Product details
Overview
SST39VF1602C-70-4C-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 hardware top-block protection for boot code storage in embedded microcontroller systems.
For engineers reviewing the SST39VF1602C-70-4C-MAQE datasheet, SST39VF1602C-70-4C-MAQE pinout, SST39VF1602C-70-4C-MAQE application, or SST39VF1602C-70-4C-MAQE equivalent, this page delivers verified package mapping (48-ball WFBGA), JEDEC-compliant x16 interface timing, sector/block/erase capabilities, and real-world flash replacement considerations for industrial control, networking firmware, and automotive ECUs.
Technical Context
The SST39VF1602C-70-4C-MAQE implements SST's proprietary SuperFlash technology with split-gate cells and thick-oxide tunneling injectors, enabling fixed 7 µs word-program and 18 ms sector-erase times independent of cycle count. It supports JEDEC-standard x16 command sets including Software Data Protection (SDP) and Common Flash Interface (CFI) query mode.
Its architecture includes uniform 2 KWord sectors and flexible block sizes (eight 32 KWord, one 16 KWord, two 4 KWord, and one 8 KWord blocks), with top-boot block protection covering FE000H–FFFFFH. The device uses toggle-bit (DQ6/DQ2) and data# polling (DQ7) for write status detection and features RY/BY# open-drain ready/busy signaling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Organization | 1M × 16 (16 Mbit total); enables direct 16-bit bus interfacing with MCUs without data width translation |
| Read Access Time | 70 ns; meets timing requirements for 14 MHz synchronous bus operation in legacy embedded systems |
| Supply Voltage | 2.7–3.6 V; compatible with single-supply 3.3 V logic domains and eliminates need for voltage translators |
| Endurance | 100,000 program/erase cycles; supports field firmware updates over 10+ years in deployed equipment |
| Data Retention | Greater than 100 years; ensures long-term reliability for unpowered archival storage in industrial environments |
| Active Current | 9 mA typical at 5 MHz; reduces thermal load in space-constrained PCB layouts |
| Standby Current | 3 µA typical; enables ultra-low-power sleep modes in battery-backed applications |
Pinout & Package
Package: 48-ball WFBGA (4 mm × 6 mm, 0.5 mm pitch), RoHS-compliant, bottom-side solderable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A0–A19 | Address Inputs | 16-bit address bus (A0–A15) + 4 MSB (A16–A19) for sector/block selection; AMS = A19 per JEDEC x16 standard |
| DQ0–DQ15 | Data I/O | 16-bit bidirectional data bus with internal latching; tri-stated when CE# or OE# high |
| CE# | Chip Enable | Active-low chip select; enables device for read/write when low; high-Z output when high |
| OE# | Output Enable | Active-low output gate; controls data bus drive during read; no effect on write operations |
| WE# | Write Enable | Active-low write strobe; latches address/data on falling/rising edges per JEDEC timing |
| WP# | Write Protect | Hardware top-boot block lock; grounded to protect FE000H–FFFFFH; internally pulled up if floating |
| RST# | Reset | Hardware reset input; forces return to read mode; required TRP low pulse to abort ongoing erase/program |
| RY/BY# | Ready/Busy# | Open-drain status output; low = active erase/program; requires external 10–100 kΩ pull-up |
| VDD | Power Supply | 2.7–3.6 V core and I/O supply; decoupling capacitor required per layout guidelines |
| VSS | Ground | Primary ground reference for all signals; separate VSS pins support low-noise routing |
| NC | No Connection | Unbonded pads (e.g., ball A19, C1, D1, E1, F1, G1, H1, J1, K1, L1); must remain unconnected |
Key Features
| Feature | Design Value |
|---|---|
| Erase-Suspend/Resume | Allows temporary halt of sector/block erase to read or program other locations-critical for real-time firmware patching |
| Auto Low Power Mode | Reduces active read current from 9 mA to 3 µA after valid read; eliminates need for software-controlled power gating |
| Security ID Space | 128-bit factory-programmed SST ID + 128-word user-programmable segment; supports secure boot authentication |
| Uniform Sector Erase | 2 KWord sectors enable fine-grained firmware update partitioning without over-erasing unrelated code sections |
| Flexible Block Architecture | One 8 KWord, two 4 KWord, one 16 KWord, and thirty-one 32 KWord blocks optimize erase granularity for bootloader + application layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SST39VF1601C-70-4C-MAQE | Bottom-boot architecture (00000H–01FFFH protected); identical timing, voltage, and endurance specs | Used where bootloader resides in lowest memory region instead of top; incompatible pin-for-pin due to different protected address map | Select only if bottom-boot protection matches system firmware layout-no PCB change needed but software address mapping differs |
| MX29LV160ETTI-70G | Same 16 Mbit x16 organization, 70 ns access, 2.7–3.6 V, but uses different SDP command set and lacks Security ID feature | Requires modified driver code for erase/program sequences; no hardware-assisted secure ID storage for regulatory traceability | Choose for cost-sensitive designs where CFI compatibility is sufficient and security ID is not required |
Compared with SST39VF1601C-70-4C-MAQE and MX29LV160ETTI-70G, the SST39VF1602C-70-4C-MAQE uniquely combines top-boot hardware protection, integrated Security ID, and SuperFlash's cycle-independent timing-making it optimal for safety-critical firmware storage where both physical layout and cryptographic identity matter.

FAQ
What is the exact memory organization and density of the SST39VF1602C-70-4C-MAQE?
The SST39VF1602C-70-4C-MAQE is organized as 1M × 16, delivering 16 Mbit (2,097,152 bytes) of nonvolatile flash memory. Its address space spans 00000H to FFFFFH, with top-boot block protection covering FE000H–FFFFFH. This configuration supports direct 16-bit parallel bus interfacing without data multiplexing or width conversion circuitry.
Does the SST39VF1602C-70-4C-MAQE support hardware write protection, and how is it implemented?
Yes, the SST39VF1602C-70-4C-MAQE implements hardware top-block protection via the WP# pin. When WP# is grounded, the top 8 KWord block (FE000H–FFFFFH) is locked against program and erase operations. If WP# is left floating, an internal pull-up holds it high, disabling protection. This mechanism operates independently of software commands and remains active during power transitions.
What package type is used for the SST39VF1602C-70-4C-MAQE, and what are its key mechanical dimensions?
The SST39VF1602C-70-4C-MAQE uses a 48-ball WFBGA package measuring 4 mm × 6 mm with 0.5 mm ball pitch. It features a bottom-side solderable footprint optimized for high-density PCB layouts and automated assembly. Pin assignments match Figure 4-3 in DS20005018B, and the package is RoHS-compliant with lead-free terminations.
How does the SST39VF1602C-70-4C-MAQE indicate completion of program or erase operations?
The SST39VF1602C-70-4C-MAQE provides three concurrent status mechanisms: (1) RY/BY# open-drain pin (low = busy), (2) Data# Polling via DQ7 (complement → true data transition), and (3) Toggle Bit on DQ6 (toggling → stable). All methods are valid after defined WE# edge counts per operation type and require no external clock or timer resources.
Is the SST39VF1602C-70-4C-MAQE compatible with JEDEC-standard flash command sets?
Yes, the SST39VF1602C-70-4C-MAQE fully conforms to JEDEC Standard JESD21-C for x16 flash memories. It supports standard command sequences for read, word-program, sector/block/chip-erase, and includes CFI query mode (entry via 555H/AAH/2AAH/55H/555H/98H) for runtime identification of device parameters and command set compliance.
