Product details
Overview
SST39VF800A-70-4I-EKE-T from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC with x16 asynchronous interface, 70 ns read access time, 2.7–3.6 V single-supply operation, and JEDEC-standard pinout. It delivers uniform 2 KWord sector and 32 KWord block erase, 14 µs word-program time, and >100 years data retention for embedded firmware storage in industrial controllers.
For engineers reviewing the SST39VF800A-70-4I-EKE-T datasheet, SST39VF800A-70-4I-EKE-T pinout, SST39VF800A-70-4I-EKE-T application, or SST39VF800A-70-4I-EKE-T equivalent, this page provides verified package mapping (48-ball TFBGA), SuperFlash technology advantages, hardware/software data protection, CFI support, and real-world timing behavior for system integration.
Technical Context
The SST39VF800A-70-4I-EKE-T implements SST's proprietary SuperFlash split-gate cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its command-set follows JEDEC standard x16 flash protocols, including six-byte software data protection sequences for sector/block/chip erase and word-program operations.
It supports three end-of-write detection methods-Data# Polling (DQ7), Toggle Bit (DQ6), and CFI Query-and operates across -40°C to +85°C with 2.7–3.6 V supply. The device uses latched address/data inputs and tri-state outputs controlled by CE#, OE#, and WE# signals, conforming to standard microprocessor bus timing.
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-EKE-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 environments; unsuitable for outdoor or under-hood automotive use | Select only for cost-sensitive consumer-grade applications with controlled ambient conditions |
| MX29LV800CTTI-70G | Same density and 70 ns speed, but uses different command set (non-JEDEC-compatible); requires firmware driver modification | Lacks CFI query support and has slower chip-erase (100 ms vs. 70 ms typical) | Use only when existing design already supports Macronix command protocol and thermal requirements align |
Compared with SST39VF800A-70-4I-EKE-T, the -4C variant trades industrial temperature tolerance for lower cost, while MX29LV800CTTI-70G requires driver-level changes and offers no CFI runtime identification - making SST39VF800A-70-4I-EKE-T preferable for new designs requiring field-upgradability and broad environmental resilience.

The SST39VF800A-70-4I-EKE-T is organized as 512K words × 16 bits, totaling 8 Mbit (1,048,576 bytes). This structure supports byte-wide or word-wide access depending on system bus configuration, and maps directly to standard 16-bit microprocessor data buses without external data-width conversion logic.
Does the SST39VF800A-70-4I-EKE-T require an external VPP voltage for programming?
No, the SST39VF800A-70-4I-EKE-T does not require an external VPP voltage. It generates all necessary high-voltage programming pulses internally using its on-chip charge pump, enabling single 2.7–3.6 V supply operation for both read and write functions - a key advantage over older flash technologies.
How many erase sectors and blocks does the SST39VF800A-70-4I-EKE-T support?
The SST39VF800A-70-4I-EKE-T supports 256 uniform sectors of 2 KWords (4 KB) each and 16 uniform blocks of 32 KWords (64 KB) each. This hierarchical erase architecture allows fine-grained updates (e.g., parameter tables) or bulk reprogramming (e.g., full firmware images) without compromising data integrity in adjacent regions.
Is the SST39VF800A-70-4I-EKE-T compatible with JEDEC-standard x16 flash controllers?
Yes, the SST39VF800A-70-4I-EKE-T conforms fully to JEDEC standard pinouts and command sets for x16 parallel flash memory. It supports standard read, word-program, sector-erase, block-erase, and chip-erase commands, and is interoperable with existing JEDEC-compliant flash controllers and bootloader firmware.
What package type is used for the SST39VF800A-70-4I-EKE-T?
The SST39VF800A-70-4I-EKE-T uses a 48-ball Thin Fine-Pitch Ball Grid Array (TFBGA) package measuring 6 mm × 8 mm. This RoHS-compliant, lead-free package supports automated SMT assembly and provides superior thermal and electrical performance compared to TSOP alternatives, especially in high-density PCB layouts.
