Product details
Overview
SST39WF1601-70-4I-MBQE-T from Silicon Storage Technology is a 16 Mbit (1M × 16) Multi-Purpose Flash Plus (MPF+) memory IC operating at 1.65–1.95 V, featuring 70 ns read access time, bottom 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface - used for firmware storage in industrial microcontroller boot systems.
For engineers reviewing the SST39WF1601-70-4I-MBQE-T datasheet, SST39WF1601-70-4I-MBQE-T pinout, SST39WF1601-70-4I-MBQE-T application, or SST39WF1601-70-4I-MBQE-T equivalent, key selection criteria include single-supply 1.65–1.95 V operation, bottom-boot block protection mapping to address 000000H–007FFFH, 100,000-cycle endurance, and 48-ball WFBGA (5 mm × 6 mm) packaging with RST# and WP# control pins.
Technical Context
The SST39WF1601-70-4I-MBQE-T implements SuperFlash split-gate technology enabling fixed erase/program times independent of cycle count, eliminating software de-rating. It supports JEDEC-standard command sets including CFI Query, Software ID Entry, and Security ID programming with factory-locked 128-bit SST ID and user-programmable 128-bit segment.
Its architecture features uniform 2 KWord sectors (512 total) and 32 KWord blocks (32 total), with hardware block protection activated when WP# is low on the bottom 32 KWord region. Erase-suspend/resume capability allows concurrent read/program operations outside suspended sectors during active erase.
Key Specifications

Key Features
| Feature | Design Value |
|---|---|
| Erase-suspend/resume | Enables real-time read access to non-suspended sectors during active erase - critical for interrupt-driven firmware updates |
| Auto Low Power mode | Reduces active read current from 9 mA to 5 µA after valid read - cuts dynamic power in always-on embedded systems |

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), top-boot block protection, 70 ns access, 48-pin TSOP | Requires level-shifting for 1.8 V SoCs; top-boot protection covers different address range (0xF8000–0xFFFFF) | Select when legacy 3 V systems or TSOP packaging is mandated; not drop-in due to voltage and boot-block mismatch |
| S29GL032N90TFIR20 | 3.0 V supply, 32 Mbit density, 90 ns access, 64-ball BGA, no RST# pin | Larger capacity but slower timing; lacks hardware reset pin needed for safe erase abort in safety-critical designs | Choose for higher density where 90 ns read latency is acceptable and RST# functionality is not required |

FAQ
What is the exact memory organization of the SST39WF1601-70-4I-MBQE-T?
The SST39WF1601-70-4I-MBQE-T is organized as 1M × 16, delivering 16 Mbit (2 MB) of storage. It uses uniform 2 KWord sectors (512 total) and 32 KWord blocks (32 total), with bottom 32 KWord hardware block protection covering address range 000000H–007FFFH. This structure is confirmed in the EOL datasheet Section "PRODUCT DESCRIPTION" and Table 2.
Does the SST39WF1601-70-4I-MBQE-T support JEDEC-standard commands and CFI?
Yes, the SST39WF1601-70-4I-MBQE-T fully supports JEDEC-standard pin assignments and command sets, including Common Flash Interface (CFI) Query modes - both original SST CFI and general CFI. The device responds to CFI entry commands at address 5555H (98H) or 55H (98H), with CFI data readable per Tables 7–9 in the datasheet.
How does hardware block protection work on the SST39WF1601-70-4I-MBQE-T?
Hardware block protection on the SST39WF1601-70-4I-MBQE-T is activated when the WP# pin is pulled low, locking the bottom 32 KWord (000000H–007FFFH) against program and erase operations. If WP# is left floating, an internal pull-up holds it high, leaving the boot block unprotected. This behavior is explicitly defined in the "Hardware Block Protection" section and Table 2 of the datasheet.
What are the valid supply voltage and operating temperature ranges for the SST39WF1601-70-4I-MBQE-T?
The SST39WF1601-70-4I-MBQE-T operates from 1.65 V to 1.95 V DC and is rated for the industrial temperature range of –40°C to +85°C. These values are specified in the "Operating Range" table (page 9) and confirmed in DC Operating Characteristics (Table 10), where VDD = 1.65–1.95 V applies to all commercial and industrial variants.
Can the SST39WF1601-70-4I-MBQE-T be used in place of the SST39WF1602?
No - the SST39WF1601-70-4I-MBQE-T and SST39WF1602 differ in hardware block protection direction: SST39WF1601 protects the bottom 32 KWord, while SST39WF1602 protects the top 32 KWord (0F8000H–0FFFFFH). Their device IDs also differ (BF274B vs. BF274A), and they are not functionally interchangeable without board-level address mapping changes.
