Product details
Overview
SST39VF200A-70-4C-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 100,000 program/erase cycles and >100 years data retention for embedded firmware storage in industrial control systems.
For engineers reviewing the SST39VF200A-70-4C-EKE datasheet, SST39VF200A-70-4C-EKE pinout, SST39VF200A-70-4C-EKE application, or SST39VF200A-70-4C-EKE equivalent, key selection criteria include its 2.7 V minimum operating voltage, uniform 2 KWord sector erase, SuperFlash® technology energy efficiency, and TSOP-48 package compatibility with legacy x16 memory sockets.
Technical Context
The SST39VF200A-70-4C-EKE implements SST's proprietary SuperFlash® split-gate cell architecture with thick-oxide tunneling injector, enabling fixed 14 µs word-program and 18 ms sector/block-erase times independent of wear level. Its command-set follows JEDEC-standard flash protocols including Software Data Protection (SDP) with six-byte erase sequences and three-byte program initiation.
It supports three detection methods for write completion: Data# Polling (DQ7), Toggle Bit (DQ6), and CFI Query mode entry via 5555H/98H sequence. Hardware protection includes noise/glitch immunity (<5 ns pulse rejection), VDD power-up/down detection (<1.5 V inhibit), and write-inhibit mode via OE#/CE#/WE# logic states.

FAQ
What is the maximum operating temperature range for the SST39VF200A-70-4C-EKE?
The SST39VF200A-70-4C-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 SST39VF200A-70-4C-EKE maintains full timing compliance and data retention guarantees across this full range.
Does the SST39VF200A-70-4C-EKE support Common Flash Interface (CFI) mode?
Yes, the SST39VF200A-70-4C-EKE supports CFI Query mode via the standard JEDEC entry sequence (write 98H to address 5555H after the 5555H/AAH → 2AAAH/55H preamble). Once entered, CFI data-including geometry, timing, and command set descriptors-is readable at defined offsets. This enables runtime auto-detection in bootloader code, and the SST39VF200A-70-4C-EKE implements full CFI compliance per publication 100.
How many erase sectors does the SST39VF200A-70-4C-EKE contain, and what is their size?
The SST39VF200A-70-4C-EKE contains 64 uniform erase sectors, each sized at 2 KWords (4 KB). This is derived from Table 7 in the DS25001A datasheet, where sector count = y + 1 = 63 + 1 = 64 and sector size = z × 256 B = 16 × 256 B = 4 KB. Sector erase is initiated using the 30H command with AMS–A11 address lines.
Is the SST39VF200A-70-4C-EKE pin-compatible with the SST39LF200A-70-4C-EKE?
Yes, the SST39VF200A-70-4C-EKE is pin-compatible with the SST39LF200A-70-4C-EKE in the same TSOP-48 package. Both share identical pin assignments, signal definitions, and JEDEC-standard x16 interface. The primary difference is supply voltage: SST39VF200A-70-4C-EKE operates down to 2.7 V, while SST39LF200A-70-4C-EKE requires 3.0–3.6 V. No PCB changes are needed for substitution if system VDD meets both specifications.
What write-protection mechanisms does the SST39VF200A-70-4C-EKE implement?
The SST39VF200A-70-4C-EKE implements dual-layer protection: hardware-level features (noise/glitch immunity for pulses <5 ns, VDD power-up/down detection below 1.5 V, and write-inhibit mode via OE#/CE#/WE# logic states) plus software-level protection via mandatory JEDEC-compliant Software Data Protection (SDP) sequences-three bytes for program, six bytes for erase. These mechanisms ensure robustness against unintended writes during power transitions or EMI events.
