Product details
Overview
SST39VF1601C-70-4I-B3KE-T from Silicon Storage Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus memory IC with bottom-boot block protection, 70 ns read access time, 2.7–3.6 V single-supply operation, and JEDEC-standard x16 asynchronous interface. It delivers 100,000 program/erase cycles and >100 years data retention for embedded firmware storage in industrial controllers and legacy system BIOS.
For engineers reviewing the SST39VF1601C-70-4I-B3KE-T datasheet, SST39VF1601C-70-4I-B3KE-T pinout, SST39VF1601C-70-4I-B3KE-T application, or SST39VF1601C-70-4I-B3KE-T equivalent, this page provides verified package mapping (48-ball WFBGA), hardware block-protection behavior (bottom 8 KWord), erase-suspend capability, RY/BY# status signaling, and sector/block/chip-erase timing values confirmed in the official S71380-04-000 datasheet.
Technical Context
The SST39VF1601C-70-4I-B3KE-T implements SuperFlash split-gate technology with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count-unlike conventional flash where timing degrades over endurance life. Its command set follows JEDEC-standard pinouts and software protocols including CFI Query, Security ID, and Software Data Protection.
It supports three erase granularities: uniform 2 KWord sectors, flexible blocks (thirty-one 32 KWord, one 16 KWord, two 4 KWord, one 8 KWord), and full-chip erase-all initiated via six-byte command sequences. Hardware write protection is implemented via WP# pin tied low to lock the bottom 8 KWord boot block (00000H–01FFFH), while RST# enables hardware reset to read mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words): sufficient for full BIOS/firmware images in space-constrained embedded systems. |
| Read Access Time | 70 ns: enables direct execution from flash (XIP) in microcontroller-based systems without wait states at moderate clock speeds. |
| Supply Voltage | 2.7–3.6 V: compatible with 3.3 V logic rails and tolerant of brown-out conditions down to 2.7 V during program/erase. |
| Endurance | 100,000 program/erase cycles: supports field-updatable firmware with multi-year service life under typical update frequency. |
| Data Retention | >100 years: ensures nonvolatile storage integrity across product lifecycle without refresh or backup power. |
| Erase Times | Sector/Block: 18 ms typ., Chip: 40 ms typ.-predictable timing simplifies real-time OS task scheduling during firmware updates. |
| Power Consumption | Active: 9 mA typ. @ 5 MHz; Standby/Auto Low Power: 3 µA typ.-reduces quiescent current in always-on control modules. |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, bottom-side thermal pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 20-bit address bus; A19–A11 select block during Block-Erase, A11–A0 select sector during Sector-Erase. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; tri-stated when CE# or OE# high; latched on rising edge of WE#/CE# during writes. |
| CE# | Chip Enable | Active-low device selection; asserts internal logic only when low-critical for multi-device memory decoding. |
| OE# | Output Enable | Active-low output gating; controls DQ bus drive without affecting internal state-enables shared-bus arbitration. |
| WE# | Write Enable | Controls write timing; falling edge latches address, rising edge latches data-synchronizes command sequence execution. |
| WP# | Write Protect | Hardware lock for bottom 8 KWord boot block (00000H–01FFFH); grounded = protected, floating = unprotected (internal pull-up). |
| RST# | Reset | Hardware abort of in-progress erase/program; forces return to Read mode within TRP (min. 100 ns pulse width required). |
| RY/BY# | Ready/Busy# | Open-drain status indicator; pulled low during erase/program-supports wired-OR monitoring across multiple flash devices. |
| VDD | Power Supply | 2.7–3.6 V core supply; powers all internal logic and charge pumps-no external VPP required due to on-chip generation. |
| VSS | Ground | Reference for all I/O and internal circuitry; requires low-impedance connection to minimize noise coupling during high-speed reads. |
