Product details
Overview
SST39VF1601C-70-4I-B3KE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus (MPF+) memory IC with 70 ns read access time, single 2.7–3.6 V supply operation, and bottom-boot block protection. It delivers 100,000 program/erase cycles endurance and >100-year data retention, supporting embedded firmware storage in industrial controllers and legacy BIOS modules.
For engineers reviewing the SST39VF1601C-70-4I-B3KE datasheet, SST39VF1601C-70-4I-B3KE pinout, SST39VF1601C-70-4I-B3KE application, or SST39VF1601C-70-4I-B3KE equivalent, key selection criteria include boot-block architecture (bottom 8 KWord), JEDEC-compliant x16 interface timing, RY/BY# status signaling, and hardware write-protection via WP# pin - all critical for secure, field-upgradable firmware designs.
Technical Context
The SST39VF1601C-70-4I-B3KE implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its command-set architecture supports JEDEC-standard software data protection (SDP) with three-byte unlock sequences for word-program and six-byte sequences for sector/block/chip-erase operations.
It features dual status detection: Data# Polling (DQ7) and Toggle Bit (DQ6/DQ2), plus open-drain RY/BY# output requiring external 10 kΩ–100 kΩ pull-up. The device includes hardware reset (RST#), latched address/data paths, and a 256-word Security ID space (128-bit factory + 128-word user programmable).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1M × 16 (16 Mbit); supports x16 parallel bus interface with A0–A19 addressing |
| Read Access Time | 70 ns; enables direct execution from flash (XIP) in microcontroller systems without wait states at moderate clock speeds |
| Supply Voltage | 2.7–3.6 V; compatible with 3.3 V logic domains and tolerant of brown-out conditions down to 2.7 V |
| Endurance & Retention | 100,000 cycles / >100 years; validated for long-life industrial firmware updates and configuration storage |
| Erase Architecture | Uniform 2 KWord sectors + flexible blocks (one 8K, two 4K, one 16K, thirty-one 32K); allows granular firmware patching |
| Write Protection | Hardware bottom-boot block (00000H–01FFFH); prevents accidental overwrite of bootloader code when WP# = low |
| Power Consumption | 9 mA active (5 MHz), 3 µA standby/auto-low-power; reduces system-level power budget in always-on edge devices |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3 (MSL3).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | AMS = A19; during sector-erase, A11–A19 select sector; during block-erase, A15–A19 select block |
| DQ0–DQ15 | Data I/O | Bi-directional x16 data bus; outputs tri-stated when CE# or OE# high; internally latched on write |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write; controls address latch timing on falling edge |
| OE# | Output Enable | Active-low output gate; used with CE# to initiate read; high disables output drivers |
| WE# | Write Enable | Active-low write control; latches data on rising edge; initiates internal program/erase after sixth pulse |
| WP# | Write Protect | Active-low hardware lock for bottom 8 KWord boot block (00000H–01FFFH); floating = internally pulled high |
| RST# | Reset | Active-low hardware reset; forces return to read mode; terminates in-progress erase/program |
| RY/BY# | Ready/Busy# | Open-drain status output; low = busy (erase/program in progress); requires external pull-up resistor |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; decoupling required per JEDEC guidelines |
| VSS | Ground | Primary ground reference; two dedicated VSS pins in WFBGA package |
| NC | No Connection | Unbonded pads (e.g., ball A19, C1, E1, G1 in WFBGA); must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows temporary halt of sector/block erase to read or program other locations - essential for real-time firmware update without full device stall |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid read access - cuts dynamic power by >99% during idle polling intervals |
| Security ID Space | 256-word (128-bit factory + 128-word user) tamper-resistant identity storage - supports secure boot authentication and device binding |
| Common Flash Interface (CFI) | Standardized query mode (98H command) provides runtime discoverability of geometry, timing, and command set - simplifies BSP portability across flash vendors |
| JEDEC Pinout & Command Compliance | Full x16 memory pin compatibility and command mapping per JEDEC Standard JESD21-C - ensures drop-in replacement in legacy designs |

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-B3KE | Top-boot block (FE000H–FFFFFH) instead of bottom-boot; identical timing, voltage, and command set | Used where bootloader resides at top of address space (e.g., newer x86 BIOS layouts) | Select based on boot block location alignment with host processor reset vector mapping |
| MX29LV160DTTI-70G | 16 Mbit x16, 70 ns, but uses different command sequences and lacks Security ID; no erase-suspend | Lower-cost alternative where secure identity and background erase are not required | Valid for cost-sensitive consumer electronics where firmware update frequency and security are minimal |
Compared with SST39VF1602C-70-4I-B3KE and MX29LV160DTTI-70G, the SST39VF1601C-70-4I-B3KE uniquely combines bottom-boot protection, erase-suspend, and factory/user Security ID - making it optimal for safety-critical firmware storage where bootloader integrity and device identity binding are mandatory.

FAQ
What boot block architecture does the SST39VF1601C-70-4I-B3KE implement?
The SST39VF1601C-70-4I-B3KE implements bottom-boot block protection covering address range 00000H–01FFFH (8 KWords). This architecture safeguards the reset vector and initial boot code from accidental erasure or programming when WP# is asserted low. Unlike the SST39VF1602C variant, which protects the top 8 KWord block, the SST39VF1601C-70-4I-B3KE is optimized for systems where the bootloader resides at the lowest physical address.
How does the SST39VF1601C-70-4I-B3KE indicate completion of an erase or program operation?
The SST39VF1601C-70-4I-B3KE provides three concurrent status mechanisms: Data# Polling (DQ7 toggles complement until completion), Toggle Bit (DQ6 alternates between 1 and 0 during operation), and Ready/Busy# (RY/BY# open-drain output pulled low during activity). All three are valid after the rising edge of the sixth WE# pulse for erase operations and fourth WE# pulse for program operations - enabling robust, interrupt-driven firmware update routines.
Does the SST39VF1601C-70-4I-B3KE support simultaneous read and erase operations?
Yes, the SST39VF1601C-70-4I-B3KE supports Erase-Suspend/Erase-Resume functionality. Issuing the B0H command halts an ongoing sector or block erase, allowing reads from any non-suspended location or word-programming into unprotected sectors. DQ2 toggling indicates erase-suspended status. This capability enables real-time diagnostics and partial firmware updates without full device interruption - a key advantage over basic NOR flash devices.
What is the purpose of the Security ID feature in the SST39VF1601C-70-4I-B3KE?
The SST39VF1601C-70-4I-B3KE includes a 256-word Security ID space: 128 bits factory-programmed by SST and 128 words user-programmable. This space supports secure device binding, cryptographic key storage, and calibration data anchoring. Once locked via the User Security ID Program Lock-Out command, the user segment becomes immutable - satisfying traceability and anti-counterfeiting requirements in regulated industries like medical and aerospace.
Is the SST39VF1601C-70-4I-B3KE pin-compatible with standard JEDEC x16 flash memories?
Yes, the SST39VF1601C-70-4I-B3KE conforms fully to JEDEC Standard JESD21-C for x16 flash pinouts and command sets. Its 48-ball WFBGA footprint matches industry-standard 48-ball packages, and its command protocol (including unlock sequences, sector/block addresses, and status reporting) aligns with JEDEC specifications - enabling drop-in replacement in existing designs that comply with this standard.
