Product details
Overview
SST39VF1601C-70-4C-MAQE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus (MPF+) memory IC with JEDEC-standard x16 interface, 70 ns read access time, and bottom-boot block architecture. It operates from a single 2.7–3.6 V supply, supports hardware write protection via WP#, and delivers 100,000 program/erase cycles with >100 years data retention - ideal for embedded firmware storage in industrial controllers and legacy system BIOS.
For engineers reviewing the SST39VF1601C-70-4C-MAQE datasheet, SST39VF1601C-70-4C-MAQE pinout, SST39VF1601C-70-4C-MAQE application, or SST39VF1601C-70-4C-MAQE equivalent, key selection considerations include bottom-boot block address range (00000H–01FFFH), 48-ball WFBGA (4mm × 6mm) package, sector/block/chip erase capability, RY/BY# status signaling, and SuperFlash® technology's fixed erase/program timing independent of cycle count.
Technical Context
The SST39VF1601C-70-4C-MAQE implements SST's proprietary SuperFlash® split-gate cell architecture with thick-oxide tunneling injector, enabling guaranteed 100,000 endurance cycles and >100-year data retention. Its JEDEC-compliant x16 bus interface uses latched address/data with standard CE#/OE#/WE# control logic and supports Auto Low Power mode (3 µA standby, 3 µA auto-low-power).
It features uniform 2 KWord sectors and flexible block architecture (thirty-one 32 KWord, one 16 KWord, two 4 KWord, one 8 KWord blocks), with bottom-boot block protection (8 KWord at 00000H–01FFFH). Erase-suspend/resume, security ID (128-bit factory + 128-word user), and CFI query support are integrated.

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1602C-70-4C-MAQE | Top-boot block (FE000H–FFFFFH); identical timing, endurance, and package | Requires BIOS/firmware image mapped to top of address space instead of bottom | Select only if system design uses top-boot memory layout and requires identical pinout/package |
| MX29LV160ETTI-70G | 16 Mbit x16, 70 ns, 2.7–3.6 V, but uses different command set and lacks Security ID/CFI Query | Compatible for basic read/write/erase, but not drop-in for secure ID or CFI-based auto-configuration | Choose when cost sensitivity outweighs need for security features or runtime flash interrogation |
Compared with SST39VF1602C-70-4C-MAQE, the SST39VF1601C-70-4C-MAQE provides bottom-boot protection essential for legacy BIOS maps, while MX29LV160ETTI-70G offers functional parity for simple firmware storage but omits security and CFI capabilities required for certified or adaptive systems.

FAQ
What is the boot block configuration of the SST39VF1601C-70-4C-MAQE?
The SST39VF1601C-70-4C-MAQE implements bottom-boot block protection covering the lowest 8 KWord (32 KB) address range from 00000H to 01FFFH. This region is hardware-protected when WP# is grounded, preventing accidental erasure or programming of critical startup code. The SST39VF1601C-70-4C-MAQE differs from the SST39VF1602C variant, which protects the top 8 KWord instead.
Does the SST39VF1601C-70-4C-MAQE support erase-suspend functionality?
Yes, the SST39VF1601C-70-4C-MAQE supports both erase-suspend and erase-resume commands (B0H and 30H respectively). This allows a system to pause an ongoing sector or block erase operation, read data from unprotected regions, or program other sectors, then resume the suspended erase - essential for real-time applications where uninterrupted operation is required.
What package type is used for the SST39VF1601C-70-4C-MAQE?
The SST39VF1601C-70-4C-MAQE is packaged in a 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), marked "MAQE" in Microchip's ordering nomenclature. This ultra-compact package supports high-density PCB layouts and complies with RoHS directives. Pin assignments match JEDEC-standard x16 parallel flash footprints for drop-in compatibility with existing designs using this form factor.
How does the SST39VF1601C-70-4C-MAQE indicate completion of a program or erase operation?
The SST39VF1601C-70-4C-MAQE provides three hardware/software methods: Ready/Busy# (RY/BY#) open-drain output, Data# Polling (DQ7), and Toggle Bit (DQ6). RY/BY# goes high when idle; DQ7 toggles during operation and stabilizes to true data upon completion; DQ6 toggles continuously until operation ends. All methods are valid after the rising edge of the final WE# pulse in the command sequence.
Is the SST39VF1601C-70-4C-MAQE compatible with Common Flash Interface (CFI) hosts?
Yes, the SST39VF1601C-70-4C-MAQE includes full CFI Query support. By issuing the 98H command sequence at address 555H, the host can read standardized CFI parameter tables (e.g., device geometry, voltage ranges, timing, command sets) from fixed memory locations. This enables automatic flash detection and configuration in bootloader or OS-level storage drivers without hard-coded assumptions.
