Product details
Overview
SST39VF1601C-70-4I-EKE-T from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus (MPF+) memory IC with JEDEC-standard x16 interface, 70 ns read access time, and single 2.7–3.6V supply operation. It features bottom-boot block protection (00000H–01FFFH), 100,000-program/erase cycle endurance, and >100-year data retention - deployed in embedded firmware storage for industrial controllers and legacy BIOS modules.
For engineers reviewing the SST39VF1601C-70-4I-EKE-T datasheet, SST39VF1601C-70-4I-EKE-T pinout, SST39VF1601C-70-4I-EKE-T application, or SST39VF1601C-70-4I-EKE-T equivalent, this page delivers verified pin functions, boot-block architecture details, erase-suspend capability, RY/BY# status signaling, and hardware write-protection behavior - all confirmed for the exact TSOP-48 packaged variant.
Technical Context
The SST39VF1601C-70-4I-EKE-T implements SST's SuperFlash split-gate cell technology with thick-oxide tunneling injector, enabling fixed 7 µs word-program and 18 ms sector/block-erase times independent of wear level. Its command-set architecture requires six-byte sequences for sector/block/chip erase and supports JEDEC-standard CFI query mode via 555H/98H entry.
It integrates dual status detection: Data# Polling (DQ7) and Toggle Bit (DQ6/DQ2), plus open-drain RY/BY# output with external 10 kΩ pull-up. Hardware block protection is activated by grounding WP#, locking the bottom 8 KWord (00000H–01FFFH); RST# provides hardware reset to Read mode within TRP timing.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| VSS | Ground | Signal and power ground reference; two dedicated pins for noise isolation |
| NC | No Connection | Pins 2, 46, 47 - unconnected; must be left floating or tied to VSS per layout rules |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Pause sector/block erase to read/program other locations - critical for fail-safe firmware updates |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - eliminates need for software sleep management |
| Security ID Space | 128-bit factory ID + 128-word user-programmable space - supports device authentication and secure boot key storage |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1602C-70-4I-EKE-T | Top-boot architecture (FE000H–FFFFFH protected); identical timing, voltage, and command set | Used where bootloader resides in top memory region - incompatible pin-for-pin due to different boot-block address mapping | Select only if system firmware expects top-boot layout; not interchangeable without software modification |
| MX29LV160ETTI-70G | Same 16 Mbit x16, 70 ns, 2.7–3.6 V; supports CFI but lacks Security ID and erase-suspend | Lower-cost alternative for basic firmware storage where security and suspend capability are unnecessary | Valid for cost-sensitive consumer electronics; avoid in safety-critical or field-upgradable systems requiring suspend/resume |
Compared with SST39VF1602C-70-4I-EKE-T, the SST39VF1601C-70-4I-EKE-T provides bottom-boot protection essential for legacy x86 BIOS layouts, while MX29LV160ETTI-70G offers cost savings at the expense of security and real-time erase management - making SST39VF1601C-70-4I-EKE-T the only choice for certified medical or industrial firmware with suspend-enabled update protocols.

FAQ
What boot-block configuration does the SST39VF1601C-70-4I-EKE-T implement?
The SST39VF1601C-70-4I-EKE-T implements bottom-boot block protection, locking the lowest 8 KWord (00000H–01FFFH) when WP# is grounded. This matches legacy x86 BIOS memory maps where startup code resides at the lowest address. The SST39VF1601C-70-4I-EKE-T datasheet confirms this in Table 5-2 and Section 5.12, distinguishing it from the top-boot SST39VF1602C variant.
Does the SST39VF1601C-70-4I-EKE-T support erase-suspend functionality?
Yes, the SST39VF1601C-70-4I-EKE-T fully supports Erase-Suspend and Erase-Resume commands (B0H and 30H). This allows interruption of sector or block erase to read or program other memory regions - a critical feature for fail-safe firmware updates. The SST39VF1601C-70-4I-EKE-T implements this per Section 5.4 and Figure 8-21 of its official datasheet DS20005018B.
What is the purpose of the RY/BY# pin on the SST39VF1601C-70-4I-EKE-T?
The RY/BY# pin on the SST39VF1601C-70-4I-EKE-T is an open-drain ready/busy indicator that goes low during internal program or erase operations and high when complete. It requires an external 10–100 kΩ pull-up resistor. This signal enables hardware-driven wait-state management, eliminating polling overhead - a confirmed function documented in Section 5.7 and Table 4-1 of the SST39VF1601C-70-4I-EKE-T datasheet.
Can the SST39VF1601C-70-4I-EKE-T operate from a 3.3 V supply only?
Yes, the SST39VF1601C-70-4I-EKE-T operates across 2.7–3.6 V, making 3.3 V its nominal and most common supply voltage. All specified timing (70 ns read, 7 µs program) and current values (9 mA active, 3 µA standby) are guaranteed within this range. The SST39VF1601C-70-4I-EKE-T is explicitly rated for 3.3 V systems in Section 1.0 and Table 4-1 of DS20005018B.
How is hardware write protection enabled on the SST39VF1601C-70-4I-EKE-T?
Hardware write protection on the SST39VF1601C-70-4I-EKE-T is enabled by pulling the WP# pin low, which locks the bottom 8 KWord boot block (00000H–01FFFH) against program and erase operations. If WP# is left floating, an internal pull-up holds it high, disabling protection. This behavior is defined in Section 5.12 and Table 4-1 of the SST39VF1601C-70-4I-EKE-T datasheet.
