Visão Geral
Description
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.
Equivalent
- Spansion S29GL040 (legacy Cypress Spansion)
- Winbond W29GL040
- SST39VF040 (and SST39VF040B)
Note: check exact packaging/pinout for -T2I-70G and ensure device timing and voltage specs match your design.
Features
- 4 Mbit flash memory (512 KB × 8; or 256 K×16 variants in related parts)
- 70 ns access time
- 5V-only operation; I/O data bus typically x8 (8-bit) with x16 variants available
- Asynchronous read/write; supports page programming (up to 256 bytes per operation)
- Sector/Block erase and full-chip erase options
- Status register and toggle-bit (READY/busy) status for operation monitoring
- Sector/Block protection with software and hardware (lock) mechanisms
- Power-down and low-power standby modes
- Endurance and retention typical of flash (erasable/programmable cycles, data retention ~10 years)
- Industrial temperature variant (-40°C to 85°C) in this G-grade part
- 28-pin package (SOP/TSOP style) suitable for in-system programming
Note: Exact sector sizes and some options may vary by specific device revision; please consult the official datasheet for precise specs.
Pinout
Function: MX29LV040CT2I-70G is a 4‑Mbit parallel NOR flash memory with an 8‑bit data bus (DQ0–DQ7). It uses address lines A0–A18 and control signals CE#, OE#, WE# to perform reads and erase/program operations. It is a non-volatile storage device for firmware/data, powered from Vcc with GND, and configured in a 32‑pin package (typical SOP/TSOP variants).
Manufacturer
- What kind of company: A Taiwanese semiconductor company that designs, manufactures, and markets non-volatile memory products (NOR Flash, NAND Flash, ROM) and other integrated circuits for global electronics customers.
Application
- External program/firmware memory for microprocessors/microcontrollers
- Boot ROM/firmware storage and firmware updates in embedded systems
- Execute-in-place (XIP) memory for embedded CPUs
- Firmware storage in consumer electronics (set-top boxes, printers, multimedia devices)
- Automotive and industrial control units requiring non-volatile code storage (ECUs, controllers)
