Product details
Overview
SST39WF1601-70-4I-MAQE 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 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-MAQE datasheet, SST39WF1601-70-4I-MAQE pinout, SST39WF1601-70-4I-MAQE application, or SST39WF1601-70-4I-MAQE equivalent, this page provides verified functional identity, JEDEC-compliant x16 interface timing, SuperFlash reliability metrics (100K cycles, >100-year retention), and package-specific pin mapping for 48-ball WFBGA (4 mm × 6 mm).
Technical Context
The SST39WF1601-70-4I-MAQE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It uses standard microprocessor bus control (CE#, OE#, WE#) and latched address/data for asynchronous x16 operation.
It supports JEDEC-standard command sets including Software Data Protection (3-byte unlock + command), CFI Query mode (SST and general), and Security ID programming (128-bit factory + 128-bit user). Hardware block protection is implemented via WP# tied to the bottom 32 KWord boot block, and RST# enables hardware reset to Read mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1M × 16 (16 Mbit total); supports byte-wide access only via x16 data bus |
| Read Access Time | 70 ns max; defines minimum CE#/OE# setup/hold timing for reliable read cycles at full speed |
| Supply Voltage Range | 1.65–1.95 V; single supply enables direct integration into 1.8 V system rails without level shifting |
| Endurance | 100,000 program/erase cycles typical; guaranteed minimum for production qualification |
| Data Retention | Greater than 100 years at TA ≤ 85°C; validated under industrial temperature stress conditions |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB); enables fine-grained firmware updates |
| Write Protection | Hardware bottom-block protection (000000H–007FFFH) activated when WP# = low |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, AEC-Q100 qualified option available. Pinout conforms to JEDEC-standard x16 flash pin assignments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus; AMS = A19 selects top/bottom boot block during protection and erase operations |
| DQ0–DQ15 | Data I/O | x16 bidirectional data bus; tri-stated when CE# or OE# high; latched internally during write |
| 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 DQ bus drive; must be low with CE# for valid read data |
| WE# | Write Enable | Active-low write strobe; latches address/data on falling/rising edge per JEDEC timing protocol |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block (000000H–007FFFH) |
| RST# | Reset | Active-low hardware reset; terminates in-progress erase/program and forces Read mode |
| VDD | Power Supply | 1.65–1.95 V core supply; internal VPP generation eliminates external high-voltage requirement |
| VSS | Ground | Reference ground for all signals and power; two dedicated VSS balls in WFBGA package |
| NC | No Connect | Unbonded balls (e.g., A18, A19 in some positions); must remain unconnected per design |
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 |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid access - cuts dynamic power by >99% in burst-read scenarios |
| Security ID Space | 256-bit segmented ID (128-bit factory locked + 128-bit user programmable) - enables secure device authentication |
| Toggle Bit & Data# Polling | Dual status detection (DQ6 toggle + DQ7 complement) - eliminates need for fixed delay loops in host firmware |
| SuperFlash Fixed Timing | Word-program (28 µs typ), sector/block-erase (36 ms typ), chip-erase (140 ms typ) - timing stable over full lifecycle |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601-70-4C-EKE | 3.0–3.6 V operation; no 1.8 V support; identical 1M×16 organization and 70 ns timing | Requires level-shifting in 1.8 V systems; not suitable for direct replacement in low-voltage designs | Select only if system rail is 3.3 V and legacy compatibility with VF-series footprint is required |
| MX29LV160ETTI-70G | 3.0–3.6 V supply; top-boot configuration (not bottom-boot); different command set and CFI layout | Lacks bottom-block protection and erase-suspend; requires firmware adaptation for status polling | Use only when migrating from older MX29LV family and board redesign accommodates voltage and pinout changes |
Compared with SST39VF1601-70-4C-EKE and MX29LV160ETTI-70G, the SST39WF1601-70-4I-MAQE uniquely supports 1.65–1.95 V operation with bottom-boot hardware protection and erase-suspend - making it the only drop-in solution for space-constrained, low-power industrial and automotive boot memory where voltage headroom and real-time update safety are mandatory.

FAQ
What is the exact memory organization and density of the SST39WF1601-70-4I-MAQE?
The SST39WF1601-70-4I-MAQE is organized as 1M × 16, delivering 16 Mbit (2 MByte) of nonvolatile storage. Its address space spans A0–A19 (20 bits), and data is accessed exclusively via the DQ0–DQ15 x16 bus - no x8 mode or byte-select capability is supported. This matches JEDEC-standard x16 flash pinouts and timing.
Does the SST39WF1601-70-4I-MAQE support both top-boot and bottom-boot hardware protection?
No - the SST39WF1601-70-4I-MAQE supports bottom-block hardware protection only, covering address range 000000H–007FFFH (32 KWord). The top-boot variant is the SST39WF1602. WP# activation locks this bottom region against program/erase when pulled low; floating WP# defaults to high via internal pull-up, leaving the block unprotected.
What package type and dimensions does the SST39WF1601-70-4I-MAQE use?
The SST39WF1601-70-4I-MAQE is packaged in a 48-ball WFBGA with 0.5 mm pitch, measuring 4 mm × 6 mm. This compact, RoHS-compliant package is distinct from the larger 48-ball TFBGA (6 mm × 8 mm) option - pinout differs between the two, and the MAQE suffix explicitly denotes the WFBGA variant.
How does the SST39WF1601-70-4I-MAQE indicate completion of a program or erase operation?
The SST39WF1601-70-4I-MAQE provides two hardware-supported status mechanisms: Data# Polling (DQ7 toggles to complement then true data) and Toggle Bit (DQ6 toggles continuously until operation completes). Both are valid after the rising edge of the fourth (program) or sixth (erase) WE# pulse - eliminating need for fixed delays in host firmware.
Is the SST39WF1601-70-4I-MAQE qualified for automotive applications?
Yes - while the base SST39WF1601-70-4I-MAQE is rated for industrial temperature (-40°C to +85°C), AEC-Q100-qualified versions are available from Microchip. These undergo additional stress testing (HTOL, TC, ESD) and are marked with automotive-grade date codes and packaging - confirm ordering code suffixes like "-MAQE-A" for certified variants.
