Product details
Overview
SST39VF800A-90-4I-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 industrial microcontroller boot loaders.
For engineers reviewing the SST39VF800A-90-4I-B3KE-T datasheet, SST39VF800A-90-4I-B3KE-T pinout, SST39VF800A-90-4I-B3KE-T application, or SST39VF800A-90-4I-B3KE-T equivalent, key selection criteria include its 2.7 V minimum VDD support, uniform 2 KWord sector erase, 32 KWord block erase, toggle-bit/data# polling write completion detection, and TSOP-48 package compatibility with legacy x16 memory sockets.
Technical Context
This device implements a JEDEC-compliant x16 asynchronous parallel interface with standard CE#, OE#, and WE# control signals. Its SuperFlash® architecture uses a split-gate cell with thick-oxide tunneling injector to decouple erase/program timing from cycle count-ensuring fixed 18 ms sector/block erase and 14 µs word-program times across its full endurance life.
It supports three software-controlled erase modes (sector, block, chip) via six-byte command sequences initiated at address 5555H, and includes both hardware (VDD power-up/down detection, noise/glitch immunity) and JEDEC-standard Software Data Protection (SDP) to prevent inadvertent writes during power transitions or system faults.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16), providing 1 MB of nonvolatile storage for firmware images or configuration tables |
| Read Access Time | 70 ns max - enables direct execution from flash (XIP) in systems with ≤14 MHz bus timing budgets |
| VDD Operating Range | 2.7–3.6 V - supports wide-input industrial power rails and battery-backed operation without external regulators |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years in deployed equipment |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications like calibration data archives |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) - allows fine-grained update management without full-chip erasure |

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-70-4C-B3KE | 70 ns read speed same; commercial temp range (0°C to +70°C); same 48-pin TSOP package | Lacks industrial temperature qualification; unsuitable for under-hood or outdoor deployments | Select when cost-sensitive consumer applications require identical functionality without extended temp support |
| MX29LV800CTTI-90G | 8 Mbit x16, 90 ns read, 3.0–3.6 V VDD, 48-pin TSOP; no 2.7 V support; different command set and CFI structure | Requires driver modification due to non-JEDEC-compatible unlock sequences and polling behavior | Choose only if existing design already uses Macronix toolchain and layout accommodates minor timing differences |
Compared with SST39VF800A-90-4I-B3KE-T, the SST39VF800A-70-4C-B3KE offers identical electrical and functional behavior but lacks industrial temperature validation, while MX29LV800CTTI-90G requires firmware adaptation for command execution and status checking-making the original part optimal for new industrial designs requiring guaranteed -40°C to +85°C operation and JEDEC interoperability.

FAQ
What is the maximum operating temperature range for the SST39VF800A-90-4I-B3KE-T?
The SST39VF800A-90-4I-B3KE-T is rated for industrial operation from -40°C to +85°C ambient temperature. This specification is validated per the device's DC and AC operating characteristics tables in the DS25001A datasheet and applies across its full 2.7–3.6 V VDD range. The "I" suffix in the part number explicitly denotes industrial temperature grade, distinguishing it from commercial-grade variants like SST39VF800A-70-4C-B3KE.
Does the SST39VF800A-90-4I-B3KE-T require an external VPP voltage for programming?
No, the SST39VF800A-90-4I-B3KE-T does not require an external VPP voltage. It generates all necessary high-voltage programming pulses internally using on-chip charge pumps powered solely by the 2.7–3.6 V VDD supply. This eliminates the need for auxiliary power supplies or level shifters, simplifying board design and reducing system cost compared to older flash technologies.
How many address lines are used by the SST39VF800A-90-4I-B3KE-T, and which ones are active for this density?
The SST39VF800A-90-4I-B3KE-T uses address lines A0 through A18 to access its 512K × 16 organization. For the 8 Mbit (SST39VF800A) variant, A16, A17, and A18 function as most-significant address bits and are required to select the full address space; A16–A18 are inactive (NC) in lower-density variants like SST39VF400A and SST39VF200A.
What erase modes does the SST39VF800A-90-4I-B3KE-T support, and what are their respective granularities?
The SST39VF800A-90-4I-B3KE-T supports three erase modes: sector-erase (2 KWord = 4 KB), block-erase (32 KWord = 64 KB), and chip-erase (entire 8 Mbit array). Sector and block erase times are both 18 ms typical; chip-erase takes 70 ms typical. All modes use JEDEC-standard six-byte command sequences initiated at address 5555H, with sector/block addresses loaded in the final cycle.
Is the SST39VF800A-90-4I-B3KE-T compatible with Common Flash Interface (CFI) readers and programmers?
Yes, the SST39VF800A-90-4I-B3KE-T fully supports the Common Flash Interface (CFI) specification. It responds to the CFI Query command (5555H/98H) with standardized geometry, timing, and command-set descriptors stored in on-die registers. This enables automatic identification and configuration by CFI-aware tools such as Segger Flasher, Linux mtd-utils, and commercial universal programmers without manual device definition.
