Product details
Overview
SST39VF1602-70-4C-EKE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with 70 ns read access time, single 2.7–3.6 V supply operation, and top 32 KWord hardware block protection. It supports sector/block/chip erase, erase-suspend/resume, and Security-ID functionality for embedded firmware storage in industrial control and legacy communication systems.
For engineers reviewing the SST39VF1602-70-4C-EKE datasheet, SST39VF1602-70-4C-EKE pinout, SST39VF1602-70-4C-EKE application, or SST39VF1602-70-4C-EKE equivalent, key selection considerations include JEDEC x16 flash compatibility, TSOP-48 package footprint, top-boot block protection address range (0F8000H–0FFFFFH), and SuperFlash endurance (100,000 cycles).
Technical Context
The SST39VF1602-70-4C-EKE implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. It uses standard asynchronous x16 interface timing with CE#, OE#, and WE# control signals and latched address/data buses.
Hardware write protection is implemented via the WP# pin, which disables program/erase on the top 32 KWord boot block when grounded. The RST# pin provides hardware reset to Read mode, and status detection relies on DQ6 toggle bit and DQ7 data# polling-both validated after sixth WE# pulse for erase operations.
Key Specifications

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 32 KWord block protection; same density/timing; newer revision with improved ESD rating | Requires PCB layout change due to inverted boot block address mapping (000000H–007FFFH vs. 0F8000H–0FFFFFH) | Select when redesigning for enhanced reliability and bottom-boot architecture compatibility |
| MX29LV160DTTC-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V; supports CFI but lacks Security-ID and erase-suspend | No hardware boot block protection; requires software-managed write lock; no suspend capability for real-time systems | Select for cost-sensitive designs where security and background erase are not required |
Compared with SST39VF1601C and MX29LV160DTTC-70G, the SST39VF1602-70-4C-EKE uniquely combines top-boot hardware protection, erase-suspend, and 256-bit Security-ID in a JEDEC-compatible TSOP-48 package - making it irreplaceable in legacy systems requiring guaranteed bootloader integrity and real-time firmware maintenance.

FAQ
What is the boot block protection scheme for SST39VF1602-70-4C-EKE?
The SST39VF1602-70-4C-EKE implements top 32 KWord hardware block protection. When WP# is grounded, program and erase operations are disabled on the address range 0F8000H–0FFFFFH. This protects the bootloader region from accidental corruption during firmware updates. The SST39VF1602-70-4C-EKE datasheet confirms this behavior is distinct from SST39VF1601/3201, which protects the bottom block instead.
Does SST39VF1602-70-4C-EKE support erase-suspend functionality?
Yes, the SST39VF1602-70-4C-EKE supports Erase-Suspend and Erase-Resume commands (B0H and 30H). This allows the host system to temporarily halt an ongoing sector or block erase, read data from unprotected locations, or program other sectors - then resume the suspended erase. This capability is essential for real-time systems where uninterrupted data access is required during background flash maintenance. The SST39VF1602-70-4C-EKE implements this using DQ2 and DQ6 status bits.
What package type is used for SST39VF1602-70-4C-EKE?
The SST39VF1602-70-4C-EKE is supplied in a 48-lead TSOP (Thin Small Outline Package) measuring 12 mm × 20 mm, with standard JEDEC x16 flash pinout. It is RoHS compliant and pin-compatible with other members of the SST39VF160x/320x family in the same package variant. The "EKE" suffix explicitly denotes the TSOP-48 packaging, as confirmed in Microchip's official documentation DS25028A.
How does SST39VF1602-70-4C-EKE indicate completion of a program or erase operation?
The SST39VF1602-70-4C-EKE provides two software-detectable status mechanisms: Data# Polling (DQ7) and Toggle Bit (DQ6). During program, DQ7 returns complemented data until completion, then true data. During erase, DQ7 reads '0' until done, then '1'. DQ6 toggles between 0 and 1 during operation and stops when complete. Both methods are validated after the fourth WE# pulse for program and sixth for erase - a core timing requirement defined in the SST39VF1602-70-4C-EKE specification.
Is SST39VF1602-70-4C-EKE recommended for new designs?
No - Microchip explicitly marks SST39VF1602-70-4C-EKE as "Not Recommended for New Designs" in DS25028A. The datasheet recommends migrating to SST39VF1601C for new projects, citing improved reliability and updated manufacturing process. However, SST39VF1602-70-4C-EKE remains fully supported for existing designs, with guaranteed supply continuity and full backward compatibility in legacy systems where top-boot protection is architecturally required.
