Product details
Overview
SST39VF802C-70-4C-MAQE-T from Microchip Technology is a 8 Mbit (512K × 16) CMOS Multi-Purpose Flash Plus memory IC with SuperFlash® technology, designed for embedded firmware and configuration storage in industrial controllers and communication modules. It operates from 2.7–3.6V, delivers 70 ns read access time, supports sector/block/chip erase, and features hardware write protection via WP# pin.
For engineers reviewing the SST39VF802C-70-4C-MAQE-T datasheet, SST39VF802C-70-4C-MAQE-T pinout, SST39VF802C-70-4C-MAQE-T application, or SST39VF802C-70-4C-MAQE-T equivalent, this page provides verified technical context, JEDEC-compliant x16 interface details, boot-block architecture, RY/BY# status signaling, and real-world flash endurance and power behavior.
Technical Context
The SST39VF802C-70-4C-MAQE-T implements a split-gate SuperFlash® cell architecture enabling fixed 7 µs word-program and 18 ms sector-erase times independent of cycle count. Its JEDEC-standard x16 parallel interface uses CE#, OE#, and WE# control signals with latched address/data buses and supports toggle-bit (DQ6/DQ2) and data-polling (DQ7) write completion detection.
This device integrates top-boot block protection (8 KWord at 7E000H–7FFFFH), hardware reset (RST#), ready/busy open-drain output (RY/BY#), and 128-bit factory Security ID plus 128-word user-programmable Security ID space - all compliant with Common Flash Interface (CFI) query mode.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16 organization), enabling compact firmware storage without external data-width conversion |
| Read Access Time | 70 ns - meets timing requirements for 14 MHz bus interfaces in legacy microcontroller systems |
| Supply Voltage | 2.7–3.6 V - compatible with single-supply 3.3 V systems and tolerant of brown-out conditions down to 2.7 V |
| Endurance | 100,000 program/erase cycles - sufficient for field-upgradable firmware with infrequent updates |
| Data Retention | Greater than 100 years - ensures long-term reliability in unattended industrial deployments |
| Active Current | 5 mA typical at 5 MHz - enables low-power operation in battery-backed or energy-constrained host systems |
| Erase Architecture | Uniform 2 KWord sectors + flexible blocks (1×8K, 2×4K, 1×16K, 15×32K) - supports granular firmware partitioning |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, MAQE suffix), RoHS-compliant, suitable for high-density PCB layouts requiring minimal footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | AMS = A18; A18–A0 provide full 19-bit addressing for 512K × 16 array; AMS–A11 select sector during erase |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; outputs tri-stated when CE# or OE# high; latched internally during write |
| CE# | Chip Enable | Active-low chip select; device enters standby (3 µA) when high; required low for all operations |
| OE# | Output Enable | Active-low output gate; controls DQ bus drive; must be low with CE# for valid read data |
| WE# | Write Enable | Active-low control for program/erase command latching; rising edge initiates internal operation |
| WP# | Write Protect | Active-low hardware lock for top 8 KWord boot block (7E000H–7FFFFH); prevents accidental firmware overwrite |
| RST# | Reset | Active-low hardware reset; forces return to read mode and aborts in-progress erase/program |
| RY/BY# | Ready/Busy# | Open-drain status indicator; pulled low during erase/program; requires external 10–100 kΩ pull-up |
| VDD | Power Supply | 2.7–3.6 V supply; powers core logic and SuperFlash® array; internal VPP generation eliminates external pump |
| VSS | Ground | Reference ground for all I/O and core circuitry; two dedicated pins ensure stable return path |
Key Features
| Feature | Design Value |
|---|---|
| SuperFlash® Technology | Fixed 7 µs word-program and 18 ms erase times across full lifecycle - eliminates software de-rating and timing margin expansion |
