Product details
Overview
SST39VF1602C-70-4I-MAQE from Microchip Technology is a 16 Mbit (1M × 16) CMOS Multi-Purpose Flash Plus (MPF+) memory IC with 70 ns read access time, single 2.7–3.6 V 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. It is used in embedded firmware storage for industrial controllers requiring field-upgradable code with high reliability.
For engineers reviewing the SST39VF1602C-70-4I-MAQE datasheet, SST39VF1602C-70-4I-MAQE pinout, SST39VF1602C-70-4I-MAQE application, or SST39VF1602C-70-4I-MAQE equivalent, this page delivers verified flash memory specifications, JEDEC-compliant x16 interface behavior, top-boot block address mapping (FE000H–FFFFFH), RY/BY# status signaling, and SuperFlash® endurance (100,000 cycles) - all confirmed for the exact MAQE-packaged variant.
Technical Context
The SST39VF1602C-70-4I-MAQE implements SST's proprietary SuperFlash® technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed erase/program times independent of cycle count. Its command-set architecture supports JEDEC-standard x16 flash operations including Word-Program (7 µs typical), Sector-Erase (18 ms), Block-Erase (18 ms), and Chip-Erase (40 ms).
It integrates dual status detection (DQ6 toggle bit and DQ7 data# polling), open-drain RY/BY# output with external pull-up requirement, hardware reset (RST#), and security ID space (128-bit factory + 128-word user). The device enters Auto Low Power mode after valid read, reducing active current from 9 mA to 3 µA without access penalty.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 16 Mbit (1M × 16 organization), supporting 2 MB of firmware or configuration data |
| Read Access Time | 70 ns - enables direct execution from flash (XIP) in 5 MHz–20 MHz microcontroller systems |
| Supply Voltage | 2.7–3.6 V - compatible with 3.3 V logic domains and brown-out tolerant power rails |
| Endurance | 100,000 program/erase cycles - sufficient for >10 years of daily firmware updates in industrial gateways |
| Data Retention | >100 years - ensures long-term validity of stored calibration or security keys without refresh |
| Erase Architecture | Uniform 2 KWord sectors + flexible blocks (one 8 KWord top boot, thirty-one 32 KWord) - supports granular firmware patching |
| Write Protection | Hardware top-block protection (FE000H–FFFFFH) via WP# pin - prevents accidental overwrite of boot loader |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 16-bit address bus (A0–A15) + 4 extended bits (A16–A19); AMS = A19 selects top/bottom boot region |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional bus with internal latching; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select; must be low to enable read/write; controls address/data latch timing |
| OE# | Output Enable | Active-low output gate; determines data bus validity during read; does not affect internal state |
| WE# | Write Enable | Controls write strobe timing; falling edge latches address, rising edge latches data/command |
| WP# | Write Protect | Active-low hardware lock for top 8 KWord boot block (FE000H–FFFFFH); floating = unprotected |
| RST# | Reset | Hardware abort of ongoing erase/program; forces return to read mode within TRP (min 100 ns) |
| RY/BY# | Ready/Busy# | Open-drain status output requiring 10–100 kΩ pull-up; low = busy, high = ready for next command |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; decoupling required per JEDEC layout guidelines |
| VSS | Ground | Reference for all signals; two dedicated pins ensure low-impedance return path |
| NC | No Connection | Unbonded balls (A1, A19, DQ1, DQ3, DQ14 on WFBGA MAQE package); must be left unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows temporary halt of block erase to read/program other sectors - critical for real-time firmware update without system freeze |
| Security ID Space | Factory-programmed 128-bit ID + 128-word user space, lockable to prevent tampering - supports secure boot key binding |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid access - cuts standby power in battery-backed controllers |
| SuperFlash® Fixed Timing | 7 µs word-program and 18 ms sector-erase times remain constant over full 100,000-cycle life - eliminates software de-rating |
| JEDEC x16 Pinout Compliance | Direct drop-in replacement for industry-standard 16-bit parallel flash - no PCB redesign needed for legacy socket migration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar parallel NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C-70-4I-MAQE | Bottom-boot architecture (00000H–01FFFH protected); identical timing, voltage, and package | Used where boot code resides in lowest memory region instead of top | Select only if bottom-boot block alignment matches system bootloader location |
| MX29LV160ETTI-70G | Same density/timing but uses AMD/Fujitsu command set; no RST# pin; different CFI query entry | Lacks hardware reset and erase-suspend; requires software adaptation for status polling | Choose only when migrating legacy designs already using MX29LV family; verify command compatibility |
Compared with SST39VF1601C-70-4I-MAQE and MX29LV160ETTI-70G, the SST39VF1602C-70-4I-MAQE uniquely provides top-boot protection with hardware RST# abort and erase-suspend - enabling safer, more responsive firmware updates in safety-critical embedded systems.

FAQ
What is the exact memory organization and boot block configuration of SST39VF1602C-70-4I-MAQE?
The SST39VF1602C-70-4I-MAQE is organized as 1M × 16 (16 Mbit), with top-boot block protection covering address range FE000H–FFFFFH (8 KWord). This configuration is fixed for the -1602C variant and differs from the bottom-boot SST39VF1601C. The WFBGA MAQE package implements all 48 pins per JEDEC standard, with NC pins explicitly defined in the datasheet.
Does SST39VF1602C-70-4I-MAQE support hardware reset and erase-suspend functionality?
Yes, SST39VF1602C-70-4I-MAQE includes dedicated RST# pin for hardware abort of ongoing erase/program operations, and supports Erase-Suspend/Erase-Resume commands (B0H/30H) to temporarily halt block erases and read/program other sectors - both confirmed in DS20005018B Sections 5.4 and 5.13.
How does the Ready/Busy# (RY/BY#) pin function on SST39VF1602C-70-4I-MAQE?
The RY/BY# pin on SST39VF1602C-70-4I-MAQE is an open-drain output requiring a 10–100 kΩ external pull-up resistor. It drives low during internal Program or Erase operations and goes high (Ready) upon completion. Its status becomes valid after the rising edge of the final WE# pulse in the command sequence.
What are the validated erase and program timing values for SST39VF1602C-70-4I-MAQE?
SST39VF1602C-70-4I-MAQE has validated typical timings: Word-Program = 7 µs, Sector-Erase = 18 ms, Block-Erase = 18 ms, Chip-Erase = 40 ms. These values are fixed across the full endurance life due to SuperFlash® technology and are specified in DS20005018B Section 1.0 Features and Table 6-2 command timing.
Is SST39VF1602C-70-4I-MAQE compatible with JEDEC-standard x16 parallel flash interfaces?
Yes, SST39VF1602C-70-4I-MAQE conforms fully to JEDEC standard pinouts and command sets for x16 memories. It supports standard Read, Word-Program, Sector/Block/Chip-Erase, and Software Data Protection sequences - verified in DS20005018B Sections 2.0 and 6.0, and Table 6-1.