| NC | No Connection | Unbonded pins (e.g., ball E1, H1 in WFBGA layout)-must remain unconnected per datasheet Figure 4. |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows read access to non-suspended sectors during active erase-enables real-time diagnostics or UI responsiveness during firmware update. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid read access-eliminates need for external power-gating logic in battery-backed systems. |
| Security ID Space | 128-bit factory-programmed ID + 128-word user-programmable segment-supports secure boot authentication and device-specific configuration binding. |
| Hardware Block Protection | Bottom 8 KWord (00000H–01FFFH) locked when WP# = low-prevents accidental corruption of boot code during field firmware upgrades. |
| End-of-Write Detection | Triple-method status: Toggle Bit (DQ6), Data# Polling (DQ7), and RY/BY#-provides software/hardware flexibility for timeout-free write completion polling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160DBTI-70G | 16 Mbit x16, 70 ns, bottom-boot, 2.7–3.6 V-but uses different command set (non-JEDEC standard) and lacks Erase-Suspend. | Requires firmware driver rewrite; no suspend/resume capability limits real-time system responsiveness during updates. | Select only if existing codebase already supports Macronix command protocol and suspend functionality is unnecessary. |
| EN29LV160AT-70TP | 16 Mbit x16, 70 ns, top-boot (FE000H–FFFFFH), same voltage range-but no Security ID feature and 50,000-cycle endurance rating. | Top-boot architecture incompatible with SST39VF1601C's bottom-boot memory map; lower endurance reduces field update margin. | Acceptable only for cost-sensitive designs where boot block location is flexible and update frequency is low. |
Compared with MX29LV160DBTI-70G and EN29LV160AT-70TP, the SST39VF1601C-70-4I-B3KE-T offers JEDEC-standard command compatibility, hardware-supported erase-suspend, and higher endurance-making it preferable for systems requiring firmware update robustness and cross-vendor design portability.

FAQ
What is the boot block configuration of the SST39VF1601C-70-4I-B3KE-T?
The SST39VF1601C-70-4I-B3KE-T implements bottom-boot architecture, protecting the lowest 8 KWord (00000H–01FFFH) as the hardware-locked boot block when WP# is grounded. This matches legacy BIOS memory maps and prevents accidental overwrite of startup code during firmware updates. The SST39VF1601C-70-4I-B3KE-T datasheet Table 2 and Figure 5 confirm this configuration is exclusive to the "1C" variant-distinct from the top-boot SST39VF1602C.
Does the SST39VF1601C-70-4I-B3KE-T require an external VPP voltage for programming?
No, the SST39VF1601C-70-4I-B3KE-T generates internal VPP for erase and program operations using its on-chip charge pump, eliminating the need for external high-voltage supplies. This is confirmed in the "Automatic Write Timing" section of the datasheet and Table 9 (VPP min/max = 0000H), making the SST39VF1601C-70-4I-B3KE-T compatible with standard 3.3 V-only system designs.
How does the Auto Low Power mode function in the SST39VF1601C-70-4I-B3KE-T?
The SST39VF1601C-70-4I-B3KE-T enters Auto Low Power mode automatically after a valid read cycle completes, reducing active current from 9 mA to 3 µA. It exits instantly on any address or control signal transition-no access time penalty. This behavior is documented in the "Device Operation" section and applies only after the first address transition post-power-up, not when CE# is held low continuously.
Can the SST39VF1601C-70-4I-B3KE-T be used in systems requiring JEDEC-standard command sets?
Yes, the SST39VF1601C-70-4I-B3KE-T fully conforms to JEDEC Standard JESD21-C for flash EEPROM pinouts and command sets, including CFI Query, Software ID Entry, and standard Program/Erase sequences. This interoperability is explicitly stated in the "PRODUCT DESCRIPTION" and verified in Table 7 command tables-ensuring compatibility with generic flash drivers.
What is the purpose of the RY/BY# pin on the SST39VF1601C-70-4I-B3KE-T?
The RY/BY# pin on the SST39VF1601C-70-4I-B3KE-T is an open-drain ready/busy indicator that pulls low during active erase or program operations and floats high (with external pull-up) when idle. It enables hardware-driven polling without CPU overhead and supports wired-OR connection of multiple flash devices-critical for multi-chip memory subsystems in telecom and industrial systems.
