Product details
Overview
SST39VF1602-70-4C-EKE-T from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with JEDEC-standard x16 asynchronous interface, 70 ns read access time, hardware top-block protection, and single 2.7–3.6V supply operation. It supports sector/block/chip erase, erase-suspend/resume, and Security ID for embedded firmware storage in industrial control panels and legacy communication modules.
For engineers reviewing the SST39VF1602-70-4C-EKE-T datasheet, SST39VF1602-70-4C-EKE-T pinout, SST39VF1602-70-4C-EKE-T application, or SST39VF1602-70-4C-EKE-T equivalent, this page delivers verified flash timing, block-protection behavior, TSOP-48 pin mapping, endurance (100,000 cycles), and JEDEC-compliant command set details required for firmware update architecture and BOM continuity planning.
Technical Context
The SST39VF1602-70-4C-EKE-T implements SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its architecture supports uniform 2 KWord sectors (512 total) and 32 KWord blocks (32 total), with top-boot block protection covering address range 0F8000H–0FFFFFH.
It uses standard microprocessor bus timing with CE#/OE#/WE# control, latched address/data, and dual status detection (DQ7 Data# Polling and DQ6 Toggle Bit). The device enters Auto Low Power mode after valid read access, reducing active current from 9 mA to 3 µA without access penalty.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C | Bottom-block protection (000000H–007FFFH); same density/timing; newer revision with improved ESD rating | Requires firmware partitioning change to place bootloader in bottom block instead of top | Select when redesigning for new production and bottom-boot architecture is acceptable |
| MX29LV160CTTI-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V, but uses different command set and lacks Security ID and erase-suspend | Compatible pinout but requires driver rewrite; no hardware suspend capability for concurrent operations | Select only if CFI compatibility and suspend/resume are not required and legacy driver reuse is critical |
Compared with SST39VF1601C and MX29LV160CTTI-70G, the SST39VF1602-70-4C-EKE-T uniquely provides top-boot hardware protection and erase-suspend functionality-critical for systems requiring live firmware validation during update without halting host operation.

FAQ
What is the memory organization and density of the SST39VF1602-70-4C-EKE-T?
The SST39VF1602-70-4C-EKE-T is organized as 1M × 16, delivering 16 Mbit (2 MB) of nonvolatile storage. This configuration supports direct connection to 16-bit microcontrollers and DSPs without data multiplexing. Its address space spans 000000H to 0FFFFFH, with top-boot block protection covering 0F8000H–0FFFFFH. The SST39VF1602-70-4C-EKE-T uses SuperFlash technology to achieve consistent performance across its full endurance rating.
Does the SST39VF1602-70-4C-EKE-T support hardware write protection, and how is it configured?
Yes, the SST39VF1602-70-4C-EKE-T features hardware top-block protection activated by grounding the WP# pin, which locks the top 32 KWord (0F8000H–0FFFFFH) against program and erase operations. When WP# is left floating, an internal pull-up holds it high, disabling protection. This mechanism safeguards bootloader code from accidental overwrite during field firmware updates. The SST39VF1602-70-4C-EKE-T does not support bottom-block protection - that function is reserved for the SST39VF1601 variant.
What are the supported erase modes and their typical execution times for the SST39VF1602-70-4C-EKE-T?
The SST39VF1602-70-4C-EKE-T supports sector-erase (2 KWord), block-erase (32 KWord), and chip-erase modes, all with typical times of 18 ms, 18 ms, and 40 ms respectively. Erase operations use JEDEC-standard six-byte command sequences initiated at address 5555H. Status completion is verified via DQ7 Data# Polling or DQ6 Toggle Bit. The SST39VF1602-70-4C-EKE-T also supports Erase-Suspend to temporarily halt an ongoing erase and read/program other regions.
How does the SST39VF1602-70-4C-EKE-T handle power management during read operations?
The SST39VF1602-70-4C-EKE-T implements Auto Low Power mode: after a valid read access, it automatically transitions from 9 mA active current to 3 µA standby current without access time penalty. The device exits this mode on any address or control signal transition. This feature significantly reduces average power in systems with intermittent read patterns, such as polling-based diagnostics. The SST39VF1602-70-4C-EKE-T maintains full JEDEC compatibility throughout all power states.
Is the SST39VF1602-70-4C-EKE-T pin-compatible with other devices in the SST39VF160x family?
Yes, the SST39VF1602-70-4C-EKE-T shares identical 48-lead TSOP pinout and electrical interface with SST39VF1601, SST39VF3201, and SST39VF3202 variants. All use JEDEC-standard x16 asynchronous flash pin assignments, including CE#, OE#, WE#, WP#, and RST#. However, functional differences exist: SST39VF1602-70-4C-EKE-T implements top-block protection, while SST39VF1601 uses bottom-block protection. The SST39VF1602-70-4C-EKE-T requires correct address decoding for its top-boot region (0F8000H–0FFFFFH).
