概要

Description

MX25R4035FZUIH1 is Macronix’s SPI NOR flash memory from the MX25R family. It provides non-volatile storage for embedded systems and firmware.
Key points:
- Density: in the 4-Mbit class (MX25R4035F family).
- Interfaces: supports standard SPI and high-speed modes (Dual/Quad I/O and QPI in capable variants).
- Features: page program, sector/block erase, fast read, low-power modes, and hardware protection/security features.
- Package: 8-pin variant (ZUIH1 code specifies the package).
Electricals:
- Typical operating voltage and temperature ranges follow the datasheet (commonly 2.7–3.6 V for commercial grades; -40 to 85°C or 0–70°C variants).
Typical uses:
- Firmware/code storage, execute-in-place (XIP), boot memory, and data logging in microcontroller and embedded designs.
Note:
- For exact capacity, timing, erase sizes, voltage ranges, and package details, refer to the MX25R4035FZUIH1 datasheet and packaging specification.

Features

MX25R4035FZUIH1 is a Macronix 4-Mbit serial NOR flash. Key features:
- Density: 4 Mbit (512 KB) non-volatile storage
- Voltage: 2.7–3.6 V (industrial grade option often available)
- Interface: SPI with Dual/Quad I/O modes (DQ) and QPI capable in some modes
- Speed: Fast read up to around 104 MHz
- Organization: 256-byte page programming; 4 KB and 64 KB erase blocks; chip erase option
- Endurance/Retention: ~100k P/E cycles; data retention typically ~20 years
- Power: low-power modes including deep power-down
- Security: hardware write-protect regions and status register protections
- Temp range: -40 to 85 °C (industrial)
- Applications: firmware/boot code storage, code protection devices, small embedded storage
Note: exact package/grade options may vary; check datasheet for precise timing, voltages, and protection features.
