Product details
Overview
SST39VF1601-70-4I-B3KE-T-MCH 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 bottom 32 KWord hardware block protection. It features sector-erase (2 KWord), block-erase (32 KWord), chip-erase, and erase-suspend/resume capabilities, and is used in embedded firmware storage for industrial controllers and legacy communication modules.
For engineers reviewing the SST39VF1601-70-4I-B3KE-T-MCH datasheet, SST39VF1601-70-4I-B3KE-T-MCH pinout, SST39VF1601-70-4I-B3KE-T-MCH application, or SST39VF1601-70-4I-B3KE-T-MCH equivalent, key selection considerations include its TSOP-48 package, JEDEC x16 flash command set compliance, bottom-boot block protection scheme, and SuperFlash technology's fixed 7 µs word-program time and 100,000-cycle endurance.
Technical Context
This device implements SST's proprietary SuperFlash split-gate cell architecture with thick-oxide tunneling injector, enabling guaranteed 100,000 program/erase cycles and >100-year data retention. It supports standard asynchronous x16 interface timing with CE#, OE#, and WE# control signals, and uses latched address/data buses compatible with legacy microprocessor buses.
Hardware write protection is implemented via the WP# pin, which-when grounded-prevents erase/program operations on the bottom 32 KWord boot block (000000H–007FFFH). The RST# pin provides hardware reset to Read mode, and status detection relies on DQ6 toggle bit and DQ7 data# polling during internal write operations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 organization) |
| Read Access Time | 70 ns - determines maximum bus clock rate for zero-wait-state reads |
| Supply Voltage | 2.7–3.6 V - enables direct interface with 3.3 V logic systems without level shifting |
| Endurance | 100,000 cycles (typical) - supports frequent field firmware updates in industrial gateways |
| Data Retention | >100 years - ensures long-term reliability in unattended infrastructure equipment |
| Word-Program Time | 7 µs (typical) - enables fast incremental code patching without system stall |
| Block-Erase Time | 18 ms (typical) - allows rapid reconfiguration of boot firmware sections |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, standard JEDEC x16 flash footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | A0–A18 used for 1M×16 addressing; A19 is MSB and unused in SST39VF1601 (max address = 000000H–00FFFFH) |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus; tri-stated when CE# or OE# is high; latched internally during writes |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 µA) when high |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read cycles only |
| WE# | Write Enable | Active-low control for all write operations (program/erase); latches command sequences |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block (000000H–007FFFH) |
| RST# | Reset | Active-low hardware abort of ongoing erase/program; forces return to Read mode |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; no separate VPP required (internal generation) |
| VSS | Ground | Two dedicated ground pins (pins 23 and 47) for noise reduction in high-speed reads |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows real-time read access to non-suspended sectors during active erase, enabling firmware hot-swapping |
| Security ID | 256-bit space (128-bit factory + 128-bit user) for device authentication and secure boot binding |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access, cutting power in idle polling loops |
| CFI Support | JEDEC-standard Common Flash Interface enables automatic driver detection and configuration in BIOS/bootloader |
| SuperFlash Reliability | Fixed 7 µs program and 18 ms erase times independent of cycle count - eliminates software de-rating over lifetime |
Applications
| Industrial PLC Firmware Storage | Legacy Telecom Line Card Boot Memory |
|---|---|
Use Scenario: Storing and updating ladder logic firmware in programmable logic controllers deployed in factory automation environments with ambient temperatures up to 85°C. IC Role / Device Role / Timing Role: Nonvolatile boot and application code storage with hardware-protected boot sector to prevent corruption during brown-out recovery.

Use Scenario: Storing UEFI-compatible BIOS image and hardware initialization tables in portable ultrasound and MRI subsystem controllers. IC Role / Device Role / Timing Role: Primary boot memory mapped at reset vector; accessed via 3.3 V PCI/PCIe bridge interface. Use Value: 100,000-cycle endurance supports regulatory-mandated field calibration and safety firmware patches across 15+ year product lifecycle. |
Use Scenario: Retaining vehicle-specific calibration parameters (e.g., window lift profiles, mirror positioning) in BCMs subjected to automotive temperature cycling (-40°C to 125°C). IC Role / Device Role / Timing Role: EEPROM-replacement flash storing infrequently updated but mission-critical configuration data. Use Value: >100-year data retention and hardware block protection eliminate risk of parameter loss during battery disconnect events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C | Same density and pinout; improved 55 ns access time and enhanced ESD rating (4 kV HBM) | Recommended for new designs per Microchip; supports higher-speed bus interfaces | Select when designing new systems requiring longer-term availability and tighter timing margins |
| MX29LV160ETTI-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V; top-boot block protection (not bottom-boot); different command set timing | Lacks erase-suspend; requires modified driver for sector unlock sequence | Consider only if existing design already uses Macronix-compatible firmware and board layout accommodates identical TSOP-48 footprint |
Compared with SST39VF1601C, the SST39VF1601-70-4I-B3KE-T-MCH offers identical functionality but with older timing specs and discontinued status; versus MX29LV160ETTI-70G, it provides bottom-boot protection and erase-suspend-critical for safe in-field updates-but requires SST-specific command handling.

FAQ
What does the "-70" suffix indicate in SST39VF1601-70-4I-B3KE-T-MCH?
The "-70" denotes 70 ns maximum read access time under specified conditions (VDD = 3.0–3.6 V, TA = -40°C to +85°C). This timing governs the minimum address-to-data valid delay in asynchronous read cycles and is critical for compatibility with legacy microprocessor bus timing budgets. SST39VF1601-70-4I-B3KE-T-MCH meets this spec across its full industrial temperature range.
Is SST39VF1601-70-4I-B3KE-T-MCH pin-compatible with SST39VF1602?
No. SST39VF1601-70-4I-B3KE-T-MCH uses A0–A18 for addressing (1M × 16) and has bottom-boot protection, while SST39VF1602 implements top-boot protection and uses A19 as MSB for its extended address map. Though both use 48-lead TSOP packages, their boot block locations and address decoding differ, making them not interchangeable without firmware and hardware revision.
Does SST39VF1601-70-4I-B3KE-T-MCH require an external VPP voltage?
No. SST39VF1601-70-4I-B3KE-T-MCH integrates internal charge pump circuitry for high-voltage generation during program and erase operations. It operates entirely from a single 2.7–3.6 V supply (VDD), eliminating need for external VPP pins or regulators - simplifying PCB design and reducing BOM cost.
How is hardware block protection configured on SST39VF1601-70-4I-B3KE-T-MCH?
SST39VF1601-70-4I-B3KE-T-MCH implements bottom 32 KWord hardware block protection. When WP# is driven low, program and erase operations are disabled for addresses 000000H–007FFFH. If WP# is left floating, an internal pull-up holds it high, disabling protection. This scheme safeguards bootloader code against accidental overwrite during field firmware updates.
What JEDEC standards does SST39VF1601-70-4I-B3KE-T-MCH comply with?
SST39VF1601-70-4I-B3KE-T-MCH complies with JEDEC Standard JESD21-C for x16 flash pinouts and JESD22-A117 for data retention. Its command set aligns with JEDEC JESD22-A111 (endurance) and it supports Common Flash Interface (CFI) per JEP137-B, enabling standardized driver auto-detection in UEFI and RTOS environments.
