Product details
Overview
SST39VF800A-70-4C-EKE-T from Microchip Technology is an 8 Mbit (512K × 16) CMOS Multi-Purpose Flash memory IC with 2.7–3.6 V single-supply operation, 70 ns read access time, JEDEC-standard x16 asynchronous interface, and SuperFlash® split-gate technology enabling 100,000 program/erase cycles and >100 years data retention. It serves as nonvolatile code/data storage in embedded microcontroller systems requiring field-upgradable firmware.
For engineers reviewing the SST39VF800A-70-4C-EKE-T datasheet, SST39VF800A-70-4C-EKE-T pinout, SST39VF800A-70-4C-EKE-T application, or SST39VF800A-70-4C-EKE-T equivalent, key selection criteria include its 48-pin TSOP package, uniform 2 KWord sector / 32 KWord block erase architecture, hardware/software write protection, toggle-bit and data# polling status detection, and compatibility with standard x16 memory bus timing.
Technical Context
The SST39VF800A-70-4C-EKE-T implements a JEDEC-compliant x16 asynchronous parallel interface with CE#, OE#, and WE# control lines, supporting Word-Program, Sector-Erase, Block-Erase, and Chip-Erase operations via six-byte command sequences. Its SuperFlash® technology uses a split-gate cell with thick-oxide tunneling injector for fixed, cycle-independent erase/program times.
It features latched address and data inputs, tri-state outputs controlled by CE# and OE#, internal VPP generation, and dual end-of-write detection (DQ6 toggle bit and DQ7 data# polling). The device supports CFI Query mode and Software Product ID mode for automated system identification and configuration.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF800A-70-4C-B3K | Same die, 48-ball TFBGA (6 mm × 8 mm) package instead of TSOP; identical timing, voltage, and command set | Targeted at space-constrained PCB layouts where footprint area is prioritized over manual rework accessibility | Select for high-density routing or automated assembly; requires BGA reflow profile and X-ray inspection |
| MX29LV800CTTI-70G | 8 Mbit x16 flash with 70 ns access, but uses different command set (AMD/Fujitsu), no CFI support, and 10,000-cycle endurance | Suitable for cost-sensitive consumer electronics where firmware rarely updates and qualification rigor is lower | Select only if existing design already uses MX29LV family; not drop-in due to command incompatibility and reduced reliability |

FAQ
What is the memory organization and density of the SST39VF800A-70-4C-EKE-T?
The SST39VF800A-70-4C-EKE-T is organized as 512K words × 16 bits, delivering 8 Mbit (1 MByte) of nonvolatile storage. This x16 configuration matches standard microprocessor data bus widths and is explicitly confirmed in the DS25001A datasheet Table 9 for the SST39VF800A variant. The SST39VF800A-70-4C-EKE-T uses this full capacity with no bank switching or partial addressing required.
Does the SST39VF800A-70-4C-EKE-T support both sector and block erase modes?
Yes, the SST39VF800A-70-4C-EKE-T supports both uniform 2 KWord sector erase (256 sectors) and uniform 32 KWord block erase (16 blocks), as defined in Tables 7–9 of the DS25001A datasheet. Sector erase enables fine-grained updates (e.g., patching a single function), while block erase provides faster bulk erasure (e.g., loading new firmware images), both initiated via JEDEC-standard six-byte command sequences.
What write protection mechanisms does the SST39VF800A-70-4C-EKE-T implement?
The SST39VF800A-70-4C-EKE-T implements dual-layer protection: hardware features (noise/glitch filtering on WE#/CE#, VDD power-up/down detection, and write-inhibit mode) plus mandatory software data protection (SDP) requiring three-byte unlock sequences for programming and six-byte sequences for erasing. These are documented in Sections 8–9 of DS25001A and apply identically to the SST39VF800A-70-4C-EKE-T.
Is the SST39VF800A-70-4C-EKE-T compatible with standard JEDEC x16 flash interfaces?
Yes, the SST39VF800A-70-4C-EKE-T conforms fully to JEDEC standard pinouts and command sets for x16 memories, including CE#, OE#, WE#, and DQ0–DQ15 signal definitions and timing. Its pin assignments match Figure 2 (TSOP) in DS25001A, and its command sequences (e.g., Word-Program, Sector-Erase) align with JEDEC publication 100, ensuring interoperability with existing x16 memory controllers.
What is the guaranteed data retention and endurance specification for the SST39VF800A-70-4C-EKE-T?
The SST39VF800A-70-4C-EKE-T is rated for greater than 100 years of data retention and 100,000 program/erase cycles under specified operating conditions (2.7–3.6 V, 0°C to +70°C), as stated in the Features section and Product Description of DS25001A. These values are typical and guaranteed across the commercial temperature range for the SST39VF800A-70-4C-EKE-T.
