Product details
Overview
SST39WF1602-70-4C-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 and configuration storage in space-constrained, 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-MAQE-T datasheet, SST39WF1602-70-4C-MAQE-T pinout, SST39WF1602-70-4C-MAQE-T application, or SST39WF1602-70-4C-MAQE-T equivalent, key selection considerations include its 48-ball WFBGA (4 mm × 6 mm) package, JEDEC-compliant x16 asynchronous interface, 100,000-cycle endurance, and support for CFI query and Security ID programming - all critical for automotive infotainment boot code, industrial firmware updates, and IoT device configuration storage.
Technical Context
The SST39WF1602-70-4C-MAQE-T implements SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its command-set architecture follows JEDEC-standard flash pin assignments and supports both SST-specific and general CFI Query modes for system compatibility.
It integrates hardware block protection via WP# tied low to protect the top 32 KWord (0F8000H–0FFFFFH), RST# for hardware reset to Read mode, and dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits) for precise write completion monitoring during Word-Program (28 µs typical), Sector-Erase (36 ms), Block-Erase (36 ms), and Chip-Erase (140 ms) operations.

Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, AEC-Q100-qualified option available.
| 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 during erase commands. |
| 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 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 | Controls timing of command/address/data latching; falling edge latches address, rising edge latches data per JEDEC standard. |
| WP# | Hardware Write Protect | Low = locks top 32 KWord boot block (0F8000H–0FFFFFH); floating = internally pulled high (unprotected). |
| RST# | Reset Input | Active-low hardware reset; forces immediate return to Read mode; TRP ≥ 100 ns required for reliable abort of in-progress erase/program. |
| VDD | Power Supply | 1.65–1.95 V core supply; internal VPP generation eliminates external charge pump requirement. |
| VSS | Ground | Two dedicated ground balls (pins E8, H1) ensure stable reference for low-noise operation in mixed-signal environments. |
| NC | No Connect | Unbonded pins (e.g., A13, A18 on WFBGA layout); must remain unconnected per design - no pull-up/down or routing. |
Key Features

FAQ
What is the operating voltage range for SST39WF1602-70-4C-MAQE-T?
The SST39WF1602-70-4C-MAQE-T operates exclusively from 1.65 V to 1.95 V. This narrow 1.8 V nominal range eliminates compatibility with 3.3 V or 2.5 V systems and requires strict regulation - underscoring why SST39WF1602-70-4C-MAQE-T is specified for modern low-power SoCs and battery-backed applications where voltage scaling is critical.
Does SST39WF1602-70-4C-MAQE-T support hardware block protection, and how is it configured?
Yes, SST39WF1602-70-4C-MAQE-T implements top-block hardware protection for the upper 32 KWord (0F8000H–0FFFFFH). Protection is enabled by pulling WP# low; leaving WP# floating applies an internal pull-up, disabling protection. This differs from SST39WF1601, which protects the bottom block - confirming SST39WF1602-70-4C-MAQE-T's role in safeguarding boot code stored at highest addresses.
How does the Auto Low Power mode function in SST39WF1602-70-4C-MAQE-T?
SST39WF1602-70-4C-MAQE-T enters Auto Low Power mode automatically after a valid read cycle completes, reducing active current from 5 mA to 5 µA. It exits instantly on any address or control signal transition - with zero access time penalty - making SST39WF1602-70-4C-MAQE-T ideal for burst-read applications like graphics controller frame buffer access where idle power dominates total consumption.
Can SST39WF1602-70-4C-MAQE-T be used in automotive applications, and what qualifications apply?
Yes, SST39WF1602-70-4C-MAQE-T has an AEC-Q100-qualified variant (same base part number with automotive suffix), rated for -40°C to +85°C operation and qualified for automotive infotainment and body control modules. The SST39WF1602-70-4C-MAQE-T itself is commercial-grade (0°C to +70°C), but its design - including 100-year retention and 100,000-cycle endurance - meets foundational automotive reliability requirements even in non-qualified versions.
What command sequences are required to program or erase SST39WF1602-70-4C-MAQE-T?
SST39WF1602-70-4C-MAQE-T requires JEDEC-standard software data protection: Word-Program uses a 3-byte sequence (5555H/AAH → 2AAAH/55H → 5555H/A0H), while Sector-Erase uses a 6-byte sequence (5555H/AAH → 2AAAH/55H → 5555H/80H → 5555H/AAH → 2AAAH/55H → SAX/30H). These sequences prevent accidental writes - a mandatory safeguard confirmed in the SST39WF1602-70-4C-MAQE-T datasheet and enforced by on-chip logic.
