C-B3KE-T application, or SST39VF800A-70-4C-B3KE-T equivalent, key selection criteria include its 48-pin TSOP package, sector/block-erase architecture (2 KWord sectors / 32 KWord blocks), toggle-bit/data# polling status detection, hardware/software write protection, and CFI-compliant device identification.
Technical Context
The SST39VF800A-70-4C-B3KE-T implements a JEDEC-standard x16 asynchronous parallel interface with dedicated CE#, OE#, and WE# control lines. Its SuperFlash® technology uses a split-gate cell with thick-oxide tunneling injector to deliver fixed erase/program timing independent of wear level.
It supports three erase modes-sector (2 KWord), block (32 KWord), and chip-wide-with uniform timing (18 ms typical for sector/block, 70 ms for chip). Word-program time is 14 µs typical, and it provides both Data# Polling (DQ7) and Toggle Bit (DQ6) for end-of-write detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-70-4I-B3KE-T | Industrial temperature grade (-40°C to +85°C); identical electrical specs and pinout | Required for extended-temperature deployments where commercial-grade (0°C to +70°C) is insufficient | Select when ambient operating conditions exceed 70°C or drop below 0°C |
| MX29LV800CTTI-70G | Same density (8 Mbit x16), 70 ns access, but uses different command set and lacks CFI query; 3.0–3.6 V only | Not drop-in replaceable due to incompatible software protection and erase command sequences | Choose only if existing firmware already supports Macronix command protocol and voltage range matches |
Compared with SST39VF800A-70-4C-B3KE-T, the -4I variant adds extended temperature support without layout changes, while MX29LV800CTTI-70G requires firmware modification for command compatibility and operates in a narrower voltage window.

FAQ
What is the maximum operating temperature range for the SST39VF800A-70-4C-B3KE-T?
The SST39VF800A-70-4C-B3KE-T is rated for commercial temperature operation from 0°C to +70°C. It is not qualified for industrial temperatures; for -40°C to +85°C operation, the SST39VF800A-70-4I-B3KE-T variant must be used. Both share identical electrical specifications, pinout, and timing, differing only in temperature screening and test conditions.
Does the SST39VF800A-70-4C-B3KE-T require an external VPP voltage for programming?
No, the SST39VF800A-70-4C-B3KE-T does not require an external VPP voltage. It integrates an internal charge pump that generates the necessary high voltage for program and erase operations from the single 2.7–3.6 V VDD supply. This eliminates the need for auxiliary power circuitry and simplifies system design compared to older flash technologies.
How many erase sectors does the SST39VF800A-70-4C-B3KE-T contain?
The SST39VF800A-70-4C-B3KE-T contains 256 uniform 2 KWord sectors (4 KB each), totaling 1 MB of addressable space. This sector count is confirmed in Table 9 of the DS25001A datasheet, where Device Geometry Information shows y = 255 → 256 sectors. Each sector can be erased independently without affecting others.
Is the SST39VF800A-70-4C-B3KE-T pin-compatible with the SST39LF800A series?
Yes, the SST39VF800A-70-4C-B3KE-T is pin-compatible with the SST39LF800A series in the same package (e.g., 48-pin TSOP), sharing identical pin assignments and JEDEC-standard x16 interface. However, voltage ranges differ: SST39LF800A requires 3.0–3.6 V, while SST39VF800A operates from 2.7–3.6 V - direct substitution is electrically valid only if system VDD remains ≥3.0 V.
What command sequence initiates Chip-Erase on the SST39VF800A-70-4C-B3KE-T?
The Chip-Erase command for SST39VF800A-70-4C-B3KE-T is a six-byte sequence: write 0xAA to address 0x5555, 0x55 to address 0x2AAA, 0x80 to address 0x5555, then 0xAA to 0x5555, 0x55 to 0x2AAA, and finally 0x10 to address 0x5555. This sequence is defined in Table 4 of DS25001A and triggers full-array erase in 70 ms typical.
