Wide Supply
Quad Clock
Quad Throughput
5x6mm Package
Product Overview
The Macronix MX25V1635FZBI is a 16M‑bit (2,097,152 bytes) serial NOR Flash memory designed for low‑power, wide‑voltage applications. Operating from 2.3V to 3.6V, this device is ideal for battery‑powered systems, IoT endpoints, and industrial equipment requiring reliable code storage and data retention. It supports standard SPI, Dual SPI, and Quad SPI modes, with a maximum clock frequency of 80 MHz in Quad I/O mode, providing a read throughput of 320 Mbps.
The device is organized as 8,192 programmable pages of 256 bytes each, with a flexible erase architecture: 4KB sectors, 32KB/64KB blocks, and full chip erase. Housed in a compact 8‑lead WSON (5x6mm) package (ZBI suffix), it operates over the industrial temperature range of -40°C to +85°C, making it suitable for outdoor, automotive aftermarket, and portable medical devices. With 100,000 program/erase cycles and 20‑year data retention, the MX25V1635FZBI delivers the endurance and reliability expected from Macronix’s leading NOR Flash technology.

⚡ Interface Modes & Performance
Compatible with all SPI hosts
Balanced performance
Optimal for XIP
The MX25V1635FZBI supports QPI (Quad Peripheral Interface) mode where all command, address, and data cycles are transmitted over 4 I/O lines, maximizing throughput for high‑end embedded applications.
🔒 Advanced Security & Protection
🔑 Unique 64‑bit Device ID
Each MX25V1635FZBI is factory‑programmed with a unique identifier, enabling device authentication and anti‑counterfeiting measures.
📦 4K‑bit OTP Register
A one‑time programmable area for storing encryption keys, serial numbers, or other sensitive data. Once locked, the OTP region cannot be altered.
🛡️ Flexible Write Protection
The BP0‑BP3 bits define a protected area from 4KB up to the full array. The WP# pin, when enabled, locks the status register, preventing any modification to the protection settings.
⏸️ Suspend/Resume
During a long erase or program cycle, the host can suspend the operation to service a high‑priority read request, then resume later without data loss.
