Product details
Overview
SST39WF1602-90-4C-B3KE 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 90 ns read access time, top 32 KWord hardware block protection, and SuperFlash technology for enhanced endurance (100,000 cycles) and data retention (>100 years). It serves as nonvolatile program/data storage in embedded controllers and firmware update modules.
For engineers reviewing the SST39WF1602-90-4C-B3KE datasheet, SST39WF1602-90-4C-B3KE pinout, SST39WF1602-90-4C-B3KE application, or SST39WF1602-90-4C-B3KE equivalent, this page delivers verified specifications, JEDEC-compliant x16 interface details, TFBGA/WFBGA package mapping, and real-world flash replacement guidance for industrial firmware systems.
Technical Context
The SST39WF1602-90-4C-B3KE implements a split-gate SuperFlash cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It supports standard asynchronous x16 bus operation with CE#, OE#, and WE# control signals, latched address/data timing, and Auto Low Power mode reducing active read current to 5 µA after valid access.
It integrates JEDEC-standard command sets for Word-Program (28 µs typical), Sector-Erase (36 ms), Block-Erase (36 ms), Chip-Erase (140 ms), and Erase-Suspend/Resume functions. Hardware block protection is activated via WP# grounding to lock the top 32 KWord boot block (0F8000H–0FFFFFH), while RST# provides hardware reset to read mode.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160ETTI-90G | 3.0 V supply (2.7–3.6 V), 90 ns access, bottom-boot configuration, no Auto Low Power mode | Lacks 1.8 V compatibility and low-power read mode; requires voltage translation in 1.8 V systems | Select only if existing 3 V design uses MX29LV family and board layout cannot accommodate voltage regulator change. |
| S29GL032N90TFI010 | 3.0 V supply, 90 ns access, 32 Mbit density, mirror-bit architecture, no hardware WP# block lock | Higher density but incompatible voltage range; relies on software protection instead of pin-level boot block lock | Choose when migrating to larger firmware images and system already supports 3 V flash; verify bootloader rework for mirror-bit addressing. |
Compared with MX29LV160ETTI-90G and S29GL032N90TFI010, the SST39WF1602-90-4C-B3KE uniquely delivers 1.8 V operation, top-boot hardware protection, and Auto Low Power mode-critical for battery-backed or energy-constrained embedded systems where voltage headroom and power budget are tightly constrained.

FAQ
What is the exact memory organization of the SST39WF1602-90-4C-B3KE?
The SST39WF1602-90-4C-B3KE is organized as 1,048,576 words × 16 bits (1M × 16), totaling 16 Mbit. It features uniform 2 KWord sectors (512 total) and 32 KWord blocks (32 total), with top 32 KWord (0F8000H–0FFFFFH) designated as hardware-protected boot block. This structure is confirmed in Table 2 and Figure 1 of the official datasheet.
Does the SST39WF1602-90-4C-B3KE require an external VPP voltage for programming?
No, the SST39WF1602-90-4C-B3KE does not require external VPP. It generates internal high-voltage programming pulses using its 1.65–1.95 V supply, as stated in the "Automatic Write Timing" feature and confirmed in Table 8 (VPP min/max = 0000H). This eliminates need for charge pumps or auxiliary power rails.
How does hardware block protection work on the SST39WF1602-90-4C-B3KE?
Hardware block protection on the SST39WF1602-90-4C-B3KE is enabled by pulling WP# low, which locks the top 32 KWord boot block (0F8000H–0FFFFFH) against program and erase operations. If WP# floats, an internal pull-up keeps it high, leaving the block unprotected. This behavior is explicitly defined in the "Hardware Block Protection" section and Table 2.
What is the purpose of the RST# pin on the SST39WF1602-90-4C-B3KE?
The RST# pin on the SST39WF1602-90-4C-B3KE provides hardware-initiated abort of in-progress erase or program operations and forces immediate return to read mode. When held low for ≥TRP, it terminates internal cycles; after release, a minimum TRHR delay is required before valid reads. This is documented in the "Hardware Reset (RST#)" section and Figure 16.
Can the SST39WF1602-90-4C-B3KE be used in systems requiring Common Flash Interface (CFI) support?
Yes, the SST39WF1602-90-4C-B3KE fully supports CFI through both SST-specific and general CFI Query modes, enabling automatic detection of geometry, timing, and command set by host firmware. CFI entry commands (98H), query address ranges (Tables 7–9), and exit sequences are all specified in the datasheet.