| Top Boot Block Protection | Hardware-enforced 8 KWord protection (7E000H–7FFFFH) - safeguards bootloader code from corruption during field updates |
| Erase-Suspend/Resume | Allows read access to non-suspended sectors during active erase - enables real-time status monitoring without halting firmware update |
| Security ID Space | Factory-programmed 128-bit ID + 128-word user space - supports secure device authentication and firmware binding |
| Auto Low Power Mode | Reduces active read current from 5 mA to 3 µA after valid access - cuts dynamic power by >99% in polling-based status checks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF801C-70-4C-MAQE-T | Bottom-boot architecture (00000H–01FFFH protected); identical timing, voltage, and package | Requires firmware image layout with protected bottom block instead of top block | Select when bootloader resides in lowest memory region and top-block protection is unnecessary |
| MX29LV800CTTI-70G | 70 ns access, 3.0–3.6 V only, no RST# pin, different CFI descriptor layout | Lacks hardware reset and top-boot block mapping; requires modified driver initialization sequence | Choose for cost-sensitive designs where RST# and boot-block flexibility are not required |
Compared with SST39VF802C-70-4C-MAQE-T, the SST39VF801C variant shifts protection to the bottom block - simplifying layout for legacy bootloaders - while the MX29LV800CTTI offers lower unit cost but removes RST# and alters CFI compliance, increasing porting effort.

FAQ
What is the boot block configuration of the SST39VF802C-70-4C-MAQE-T?
The SST39VF802C-70-4C-MAQE-T implements top-boot block protection covering the 8 KWord address range 7E000H–7FFFFH. This region is hardware-protected when WP# is grounded, making it ideal for safeguarding bootloader code. The SST39VF802C-70-4C-MAQE-T differs from the SST39VF801C series, which protects the bottom 8 KWord (00000H–01FFFH). This top-boot architecture is confirmed in Table 4 and Figure 2 of the DS25041A datasheet.
Does the SST39VF802C-70-4C-MAQE-T require an external VPP voltage?
No, the SST39VF802C-70-4C-MAQE-T does not require an external VPP voltage. It uses internal VPP generation powered solely by the 2.7–3.6 V VDD supply, eliminating the need for auxiliary high-voltage circuitry. This is explicitly stated in the "Automatic Write Timing" feature list and confirmed in Table 9 (VPP min/max = 0000H), meaning the device is fully single-supply compatible.
How is write completion detected on the SST39VF802C-70-4C-MAQE-T?
The SST39VF802C-70-4C-MAQE-T supports three hardware-assisted write completion detection methods: Ready/Busy# (RY/BY#) open-drain output, Data# Polling (DQ7), and Toggle Bits (DQ6 and DQ2). RY/BY# requires an external pull-up resistor and transitions high when ready; DQ7 toggles during operation and stabilizes to true data upon completion; DQ6 toggles continuously until operation ends. All methods are documented in Section "Write Operation Status Detection" of DS25041A.
What package type does the SST39VF802C-70-4C-MAQE-T use?
The SST39VF802C-70-4C-MAQE-T uses a 48-ball WFBGA (Wafer-Level Fine-Pitch Ball Grid Array) package measuring 4 mm × 6 mm, identified by the "MAQE" suffix per Microchip's packaging nomenclature. This ultra-compact RoHS-compliant package is optimized for high-density PCB layouts and is distinct from the TSOP and TFBGA variants offered in the same family.
Is the SST39VF802C-70-4C-MAQE-T compatible with JEDEC-standard x16 flash interfaces?
Yes, the SST39VF802C-70-4C-MAQE-T conforms fully to JEDEC standard pinouts and command sets for x16 parallel flash memory devices. Its address/data/control signal mapping (A0–A18, DQ0–DQ15, CE#/OE#/WE#/WP#/RST#/RY/BY#) matches JEDEC MO-141 and JESD21-C specifications, enabling drop-in compatibility with existing x16 NOR flash designs that observe timing requirements (e.g., 70 ns access, setup/hold margins).
