概述
Description
MX29LV040CT2I-70G is Macronix’s 4‑Mbit low‑voltage serial NOR flash memory. It’s designed to store firmware and non‑volatile data in embedded systems.
Key points:
- Capacity: 4 Mbit (about 512 KB user space)
- Interface: SPI‑style serial interface (SCK, SI, SO, CS; with optional WP/HOLD pins on some packages)
- Voltage and package: low‑voltage operation (typical 2.7–3.6 V), RoHS‑compliant “G” part; usually in an 8‑pin package
- Performance: around 70 ns read access time (speed grade)
- Features: standard flash commands for read, page/program, sector/erase, and deep power‑down; typical endurance in the NOR‑flash range
- Applications: boot ROMs, firmware storage, and data storage in microcontroller/SoC projects
For exact timing, command set, block sizes, and pinout, consult the MX29LV040CT2I‑70G datasheet.
