Product details
Overview
SST39VF801C-70-4I-MAQE from Microchip Technology is a 8 Mbit (512K × 16) CMOS Multi-Purpose Flash Plus memory IC with SuperFlash® technology, operating at 2.7–3.6 V, featuring 70 ns read access time, hardware block protection for bottom 8 KWord boot sector, and JEDEC-standard x16 pinout. It serves as nonvolatile program/data storage in embedded controllers, BIOS firmware modules, and industrial HMI systems.
For engineers reviewing the SST39VF801C-70-4I-MAQE datasheet, SST39VF801C-70-4I-MAQE pinout, SST39VF801C-70-4I-MAQE application, or SST39VF801C-70-4I-MAQE equivalent, key selection considerations include bottom-boot block architecture, TSOP-48 package compatibility, 100,000-cycle endurance, RY/BY# status signaling, and software/hardware data protection schemes.
Technical Context
This device implements a split-gate SuperFlash® cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It supports uniform 2 KWord sector erase, flexible block erase (fifteen 32 KWord + one 16 KWord + two 4 KWord + one 8 KWord), and full-chip erase - all initiated via JEDEC-compliant command sequences.
Operation relies on latched address/data inputs, CMOS I/O compatibility, and three status detection methods: Ready/Busy# (open-drain), Data# Polling (DQ7), and Toggle Bits (DQ6/DQ2). Hardware protection includes WP#-controlled bottom boot block lock, RST# reset, and noise/glitch immunity on WE#/CE#.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF802C-70-4I-MAQE | Top-boot architecture (7E000H–7FFFFH protected), identical timing, voltage, and command set | Used where bootloader resides in top memory region instead of bottom | Select when system design requires top-boot block protection rather than bottom-boot |
| MX29LV800CTTI-70G | Same 8 Mbit x16, 70 ns, 3.0–3.6 V; different command set and CFI implementation; no Erase-Suspend | Lacks suspend/resume; requires full erase before partial update | Choose only if existing driver stack is optimized for Macronix command protocol and suspend capability is not required |
Compared with SST39VF801C-70-4I-MAQE, SST39VF802C-70-4I-MAQE offers identical performance but inverted boot-block location, while MX29LV800CTTI-70G sacrifices erase-suspend functionality for broader ecosystem compatibility - making SST39VF801C-70-4I-MAQE optimal for systems needing real-time firmware patching with guaranteed bootloader protection.

FAQ
What is the boot block configuration of SST39VF801C-70-4I-MAQE?
The SST39VF801C-70-4I-MAQE features bottom-boot block protection covering the lowest 8 KWord (00000H–01FFFH), which is hardware-locked when WP# is grounded. This architecture safeguards bootloader code from accidental overwrite during firmware updates. The protected region is fixed and cannot be reconfigured. SST39VF801C-70-4I-MAQE does not support top-boot configuration - that function is implemented in the SST39VF802C variant.
Does SST39VF801C-70-4I-MAQE require an external VPP voltage for programming?
No, SST39VF801C-70-4I-MAQE does not require external VPP. It uses internal charge pump circuitry to generate necessary high-voltage programming pulses from the single 2.7–3.6 V VDD supply. This eliminates need for dedicated VPP regulators or external high-voltage sources, simplifying board design and reducing BOM cost. All program and erase operations execute autonomously using internally generated voltages.
How is write completion detected on SST39VF801C-70-4I-MAQE?
SST39VF801C-70-4I-MAQE supports three concurrent write completion detection methods: Ready/Busy# (RY/BY#) open-drain signal, Data# Polling on DQ7, and Toggle Bit monitoring on DQ6 (and DQ2 for sector status). RY/BY# requires external pull-up; DQ7 toggles complement during operation then returns true data; DQ6 toggles between 1/0 until completion. These mechanisms enable efficient polling or interrupt-driven firmware handling without fixed timeout delays.
Can SST39VF801C-70-4I-MAQE be used in place of SST39VF802C-70-4I-MAQE?
SST39VF801C-70-4I-MAQE and SST39VF802C-70-4I-MAQE share identical electrical specifications, timing, and command sets, but differ in boot block location: SST39VF801C-70-4I-MAQE protects the bottom 8 KWord (00000H–01FFFH), while SST39VF802C-70-4I-MAQE protects the top 8 KWord (7E000H–7FFFFH). Direct substitution is possible only if the target system's bootloader resides in the bottom region and WP# is correctly routed. PCB layout and firmware address mapping must be verified prior to replacement.
What package type is used in SST39VF801C-70-4I-MAQE?
SST39VF801C-70-4I-MAQE uses a 48-lead TSOP (Thin Small Outline Package) with 12 mm × 20 mm body size and standard JEDEC MO-142AC footprint. The "-MAQE" suffix explicitly denotes this TSOP-48 variant. It is RoHS compliant and pin-compatible with other x16 flash devices in the same package, enabling drop-in replacement in existing designs meeting JEDEC x16 flash mechanical and thermal constraints.
