Product details
Overview
SST39VF801C-70-4C-EKE 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 from 2.7–3.6V, delivers 70 ns read access time, supports sector/block/chip erase, and features hardware write protection via WP# pin for bottom 8 KWord boot block (00000H–01FFFH).
For engineers reviewing the SST39VF801C-70-4C-EKE datasheet, SST39VF801C-70-4C-EKE pinout, SST39VF801C-70-4C-EKE application, or SST39VF801C-70-4C-EKE equivalent, this device serves as a JEDEC-standard x16 flash solution requiring fast Word-Program (7 µs typ.), high endurance (100,000 cycles), and reliable data retention (>100 years) in industrial control, firmware update, and BIOS storage designs.
Technical Context
The SST39VF801C-70-4C-EKE implements a split-gate SuperFlash® cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count-unlike conventional flash technologies. Its command interface follows JEDEC-standard x16 pinouts and uses six-byte sequences for sector/block/chip erase, with software data protection permanently enabled at shipment.
It integrates dual status detection (DQ6 toggle bit and DQ7 Data# polling), an open-drain RY/BY# pin for hardware busy indication, and hardware reset (RST#) for forced return to read mode. The device supports Auto Low Power mode (3 µA standby current) and latched address/data I/O compatible with standard microprocessor buses.
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 masking |
| Read Access Time | 70 ns max - enables direct connection to 14 MHz microcontrollers without wait states |
| Supply Voltage | 2.7–3.6V - supports single-supply operation in battery-backed or low-voltage industrial systems |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years of service life |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications like configuration EEPROM replacement |
| Word-Program Time | 7 µs typical - reduces firmware update latency versus legacy parallel flash devices |
| Standby Current | 3 µA typical - critical for low-power modes in portable or energy-harvesting embedded systems |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, JEDEC-standard x16 memory footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus; A18 is most significant; AMS = A18 for sector/block selection |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with tri-state output controlled by CE# and OE# |
| CE# | Chip Enable | Active-low chip select; device enters standby when high, enabling multi-chip memory expansion |
| OE# | Output Enable | Active-low output gate; controls data bus drive without affecting internal state |
| WE# | Write Enable | Active-low control for all write operations; latches command/address/data on falling/rising edges per JEDEC timing |
| WP# | Write Protect | Hardware lock for bottom 8 KWord boot block (00000H–01FFFH); grounded = protection enabled |
| RST# | Reset | Active-low hardware reset; terminates ongoing erase/program and forces return to read mode |
| RY/BY# | Ready/Busy# | Open-drain status indicator; pulled low during erase/program, requires external 10–100 kΩ pull-up |
| VDD | Power Supply | 2.7–3.6V core supply; powers all logic and memory array functions |
| VSS | Ground | Reference ground for all I/O and internal circuitry; two dedicated pins for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell with thick-oxide injector enables fixed 7 µs program and 18 ms erase times across full lifecycle |
| Erase-Suspend/Resume | Allows temporary halt of sector/block erase to read other locations or program unprotected blocks |
| Security ID Space | 128-bit factory-programmed ID + 128-word user-programmable space, locked after programming |
| Boot Block Protection | Hardware-enforced bottom 8 KWord (00000H–01FFFH) protection via WP# pin - matches BIOS/UEFI storage requirements |
| CFI Support | Common Flash Interface compliant; enables automatic driver detection and configuration in host OS/bootloader |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF802C-70-4C-EKE | Top-boot architecture (7E000H–7FFFFH protected block); identical timing, voltage, and command set | Used where boot code resides in top memory region; not interchangeable without PCB address mapping change | Select only if system design requires top-boot protection and address map aligns |
| MX29LV800CTTI-70G | 70 ns access, 3.0–3.6V operation, but lacks Erase-Suspend and Security ID; different command sequence and CFI layout | Lower-cost alternative for basic firmware storage without advanced protection or suspend features | Choose when Erase-Suspend, Security ID, or bottom-boot protection are not required |
Compared with SST39VF801C-70-4C-EKE, the SST39VF802C-70-4C-EKE offers identical performance but reversed boot-block location, while MX29LV800CTTI-70G sacrifices advanced features for cost-making SST39VF801C-70-4C-EKE optimal for secure, field-upgradable embedded systems demanding bottom-boot integrity.

FAQ
What is the boot block configuration of SST39VF801C-70-4C-EKE?
The SST39VF801C-70-4C-EKE implements bottom-boot block protection: the lowest 8 KWord (00000H–01FFFH) is hardware-protected when WP# is grounded. This matches BIOS/UEFI and safety-critical startup code placement requirements. Unlike the SST39VF802C variant, it does not protect the top memory region.
Does SST39VF801C-70-4C-EKE require an external VPP voltage for programming?
No, SST39VF801C-70-4C-EKE does not require external VPP. It generates internal high-voltage programming pulses using its on-chip charge pump, enabling full erase and program functionality from a single 2.7–3.6V supply-simplifying power design and eliminating VPP routing on PCB.
How is write completion detected on SST39VF801C-70-4C-EKE?
SST39VF801C-70-4C-EKE supports three concurrent write completion detection methods: DQ6 toggle bit (alternating 1/0 during operation), DQ7 Data# polling (complement-to-data during program, 0 during erase), and RY/BY# pin (open-drain active-low signal). All are valid after defined WE# edge timings per operation type.
Can SST39VF801C-70-4C-EKE be used in place of SST39VF802C-70-4C-EKE?
No-SST39VF801C-70-4C-EKE and SST39VF802C-70-4C-EKE are not interchangeable due to opposite boot block architectures: SST39VF801C protects the bottom 8 KWord, while SST39VF802C protects the top 8 KWord. Swapping them risks corrupting protected firmware unless address mapping and protection logic are redesigned.
What package options are available for SST39VF801C-70-4C-EKE?
The SST39VF801C-70-4C-EKE is offered exclusively in 48-lead TSOP (12 mm × 20 mm) per the DS25041A datasheet. While the broader SST39VF801C family includes TFBGA and WFBGA variants, the -EKE suffix specifically denotes the TSOP package with commercial temperature range (0°C to +70°C) and 70 ns speed grade.
