Product details
Overview
SST39VF1601-70-4I-EKE-T from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with single-supply 2.7–3.6 V operation, 70 ns read access time, bottom 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface. It serves as nonvolatile program/data storage in embedded controllers, BIOS firmware modules, and industrial HMI systems requiring field-upgradable code.
For engineers reviewing the SST39VF1601-70-4I-EKE-T datasheet, SST39VF1601-70-4I-EKE-T pinout, SST39VF1601-70-4I-EKE-T application, or SST39VF1601-70-4I-EKE-T equivalent, this page delivers verified technical context, JEDEC-compliant pin mapping, real-world use scenarios, and two validated alternative flash parts for legacy design continuity and migration planning.
Technical Context
The SST39VF1601-70-4I-EKE-T implements SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed 7 µs word-program and 18 ms sector/block-erase times independent of endurance cycles. Its command-set architecture supports Software Data Protection (SDP) via six-byte sequences for erase and three-byte sequences for program, plus Erase-Suspend/Resume using B0H/30H commands.
It features dual status detection-Data# Polling (DQ7) and Toggle Bits (DQ6/DQ2)-for end-of-write verification, hardware WP#-controlled bottom-boot-block protection (000000H–007FFFH), and RST#-driven hardware reset to Read mode. The device conforms to JEDEC standard x16 flash pinouts and supports CFI Query mode for automated system identification.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C-70-4I-EKE | Same density, speed, and package; updated revision with enhanced ESD robustness and tighter tACC spec (65 ns typ) | Recommended for new designs per Microchip; identical pinout and command set; drop-in replacement | Select for new production to ensure long-term availability and improved manufacturing yield |
| MX29LV160DTTI-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V; uses different command set (no Erase-Suspend); lacks Security ID and CFI | Requires firmware driver modification; no suspend/resume support limits real-time update capability | Choose only if legacy system compatibility mandates Macronix command compatibility and CFI is unused |
Compared with SST39VF1601C-70-4I-EKE, the SST39VF1601-70-4I-EKE-T offers identical functionality but is Not Recommended for New Designs; compared with MX29LV160DTTI-70G, it delivers superior real-time update flexibility via Erase-Suspend and stronger security via 256-bit ID, at the cost of vendor-specific command handling.

FAQ
What is the memory organization and density of the SST39VF1601-70-4I-EKE-T?
The SST39VF1601-70-4I-EKE-T is organized as 1M × 16 bits, delivering 16 Mbit (2 MByte) of nonvolatile flash memory. This structure supports x16 data bus interfacing and maps directly to common 16-bit microprocessor address spaces. Its density is fixed and confirmed in the datasheet DS25028A, Table 9, where Device Size = 2²¹ bytes (21H = 21 decimal). The SST39VF1601-70-4I-EKE-T does not support x8 or x32 configurations.
Does the SST39VF1601-70-4I-EKE-T support hardware write protection, and how is it implemented?
Yes, the SST39VF1601-70-4I-EKE-T implements hardware block protection for the bottom 32 KWord (128 KB) region (000000H–007FFFH) via the WP# pin. When WP# is driven low, Program and Erase operations on that protected boot block are inhibited. If WP# is left floating, an internal pull-up holds it high, disabling protection. This behavior is explicitly defined in the datasheet DS25028A, Section "Hardware Block Protection" and Table 3.
What are the supported erase capabilities of the SST39VF1601-70-4I-EKE-T?
The SST39VF1601-70-4I-EKE-T supports three erase modes: Sector-Erase (2 KWord uniform sectors), Block-Erase (32 KWord uniform blocks), and Chip-Erase (full array). Typical erase times are 18 ms for sector/block and 40 ms for chip erase. All modes use JEDEC-standard command sequences and support Data# Polling (DQ7) and Toggle Bit (DQ6) status detection. These capabilities are documented in DS25028A Sections 6 and Table 6.
Is the SST39VF1601-70-4I-EKE-T pin-compatible with other members of the SST39VF160x family?
Yes, the SST39VF1601-70-4I-EKE-T shares identical pinout and electrical characteristics with SST39VF1602-70-4I-EKE-T in the 48-lead TSOP package, differing only in block protection location (bottom vs. top) and boot block address range. Both conform to JEDEC-standard x16 flash pinouts. This compatibility is confirmed in DS25028A Figures 2 and Table 1, and applies strictly within the same package type.
What is the purpose and implementation of the Security ID feature in the SST39VF1601-70-4I-EKE-T?
The SST39VF1601-70-4I-EKE-T includes a 256-bit Security ID space: 128 bits factory-programmed by SST and 128 bits user-programmable. It supports secure boot authentication and device binding. Programming uses the Security ID Word-Program command (A5H), with end-of-write detected via Toggle Bits (not Data# Polling). Once locked via User Sec ID Program Lock-Out (85H), the user segment becomes immutable. Details are in DS25028A Section "Security ID".
