Product details
Overview
SST39WF1601-70-4I-MAQE-T from Microchip Technology (formerly Silicon Storage Technology) is a 16 Mbit (1M × 16) Multi-Purpose Flash Plus (MPF+) memory IC designed for embedded program, configuration, and data storage. It operates from a single 1.65–1.95 V supply, delivers 70 ns read access time, and features bottom-block hardware write protection (protecting address range 000000H–007FFFH). It is used in industrial microcontroller boot code storage where low-voltage operation and long-term data retention are critical.
For engineers reviewing the SST39WF1601-70-4I-MAQE-T datasheet, SST39WF1601-70-4I-MAQE-T pinout, SST39WF1601-70-4I-MAQE-T application, or SST39WF1601-70-4I-MAQE-T equivalent, key selection considerations include its 48-ball WFBGA (4 mm × 6 mm) package, JEDEC-standard x16 asynchronous interface, bottom-boot block protection scheme, and SuperFlash technology enabling fixed 28 µs word-program and 36 ms sector/block-erase times independent of endurance cycles.
Technical Context
This device implements a CMOS SuperFlash architecture with split-gate cells and thick-oxide tunneling injectors, delivering superior reliability over conventional flash technologies. Its command-set complies with JEDEC standard pin assignments and supports CFI Query mode for system identification and compatibility.
It uses latched address/data I/O with tri-state outputs controlled by CE# and OE#, and integrates hardware reset (RST#), write protect (WP#), and erase-suspend/resume functionality. The internal VPP generation eliminates need for external high-voltage programming supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words) - supports full firmware images or large configuration tables in compact footprint. |
| Read Access Time | 70 ns - enables direct execution (XIP) from flash in performance-sensitive MCU applications without wait states at moderate clock speeds. |
| Supply Voltage | 1.65–1.95 V - compatible with modern low-power SoCs and battery-backed systems; eliminates level-shifting requirements. |
| Endurance | 100,000 program/erase cycles - sufficient for field-upgradable firmware with infrequent updates over product lifetime. |
| Data Retention | >100 years - ensures nonvolatile storage integrity across extended shelf life and operational lifespan without refresh. |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) - allows fine-grained updates while minimizing wear on unrelated memory regions. |
| Write Protection | Hardware bottom-block protection (32 KWord / 64 KB) via WP# pin - safeguards boot loader region against accidental overwrite during field updates. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, AEC-Q100-qualified option available. Pinout conforms to JEDEC x16 flash standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 16-bit address bus (A0–A15) plus 4 MSBs (A16–A19); AMS = A19 for sector/block selection. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; latched internally during writes; tri-stated when CE# or OE# is high. |
| CE# | Chip Enable | Active-low chip select; device enters standby (5 µA) when high; required low for all operations. |
| OE# | Output Enable | Active-low output gate; controls data bus visibility during reads; must be low with CE# for valid output. |
| WE# | Write Enable | Active-low control for write cycles; latches address/data edges; initiates internal program/erase timing. |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block (000000H–007FFFH); floating = unprotected (internal pull-up). |
| RST# | Reset | Active-low hardware reset; forces return to read mode; terminates in-progress erase/program safely. |
| VDD | Power Supply | 1.65–1.95 V core supply; powers logic and SuperFlash array; no external VPP required. |
| VSS | Ground | Reference ground for all signals and internal circuitry; two dedicated balls for noise immunity. |
| NC | No Connect | Unbonded balls (e.g., A18, A19 in TFBGA layout); must remain unconnected per design. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide injector enables fixed 28 µs word-program and 36 ms erase times - no software de-rating needed over lifetime. |
| Auto Low Power Mode | Reduces active read current from 5 mA to 5 µA after valid access - cuts dynamic power by 99.9% during idle polling or burst reads. |
| Erase-Suspend/Resume | Allows real-time read/program from non-suspended sectors during background erase - essential for multitasking RTOS firmware updates. |
| Security ID | 256-bit space (128-bit factory + 128-bit user) with lock-out capability - enables secure device authentication and anti-cloning in OEM deployments. |
| CFI Compliance | Supports both SST-specific and general CFI Query modes - ensures plug-and-play compatibility with standard flash programmers and BIOS/UEFI firmware stacks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601-70-4I-B3K | Same 16 Mbit x16 density and SuperFlash core, but in 48-ball TFBGA (6 mm × 8 mm); 70 ns access, identical voltage and endurance specs. | Larger footprint increases PCB area; better thermal dissipation in high-ambient industrial enclosures. | Select when board layout allows larger package or thermal margin is prioritized over miniaturization. |
| MX29LV160DTTC-70G | 16 Mbit x16 NOR flash from Macronix; 70 ns access, 2.7–3.6 V supply; lacks Auto Low Power mode and erase-suspend; JEDEC-compatible but different command set. | Requires level-shifting for 1.8 V systems; no hardware bottom-block protection - relies on software locking only. | Choose only if existing design already uses MX29LV family and voltage rail permits 2.7 V minimum; not drop-in compatible. |
Compared with SST39WF1601-70-4I-MAQE-T, the SST39VF1601 offers identical functionality in a thermally robust package, while the MX29LV160DTTC requires voltage adaptation and lacks critical reliability features like erase-suspend and hardware boot protection - making it unsuitable for safety-critical or ultra-low-power designs.

Does the SST39WF1601-70-4I-MAQE-T require an external VPP voltage for programming?
No, the SST39WF1601-70-4I-MAQE-T does not require an external VPP voltage. It generates all necessary high-voltage programming pulses internally using its SuperFlash technology, enabling full read and write operation from a single 1.65–1.95 V supply - a key advantage over legacy NOR flash devices.
How does the Auto Low Power mode function in the SST39WF1601-70-4I-MAQE-T?
The SST39WF1601-70-4I-MAQE-T automatically enters Auto Low Power mode after a valid read cycle, reducing active current from 5 mA to 5 µA. It exits instantly on any address or control signal transition with no access time penalty. This feature is enabled by default and requires no software configuration.
Can the SST39WF1601-70-4I-MAQE-T be used in automotive applications?
Yes - while the base SST39WF1601-70-4I-MAQE-T is rated for industrial temperature (–40°C to +85°C), AEC-Q100-qualified variants of the same device family are available. These qualified versions undergo rigorous stress testing for automotive use cases including instrument clusters and body control modules.
What is the purpose of the Security ID feature in the SST39WF1601-70-4I-MAQE-T?
The SST39WF1601-70-4I-MAQE-T includes a 256-bit Security ID: 128 bits factory-programmed and locked by SST, and 128 bits user-programmable.
