Product details
Overview
SST39VF802C-70-4C-EKE from Microchip Technology is a 8 Mbit (512K × 16) 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 hardware block protection on the top 8 KWord boot sector, and features sector/block/chip erase with erase-suspend/resume capability.
For engineers reviewing the SST39VF802C-70-4C-EKE datasheet, SST39VF802C-70-4C-EKE pinout, SST39VF802C-70-4C-EKE application, or SST39VF802C-70-4C-EKE equivalent, this page provides verified technical context, JEDEC-compliant x16 interface details, boot-block protection mapping, SuperFlash endurance/reliability data, and real-world use cases in firmware-updatable industrial controllers and legacy BIOS modules.
Technical Context
This device implements a split-gate SuperFlash® cell architecture with thick-oxide tunneling injector, enabling fixed 7 µs word-program and 18 ms sector/block-erase times independent of cycle count. It uses standard JEDEC x16 flash command sets and supports CFI Query mode for automatic configuration detection.
Hardware protection is implemented via dedicated WP# pin controlling top-boot block (7E000H–7FFFFH), while RY/BY# provides open-drain ready/busy status signaling. The device integrates latched address/data paths, auto low-power mode (3 µA standby), and dual status detection (DQ6 toggle + DQ7 polling) for robust write-cycle management.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV800CTTC-70G | 70 ns access, same 8 Mbit x16 density, but uses conventional floating-gate architecture; no erase-suspend; 100K cycles rated at 3.0–3.6V only | Lacks top-boot hardware protection and CFI Query mode; requires software-managed block locking | Choose when cost sensitivity outweighs need for suspend/resume or factory ID security |
| EN29LV800AB-70TP | 70 ns access, 8 Mbit x16, supports top-boot protection and CFI, but endurance limited to 10K cycles; no Security ID feature | Compatible pinout and command set, but lower reliability limits field update frequency | Prefer for short-lifecycle consumer products where firmware rarely changes post-deployment |
Compared with MX29LV800CTTC-70G and EN29LV800AB-70TP, SST39VF802C-70-4C-EKE delivers superior long-term reliability (100K vs. 10K–100K cycles), integrated hardware boot protection, and factory/user Security ID - making it optimal for medical, industrial, and telecom applications requiring secure, field-upgradable firmware with multi-decade data integrity.

FAQ
What is the boot block configuration of SST39VF802C-70-4C-EKE?
The SST39VF802C-70-4C-EKE implements top-boot block protection covering address range 7E000H–7FFFFH (8 KWord). This is hardwired behavior confirmed in Table 4 and Section 10 of DS25041A. When WP# is grounded, program/erase operations are blocked in this region - protecting bootloader code from accidental overwrite. The SST39VF802C-70-4C-EKE does not support bottom-boot configuration; that variant is SST39VF801C.
Does SST39VF802C-70-4C-EKE require an external VPP voltage?
No, SST39VF802C-70-4C-EKE integrates internal VPP generation and operates solely from a single 2.7–3.6V VDD supply. This eliminates the need for external high-voltage circuitry, simplifying board design and reducing BOM cost. All program and erase functions - including Word-Program, Sector-Erase, Block-Erase, and Chip-Erase - execute using only the main VDD rail. The SST39VF802C-70-4C-EKE datasheet explicitly states "Internal VPP Generation" under Features.
How is write completion detected on SST39VF802C-70-4C-EKE?
The SST39VF802C-70-4C-EKE supports three concurrent write completion detection methods: Ready/Busy# (RY/BY#) open-drain output, Data# Polling (DQ7), and Toggle Bit (DQ6). RY/BY# goes high when ready; DQ7 toggles during operation and stabilizes to true data upon completion; DQ6 toggles continuously until operation ends. These mechanisms allow flexible host-side timing control without fixed delays. All three are fully documented for SST39VF802C-70-4C-EKE in Sections 8–9 of DS25041A.
Is SST39VF802C-70-4C-EKE pin-compatible with SST39VF801C?
No, SST39VF802C-70-4C-EKE and SST39VF801C are not pin-compatible replacements due to differing boot block architectures - SST39VF802C-70-4C-EKE protects the top 8 KWord (7E000H–7FFFFH), while SST39VF801C protects the bottom 8 KWord (00000H–01FFFH). Although both share identical pinouts and command sets, substituting one for the other without firmware and address map validation risks corrupting protected regions. The SST39VF802C-70-4C-EKE datasheet confirms this distinction in Table 4 and Section 10.
What package type is used in SST39VF802C-70-4C-EKE?
SST39VF802C-70-4C-EKE uses a 48-lead TSOP (Thin Small Outline Package) with 12 mm × 20 mm body dimensions and standard JEDEC MO-141AC footprint. This is explicitly stated in the "Packages Available" section of DS25041A and confirmed in Figure 2 (Pin Assignments for 48-Lead TSOP). The "-EKE" suffix denotes this TSOP variant; alternative packages (TFBGA/WFBGA) use different suffixes (e.g., "-B3K", "-MAQ").
