Product details
Overview
SST39WF1601-70-4C-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 hardware bottom-block protection (000000H–007FFFH), and features uniform 2 KWord sector and 32 KWord block erase capabilities.
For engineers reviewing the SST39WF1601-70-4C-MAQE datasheet, SST39WF1601-70-4C-MAQE pinout, SST39WF1601-70-4C-MAQE application, or SST39WF1601-70-4C-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 SST39WF1601-70-4C-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 JEDEC x16 asynchronous command sets-including three-byte software data protection for word-program and six-byte sequences for sector/block/chip-erase-and supports both Data# Polling (DQ7) and Toggle Bit (DQ6/DQ2) status detection.
Hardware block protection is implemented via the WP# pin to lock the bottom 32 KWord boot block (000000H–007FFFH). The device includes RST# for hardware reset to read mode, supports CFI Query (SST and general modes), and integrates a 256-bit Security ID (128-bit factory + 128-bit user programmable) with lock-out capability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words); enables compact firmware storage without external bus widening. |
| Read Access Time | 70 ns at 1.65–1.95 V; meets real-time boot and code-execution timing in resource-constrained microcontrollers. |
| Write Voltage Range | 1.65–1.95 V single supply; eliminates need for charge pumps or auxiliary voltage rails during program/erase. |
| Endurance & Retention | 100,000 program/erase cycles typical; >100 years data retention-suitable for field-upgradable industrial firmware. |
| Erase Granularity | Uniform 2 KWord sectors (8 KB) and 32 KWord blocks (64 KB); allows fine-grained updates without full chip erase. |
| Power Consumption | 5 µA standby / 5 mA active (5 MHz typical); supports battery-backed or ultra-low-power always-on applications. |
| Protection Mechanism | Hardware bottom-block protection (WP#-enabled) + JEDEC-compliant Software Data Protection (SDP); prevents accidental corruption of boot code. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, AEC-Q100 qualified option available. Pin assignments conform to JEDEC-standard x16 flash layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus; A19–A0 select 1M-word locations; AMS = A19 per JEDEC spec. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; latched internally during write; tri-state when CE# or OE# 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 drive; high = high-impedance state. |
| WE# | Write Enable | Active-low control for write cycles; latches address/data edges per JEDEC timing protocol. |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block (000000H–007FFFH); floating = unprotected. |
| RST# | Reset | Active-low hardware reset; forces immediate return to read mode; TRP min. pulse width required. |
| VDD | Power Supply | 1.65–1.95 V core supply; internal VPP generation eliminates external high-voltage circuitry. |
| VSS | Ground | Reference ground for all I/O and core logic; two dedicated VSS balls in WFBGA package. |
| NC | No Connect | Unbonded balls (e.g., A18, A19 in some layouts); no electrical function; must be left unconnected. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows read/program from non-suspended sectors during active erase-enables real-time system responsiveness. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid access; no wake-up latency on address/control transition. |
| Security ID Space | 256-bit segmented ID (128-bit factory locked + 128-bit user programmable); supports secure device authentication. |
| CFI Query Support | Compatible with both SST-specific and JEDEC general CFI modes; enables standardized flash driver interoperability. |
| Toggle Bit Status Detection | DQ6/DQ2 toggling during erase/program provides deterministic, clockless operation status-no polling overhead. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Winbond W25Q16JVSIQ | Quad SPI interface, 3V supply (2.7–3.6 V), 16 Mbit density, no hardware WP# block protection. | Requires SPI controller and level-shifting for 1.8 V systems; lacks bottom-boot hardware lock. | Select only if SPI interface and higher voltage tolerance are acceptable; not drop-in for x16 parallel bus designs. |
| Macronix MX29GL160EHTI-70G | Parallel x16 interface, 2.7–3.6 V supply, 70 ns access, top-boot block protection (not bottom). | Same pinout but inverted boot-block location; incompatible WP# protection range for SST39WF1601 use cases. | Use only if top-boot protection suffices; verify address map alignment before PCB integration. |
Compared with Winbond W25Q16JVSIQ and Macronix MX29GL160EHTI-70G, the SST39WF1601-70-4C-MAQE uniquely combines 1.65–1.95 V operation, bottom-boot hardware protection, and JEDEC x16 compatibility-making it irreplaceable in legacy low-voltage parallel-memory designs requiring guaranteed boot-sector security.

FAQ
What is the exact memory organization of the SST39WF1601-70-4C-MAQE?
The SST39WF1601-70-4C-MAQE is organized as 1,048,576 words × 16 bits (1M × 16), totaling 16 Mbit. Its physical address space spans 000000H to 0FFFFFH, with the bottom 32 KWord (000000H–007FFFH) designated as the hardware-protected boot block. This structure is fixed and confirmed in the official datasheet DS-20005014B.
Does the SST39WF1601-70-4C-MAQE support both sector and block erase, and what are their sizes?
Yes, the SST39WF1601-70-4C-MAQE supports uniform sector erase (2 KWord = 8 KB per sector) and uniform block erase (32 KWord = 64 KB per block), as verified in Table 1 and Section 6 of DS-20005014B. Sector-erase time is 36 ms typical; block-erase time is also 36 ms typical-both independent of accumulated cycle count due to SuperFlash technology.
How does hardware write protection work on the SST39WF1601-70-4C-MAQE?
Hardware write protection on the SST39WF1601-70-4C-MAQE is enabled by pulling the WP# pin low, which locks the bottom 32 KWord boot block (000000H–007FFFH) against program and erase operations. If WP# is left floating, an internal pull-up holds it high, disabling protection. This behavior is explicitly defined in Table 3 and Section 9 of DS-20005014B.
Is the SST39WF1601-70-4C-MAQE compatible with standard JEDEC x16 flash command sets?
Yes, the SST39WF1601-70-4C-MAQE conforms fully to JEDEC-standard pin assignments and command sets for x16 asynchronous flash memories, including software data protection sequences, CFI Query modes, and Product Identification protocols. This compatibility is stated on page 2 and validated in Tables 5–6 of DS-20005014B.
What package type is used for the SST39WF1601-70-4C-MAQE suffix "MAQE"?
The "MAQE" suffix denotes the 48-ball WFBGA package (4 mm × 6 mm), as confirmed in Figure 3 and Section 1 of DS-20005014B. This differs from the TFBGA variant (suffix "MAQ") and is explicitly listed under "Packages Available" on page 1 of the datasheet.
