概述

Description

MX29LV040CT2I-70G is Macronix’s 4-Mbit, parallel NOR flash memory. It provides an 8-bit data bus, asynchronous random reads, and block/sector erase and program operations. The “040” signifies 4 megabits of storage; LV indicates a low-voltage device (about 2.7–3.6 V); 70G denotes a fast access time (≈70 ns) and RoHS/compliance with the package/grade shown by the suffix. The “CT2I” specifies the package type (likely 8-pin) and industrial-temperature variant. Used for firmware/code storage in embedded systems, boot memory, and firmware updates. For exact pinout, timing diagrams, and command sequences, consult the MX29LV040CT2I-70G datasheet.

Features

Key features of MX29LV040CT2I-70G (Macronix 4Mbit NOR flash, speed grade -70):
- 4 Mbit NOR flash memory (512K x 8)
- 70 ns access time (speed grade -70)
- 5V operation (typical 4.5–5.5 V)
- x8 data bus; parallel NOR flash with asynchronous random access
- Page programming, with sector/block erase and full-chip erase options
- Endurance ~100,000 program/erase cycles; data retention typically >20 years
- Low-power standby/power-down modes
- Industrial temperature range (-40°C to +85°C)
- Standard Macronix parallel flash command set
- Package options: 32-pin package (e.g., SOP/TSOP variants as indicated by CT2I)
Note: Confirm exact sector sizes and package details from the datasheet for your specific board/application.

Package

MX29LV040CT2I-70G comes in a 48-pin TSOP II (Thin Small-Outline Package), RoHS-compliant, 70 ns speed grade.

Pinout

- Pin count: 32 pins (typical for MX29LV040CT2I-70G in a standard TSOP/SOP package)
- Function: 4-Megabit, 8-bit parallel NOR flash memory. Key pins:
- Address inputs: A0–A18
- Data I/O: DQ0–DQ7
- Control: CE# (chip enable, active low), OE# (output enable, active low), WE# (write enable, active low)
- WP# (write protect, optional or can be tied to Vcc)
- Power: Vcc and GND
Note: exact pinout can vary by package variant; the above reflects a typical 32-pin parallel NOR flash configuration.

Manufacturer

- Manufacturer: Macronix International Corp. (MXIC)
- Type of company: Taiwanese semiconductor company that designs and manufactures non-volatile memory chips (NOR flash, ROM, etc.), i.e., a memory IC maker (IDM).

Application

MX29LV040CT2I-70G is a 4-Mbit, 2.7–3.6-V flash memory (70 ns). Applications: boot ROM/firmware storage in embedded controllers; code/data flash for microprocessors/microcontrollers; non-volatile memory in consumer electronics (set-top boxes, DVD players, digital cameras, MP3 players); automotive and industrial control systems (firmware/parameters); networking/telecom equipment requiring reliable on-board flash.

Equivalent

Common drop‑in equivalents (4 Mbit, 3.3V/70ns, 8‑pin NOR flash):
- ST M29W040BB/BP
- Spansion S29GL040D (S29GL040 family)
Optional: Winbond W29GL040 (if available in same package/voltage)
Note: check exact pinout, package, and command set cross‑reference before replacing.
