MX35LF2G24AD-Z4I

MX35LF2G24AD-Z4I is Macronix’s 2-Gbit Serial NOR Flash memory (MX35LF family). It provides nonvolatile storage for embedded systems and firmware.
Key points
- Capacity: 2 Gbit (256 MB) of flash.
- Interface: SPI-compatible serial interface with support for higher-speed multi‑IO modes in some variants.
- Voltage/grade: low‑voltage operation; exact Vcc range and temperature grade depend on the specific “Z4I” variant (industrial grade typically -40°C to some upper limit).
- Addressing: uses standard 3‑byte addressing in basic mode and 4‑byte addressing for full density.
- Memory organization: pages (e.g., 256 bytes), sectors (commonly 4 KB) and larger blocks; supports page program and sector/block erase.
- Features: fast read, power-down/deep-power-down, status registers, write protection, and suspend/resume of operations in many configurations.
- Package: compact 8‑pin form factor (suffix “Z4I” indicates a specific package/temperature option).
Typical uses: boot/firmware storage for MCUs, code/data storage in embedded/industrial applications.
For exact timing, voltage, commands, and endurance, consult the official datasheet for MX35LF2G24AD-Z4I.

Here are the typical features of the MX35LF2G24AD-Z4I (Macronix 2Gbit serial Flash):
- Density: 2 Gbit (256 MB) non-volatile memory
- Interface: Serial Quad I/O (SQI/Quad SPI) with Dual I/O and standard SPI compatibility
- Speed: High-speed operation (read up to around 100–104 MHz range depending on mode)
- Voltage: Vcc across common SPI ranges (generally around 2.7–3.6 V; variant specifics may include 1.8 V options in related parts)
- Memory organization: 4 KB sectors; 64 KB blocks (typical NOR-like sectoring)
- Endurance/Retention: High endurance for NOR-type flash; long data retention
- Security: Block protection, protection registers, and write protection features
- ECC/Reliability: Hardware ECC support for data integrity
- Low power: Various power-saving modes
- Temp range: Industrial grade (-40°C to 85°C)
- Packaging: Small-footprint serial flash package (common 8-pin or similar)
Note: exact voltage ranges, block sizes, and speeds can vary by revision; consult the official datasheet for precise specs.

8-pin SOP (SOP-8) package (8-lead small-outline package).
