Product details
Overview
SST39WF1602-70-4I-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/data 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 Erase-Suspend/Resume for real-time firmware updates in automotive instrument clusters.
For engineers reviewing the SST39WF1602-70-4I-MAQE datasheet, SST39WF1602-70-4I-MAQE pinout, SST39WF1602-70-4I-MAQE application, or SST39WF1602-70-4I-MAQE equivalent, this page provides verified functional identity, JEDEC-compliant x16 interface timing, top-boot block protection mapping, SuperFlash endurance/reliability data, and direct alternative part comparisons - all confirmed against the official DS-20005014B datasheet.
Technical Context
The SST39WF1602-70-4I-MAQE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its command set conforms to JEDEC-standard x16 flash pinouts 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 tied to WP# for 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 asynchronous write completion monitoring without CPU polling overhead.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1M × 16 (16 Mbit total); enables 16-bit parallel data bus interfacing with microcontrollers lacking external bus multiplexing. |
| Read Access Time | 70 ns; guarantees deterministic timing for real-time boot code fetch in industrial control MCUs. |
| Supply Voltage Range | 1.65–1.95 V; compatible with modern ultra-low-power SoC core rails and eliminates need for level-shifting. |
| Endurance | 100,000 program/erase cycles (typical); supports field firmware updates over 10+ years in deployed telematics units. |
| Data Retention | >100 years; ensures configuration integrity across full product lifecycle without refresh logic. |
| Block Protection | Top 32 KWord (0F8000H–0FFFFFH); safeguards bootloader region from accidental overwrite during OTA updates. |
| Erase Times | Sector/Block: 36 ms (typ), Chip: 140 ms (typ); enables fast recovery after corruption events in safety-critical modules. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, AEC-Q100 qualified for automotive use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | AMS = A19; full 20-bit address bus supports 1M-word addressing; A11 selects sector, A15 selects block. |
| DQ0–DQ15 | Data I/O | Bi-directional x16 data bus; latched internally during writes; tri-state when CE# or OE# high. |
| WE#, CE#, OE# | Control Inputs | Standard JEDEC x16 control signals; WE#/CE# falling edge latches address, rising edge latches data. |
| WP# | Hardware Protect | Active-low; enables top 32 KWord block protection when grounded; internal pull-up holds high if floating. |
| RST# | Hardware Reset | Active-low; forces immediate return to Read mode; TRP ≥ 100 ns required to abort ongoing erase/program. |
| VDD, VSS | Power/Ground | Single 1.65–1.95 V supply; no VPP pin required - internal charge pump generates programming voltage. |
| NC | No Connection | Unbonded balls per package drawings; must be left unconnected on PCB. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Erase-Resume | Allows reading or programming non-suspended sectors during active erase - critical for fail-safe bootloader operation. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid access; cuts standby power in always-on infotainment modules. |
| Security ID | 256-bit factory + user programmable ID (128 + 128 bits); enables secure device authentication and anti-cloning in Tier-1 ECUs. |
| CFI Support | Full Common Flash Interface (SST and general modes); enables OS-level flash drivers to auto-detect geometry and commands. |
| SuperFlash Reliability | Split-gate cell + thick-oxide injector yields >100-year retention and cycle-invariant timing - eliminates software de-rating. |

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 block protection, no Erase-Suspend. | Lacks Auto Low Power mode and Security ID; requires external voltage translation for 1.8 V systems. | Select only if legacy 3 V design exists and top-boot protection is not required. |
| S29GL032N90TFI010 | 3.0 V supply, 90 ns access, uniform 64 KB sectors, no hardware WP# block lock. | Relies solely on software protection; no dedicated top/bottom boot block; higher active current (15 mA). | Prefer for cost-sensitive consumer applications where AEC-Q100 and ultra-low power are not mandatory. |
Compared with MX29LV160ETTI-70G and S29GL032N90TFI010, the SST39WF1602-70-4I-MAQE uniquely combines 1.8 V operation, top-boot hardware protection, Erase-Suspend, and 5 µA Auto Low Power - making it the only drop-in solution for next-gen automotive and industrial designs requiring zero-voltage translation and real-time update resilience.

FAQ
What is the exact memory organization and density of the SST39WF1602-70-4I-MAQE?
The SST39WF1602-70-4I-MAQE is organized as 1M × 16, delivering 16 Mbit (2 MByte) of nonvolatile storage. This x16 data bus configuration enables efficient 16-bit microcontroller interfacing without byte-lane multiplexing. The device uses SuperFlash technology with a split-gate cell structure, ensuring consistent performance across its full rated endurance of 100,000 cycles.
Does the SST39WF1602-70-4I-MAQE support hardware block protection, and how is it configured?
Yes, the SST39WF1602-70-4I-MAQE implements top hardware block protection for the upper 32 KWord (0F8000H–0FFFFFH) via the WP# pin. When WP# is driven low, program and erase operations on this boot block are disabled. If left floating, an internal pull-up holds WP# high, leaving the block unprotected. This differs from the SST39WF1601, which protects the bottom 32 KWord block instead.
What are the supported operating voltage and temperature ranges for the SST39WF1602-70-4I-MAQE?
The SST39WF1602-70-4I-MAQE operates from 1.65 V to 1.95 V and is specified for industrial temperature range (–40°C to +85°C). Its AEC-Q100 qualification confirms suitability for automotive under-hood and dashboard applications. The device includes VDD power-up/down detection that inhibits writes below 1.5 V, preventing corruption during brown-out conditions.
How does the SST39WF1602-70-4I-MAQE indicate completion of Program or Erase operations?
The SST39WF1602-70-4I-MAQE provides two hardware-supported status detection methods: Data# Polling (DQ7 toggles until completion, then outputs true data) and Toggle Bits (DQ6 toggles during operation, stops when complete). DQ2 serves as a secondary toggle bit to distinguish between active erase and erase-suspend states. These mechanisms eliminate the need for fixed delay loops in host firmware.
Is the SST39WF1602-70-4I-MAQE pin-compatible with other members of the SST39WF160x family?
Yes, the SST39WF1602-70-4I-MAQE shares identical pinout, command set, and electrical specifications with the SST39WF1601, differing only in boot block location (top vs. bottom) and device ID (BF274A vs. BF274B). Both support 48-ball WFBGA and TFBGA packages, enabling board-level interchangeability where top-block protection is acceptable.
