Product details
Overview
SST39WF1602-70-4C-B3KE from Microchip Technology (formerly Silicon Storage Technology) is a 16 Mbit (1M × 16) Multi-Purpose Flash Plus (MPF+) memory IC designed for embedded program and configuration storage in low-voltage systems. It operates from 1.65–1.95 V, delivers 70 ns read access time, supports hardware top-block protection (32 KWord), and features sector/block/chip erase with erase-suspend/resume capability.
For engineers reviewing the SST39WF1602-70-4C-B3KE datasheet, SST39WF1602-70-4C-B3KE pinout, SST39WF1602-70-4C-B3KE application, or SST39WF1602-70-4C-B3KE equivalent, this page provides verified technical context, JEDEC-compliant x16 interface details, SuperFlash reliability metrics (100K cycles, >100-year retention), and real-world use cases in automotive infotainment boot code storage, industrial PLC firmware updates, and medical device configuration memory.
Technical Context
The SST39WF1602-70-4C-B3KE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It uses standard JEDEC x16 asynchronous command sets-including 6-byte sector/block/chip erase sequences-and supports both SST-specific and general CFI Query modes for system identification and compatibility.
Its dual status detection-Data# Polling (DQ7) and Toggle Bits (DQ6/DQ2)-enables precise end-of-write monitoring during Word-Program (28 µs typical), Sector-Erase (36 ms), Block-Erase (36 ms), and Chip-Erase (140 ms). Hardware block protection is activated via WP# grounding to lock the top 32 KWord (0F8000H–0FFFFFH), while RST# provides hardware reset to Read mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words); supports full 16-bit data bus interface without byte-lane splitting. |
| Read Access Time | 70 ns max; enables direct execution (XIP) from flash in microcontroller-based systems with ≤14 MHz bus timing. |
| Supply Voltage | 1.65–1.95 V; compatible with modern low-power SoCs and battery-backed systems requiring single-supply operation. |
| Endurance & Retention | 100,000 program/erase cycles typical; >100 years data retention at 85°C - validated for long-life industrial deployments. |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB); allows fine-grained firmware patching and robust recovery partitioning. |
| Protection Mechanism | Hardware top-block protection (WP#-enabled); prevents accidental overwrite of boot code stored in 0F8000H–0FFFFFH. |
| Security ID | 256-bit factory + user-programmable ID space (128 + 128 bits); supports secure device authentication and firmware binding. |
Pinout & Package
Package: 48-ball TFBGA (6 mm × 8 mm, 0.8 mm pitch), RoHS-compliant, AEC-Q100 qualified option available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus; AMS = A19 selects top/bottom boot block; A11 used for sector selection, A15 for block selection. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; latched internally during write; tri-stated when CE# or OE# high. |
| CE# | Chip Enable | Active-low chip select; device enters standby (5 µA) when high; required low for all operations except Auto Low Power exit. |
| OE# | Output Enable | Active-low output gate; controls data bus drive; must be low with CE# for valid read access. |
| WE# | Write Enable | Active-low control for write cycles; latches address/data on falling/rising edges per JEDEC timing; initiates internal program/erase. |
| WP# | Write Protect | Active-low hardware block lock; grounds to protect top 32 KWord (0F8000H–0FFFFFH); floating = internally pulled high = unprotected. |
| RST# | Reset | Active-low hardware reset; terminates ongoing program/erase and forces return to Read mode within TRP (min 100 ns). |
| VDD | Power Supply | 1.65–1.95 V core supply; powers internal charge pump for erase/program; no external VPP required. |
| VSS | Ground | Reference ground for all signals; two dedicated VSS balls ensure stable low-impedance return path. |
| NC | No Connect | Unbonded pins (e.g., ball E2, G1, H1); must remain unconnected per layout guidelines. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1602-70-4C-B3KE | Same 16 Mbit x16 organization but 2.7–3.6 V supply range; lacks 1.65–1.95 V ultra-low-voltage support. | Used where higher VDD simplifies power design but precludes battery-operated or energy-harvesting systems. | Select only if system VDD ≥2.7 V and backward compatibility with legacy SST39VF footprint is required. |
| MX29LV160ETTI-70G | 16 Mbit x16, 2.7–3.6 V, 70 ns access; no erase-suspend, no Security ID, bottom-block protection only. | Suitable for cost-sensitive consumer electronics where advanced protection and suspend features are unnecessary. | Choose for price-driven designs accepting reduced reliability features and no top-block or security capabilities. |
Compared with SST39WF1602-70-4C-B3KE, SST39VF1602-70-4C-B3KE trades ultra-low-voltage operation for wider supply tolerance, while MX29LV160ETTI-70G omits erase-suspend and Security ID - making SST39WF1602-70-4C-B3KE uniquely suited for safety-critical, low-power, and secure firmware storage.

FAQ
What is the guaranteed minimum endurance rating for SST39WF1602-70-4C-B3KE?
The SST39WF1602-70-4C-B3KE is rated for 100,000 program/erase cycles typical, validated across temperature and voltage corners per JEDEC JESD22-A117. This endurance applies to all supported erase granularities - sector, block, and chip - and is maintained without performance degradation due to SuperFlash's fixed-timing architecture. The SST39WF1602-70-4C-B3KE specification sheet confirms this value under "Superior Reliability" and Table 10 operating conditions.
Does SST39WF1602-70-4C-B3KE support both top and bottom hardware block protection?
No - the SST39WF1602-70-4C-B3KE supports top hardware block protection only (32 KWord, address range 0F8000H–0FFFFFH), as explicitly defined in the datasheet Table 3 and "Hardware Block Protection" section. The SST39WF1601 variant supports bottom-block protection instead. This distinction is hardwired and cannot be configured via software or pin strapping. The SST39WF1602-70-4C-B3KE datasheet states WP# activation locks only the top block.
How does the Auto Low Power mode function in SST39WF1602-70-4C-B3KE?
The SST39WF1602-70-4C-B3KE enters Auto Low Power mode automatically after a valid Read operation completes, reducing active current from ~9 mA to 5 µA. It exits instantly on any address or control signal transition (e.g., CE# toggle or A0 change) with zero access time penalty. This mode requires no software enable and is disabled only during power-up with CE# held low. The SST39WF1602-70-4C-B3KE datasheet specifies this behavior in Section "Device Operation" and Figure 4 timing diagrams.
Can SST39WF1602-70-4C-B3KE be used in AEC-Q100 qualified automotive designs?
Yes - an AEC-Q100-qualified version of SST39WF1602-70-4C-B3KE is available per the datasheet's "All devices are RoHS compliant" and "AEC-Q100-qualified devices available" statements. This qualification covers temperature grade 2 (-40°C to +105°C) and includes stress testing for reliability in automotive environments. Customers must specify the qualified variant (e.g., part marking suffix or ordering code) and verify compliance documentation with Microchip prior to design-in. The SST39WF1602-70-4C-B3KE base part itself is not automatically qualified.
What is the purpose of the Security ID feature in SST39WF1602-70-4C-B3KE?
The SST39WF1602-70-4C-B3KE includes a 256-bit Security ID space: 128 bits factory-programmed by Microchip (locked permanently) and 128 bits user-programmable (lockable post-write). It enables device authentication, firmware binding, and audit trail generation. Programming requires the Security ID Word-Program command (88H), and locking uses the User Sec ID Program Lock-Out command. Neither segment is erasable. This feature is documented in Section "Security ID" and Table 6 of the SST39WF1602-70-4C-B3KE datasheet.
