Product details
Overview
SST39VF802C-70-4I-EKE-T from Microchip Technology is a 8 Mbit (512K × 16) CMOS Multi-Purpose Flash Plus memory IC with 70 ns read access time, single 2.7–3.6V supply operation, and top-boot block protection. It delivers 100,000 program/erase cycles, >100 years data retention, and supports sector/block/chip erase in embedded firmware storage applications.
For engineers reviewing the SST39VF802C-70-4I-EKE-T datasheet, SST39VF802C-70-4I-EKE-T pinout, SST39VF802C-70-4I-EKE-T application, or SST39VF802C-70-4I-EKE-T equivalent, this page provides verified technical context, JEDEC-compliant x16 interface details, boot-block protection mapping, SuperFlash® endurance metrics, and real-world design implications for firmware update systems.
Technical Context
The SST39VF802C-70-4I-EKE-T implements SST's proprietary SuperFlash® technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its JEDEC-standard x16 parallel interface includes dedicated WP#, RST#, and open-drain RY/BY# for hardware status signaling.
It supports three software-controlled erase granularities-uniform 2 KWord sectors, flexible blocks (one 8-, two 4-, one 16-, fifteen 32-KWord), and full-chip erase-and features Erase-Suspend/Resume for concurrent read/program during active erase. The device uses toggle-bit (DQ6/DQ2) and Data# Polling (DQ7) for end-of-write detection without external timing dependencies.
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 data. |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) in 5 MHz bus systems with no wait states. |
| Supply Voltage | 2.7–3.6V - compatible with 3.3V logic domains and tolerant of brown-out conditions down to 2.7V. |
| Endurance | 100,000 program/erase cycles - supports field firmware updates over 10+ years in industrial controllers. |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage for medical or aerospace black-box logging. |
| Block Protection | Top 8 KWord (7E000H–7FFFFH) hardware-protected via WP# - secures bootloader code against accidental overwrite. |
| Power Consumption | 5 mA active / 3 µA standby - reduces system-level power budget in battery-backed IoT gateways. |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, standard JEDEC x16 memory footprint.
| 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-stated when CE# or OE# high. |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 µA) when high, enabling multi-chip memory expansion. |
| OE# | Output Enable | Active-low output gate; controls data bus drive without affecting internal state or power mode. |
| WE# | Write Enable | Active-low write strobe; latches address/data on falling/rising edges per JEDEC command sequences. |
| WP# | Write Protect | Active-low hardware lock for top 8 KWord boot block; floating = internally pulled high (unprotected). |
| RST# | Reset | Active-low hardware reset; terminates ongoing erase/program and forces return to read mode within TRP. |
| RY/BY# | Ready/Busy# | Open-drain status indicator; requires external 10–100 kΩ pull-up; low = busy, high = ready for next command. |
| VDD / VSS | Power / Ground | Single 2.7–3.6V supply; dual VSS pins reduce noise coupling in high-speed read cycles. |
| NC | No Connect | Unbonded pins (e.g., A13, A9 in TSOP); must remain unconnected per datasheet layout guidance. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Split-gate cell architecture delivers fixed 18 ms sector/block erase and 7 µs word-program times across full lifecycle. |
| Erase-Suspend/Resume | Allows real-time read access to non-suspended sectors during active erase, enabling background firmware validation. |
| Hardware Block Protection | Top 8 KWord boot block (7E000H–7FFFFH) locked by WP# signal - prevents corruption of critical bootloader code. |
| Security ID Space | Factory-programmed 128-bit ID + 128-word user space, programmable via dedicated command sequence and lockable post-configuration. |
| CFI Compliance | Supports Common Flash Interface query mode (98H command) for automatic driver detection and runtime parameter extraction. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV800CTTI-70G | 8 Mbit (512K × 16), 70 ns, 3.0–3.6V supply; lacks RST# pin and Erase-Suspend feature. | Requires external reset management; unsuitable for systems needing in-erase read capability. | Select when cost sensitivity outweighs need for suspend/resume and hardware reset integration. |
| S29GL064N90TFIR20 | 64 Mbit (4M × 16), 90 ns, 2.7–3.6V; includes CFI but no Security ID; different block architecture (64 KWord uniform sectors). | Higher density but slower access; incompatible boot-block layout and erase granularity for SST39VF802C-70-4I-EKE-T migration. | Choose only for new designs requiring >8 Mbit capacity and where 90 ns latency is acceptable. |
Compared with MX29LV800CTTI-70G and S29GL064N90TFIR20, the SST39VF802C-70-4I-EKE-T uniquely combines top-boot hardware protection, Erase-Suspend, and integrated RST# in an 8 Mbit x16 package - making it optimal for safety-critical firmware storage where bootloader integrity and real-time operational flexibility are mandatory.

FAQ
What is the boot block configuration of the SST39VF802C-70-4I-EKE-T?
The SST39VF802C-70-4I-EKE-T implements top-boot block protection covering the 8 KWord address range 7E000H–7FFFFH. This region is hardware-locked when WP# is driven low, safeguarding bootloader code from accidental erase or program operations. Unlike the SST39VF801C variant, the SST39VF802C-70-4I-EKE-T does not protect the bottom block.
Does the SST39VF802C-70-4I-EKE-T require an external VPP voltage?
No, the SST39VF802C-70-4I-EKE-T does not require an external VPP voltage. It generates all necessary high-voltage programming pulses internally using its 2.7–3.6V VDD supply. This eliminates the need for auxiliary power rails and simplifies PCB design compared to older flash technologies.
How is end-of-write detection implemented in the SST39VF802C-70-4I-EKE-T?
The SST39VF802C-70-4I-EKE-T supports three end-of-write detection methods: Toggle Bit (DQ6 toggles during operation, stops when complete), Data# Polling (DQ7 complements data during program, returns true value on completion), and Ready/Busy# (RY/BY# open-drain pin pulled low during operation). All are usable concurrently and require no external timing components.
Can the SST39VF802C-70-4I-EKE-T be used in place of the SST39VF801C?
No - the SST39VF802C-70-4I-EKE-T and SST39VF801C are not functionally interchangeable due to opposite boot block configurations: SST39VF802C-70-4I-EKE-T protects the top 8 KWord (7E000H–7FFFFH), while SST39VF801C protects the bottom 8 KWord (00000H–01FFFH). Software and hardware protection schemes must be redesigned for substitution.
What package type is used in the SST39VF802C-70-4I-EKE-T part number suffix?
The "EKE" suffix in SST39VF802C-70-4I-EKE-T denotes the 48-lead TSOP (Thin Small Outline Package) with 12 mm × 20 mm body size and standard JEDEC pinout. This package is lead-free (RoHS-compliant) and rated for industrial temperature range (–40°C to +85°C), indicated by the "I" in the suffix.
