Product details
Overview
SST39VF800A-70-4C-EKE from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC with x16 asynchronous interface, 70 ns read access time, 2.7–3.6V single-supply operation, and JEDEC-standard pinout. It delivers high-reliability nonvolatile storage for firmware, boot code, and configuration data in embedded control systems.
For engineers reviewing the SST39VF800A-70-4C-EKE datasheet, SST39VF800A-70-4C-EKE pinout, SST39VF800A-70-4C-EKE application, or SST39VF800A-70-4C-EKE equivalent, this page provides verified specifications, TSOP-48 package layout, sector/block erase architecture, SuperFlash reliability metrics, and direct alternative part comparisons for industrial firmware storage design.
Technical Context
The SST39VF800A-70-4C-EKE implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed 14 µs word-program and 18 ms sector/block-erase times independent of endurance cycles. It supports JEDEC-standard command sets including Software Data Protection (SDP) and Common Flash Interface (CFI) query mode.
It operates in standard Read, Word-Program, Sector-Erase (2 KWord), Block-Erase (32 KWord), and Chip-Erase modes, with end-of-write detection via Toggle Bit (DQ6) and Data# Polling (DQ7). Hardware write protection includes VDD power-up/down detection and noise/glitch immunity on WE#/CE#.

Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, surface-mountable with standard reflow profile (260°C/10 s).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | A0–A17 used (A18 = AMS for 8 Mbit); selects byte/word location during read/write; A11–A17 define sector address in erase mode |
| DQ0–DQ15 | Data I/O | x16 bidirectional bus; latched internally during writes; tri-stated when CE# or OE# high |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-70-4I-EKE | Same 8 Mbit density, 70 ns access, and TSOP-48 package; rated for –40°C to +85°C industrial temperature range vs. 0°C to +70°C commercial grade | Required for outdoor or under-hood automotive/industrial deployments where extended temperature operation is mandatory | Select when ambient operating temperature exceeds 70°C or requires I-grade qualification |
| MX29LV800CTTI-70G | 8 Mbit x16 flash with 70 ns access, but uses different command set (non-JEDEC SDP), lacks CFI support, and has higher 25 mA active current | Compatible in pinout but requires firmware driver modification; not drop-in for CFI-aware bootloaders | Choose only if existing system already uses Macronix drivers and does not rely on CFI auto-detection |
Compared with SST39VF800A-70-4C-EKE, the -4I-EKE variant adds extended temperature capability without changing timing or interface, while MX29LV800CTTI-70G requires driver-level changes and offers no CFI interoperability-making SST39VF800A-70-4C-EKE optimal for new designs needing JEDEC compliance and long-term reliability.

FAQ
What is the maximum operating temperature range for SST39VF800A-70-4C-EKE?
The SST39VF800A-70-4C-EKE is specified for commercial temperature operation from 0°C to +70°C. Its 2.7–3.6V supply range and 100-year data retention make it suitable for indoor industrial and consumer electronics applications where ambient temperature remains within this band. For extended-range use, consider the SST39VF800A-70-4I-EKE variant.
Does SST39VF800A-70-4C-EKE support Common Flash Interface (CFI)?
Yes, SST39VF800A-70-4C-EKE fully supports CFI query mode via the standard three-byte entry sequence (0x5555/0xAA, 0x2AAA/0x55, 0x5555/0x98). The CFI table (addresses 0x10–0x34) reports geometry, timing, and command-set details, enabling automatic driver initialization in Linux MTD and U-Boot environments.
How many erase sectors does SST39VF800A-70-4C-EKE have, and what is their size?
The SST39VF800A-70-4C-EKE contains 256 uniform sectors, each sized at 2 KWords (4 KBytes). This structure allows precise firmware partitioning-for example, dedicating individual sectors to bootloader, kernel, rootfs, and application overlays-enabling atomic updates without full chip erase.
What write protection mechanisms does SST39VF800A-70-4C-EKE implement?
SST39VF800A-70-4C-EKE implements dual-layer protection: hardware features (VDD power-up/down detection, 5 ns input glitch immunity, and write-inhibit mode via OE#/CE#/WE# states) plus JEDEC-standard Software Data Protection requiring a three-byte unlock sequence before any program/erase command.
Is SST39VF800A-70-4C-EKE pin-compatible with SST39LF800A-70-4C-EKE?
Yes, SST39VF800A-70-4C-EKE and SST39LF800A-70-4C-EKE share identical TSOP-48 pinout, command set, and x16 interface. The key difference is supply voltage: SST39VF800A operates from 2.7–3.6V, while SST39LF800A requires 3.0–3.6V. System designers may substitute the VF version where lower-voltage operation is needed.
