Product details
Overview
SST39VF3201-70-4C-EKE-T from Microchip Technology is a 32 Mbit (2M × 16) CMOS Multi-Purpose Flash Plus memory IC with x16 asynchronous interface, 70 ns read access time, single 2.7–3.6 V supply operation, and bottom 32 KWord hardware block protection. It implements SuperFlash technology for high reliability in embedded firmware storage applications requiring in-system reprogrammability.
For engineers reviewing the SST39VF3201-70-4C-EKE-T datasheet, SST39VF3201-70-4C-EKE-T pinout, SST39VF3201-70-4C-EKE-T application, or SST39VF3201-70-4C-EKE-T equivalent, this page delivers verified technical context, JEDEC-compliant pin mapping, sector/block/erase timing, hardware reset (RST#), write protect (WP#), and Security-ID support - all confirmed for the exact TSOP-48 packaged variant.
Technical Context
This device uses SST's proprietary SuperFlash split-gate cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count and eliminating system-level de-rating. It supports JEDEC-standard command sets including Software Data Protection (SDP), CFI Query, and Security ID programming.
Operation modes include Read, Word-Program (7 µs typical), Sector-Erase (18 ms), Block-Erase (18 ms), Chip-Erase (40 ms), and Erase-Suspend/Resume. Status detection uses DQ6 toggle bit and DQ7 data polling, with Auto Low Power mode reducing active current to 3 µA after valid read access.

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF3201B-70-4C-EKE | Same density, speed, and package; updated revision with enhanced ESD robustness and tighter AC timing specs | Recommended for new designs per Microchip notice; identical pinout and command set | Select when designing new products requiring full manufacturer support lifecycle |

The SST39VF3201-70-4C-EKE-T belongs to the Multi-Purpose Flash Plus (MPF+) product line, designed specifically for embedded systems requiring reliable, low-voltage, in-system programmable nonvolatile storage with hardware security and JEDEC interoperability.
FAQ
What is the memory organization of the SST39VF3201-70-4C-EKE-T?
The SST39VF3201-70-4C-EKE-T is organized as 2M × 16, providing 32 Mbit (4 MB) of addressable storage space. Its 20-bit address bus (A0–A19) and 16-bit data bus (DQ0–DQ15) conform to JEDEC-standard x16 flash pinouts, enabling drop-in compatibility with other industry-standard 32 Mbit x16 devices in TSOP-48 packages.
Does the SST39VF3201-70-4C-EKE-T support hardware write protection?
Yes, the SST39VF3201-70-4C-EKE-T supports bottom 32 KWord hardware block protection via the WP# pin. When WP# is driven low, program and erase operations on addresses 000000H–007FFFH are inhibited - protecting the boot loader region. This is distinct from the top-block protection used in SST39VF3202 variants.
What is the purpose of the RST# pin on the SST39VF3201-70-4C-EKE-T?
The RST# pin on the SST39VF3201-70-4C-EKE-T provides hardware-initiated recovery: holding RST# low for ≥ TRP aborts any in-progress erase or program operation and forces the device back into read mode. After release, a minimum TRHR delay is required before valid reads resume - ensuring state consistency after power faults or watchdog resets.
Can the SST39VF3201-70-4C-EKE-T be used with a 3.3 V microcontroller interface?
Yes, the SST39VF3201-70-4C-EKE-T operates natively from 2.7–3.6 V and features CMOS I/O compatibility. Its VDD range fully overlaps with standard 3.3 V logic levels, and no external level shifters are needed when interfacing with 3.3 V microcontrollers, FPGAs, or SoCs - simplifying board design and reducing BOM cost.
Is the SST39VF3201-70-4C-EKE-T still recommended for new designs?
No - Microchip explicitly marks the SST39VF3201-70-4C-EKE-T as "Not Recommended for New Designs" in DS25028A. The SST39VF3201B-70-4C-EKE is the designated replacement, offering identical functionality with improved manufacturing yield and extended qualification. Legacy designs may continue using SST39VF3201-70-4C-EKE-T, but new projects should adopt the 'B' revision.
