Product details
Overview
SST39WF1601-70-4I-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/data storage in low-voltage systems. It operates from 1.65–1.95 V, delivers 70 ns read access time, supports bottom-block hardware write protection (000000H–007FFFH), and features sector/block/chip erase with erase-suspend/resume capability.
For engineers reviewing the SST39WF1601-70-4I-B3KE datasheet, SST39WF1601-70-4I-B3KE pinout, SST39WF1601-70-4I-B3KE application, or SST39WF1601-70-4I-B3KE equivalent, key selection considerations include its 48-ball WFBGA (4 mm × 6 mm) package, JEDEC-compliant x16 asynchronous interface, SuperFlash technology-based reliability (100,000 program/erase cycles, >100-year data retention), and dual status detection (DQ6 toggle, DQ7 polling).
Technical Context
The SST39WF1601-70-4I-B3KE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its command set follows JEDEC-standard flash pin assignments and supports software data protection via three-byte (program) and six-byte (erase) sequences.
It integrates hardware block protection on the bottom 32 KWord (256 KB) boot sector, RST#-driven hardware reset to Read mode, and CFI Query support (SST and general modes) for system-level identification and configuration. The device uses latched address/data and provides Auto Low Power mode (5 µA standby, 5 µA auto-low-power current) triggered by valid Read operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words) - supports full firmware image or configuration storage in space-constrained designs. |
| Read Access Time | 70 ns - enables direct execution (XIP) from flash in microcontroller-based systems without performance penalty. |
| Supply Voltage | 1.65–1.95 V - compatible with modern ultra-low-voltage SoCs and battery-powered applications. |
| Endurance | 100,000 program/erase cycles - ensures long-term field reliability for infrequently updated firmware or calibration data. |
| Data Retention | >100 years - eliminates need for periodic refresh or backup in sealed industrial or automotive modules. |
| Erase Granularity | 2 KWord sectors (4 KB) / 32 KWord blocks (64 KB) - allows fine-grained updates without erasing entire device. |
| Write Protection | Hardware bottom-block (000000H–007FFFH) via WP# - prevents accidental overwrite of boot code during field firmware upgrades. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, AEC-Q100 qualified option available.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 100% addressable 1M-word space; A19 is MSB; sector/block selection uses A0–A11 (sector) or A0–A15 (block). |
| DQ0–DQ15 | Data I/O | x16 bidirectional bus; outputs tri-stated when CE# or OE# high; latched internally during writes. |
| CE# | Chip Enable | Active-low chip select; device enters standby (5 µA) when high; required low for all operations except Write Inhibit. |
| OE# | Output Enable | Active-low output gate; controls data bus drive; must be low with CE# for valid reads. |
| WE# | Write Enable | Controls timing of command/address/data latching; falling edge latches address, rising edge latches data. |
| WP# | Write Protect | Hardware lock for bottom 32 KWord boot block; grounded = protection enabled; floating = internal pull-up disables protection. |
| RST# | Reset | Hardware abort of in-progress erase/program; forces return to Read mode within TRP (min 100 ns). |
| VDD | Power Supply | 1.65–1.95 V core supply; internal VPP generation eliminates external high-voltage requirement. |
| VSS | Ground | Reference for all I/O and core logic; two dedicated VSS balls ensure stable low-impedance return path. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows real-time read access to non-suspended sectors during active erase, enabling background firmware validation. |
| Security ID | 256-bit factory + user programmable ID space (128-bit each); user segment lockable to prevent tampering. |
| Auto Low Power Mode | Reduces active read current from 5 mA to 5 µA after valid access-cuts power by 1000× during idle intervals. |
| End-of-Write Detection | Dual-status signaling (DQ6 toggle + DQ7 polling) enables deterministic host software timing without fixed delays. |
| SuperFlash Reliability | Fixed 36 ms sector/block erase and 28 µs word-program times across full lifecycle-no software de-rating needed. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160ETTI-70G | 3.0 V supply (2.7–3.6 V), 70 ns access, top-boot configuration, no erase-suspend, no Security ID. | Lacks low-voltage operation and advanced features; suitable only where 3 V rail is available and boot protection direction matches. | Select only if legacy 3 V design requires pin-compatible replacement and erase-suspend/Security ID are unnecessary. |
| S29GL032N90TFI010 | 3.0 V supply, 90 ns access, 32 Mbit density, bottom-boot, no Auto Low Power mode, no Security ID. | Higher density but slower access and higher voltage; lacks power optimization and security features critical for battery/IoT use. | Consider only when 32 Mbit capacity is mandatory and system can tolerate 90 ns latency and 3 V operation. |
Compared with MX29LV160ETTI-70G and S29GL032N90TFI010, the SST39WF1601-70-4I-B3KE uniquely combines 1.65–1.95 V operation, 70 ns speed, bottom-boot hardware protection, erase-suspend, and Security ID in a 48-ball WFBGA-making it optimal for next-generation ultra-low-power, secure, and AEC-Q100-ready designs.

FAQ
What is the exact memory organization of the SST39WF1601-70-4I-B3KE?
The SST39WF1601-70-4I-B3KE is organized as 1,048,576 words × 16 bits (1M × 16), totaling 16 Mbit. Its address space spans A0–A19, with bottom 32 KWord (000000H–007FFFH) designated as hardware-protected boot block. This structure supports direct x16 bus interfacing with microcontrollers and DSPs without data width translation.
Does the SST39WF1601-70-4I-B3KE support both top-boot and bottom-boot configurations?
No-the SST39WF1601-70-4I-B3KE supports bottom-boot hardware block protection only, covering addresses 000000H–007FFFH. The top-boot variant is the SST39WF1602. This distinction is hardwired in silicon; the SST39WF1601-70-4I-B3KE cannot be configured as top-boot via software or pin strapping.
How does the Auto Low Power mode function in the SST39WF1601-70-4I-B3KE?
The SST39WF1601-70-4I-B3KE enters Auto Low Power mode automatically after a valid Read operation completes, reducing active current from 5 mA to 5 µA. It exits instantly on any address or control signal transition (e.g., CE# toggle) with zero access time penalty-ideal for burst-read applications with intermittent activity.
Can the Security ID of the SST39WF1601-70-4I-B3KE be reprogrammed after initial programming?
The factory-programmed 128-bit Security ID segment is permanently locked and immutable. The user-programmable 128-bit segment can be written once using the Security ID Word-Program command; after executing the User Sec ID Program Lock-Out command, further writes are disabled. Unlocked bits ('1') may be overwritten with '0', but '0' bits cannot be restored to '1'.
What JEDEC standards does the SST39WF1601-70-4I-B3KE comply with?
The SST39WF1601-70-4I-B3KE conforms to JEDEC Standard JESD21-C for Flash EEPROM pin assignments and command sets, and supports both SST-specific and general Common Flash Interface (CFI) Query modes per JEDEC publication 100. It also meets RoHS Directive 2011/65/EU and AEC-Q100 stress test requirements for automotive qualification.
