Product details
Overview
SST39VF1602-70-4I-EKE-T from Microchip Technology is a 16 Mbit (1M × 16) Multi-Purpose Flash Plus (MPF+) memory IC designed for embedded firmware, boot code, and configuration storage in x16 asynchronous bus systems. It operates from 2.7–3.6 V, delivers 70 ns read access time, supports hardware top-block protection (0F8000H–0FFFFFH), and features erase-suspend/resume, security ID, and JEDEC-standard command set.
For engineers reviewing the SST39VF1602-70-4I-EKE-T datasheet, SST39VF1602-70-4I-EKE-T pinout, SST39VF1602-70-4I-EKE-T application, or SST39VF1602-70-4I-EKE-T equivalent, this page provides verified package mapping (48-lead TSOP), confirmed pin functions (e.g., WP# for top-block protection), real-world timing values (7 µs word-program, 18 ms sector-erase), and two validated alternative flash parts with documented functional and layout differences.
Technical Context
This device implements SST's SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count-unlike conventional flash where timing degrades over endurance life. Its architecture supports uniform 2 KWord sectors and 32 KWord blocks, with top-boot block protection activated when WP# is low.
The SST39VF1602-70-4I-EKE-T uses CMOS I/O compatible with JEDEC-standard x16 flash pinouts and command sets. It integrates hardware reset (RST#), auto low-power mode (3 µA standby), and dual status detection (DQ7 Data# Polling and DQ6 Toggle Bit) for reliable write-cycle monitoring without external timers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 organization), directly maps to 2 MB address space for firmware image storage |
| Read Access Time | 70 ns - enables direct execution (XIP) from flash on 14 MHz+ bus systems without wait states |
| Supply Voltage | 2.7–3.6 V - compatible with single-supply 3.3 V systems; no separate VPP required (internal generation) |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years in industrial controllers |
| Data Retention | >100 years - ensures long-term reliability in unpowered storage (e.g., BIOS, calibration tables) |
| Block Protection | Top 32 KWord (0F8000H–0FFFFFH) - safeguards boot loader region against accidental overwrite via WP# pin |
| Security ID | 256-bit (128-bit factory + 128-bit user) - enables device authentication and secure firmware binding |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm, standard pinout, die-up orientation). Pin assignments conform to JEDEC MO-141AC standard for x16 flash devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | A0–A18 select 1M × 16 locations; A19 is MSB for top-boot block addressing (0F8000H–0FFFFFH) |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; latched internally during writes; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select; must be low for all operations except standby; enables full device selection |
| OE# | Output Enable | Active-low output gate; controls data bus drive; high = high-impedance (no current draw) |
| WE# | Write Enable | Controls timing of command/data latching; falling edge samples address, rising edge samples data |
| WP# | Write Protect | Low = hardware lock of top 32 KWord boot block; floating = internal pull-up → unprotected |
| RST# | Hardware Reset | Active-low; forces immediate return to Read mode; required TRP pulse width ≥ 100 ns |
| VDD / VSS | Power / Ground | Single 2.7–3.6 V supply; decoupling mandatory within 10 mm of pins per JEDEC guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows real-time read/program from non-suspended sectors during active erase-critical for interrupt-driven firmware updates |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access-cuts power by >99% during idle polling loops |
| Uniform Sector/Block Erase | 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) enable granular firmware partitioning without wasted space |
| Toggle Bit & Data# Polling | Dual-status detection (DQ6/DQ7) eliminates need for external delay timers-reduces BOM and improves system predictability |
| CFI Query Support | Enables runtime identification of geometry, timing, and command set-essential for generic flash drivers in Linux/uClinux |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C-70-4I-EKE | Same density and speed, but bottom-block protection (000000H–007FFFH); newer revision with improved ESD rating (±4 kV HBM) | Requires PCB layout change: WP# protects bottom instead of top; incompatible for existing top-boot designs | Select only for new designs needing enhanced ESD robustness and bottom-boot architecture |
| MX29LV160CTTI-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V, but uses different command set (non-JEDEC CFI-compatible); no Security ID or erase-suspend | Lacks suspend/resume and security features; requires driver rewrite; suitable only for basic firmware storage without runtime flexibility | Choose only if legacy codebase already supports Macronix command protocol and security is not required |
Compared with SST39VF1602-70-4I-EKE-T, SST39VF1601C-70-4I-EKE shifts block protection location and adds ESD hardening, while MX29LV160CTTI-70G sacrifices advanced features for cost reduction-making the original part uniquely suited for top-boot, secure, suspend-capable embedded systems.

FAQ
What is the exact memory organization of the SST39VF1602-70-4I-EKE-T?
The SST39VF1602-70-4I-EKE-T is organized as 1M × 16 bits (16 Mbit total), yielding a 2 MB addressable space. Its top 32 KWord (64 KB) block spans addresses 0F8000H–0FFFFFH and is hardware-protected when WP# is asserted low. This matches the datasheet DS25028A section "Product Description" and Table 3.
Does the SST39VF1602-70-4I-EKE-T support both sector and block erase modes?
Yes, the SST39VF1602-70-4I-EKE-T supports uniform 2 KWord (4 KB) sector erase and 32 KWord (64 KB) block erase, with typical times of 18 ms each. These operations are initiated via JEDEC-standard six-byte command sequences, as defined in Table 6 of DS25028A.
Is the SST39VF1602-70-4I-EKE-T pin-compatible with the SST39VF1601 series?
No-the SST39VF1602-70-4I-EKE-T implements top-block protection, while SST39VF1601 variants implement bottom-block protection. Although both use identical 48-lead TSOP packages and share pinout, WP# behavior and protected address ranges differ, requiring firmware and layout review for substitution.
What voltage range does the SST39VF1602-70-4I-EKE-T require for full functionality?
The SST39VF1602-70-4I-EKE-T requires a single supply of 2.7 V to 3.6 V for all operations including read, program, and erase. Internal charge pumps generate necessary high voltages-no external VPP is needed. This is specified in the "Features" section and Table 8 of DS25028A.
How is write completion detected on the SST39VF1602-70-4I-EKE-T?
Write completion on the SST39VF1602-70-4I-EKE-T is detected using either DQ7 Data# Polling (complement-to-data toggle) or DQ6 Toggle Bit (alternating 0/1). Both methods are valid after the rising edge of the fourth WE# pulse for programming and sixth for erasing, per Figure 7 and Table 2 in DS25028A.
