Product details
Overview
SST39WF1602-70-4I-B3KE-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 (0F8000H–0FFFFFH), and features sector/block/chip erase with erase-suspend/resume capability.
For engineers reviewing the SST39WF1602-70-4I-B3KE-T datasheet, SST39WF1602-70-4I-B3KE-T pinout, SST39WF1602-70-4I-B3KE-T application, or SST39WF1602-70-4I-B3KE-T equivalent, key selection considerations include its 48-ball WFBGA (4 mm × 6 mm) package, JEDEC x16 flash command compatibility, SuperFlash technology-based endurance (100,000 cycles), and 100+ year data retention at industrial temperature range (–40°C to +85°C).
Technical Context
The SST39WF1602-70-4I-B3KE-T implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count and eliminating system-level de-rating. Its control logic supports standard JEDEC flash command sets-including Word-Program (28 µs typical), Sector-Erase (36 ms), Block-Erase (36 ms), and Chip-Erase (140 ms)-with toggle-bit (DQ6/DQ2) and data-polling (DQ7) status detection.
Hardware block protection is implemented via the WP# pin, which-when grounded-prevents program/erase on the top 32 KWord boot block (0F8000H–0FFFFFH). The RST# pin provides hardware reset to Read mode, while CFI Query (SST and general modes) and Security ID (128-bit factory + 128-bit user) support system-level identification and secure provisioning.

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), 48-pin TSOP; lacks Auto Low Power mode and Security ID; 100,000-cycle endurance same. | Requires level-shifting for 1.8 V systems; no hardware top-block protection-relies on software locks only. | Select when legacy 3 V infrastructure exists and security features are non-critical; not suitable for direct 1.8 V MCU interfaces. |
| S29GL032N90TFIR20 | 3.0 V supply, 48-ball BGA (6 × 8 mm); includes ECC and page-mode reads; higher 1 MByte density but slower 90 ns access. | Targeted at high-reliability telecom applications; larger footprint and incompatible pinout prevent PCB reuse. | Choose for mission-critical systems needing built-in ECC; avoid when board space, voltage, or timing budgets are constrained. |
Compared with MX29LV160ETTI-70G and S29GL032N90TFIR20, the SST39WF1602-70-4I-B3KE-T uniquely combines 1.65–1.95 V operation, 4 mm × 6 mm WFBGA packaging, top-block hardware protection, and integrated Security ID-making it optimal for next-generation compact, low-power, and secure embedded designs.

FAQ
What is the operating voltage range for the SST39WF1602-70-4I-B3KE-T?
The SST39WF1602-70-4I-B3KE-T operates from 1.65 V to 1.95 V for both read and write operations. This single-supply range eliminates the need for external voltage translators in 1.8 V systems and ensures compatibility with modern low-power microcontrollers. Operation outside this range-especially below 1.5 V-is inhibited by internal VDD detection circuitry to prevent inadvertent writes.
Does the SST39WF1602-70-4I-B3KE-T support hardware write protection?
Yes, the SST39WF1602-70-4I-B3KE-T includes dedicated hardware block protection via the WP# pin. When WP# is driven low, the top 32 KWord boot block (0F8000H–0FFFFFH) is locked against program and erase operations. If WP# is left floating, an internal pull-up holds it high, leaving the block unprotected-enabling full device flexibility during development.
How does the SST39WF1602-70-4I-B3KE-T indicate completion of a program or erase operation?
The SST39WF1602-70-4I-B3KE-T provides two real-time status detection methods: Data# Polling (DQ7) and Toggle Bits (DQ6/DQ2). During Word-Program, DQ7 returns complemented data until completion, then true data; DQ6 toggles continuously until the operation finishes. These mechanisms allow host software to poll asynchronously without fixed timeout delays, optimizing system efficiency.
What package type is used for the SST39WF1602-70-4I-B3KE-T?
The SST39WF1602-70-4I-B3KE-T uses a 48-ball WFBGA package measuring 4 mm × 6 mm with 0.5 mm ball pitch. This compact, RoHS-compliant package supports high-density PCB layouts and is distinct from the larger 48-ball TFBGA (6 mm × 8 mm) variant offered for the same part family-ensuring mechanical and thermal differentiation in design-in.
Is the SST39WF1602-70-4I-B3KE-T qualified for automotive applications?
The SST39WF1602-70-4I-B3KE-T is available in AEC-Q100-qualified versions, meeting stress test requirements for automotive use. While the base part number denotes industrial temperature grade (–40°C to +85°C), qualified variants undergo additional screening and lot-level validation-making them suitable for ADAS, body control modules, and infotainment boot memory where reliability under thermal cycling and vibration is critical.
