Product details
Overview
SST39VF801C-70-4I-B3KE-T from Microchip Technology is a 8 Mbit (512K × 16) CMOS Multi-Purpose Flash Plus memory IC with SuperFlash® technology, designed for embedded program/data storage in microcontroller-based systems. It operates at 2.7–3.6 V, delivers 70 ns read access time, supports hardware block protection on the bottom 8 KWord boot sector (00000H–01FFFH), and features sector/block/chip erase with erase-suspend/resume capability.
For engineers reviewing the SST39VF801C-70-4I-B3KE-T datasheet, SST39VF801C-70-4I-B3KE-T pinout, SST39VF801C-70-4I-B3KE-T application, or SST39VF801C-70-4I-B3KE-T equivalent, this device is selected for cost-sensitive, low-power industrial control firmware storage where fast word-program (7 µs typ.), JEDEC-compliant x16 interface, and 100,000-cycle endurance are required.
Technical Context
The SST39VF801C-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 and eliminating performance de-rating over lifetime. Its command-set follows JEDEC-standard flash protocols, including six-byte sequences for sector/block/chip erase and three-byte sequences for word-program and security ID operations.
It integrates dual status detection-Data# Polling (DQ7) and Toggle Bits (DQ6/DQ2)-plus open-drain RY/BY# output for real-time operation monitoring. Hardware protection is implemented via WP# pin controlling bottom-boot-block lock, while RST# provides hardware reset to Read mode with guaranteed recovery timing (TRHR).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16 organization), directly maps to 16-bit data bus without byte-lane multiplexing |
| Read Access Time | 70 ns max - enables direct connection to 14 MHz bus without wait states in most 16-bit microcontrollers |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V systems and tolerant of brown-out conditions down to 2.7 V |
| Endurance | 100,000 program/erase cycles - supports field firmware updates across product lifecycle |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications |
| Word-Program Time | 7 µs typical - reduces firmware update latency and improves system responsiveness during reprogramming |
| Active Current | 5 mA typical at 5 MHz - enables low-power operation in battery-backed or energy-constrained designs |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 512K-word addressing; AMS = A18 for sector/block selection |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with internal latching; tri-state when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select - device enters standby (3 µA) when high |
| OE# | Output Enable | Active-low output gate - controls data bus visibility without affecting internal state |
| WE# | Write Enable | Active-low write strobe - latches address/data on falling/rising edges per JEDEC timing |
| WP# | Write Protect | Active-low hardware lock for bottom 8 KWord boot block (00000H–01FFFH) |
| RST# | Reset | Active-low hardware reset - forces immediate return to Read mode, aborting pending operations |
| RY/BY# | Ready/Busy# | Open-drain status indicator - requires external 10–100 kΩ pull-up; low = active erase/program |
| VDD | Power Supply | 2.7–3.6 V supply - powers all internal logic and charge pumps; no external VPP required |
| VSS | Ground | Reference ground for all I/O and core circuitry |
| NC | No Connection | Unbonded pins - must be left floating or tied to VSS per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell with thick-oxide injector enables fixed 7 µs program / 18 ms erase times across full 100k-cycle life |
| Erase-Suspend/Resume | Allows interrupting sector/block erase to read or program other non-suspended sectors - critical for real-time firmware patching |
| Bottom Boot Block Protection | Hardware lock on lowest 8 KWord (00000H–01FFFH) prevents accidental overwrite of bootloader code |
| Security ID Space | Factory-programmed 128-bit ID + 128-word user-programmable space - supports device authentication and traceability |
| Auto Low Power Mode | Reduces active read current from 5 mA to 3 µA after valid access - cuts power in burst-read applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF802C-70-4I-B3KE-T | Top-boot architecture (protects 7E000H–7FFFFH); identical timing, voltage, and command set | Used where bootloader resides in top memory region instead of bottom; not interchangeable without firmware address remapping | Select only if system design allocates boot code to upper 8 KWord - pinout and interface are identical but protection zone differs |
| MX29LV800CTTC-70G | 8 Mbit x16 CFI-compliant flash; 70 ns access, 3.0–3.6 V supply; lacks erase-suspend and security ID | Lower-cost alternative for basic firmware storage without real-time suspend capability or device authentication | Choose when erase-suspend and security ID are unnecessary; verify JEDEC command compatibility - not drop-in due to differing status bit behavior |
Compared with SST39VF801C-70-4I-B3KE-T, the SST39VF802C variant shifts hardware protection to the top boot block, requiring firmware address alignment changes, while the MX29LV800CTTC offers baseline functionality at lower cost but omits critical features like erase-suspend and secure ID - making it unsuitable for safety-critical or field-upgradable systems.

FAQ
What is the boot block configuration of the SST39VF801C-70-4I-B3KE-T?
The SST39VF801C-70-4I-B3KE-T implements bottom-boot block protection, covering the lowest 8 KWord address range (00000H–01FFFH). This hardware-protected region is locked when WP# is grounded, preventing accidental erase or program of bootloader code. The protection is distinct from the SST39VF802C variant, which protects the top 8 KWord (7E000H–7FFFFH).
Does the SST39VF801C-70-4I-B3KE-T require an external VPP voltage for programming?
No, the SST39VF801C-70-4I-B3KE-T does not require an external VPP voltage. It uses internal charge pump circuitry to generate all necessary high voltages for erase and program operations from the single 2.7–3.6 V VDD supply. This simplifies power design and eliminates need for auxiliary voltage rails or external pump components.
How is write completion detected on the SST39VF801C-70-4I-B3KE-T?
Write completion on the SST39VF801C-70-4I-B3KE-T is detected using three complementary methods: Data# Polling (DQ7 toggles until operation completes), Toggle Bits (DQ6 toggles during erase/program), and Ready/Busy# (RY/BY# pin goes high when ready). All methods are valid after defined WE# edge timing and support robust host polling without timeout dependencies.
What package type is used for the SST39VF801C-70-4I-B3KE-T?
The SST39VF801C-70-4I-B3KE-T is packaged in a 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), designated by the "B3KE" suffix. This ultra-compact, RoHS-compliant package supports high-density PCB layouts and thermal performance suitable for industrial temperature operation (–40°C to +85°C).
Can the SST39VF801C-70-4I-B3KE-T be used in systems requiring secure device identification?
Yes, the SST39VF801C-70-4I-B3KE-T includes a dedicated Security ID space: 128 bits factory-programmed by SST and 128 words (256 bytes) user-programmable. The user segment can be permanently locked after programming, enabling device authentication, anti-counterfeiting, and secure key binding - all implemented in hardware without external crypto co-processors.
