Product details
Overview
SST39WF1602-70-4I-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/data storage in space-constrained industrial and automotive systems. It operates from a single 1.65–1.95 V supply, delivers 70 ns read access time, supports hardware top-block protection (32 KWord), and features JEDEC-standard x16 asynchronous interface with CFI compliance.
For engineers reviewing the SST39WF1602-70-4I-MAQE-T datasheet, SST39WF1602-70-4I-MAQE-T pinout, SST39WF1602-70-4I-MAQE-T application, or SST39WF1602-70-4I-MAQE-T equivalent, key selection considerations include its 1.65–1.95 V single-supply operation, top-boot block protection architecture, 100,000-cycle endurance, 100-year data retention, and 48-ball WFBGA (4 mm × 6 mm) packaging suitable for high-density PCB layouts.
Technical Context
The SST39WF1602-70-4I-MAQE-T implements SuperFlash split-gate cell technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its command set conforms to JEDEC standard pin assignments and supports Software Data Protection (SDP) via three- and six-byte sequences for word-program and sector/block-erase operations.
It integrates hardware block protection via WP# pin (active-low for top 32 KWord boot block), hardware reset via RST#, Auto Low Power mode (5 µA standby), and dual status detection (DQ7 Data# Polling and DQ6/DQ2 Toggle Bits) for write completion monitoring. The device supports CFI Query modes (SST and general) and Security ID (128-bit factory + 128-bit user programmable).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16 bits); enables compact firmware storage without external address multiplexing. |
| Read Access Time | 70 ns; supports high-speed CPU interface at up to ~14 MHz sustained random read throughput. |
| Supply Voltage | 1.65–1.95 V; compatible with low-voltage SoC I/O domains and eliminates need for level shifters. |
| Endurance | 100,000 program/erase cycles; ensures reliable field updates over product lifetime in industrial control firmware. |
| Data Retention | >100 years at 85°C; validated for long-term unpowered storage in automotive ECUs and medical devices. |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB); allows fine-grained firmware patching and robust recovery partitioning. |
| Protection Mode | Hardware top-block protection (0F8000H–0FFFFFH); prevents accidental overwrite of bootloader code during field upgrades. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, AEC-Q100 qualified (industrial temperature range −40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 100% address bus latching on CE#/WE# edge; AMS = A19 for full 1M-word addressing. |
| DQ0–DQ15 | Data I/O | Bi-directional x16 bus with tri-state output control via OE# and CE#; latched internally during writes. |
| CE# | Chip Enable | Active-low chip select; device enters standby (5 µA) when high; required for all operations. |
| OE# | Output Enable | Active-low output gate; controls data bus tristate; must be low with CE# for valid reads. |
| WE# | Write Enable | Active-low write strobe; latches address/data and initiates internal program/erase timing sequences. |
| WP# | Write Protect | Active-low hardware lock for top 32 KWord boot block; floating = internally pulled high (unprotected). |
| RST# | Reset | Active-low hardware abort; terminates ongoing erase/program and forces return to read mode within TRP. |
| VDD | Power Supply | 1.65–1.95 V core supply; internal VPP generation eliminates external high-voltage charge pump. |
| VSS | Ground | Reference for all I/O and core logic; two dedicated VSS balls ensure low-noise power integrity. |
| NC | No Connect | Unbonded balls (e.g., A18, A19 in some pinouts); no electrical function or routing requirement. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide tunneling injector enables fixed 28 µs word-program and 36 ms sector-erase times across full lifecycle. |
| Erase-Suspend/Resume | Allows real-time read access or programming in non-suspended sectors during active erase, critical for fail-safe firmware update routines. |
| Security ID | 256-bit space (128-bit factory-locked + 128-bit user-programmable) with lock-out command; supports secure device authentication and anti-cloning. |
| Auto Low Power Mode | Automatically transitions from 5 mA active read to 5 µA standby after valid read access-no software intervention required. |
| JEDEC CFI Compliance | Supports both SST-specific and general CFI Query modes (via 5555H/98H or 55H/98H), enabling standardized flash management in multi-vendor BSPs. |

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, bottom-boot configuration, no Auto Low Power mode. | Lacks 1.8 V compatibility and energy-efficient standby; requires level-shifting for 1.8 V MCUs. | Select only if legacy 3 V system architecture prohibits voltage rail redesign. |
| S29GL032N90TFIR20 | 3.0 V supply, 90 ns access, 32 Mbit density, mirror-bit architecture, no hardware WP# pin. | Higher density but slower timing and no dedicated top-block protection; relies on software locks only. | Prefer for cost-sensitive 3 V designs where boot block security is managed in firmware. |
Compared with MX29LV160ETTI-70G and S29GL032N90TFIR20, the SST39WF1602-70-4I-MAQE-T uniquely delivers 1.65–1.95 V operation, hardware-enforced top-boot protection, and Auto Low Power mode-making it optimal for next-generation ultra-low-power industrial and automotive controllers where voltage scaling and security are mandatory.

FAQ
What is the operating voltage range for the SST39WF1602-70-4I-MAQE-T?
The SST39WF1602-70-4I-MAQE-T operates from a single 1.65 V to 1.95 V supply. This narrow 1.8 V nominal range eliminates the need for external voltage regulators or level shifters when interfacing with modern 1.8 V microcontrollers and SoCs, reducing bill-of-materials cost and board space. Operation outside this range may cause functional failure or data corruption.
How does hardware block protection work on the SST39WF1602-70-4I-MAQE-T?
The SST39WF1602-70-4I-MAQE-T implements top-block hardware protection: when the WP# pin is driven low, program and erase operations are disabled for the top 32 KWord (0F8000H–0FFFFFH), preserving bootloader code. If WP# is left floating, an internal pull-up holds it high, disabling protection. This differs from SST39WF1601, which protects the bottom block.
Does the SST39WF1602-70-4I-MAQE-T support JEDEC-standard command sets?
Yes, the SST39WF1602-70-4I-MAQE-T fully conforms to JEDEC standard pin assignments and command sets for x16 flash memories. It supports both SST-specific and general Common Flash Interface (CFI) Query modes, enabling interoperability with standardized flash management drivers in Linux, VxWorks, and bare-metal BSPs without vendor-specific extensions.
What is the significance of the "-70" in SST39WF1602-70-4I-MAQE-T?
The "-70" suffix denotes a 70 ns maximum read access time specification. This defines the worst-case delay from address/CE#/OE# stabilization to valid data on DQ0–DQ15 under specified load and voltage conditions. It guarantees deterministic timing for tight real-time read operations in safety-critical firmware execution paths.
Is the SST39WF1602-70-4I-MAQE-T qualified for automotive applications?
Yes-the "I" in SST39WF1602-70-4I-MAQE-T indicates industrial temperature grade (−40°C to +85°C), and the device is AEC-Q100 qualified per the original SST datasheet. This certification validates reliability under automotive thermal, vibration, and EMI stress conditions, making it suitable for body control modules, infotainment, and ADAS subsystems.
