Product details
Overview
SST39VF200A-70-4I-EKE from Microchip Technology is a 2 Mbit (128K × 16) CMOS Multi-Purpose Flash memory IC with x16 asynchronous interface, 70 ns read access time, 2.7–3.6 V single-supply operation, and JEDEC-standard pinout. It delivers sector/block/whole-chip erase capability, 100,000 program/erase cycles endurance, and >100 years data retention for embedded firmware storage in industrial control systems.
For engineers reviewing the SST39VF200A-70-4I-EKE datasheet, SST39VF200A-70-4I-EKE pinout, SST39VF200A-70-4I-EKE application, or SST39VF200A-70-4I-EKE equivalent, key selection criteria include its 2.7 V minimum VDD support, uniform 2 KWord sector architecture, toggle-bit/data# polling status detection, and compatibility with standard microprocessor bus timing.
Technical Context
The SST39VF200A-70-4I-EKE implements SST's proprietary SuperFlash technology with split-gate cell design and thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. Its command-set architecture follows JEDEC-standard flash protocols, supporting software data protection via six-byte sequences for erase and three-byte sequences for word-program.
It operates in standard asynchronous mode with CE#, OE#, and WE# control signals, latched address/data buses, and tri-state outputs. The device supports CFI query mode for runtime identification and provides hardware-level write inhibition during power-up/down via VDD monitoring and noise filtering on control pins.

FAQ
What is the maximum operating temperature range for the SST39VF200A-70-4I-EKE?
The SST39VF200A-70-4I-EKE is rated for industrial temperature operation from –40°C to +85°C. This specification is confirmed in the "Operating Range" table of the DS25001A datasheet and applies to all functional operations including read, program, and erase. The "I" suffix in the part number explicitly denotes industrial grade, distinguishing it from commercial-grade variants like the SST39VF200A-70-4C-EKE.
Does the SST39VF200A-70-4I-EKE require an external VPP voltage for programming?
No, the SST39VF200A-70-4I-EKE does not require an external VPP voltage. It uses internal charge pump circuitry to generate the high voltage needed for erase and program operations from the single 2.7–3.6 V VDD supply. This is explicitly stated in the "Automatic Write Timing" feature list and confirmed in Table 6 of the DS25001A datasheet, where VPP min/max values are listed as 0000H, indicating no VPP pin or external voltage requirement.
How many address lines does the SST39VF200A-70-4I-EKE use for full memory addressing?
The SST39VF200A-70-4I-EKE uses 17 address lines (A0–A16) to access its full 128K × 16 organization. A0–A15 select individual 16-bit words within a 64 KB block, while A16 selects between the lower and upper 64 KB halves of the 128 KB address space. This mapping is defined in Table 1 ("Pin Description") and verified in Figure 2 (TSOP pinout), where A16 is assigned to pin 26.
What erase granularities are supported by the SST39VF200A-70-4I-EKE?
The SST39VF200A-70-4I-EKE supports three erase modes: sector-erase (2 KWord = 4 KB), block-erase (32 KWord = 64 KB), and chip-erase (entire 128K × 16 array). Sector and block sizes are uniform across the memory array, as specified in the "Sector-Erase Capability" and "Block-Erase Capability" features and detailed in Table 7 of the DS25001A datasheet.
Is the SST39VF200A-70-4I-EKE compatible with standard JEDEC flash command sets?
Yes, the SST39VF200A-70-4I-EKE conforms to JEDEC standard pinouts and command sets for x16 flash memories. It implements the JEDEC-approved Software Data Protection scheme and supports standard command sequences for word-program, sector-erase, block-erase, and chip-erase as documented in Table 4 of DS25001A. Its CFI implementation also complies with JEDEC publication 100 for runtime identification.
