Product details
Overview
SST39VF800A-70-4I-B3KE-T-MCH from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC using SuperFlash technology, operating at 2.7–3.6 V with 70 ns read access time, 14 µs word-program time, and JEDEC-standard x16 asynchronous interface. It serves as nonvolatile program/data storage in embedded controllers, industrial HMIs, and legacy BIOS modules.
For engineers reviewing the SST39VF800A-70-4I-B3KE-T-MCH datasheet, SST39VF800A-70-4I-B3KE-T-MCH pinout, SST39VF800A-70-4I-B3KE-T-MCH application, or SST39VF800A-70-4I-B3KE-T-MCH equivalent, key selection criteria include its 2.7 V minimum VDD support, uniform 2 KWord sector/32 KWord block erase architecture, toggle-bit/data# polling write status detection, and TSOP-48 package compatibility with legacy x16 memory sockets.
Technical Context
This device implements a split-gate SuperFlash cell with thick-oxide tunneling injector for enhanced endurance and data retention. Its command-set architecture follows JEDEC-standard flash protocols, requiring six-byte sequences for sector/block/chip erase and three-byte sequences for word-program initiation.
It supports hardware write inhibit via CE#/OE#/WE# logic states and software data protection (SDP) with permanent enablement at shipment. The device provides CFI query mode for runtime identification and supports both Software Product ID and Common Flash Interface standards for system-level interoperability.

IC Role / Device Role / Timing Role: Background log buffer updated asynchronously via interrupt-driven writes; read during technician interrogation. Use Value: 3 µA standby current extends battery backup life; block-erase mode enables rapid log rotation without full-chip erase delays. |
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 | Commercial temperature grade (0°C to +70°C); identical electrical specs and pinout | Limited to climate-controlled environments; not rated for extended industrial thermal cycling | Select when cost sensitivity outweighs environmental qualification requirements |
| MX29LV800CTTI-70G | Same density, 70 ns access, but uses different command set and lacks CFI support; requires firmware adaptation | Requires modified driver layer for erase/write commands; no runtime geometry discovery | Choose only if existing design already uses Macronix-compatible firmware stack |
Compared with SST39VF800A-70-4I-B3KE-T-MCH, the commercial-grade SST39VF800A-70-4C-B3KE reduces thermal qualification cost but sacrifices operational margin, while MX29LV800CTTI-70G introduces firmware porting effort despite matching speed and density.

FAQ
What is the exact memory organization of the SST39VF800A-70-4I-B3KE-T-MCH?
The SST39VF800A-70-4I-B3KE-T-MCH is organized as 512K words × 16 bits (8 Mbit total), with address lines A0–A17 active and A18 serving as the most significant address (AMS) for sector/block selection. This configuration maps directly to a 1 MB linear address space accessible via standard x16 parallel bus interfaces.
Does the SST39VF800A-70-4I-B3KE-T-MCH require an external VPP voltage for programming?
No, the SST39VF800A-70-4I-B3KE-T-MCH does not require an external VPP voltage. It generates all necessary high-voltage programming signals internally using its on-chip charge pump, operating fully from the 2.7–3.6 V VDD supply. This eliminates external high-voltage circuitry and simplifies board design.
How is write completion detected on the SST39VF800A-70-4I-B3KE-T-MCH?
Write completion on the SST39VF800A-70-4I-B3KE-T-MCH is detected using two software methods: Data# Polling (DQ7 toggles to true data upon completion) and Toggle Bit (DQ6 alternates between 0 and 1 during operation and stops toggling when complete). Both are valid after the rising edge of the fourth WE# pulse for programming.
What package type is used in the SST39VF800A-70-4I-B3KE-T-MCH part number?
The SST39VF800A-70-4I-B3KE-T-MCH uses a 48-lead TSOP (Thin Small Outline Package) measuring 12 mm × 20 mm, with standard pinout compliant with JEDEC MO-142AC. This package is optimized for surface-mount assembly and backward compatibility with legacy x16 memory sockets.
Is the SST39VF800A-70-4I-B3KE-T-MCH compatible with CFI-based auto-configuration systems?
Yes, the SST39VF800A-70-4I-B3KE-T-MCH supports Common Flash Interface (CFI) mode. By issuing the 3-byte CFI Query command (5555H/AAH → 2AAAH/55H → 5555H/98H), the host can read standardized geometry, timing, and command-set descriptors from fixed CFI address locations (e.g., 10H–12H for "QRY" string).
