Product details
Overview
SST39VF800A-70-4I-B3KE-T from Microchip Technology is an 8 Mbit (512K x 16) CMOS Multi-Purpose Flash memory IC using SuperFlash technology, operating at 2.7–3.6V with 70 ns read access time, 14 µs word-program time, and JEDEC-standard x16 asynchronous interface. It delivers 100,000 program/erase cycles and >100 years data retention for embedded firmware storage in industrial controllers.
For engineers reviewing the SST39VF800A-70-4I-B3KE-T datasheet, SST39VF800A-70-4I-B3KE-T pinout, SST39VF800A-70-4I-B3KE-T application, or SST39VF800A-70-4I-B3KE-T equivalent, this page provides verified pin functions, sector/block erase timing, SuperFlash reliability metrics, JEDEC-compliant command set, and industrial-grade temperature support (–40°C to +85°C).
Technical Context
The SST39VF800A-70-4I-B3KE-T implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It supports uniform 2 KWord sectors (256 total) and 32 KWord blocks (16 total), with hardware/software data protection including noise/glitch immunity and VDD power-up/down detection.
Command execution follows JEDEC-standard sequences: three-byte load for Word-Program, six-byte for Sector/Block/Chip-Erase, and CFI Query entry via 5555H/AAH/2AAAH/55H/5555H/98H. End-of-write detection uses DQ7 Data# Polling and DQ6 Toggle Bit, both valid after the rising edge of the fourth (Program) or sixth (Erase) WE# pulse.
Key Specifications

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-B3KE-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 thermal cycling or cold-start automotive/industrial environments | Select for cost-sensitive consumer electronics where ambient temperature remains controlled |
| MX29LV800CTTI-70G | 8 Mbit x16, 70 ns access, but uses different command set (non-JEDEC standard) and lacks CFI support | Requires custom driver adaptation; no automatic geometry detection | Choose only when existing firmware already supports Macronix command protocol and CFI is unused |
Compared with SST39VF800A-70-4I-B3KE-T, the -4C variant trades industrial temperature qualification for lower unit cost in benign environments, while MX29LV800CTTI-70G requires firmware rework due to incompatible command architecture and absence of CFI metadata.

FAQ
What is the maximum operating temperature range for the SST39VF800A-70-4I-B3KE-T?
The SST39VF800A-70-4I-B3KE-T is rated for industrial temperature operation from –40°C to +85°C, as specified in the DS25001A datasheet Table 9. This range is validated for continuous operation under bias and ensures reliable performance in harsh environments such as factory automation and outdoor networking equipment. The 'I' suffix in the part number explicitly denotes industrial grade, distinguishing it from commercial-grade variants like SST39VF800A-70-4C-B3KE-T.
Does the SST39VF800A-70-4I-B3KE-T require an external VPP voltage for programming?
No, the SST39VF800A-70-4I-B3KE-T does not require an external VPP voltage. It features internal VPP generation powered solely by the 2.7–3.6V VDD supply, eliminating the need for high-voltage circuitry on the host board. This simplifies system design and reduces bill-of-materials cost. All program and erase operations-including Word-Program, Sector-Erase, Block-Erase, and Chip-Erase-are executed using only the main VDD rail, as confirmed in the DS25001A datasheet Features section and Device Operation chapter.
How many sectors and blocks does the SST39VF800A-70-4I-B3KE-T support, and what are their sizes?
The SST39VF800A-70-4I-B3KE-T supports 256 uniform sectors of 2 KWord (4 KByte) each and 16 uniform blocks of 32 KWord (64 KByte) each, as defined in Table 9 (Device Geometry Information for SST39LF/VF800A) of the DS25001A datasheet. This structure enables flexible memory management-small sectors allow fine-grained updates (e.g., calibration tables), while large blocks optimize full-image rewrites (e.g., firmware upgrades). Sector and block addresses are selected using AMS–A11 and AMS–A15 lines respectively.
Is the SST39VF800A-70-4I-B3KE-T pin-compatible with other devices in the SST39VF family?
Yes, the SST39VF800A-70-4I-B3KE-T shares identical pinout and command set with SST39VF200A and SST39VF400A in the same package variant (e.g., 48-ball TFBGA), per JEDEC-standard x16 flash pin assignments documented in Figures 2–4 of DS25001A. However, address line mapping differs: SST39VF800A uses A18 as the most significant address (AMS), whereas SST39VF200A uses A16 and SST39VF400A uses A17. System firmware must account for this address width difference to avoid misreads.
What end-of-write detection methods does the SST39VF800A-70-4I-B3KE-T support?
The SST39VF800A-70-4I-B3KE-T supports two hardware-supported end-of-write detection methods: Data# Polling (DQ7) and Toggle Bit (DQ6). During Program, DQ7 returns complemented data until completion, then true data; during Erase, DQ7 transitions from '0' to '1'. DQ6 toggles between 0 and 1 during internal operations and stops upon completion. Both methods are valid after the rising edge of the fourth WE# pulse (Program) or sixth WE# pulse (Erase), enabling efficient polling without timer dependencies.
