Product details
Overview
SST39VF801C-70-4I-MAQE-T from Microchip Technology is a 8 Mbit (512K × 16) CMOS Multi-Purpose Flash Plus memory IC with SuperFlash® technology, designed for embedded program/data storage in microcontroller-based systems. It operates from 2.7–3.6 V, delivers 70 ns read access time, supports sector/block/chip erase, and features hardware write protection via WP# pin for bottom-boot block protection (00000H–01FFFH).
For engineers reviewing the SST39VF801C-70-4I-MAQE-T datasheet, SST39VF801C-70-4I-MAQE-T pinout, SST39VF801C-70-4I-MAQE-T application, or SST39VF801C-70-4I-MAQE-T equivalent, this page provides verified functional identity, JEDEC-compliant x16 interface timing, boot-block architecture details, endurance (100,000 cycles), and RoHS-compliant 48-ball WFBGA (4 mm × 6 mm) package mapping.
Technical Context
The SST39VF801C-70-4I-MAQE-T implements a split-gate SuperFlash® cell architecture with thick-oxide tunneling injector, enabling fixed erase/program times independent of cycle count. It uses standard JEDEC x16 flash command sets-including six-byte sector/block/chip erase sequences-and supports Data# Polling (DQ7), Toggle Bit (DQ6/DQ2), and open-drain RY/BY# for end-of-write detection.
Hardware data protection includes noise/glitch immunity (<5 ns pulse rejection), VDD power-up/down detection (<1.5 V inhibit), and bottom-boot block protection via WP# grounding. The device integrates latched address/data paths, Auto Low Power mode (3 µA standby), and CFI Query support for system-level identification and configuration.
Key Specifications

| Boot Block Protection | Bottom 8 KWord (00000H–01FFFH) protected when WP# = low - safeguards bootloader code against corruption |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm), RoHS-compliant, ball pitch 0.5 mm. Pinout conforms to JEDEC-standard x16 flash interface and matches Figure 4 (DS25041A, p.5).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus; AMS = A18; sector erase uses A11–A18, block erase uses A15–A18 |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; outputs tri-stated when CE# or OE# high; latched during writes |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write operations; controls address latch timing |

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-T | Top-boot architecture (7E000H–7FFFFH protected); identical timing, voltage, and package | Used where bootloader resides in top memory region; not interchangeable without firmware address remapping | Select only if top-boot block protection aligns with system memory map |
| MX29LV800CTTI-70G | 70 ns access, 3.0–3.6 V only, no Auto Low Power mode, different command set (no Erase-Suspend) | Lacks suspend/resume and security ID; requires modified driver software for erase/program flow | Choose when cost sensitivity outweighs advanced features and legacy driver reuse is prioritized |
Compared with SST39VF801C-70-4I-MAQE-T, the SST39VF802C variant offers top-boot protection instead of bottom-boot, while the MX29LV800CTTI-70G lacks SuperFlash® benefits like fixed erase time and suspend capability-making it less suitable for real-time firmware update scenarios.

FAQ
What is the exact memory organization and density of the SST39VF801C-70-4I-MAQE-T?
The SST39VF801C-70-4I-MAQE-T is organized as 512K × 16, delivering 8 Mbit (1,048,576 bytes) of nonvolatile storage. Its x16 data bus interface allows direct connection to 16-bit microcontrollers without multiplexing or external data-width conversion logic. This organization is confirmed in DS25041A, Section "Product Description" and Table 1.
Does the SST39VF801C-70-4I-MAQE-T require an external VPP voltage for programming or erasing?
No, the SST39VF801C-70-4I-MAQE-T does not require an external VPP voltage. It generates all necessary high-voltage programming pulses internally using its on-chip charge pump, operating solely from the 2.7–3.6 V VDD supply. This is explicitly stated in the "Automatic Write Timing" feature and Table 9 (VPP min/max = 00H).
How is hardware write protection implemented on the SST39VF801C-70-4I-MAQE-T?
Hardware write protection on the SST39VF801C-70-4I-MAQE-T is implemented via the WP# pin, which protects the bottom 8 KWord boot block (00000H–01FFFH) when held low. If WP# is left floating, it is internally pulled high, disabling protection. This behavior is defined in Table 4 and the "Hardware Block Protection" section of DS25041A.
What package type and dimensions does the SST39VF801C-70-4I-MAQE-T use?
The SST39VF801C-70-4I-MAQE-T uses a 48-ball WFBGA package measuring 4 mm × 6 mm with 0.5 mm ball pitch. This ultra-compact footprint is specified in the "Packages Available" section and illustrated in Figure 4 of DS25041A. The suffix "MAQE-T" explicitly denotes this WFBGA variant.
Can the SST39VF801C-70-4I-MAQE-T be used in systems requiring AEC-Q100 qualification?
The SST39VF801C-70-4I-MAQE-T itself is not AEC-Q100 qualified; however, it is rated for industrial temperature range (–40°C to +85°C) and widely deployed in automotive infotainment subsystems where full AEC-Q100 is not mandated for secondary memory. For AEC-Q100–compliant alternatives, consult Microchip's automotive-grade SST39VFxxxC derivatives.
