Product details
Overview
SST39VF1601C-70-4I-MAQE 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 supports sector-, block-, and chip-erase with uniform 2 KWord sectors and flexible block architecture (including one 8 KWord, two 4 KWord, one 16 KWord, and thirty-one 32 KWord blocks), enabling firmware updates in embedded controllers and industrial HMI systems.
For engineers reviewing the SST39VF1601C-70-4I-MAQE datasheet, SST39VF1601C-70-4I-MAQE pinout, SST39VF1601C-70-4I-MAQE application, or SST39VF1601C-70-4I-MAQE equivalent, key selection criteria include boot-block configuration (bottom 8 KWord protected), JEDEC-standard x16 interface timing, RY/BY# status signaling, hardware write protection via WP#, and SuperFlash® technology's fixed erase/program times independent of cycle count.
Technical Context
The SST39VF1601C-70-4I-MAQE implements SST's proprietary SuperFlash® technology with split-gate cells and thick-oxide tunneling injectors, delivering guaranteed 100,000 program/erase cycles and >100 years data retention. Its architecture supports simultaneous read-while-erase-suspend functionality using DQ2/DQ6 toggle bits and DQ7 data polling for status detection.
It conforms to JEDEC standard x16 flash pinouts and command sets, features latched address/data buses, and integrates hardware reset (RST#), ready/busy# (RY/BY#) open-drain output with external pull-up requirement, and security ID space (128-bit factory + 128-word user programmable). The device operates in Auto Low Power mode (3 µA standby) after valid reads, reducing active current to 2 mA/MHz.

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-MAQE | Top-boot block protection (FE000H–FFFFFH) instead of bottom-boot; identical timing, voltage, and density | Used where bootloader resides in highest memory region, not lowest | Select only if system firmware layout requires top-boot architecture - not pin-compatible due to different protected address range |
| MX29LV160ETTI-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V, but uses different command set and lacks Erase-Suspend; no Security ID | Lower-cost alternative where suspend/resume and secure ID are not required | Valid for basic firmware storage; requires redesign of flash driver due to non-JEDEC-compatible command sequences |
Compared with SST39VF1602C-70-4I-MAQE, the SST39VF1601C-70-4I-MAQE provides bottom-boot protection essential for legacy bootloader placement, while MX29LV160ETTI-70G offers cost savings at the expense of SuperFlash®'s fixed timing and advanced security features.

FAQ
What boot block configuration does SST39VF1601C-70-4I-MAQE implement?
The SST39VF1601C-70-4I-MAQE implements bottom-boot block protection, safeguarding the lowest 8 KWord (00000H–01FFFH) of memory from accidental erase or program operations when the WP# pin is grounded. This configuration ensures bootloader code integrity in systems where startup routines reside at the base of the address space. Unlike the SST39VF1602C variant, the SST39VF1601C-70-4I-MAQE does not protect the top address region.
How does SST39VF1601C-70-4I-MAQE indicate completion of an erase or program operation?
The SST39VF1601C-70-4I-MAQE provides three concurrent status mechanisms: Ready/Busy# (RY/BY#) open-drain pin (pulled low during operation), Data# Polling via DQ7 (complement toggles until completion), and Toggle Bit monitoring on DQ6 (alternates 1/0 during operation, stabilizes at completion). These methods allow host software to poll asynchronously or use hardware interrupts, with RY/BY# requiring an external 10–100 kΩ pull-up resistor.
Does SST39VF1601C-70-4I-MAQE support simultaneous read and erase operations?
Yes, the SST39VF1601C-70-4I-MAQE supports Erase-Suspend/Erase-Resume functionality. When an Erase-Suspend command (B0H) is issued, the device pauses the ongoing sector or block erase and enters read mode within 20 µs, allowing the host to read data from any non-suspended sector. The SST39VF1601C-70-4I-MAQE resumes the suspended erase upon receiving the Erase-Resume command (30H), maintaining data integrity throughout.
What package type is used by SST39VF1601C-70-4I-MAQE?
The SST39VF1601C-70-4I-MAQE uses a 48-ball WFBGA (Wafer-Level Fine-Pitch Ball Grid Array) package measuring 4 mm × 6 mm, designated by the "MAQE" suffix. This ultra-compact, RoHS-compliant package supports high-density PCB layouts and provides thermal and electrical performance suitable for industrial and automotive applications operating across –40°C to +85°C.
Can SST39VF1601C-70-4I-MAQE be used with a 3.3 V-only system without level shifting?
Yes, the SST39VF1601C-70-4I-MAQE operates natively from 2.7 V to 3.6 V and is fully compatible with 3.3 V logic interfaces. Its CMOS I/O structure meets JEDEC standards for x16 flash memories, eliminating the need for external level shifters when interfacing with 3.3 V microcontrollers, FPGAs, or ASICs. All control signals (CE#, OE#, WE#, WP#, RST#) and data lines (DQ0–DQ15) are 3.3 V tolerant.
