Product details
Overview
SST39WF1601-70-4C-Y1QE from Silicon Storage Technology is a 16 Mbit (1M × 16) Multi-Purpose Flash Plus (MPF+) memory IC operating at 1.65–1.95 V, featuring 70 ns read access time, bottom 32 KWord hardware block protection, and JEDEC-standard x16 asynchronous interface - used for firmware storage and configuration in embedded controllers and industrial microprocessor systems.
For engineers reviewing the SST39WF1601-70-4C-Y1QE datasheet, SST39WF1601-70-4C-Y1QE pinout, SST39WF1601-70-4C-Y1QE application, or SST39WF1601-70-4C-Y1QE equivalent, key selection considerations include its single-supply 1.65–1.95 V operation, WFBGA-48 package with bottom-boot architecture, sector/block/chip erase capabilities, Auto Low Power mode (5 µA), and hardware write-protect via WP# pin.
Technical Context
The SST39WF1601-70-4C-Y1QE implements SuperFlash split-gate technology enabling fixed erase/program times independent of cycle count, eliminating software de-rating. It supports JEDEC-standard command sets including CFI Query, Software ID Entry, and Security ID programming with factory- and user-programmable 128-bit segments.
Its control logic handles latched address/data timing with WE#/CE# edge-sensitive strobes, supports Erase-Suspend/Resume for concurrent read/program during erase, and uses DQ6/DQ7 status bits (Toggle Bit/Data# Polling) for end-of-write detection - all compliant with x16 flash pin assignments and asynchronous bus protocols.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1,048,576 × 16-bit words) - supports full firmware image storage for mid-complexity microcontrollers. |
| Read Access Time | 70 ns - enables direct execution (XIP) from flash in systems with ≤14 MHz bus timing budgets. |
| Supply Voltage | 1.65–1.95 V - compatible with low-voltage SoC I/O domains and eliminates need for level shifters. |
| Endurance | 100,000 program/erase cycles - sufficient for field-updatable firmware with infrequent reprogramming. |
| Data Retention | >100 years - validated for long-lifecycle industrial deployments without refresh. |
| Erase Granularity | Uniform 2 KWord sectors (4 KB) and 32 KWord blocks (64 KB) - enables fine-grained firmware partitioning and OTA update management. |
| Write Protection | Hardware bottom-block protection (000000H–007FFFH) via WP# pin - prevents accidental overwrite of boot code. |
| Package | 48-ball WFBGA (5 mm × 6 mm) - surface-mount footprint optimized for high-density PCB layouts. |
Pinout & Package
48-ball WFBGA (5 mm × 6 mm, balls facing down), RoHS-compliant, lead-free construction per JEDEC MO-245.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 16-bit address bus (A0–A15) + 4 MSB (A16–A19); AMS = A19 selects boot block during protection. |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with tri-state outputs controlled by CE# and OE#. |
| CE# | Chip Enable | Active-low chip select; device enters standby (5 µA) when high. |

| WE# | Write Enable | Active-low strobe for latching addresses/data during program/erase command sequences. |
| WP# | Write Protect | Active-low hardware lock for bottom 32 KWord boot block (000000H–007FFFH). |
| RST# | Reset | Active-low hardware reset; terminates in-progress operations and forces return to read mode. |
| VDD | Power Supply | 1.65–1.95 V core supply; internal charge pump generates VPP for erase/program. |
| VSS | Ground | Reference ground for all I/O and core logic; two dedicated VSS balls for noise reduction. |
| NC | No Connect | Unbonded pins (e.g., ball positions C1, D1, G1, H1, J1, K1, L1, L2, L3, L4, L5, L6) - must be left floating or grounded per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash Technology | Split-gate cell with thick-oxide tunneling injector delivers stable 70 ns read time and fixed 36 ms sector/block erase - no performance degradation over 100,000 cycles. |
| Auto Low Power Mode | Reduces active read current from 9 mA to 5 µA after valid read access - cuts dynamic power by >99% during idle polling in always-on systems. |
| Erase-Suspend/Resume | Halts sector/block erase within 20 µs to allow read from unprotected regions or program into non-suspended sectors - enables real-time firmware validation during updates. |
