Product details
Overview
SST39LF802C-55-4C-MAQE from Microchip Technology is a 8 Mbit (512K × 16) low-voltage Multi-Purpose Flash Plus memory IC with 55 ns read access time, 3.0–3.6 V single-supply operation, and top-boot block protection. It features uniform 2 KWord sector erase, flexible block architecture (including one 8 KWord top boot block), and hardware write protection via WP# pin. Used in embedded firmware storage for industrial controllers requiring fast, reliable nonvolatile code retention.
For engineers reviewing the SST39LF802C-55-4C-MAQE datasheet, SST39LF802C-55-4C-MAQE pinout, SST39LF802C-55-4C-MAQE application, or SST39LF802C-55-4C-MAQE equivalent, key selection criteria include boot-block configuration (top vs bottom), 55 ns read timing, 3.0–3.6 V operating range, TSOP-48 package compatibility, and SuperFlash® endurance (100,000 cycles).
Technical Context
This device implements SST's proprietary SuperFlash® technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. It supports JEDEC-standard x16 flash command sets including Word-Program, Sector-Erase (50H), Block-Erase (30H), Chip-Erase (10H), and Erase-Suspend (B0H).
It integrates dual status detection-Data# Polling (DQ7) and Toggle Bits (DQ6/DQ2)-plus open-drain RY/BY# output for real-time operation monitoring. Hardware reset (RST#) and dedicated WP# pin provide deterministic recovery and top-boot block protection (7E000H–7FFFFH), distinguishing it from bottom-boot variants like SST39LF801C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 Mbit (512K × 16 organization), supporting 16-bit parallel data bus interface |
| Read Access Time | 55 ns typical - enables direct execution from flash in 20–25 MHz microcontroller systems |
| Supply Voltage | 3.0–3.6 V - compatible with 3.3 V logic domains without level-shifting |
| Endurance | 100,000 program/erase cycles - sufficient for field firmware updates over 10+ years |
| Data Retention | Greater than 100 years - ensures long-term reliability in unpowered storage |

| Write Protection | Hardware top-boot block protection (7E000H–7FFFFH) activated by WP# low - prevents accidental overwrite of boot code |
Pinout & Package
Package: 48-lead TSOP (12 mm × 20 mm), RoHS-compliant, surface-mountable with standard JEDEC x16 flash pinout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A18 | Address Inputs | 19-bit address bus; AMS = A18 selects top/bottom boot block during erase operations |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus; latched internally during writes; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write operations |
| OE# | Output Enable | Active-low output gate; controls data bus drive during reads only |
| WE# | Write Enable | Active-low control for write cycles; latches address/data on falling/rising edges per JEDEC timing |
| WP# | Write Protect | Active-low hardware lock for top 8 KWord boot block (7E000H–7FFFFH) |
| RST# | Reset | Active-low hardware reset; forces device into Read mode, terminating in-progress operations |
| RY/BY# | Ready/Busy# | Open-drain status indicator; pulled low during Program/Erase; requires external 10–100 kΩ pull-up |
| VDD | Power Supply | 3.0–3.6 V supply; powers core logic and SuperFlash® array |
| VSS | Ground | Reference ground for all I/O and core functions |
| NC | No Connection | Unbonded pins (e.g., A13, A9, A12 in TSOP); must remain unconnected |
Key Features
| Feature | Design Value |

| Top Boot Block Protection | Hardware-enforced 8 KWord (7E000H–7FFFFH) protection via WP# pin - eliminates need for software-based lock bits |
| Erase-Suspend/Resume | Allows temporary halt of Block/Sector-Erase to read or program other regions - critical for real-time firmware update safety |
| Security ID Space | Factory-programmed 128-bit ID + 128-word user space - supports secure device authentication and traceability |
| Auto Low Power Mode | Reduces active read current from 5 mA to 3 µA after valid access - cuts standby power in always-on embedded systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF802C-70-4C-MAQE | 70 ns read access time; 2.7–3.6 V supply range - wider voltage tolerance but slower timing | Preferred for legacy 2.7 V systems or cost-sensitive designs where 55 ns is not required | Select when board-level voltage margin includes 2.7 V and timing budget allows ≥70 ns access |
| MX29LV800CTTI-70G | 70 ns access; 3.0–3.6 V; bottom-boot configuration (00000H–01FFFH); no RST# pin | Lacks hardware reset and top-boot layout - unsuitable for bootloader-critical applications requiring RST#-initiated recovery | Choose only if bottom-boot architecture aligns with existing firmware partitioning and RST# is unused |
Compared with SST39LF802C-55-4C-MAQE, the SST39VF802C variant offers broader voltage flexibility at speed cost, while the MX29LV800CTTI lacks top-boot protection and reset functionality - making SST39LF802C-55-4C-MAQE uniquely suited for safety-critical boot code storage requiring deterministic hardware lock and recovery.

FAQ
What is the boot block configuration of SST39LF802C-55-4C-MAQE?
The SST39LF802C-55-4C-MAQE implements top-boot block protection, covering the 8 KWord address range 7E000H–7FFFFH. This is hardware-enforced via the WP# pin and distinguishes it from bottom-boot variants like SST39LF801C. The top-boot layout ensures bootloader integrity during firmware updates, and this configuration is fixed per the device ID (233AH) confirmed in the datasheet.
Does SST39LF802C-55-4C-MAQE require an external VPP voltage?
No, SST39LF802C-55-4C-MAQE does not require an external VPP voltage. It uses internal VPP generation for erase and program operations, powered solely by the 3.0–3.6 V VDD supply. This eliminates the need for auxiliary high-voltage circuitry and simplifies board design - a key advantage of SST's SuperFlash® architecture over older flash technologies.
How is write operation completion detected on SST39LF802C-55-4C-MAQE?
SST39LF802C-55-4C-MAQE supports three complementary methods: Data# Polling (DQ7 toggles until completion), Toggle Bits (DQ6 toggles during operation), and Ready/Busy# (RY/BY# open-drain output pulled low during active erase/program). All are valid simultaneously; RY/BY# requires an external 10–100 kΩ pull-up resistor to function correctly.
What package type is used for SST39LF802C-55-4C-MAQE?
SST39LF802C-55-4C-MAQE is packaged in a 48-lead TSOP (Thin Small Outline Package), 12 mm × 20 mm footprint, with standard JEDEC x16 flash pinout. The "MAQE" suffix explicitly denotes this TSOP-48 variant, distinct from TFBGA or WFBGA versions of the same family.
Is SST39LF802C-55-4C-MAQE compatible with JEDEC-standard flash command sets?
Yes, SST39LF802C-55-4C-MAQE fully conforms to JEDEC-standard pinouts and command sets for x16 flash memories. It supports industry-standard sequences for Word-Program, Sector-Erase (50H), Block-Erase (30H), Chip-Erase (10H), and Erase-Suspend (B0H), ensuring drop-in compatibility with existing flash controller firmware designed for JEDEC-compliant devices.
