Product details
Overview
SST39VF802C-70-4C-EKE-T from Microchip Technology is a 8 Mbit (512K × 16) CMOS Multi-Purpose Flash Plus memory IC with SuperFlash® technology, operating at 2.7–3.6 V, featuring 70 ns read access time, hardware top-block protection (7E000H–7FFFFH), and JEDEC-standard x16 parallel interface for embedded firmware storage in industrial controllers.
For engineers reviewing the SST39VF802C-70-4C-EKE-T datasheet, SST39VF802C-70-4C-EKE-T pinout, SST39VF802C-70-4C-EKE-T application, or SST39VF802C-70-4C-EKE-T equivalent, key selection considerations include boot-block architecture, sector/block-erase timing (18 ms typical), RY/BY# status signaling, and TSOP-48 package compatibility with legacy 16-bit memory buses.
Technical Context
This device implements a split-gate SuperFlash® cell architecture enabling fixed erase/program times independent of cycle count, eliminating software de-rating. It supports three write-status detection methods: Data# Polling (DQ7), Toggle Bits (DQ6/DQ2), and open-drain RY/BY# output requiring external 10–100 kΩ pull-up.
Command execution follows JEDEC-standard six-byte sequences for sector/block/chip-erase and three-byte sequences for word-program and security ID operations. Hardware block protection is activated via WP# low on the top 8 KWord (7E000H–7FFFFH), and reset is managed through active-low RST# with TRP ≥ 100 ns.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16) - supports 16-bit data bus systems without byte-lane multiplexing |
| Read Access Time | 70 ns - enables direct connection to microcontrollers with ≤14 MHz bus timing |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V logic rails and tolerant of brown-out conditions down to 2.7 V |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years in industrial deployments |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage applications |
| Erase Time | 18 ms (sector/block), 40 ms (chip) - enables rapid reconfiguration during manufacturing or service provisioning |
| Active Current | 5 mA typical at 5 MHz - low enough for battery-backed operation in standby-aware systems |
| Standby Current | 3 µA typical - supports ultra-low-power sleep modes in portable or energy-harvested devices |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, standard JEDEC x16 flash footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus supporting full 512K-word addressing; AMS = A18 for block/sector 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 |
| 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/data on rising/falling edges per JEDEC sequence |
| WP# | Write Protect | Active-low hardware lock for top 8 KWord boot block (7E000H–7FFFFH); floating = internally pulled high |
| RST# | Reset | Active-low hardware reset; terminates ongoing erase/program and forces return to read mode |
| RY/BY# | Ready/Busy# | Open-drain status output; low = active erase/program, requires external pull-up resistor |
| VDD | Power Supply | 2.7–3.6 V supply; powers core logic and SuperFlash® array |
| VSS | Ground | Reference ground for all I/O and core circuitry |
| NC | No Connection | Unbonded pins (A13, A9, A12, A8, A17, A4, A14, A10, A15, A11, A5, A1); must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Fixed 7 µs word-program and 18 ms erase times across full lifecycle - eliminates runtime degradation compensation in firmware |
| Top Boot Block Protection | Hardware-enforced lock on 7E000H–7FFFFH region - prevents accidental overwrite of bootloader code during field updates |
| Erase-Suspend/Resume | Allows read access to non-suspended sectors during erase - enables real-time diagnostics or UI responsiveness during firmware update |
| Security ID Space | Factory-programmed 128-bit ID + user-programmable 128-word space - supports device authentication and secure provisioning |
| CFI Compliance | JEDEC Common Flash Interface support - enables auto-detection and standardized driver integration in BIOS/bootloader stacks |
| Auto Low Power Mode | Reduces active read current from 5 mA to 3 µA after valid access - cuts dynamic power by >99% during idle polling loops |

Use Value: Sector-erase capability (2 KWord uniform blocks) allows granular map updates without full reflash, reducing service downtime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel-interface flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF801C-70-4C-EKE-T | Bottom boot block (00000H–01FFFH), identical timing, voltage, and pinout | Used where bootloader resides in lowest memory region instead of top region | Select when system architecture requires protected boot code at address zero rather than top-of-memory |
| MX29LV800CTTI-70G | Same density, 70 ns access, but uses different command set (no CFI), no Erase-Suspend, no Security ID | Lacks suspend/resume and secure ID features; suitable for cost-sensitive, static firmware applications | Choose for legacy designs already using Macronix command protocol and where advanced features are unused |
Compared with SST39VF802C-70-4C-EKE-T, SST39VF801C-70-4C-EKE-T offers mirrored boot-block placement for bottom-address firmware, while MX29LV800CTTI-70G provides basic functionality at lower cost but omits SuperFlash® advantages like fixed timing and security extensions.

FAQ
What is the boot block configuration of SST39VF802C-70-4C-EKE-T?
The SST39VF802C-70-4C-EKE-T implements top boot block protection covering address range 7E000H–7FFFFH (8 KWord). This region is hardware-protected when WP# is driven low, preventing accidental erase or program during system operation. The device does not support bottom boot configuration - that function is assigned to SST39VF801C variants.
Does SST39VF802C-70-4C-EKE-T require an external VPP voltage for programming?
No, SST39VF802C-70-4C-EKE-T does not require external VPP. It generates internal high-voltage programming pulses using its on-chip charge pump, operating solely from the 2.7–3.6 V VDD supply. This simplifies board design by eliminating dedicated VPP regulators or routing.
How is write completion detected on SST39VF802C-70-4C-EKE-T?
SST39VF802C-70-4C-EKE-T supports three concurrent write-status detection methods: Data# Polling (DQ7 toggles until completion), Toggle Bits (DQ6 toggles during operation), and Ready/Busy# (RY/BY# open-drain output pulled low during erase/program). All methods are valid after the final WE# pulse in the command sequence.
Can SST39VF802C-70-4C-EKE-T be used in place of SST39VF801C-70-4C-EKE-T?
No, SST39VF802C-70-4C-EKE-T is not a drop-in replacement for SST39VF801C-70-4C-EKE-T due to differing boot block locations: SST39VF802C protects the top 8 KWord (7E000H–7FFFFH), while SST39VF801C protects the bottom 8 KWord (00000H–01FFFH). Software and hardware address mapping must be verified before substitution.
What package type is used in SST39VF802C-70-4C-EKE-T?
SST39VF802C-70-4C-EKE-T uses a 48-lead TSOP (Thin Small Outline Package) with 12 mm × 20 mm body size and standard JEDEC x16 flash pinout. The "-EKE-T" suffix explicitly denotes this TSOP-48 variant, distinguishing it from TFBGA or WFBGA versions of the same device.