| Security ID Space | 256-bit segmented space (128-bit factory ID + 128-bit user-programmable) locked permanently after programming - supports secure boot authentication and device binding. |
| JEDEC CFI Compliance | Supports both SST-specific and general CFI Query modes (via 5555H/98H or 55H/98H) - enables automatic flash detection and parameter retrieval in bootloader environments. |
| Hardware Block Protection | Dedicated bottom-boot architecture (SST39WF1601) protects 000000H–007FFFH - ensures bootloader integrity without software intervention or fuse settings. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX29LV160DTTC-70G | 3.0 V supply (2.7–3.6 V), top-boot architecture, no Auto Low Power mode, 70 ns access, 48-TSOP package | Requires level-shifting for 1.8 V systems; lacks suspend/resume and security ID features | Select when legacy 3 V design compatibility and TSOP footprint are mandatory; not drop-in for SST39WF1601-70-4C-Y1QE's voltage or package. |
| S29GL032N90TFIR20 | 3.0 V supply, 32 Mbit density, 90 ns access, 64-ball BGA, supports common flash interface (CFI) but no Security ID | Higher density and slower timing; no hardware bottom-block protection or erase-suspend | Choose for larger firmware images where 1.8 V operation is not required and security features are secondary. |
Compared with MX29LV160DTTC-70G and S29GL032N90TFIR20, the SST39WF1601-70-4C-Y1QE uniquely combines 1.65–1.95 V operation, bottom-boot protection, Auto Low Power mode, and integrated Security ID - making it optimal for space-constrained, low-power, safety-critical embedded systems requiring guaranteed boot integrity.

Manufacturer
Silicon Storage Technology (SST) was a fabless semiconductor company specializing in high-reliability flash memory solutions, acquired by Microchip Technology in 2017. Its SuperFlash technology is now integrated into Microchip's memory portfolio.
The SST39WF1601-70-4C-Y1QE belongs to the Multi-Purpose Flash Plus (MPF+) family, designed specifically for low-voltage embedded systems needing robust firmware storage with hardware-based protection, long-term data retention, and deterministic erase/program timing.
FAQ
What is the operating voltage range for SST39WF1601-70-4C-Y1QE?
The SST39WF1601-70-4C-Y1QE operates exclusively within 1.65 V to 1.95 V. It does not support 3.3 V or 2.5 V supplies. This narrow range enables direct interfacing with 1.8 V I/O domains without level translation, and internal charge pump generation of VPP ensures reliable erase/program functionality across the entire voltage window.
Does SST39WF1601-70-4C-Y1QE support JEDEC-standard command sets?
Yes, the SST39WF1601-70-4C-Y1QE fully complies with JEDEC Standard JESD21-C for Flash EEPROM Pin Assignments and Command Sets. It supports both SST-specific and general Common Flash Interface (CFI) Query modes, Software Product Identification, Sector/Block/Chip-Erase commands, and Erase-Suspend/Resume - ensuring interoperability with standard flash-aware bootloaders and programming tools.
How does hardware block protection work on SST39WF1601-70-4C-Y1QE?
The SST39WF1601-70-4C-Y1QE implements bottom-block hardware protection: when WP# is driven low, program and erase operations are disabled for the bottom 32 KWord (000000H–007FFFH). This region is preconfigured as the boot block. If WP# is left floating, an internal pull-up holds it high, leaving the boot block unprotected - requiring explicit PCB-level grounding for protection.
What is the purpose of the RST# pin on SST39WF1601-70-4C-Y1QE?
The RST# pin on SST39WF1601-70-4C-Y1QE provides hardware-initiated recovery: holding RST# low for ≥TRP (100 ns min) terminates any in-progress program or erase operation and forces immediate return to read mode. After release, a minimum TRHR (100 ns) delay is required before valid reads - critical for system-level fault recovery and safe power-cycle handling.
Can SST39WF1601-70-4C-Y1QE be used in automotive applications?
The SST39WF1601-70-4C-Y1QE is rated for industrial temperature range (-40°C to +85°C) and meets RoHS compliance, but it is not AEC-Q100 qualified. While used in automotive body control modules where qualification is not mandated, designers requiring formal automotive qualification should verify system-level compliance testing or consider Microchip's AEC-Q100-certified successors derived from this MPF+ family.
