MX29F040CQI-70G PLCC-32 NOR FLASH SMD IC 11.4×14

Description

MX29F040CQI-70G PLCC-32 NOR FLASH SMD IC The MX29F040CQI-70G is part of Macronix’s MX29F series, known for its compatibility with older systems and robust performance. It is a 4M-bit memory device, organized as 512K x 8 bits, meaning it can store 4 megabits of data, accessible in byte-wide format. It operates on a single 5V power supply, which is used for read, erase, and program operations, making it suitable for legacy designs that still utilize 5V logic, less common in modern systems favoring lower voltages like 3V or 1.8V. The IC is housed in a 32-pin Plastic Leaded Chip Carrier (PLCC) package, which is surface-mount compatible, facilitating easy integration into printed circuit boards PCBs. The package dimensions are approximately 11.43mm x 14.05mm, often rounded to 11.4mm x 14mm in documentation, which is critical for PCB design to ensure proper fit and alignment during assembly.
