MX30LF1G18AC-TI

A: The MX30LF1G18AC-TI operates from a single 2.7V to 3.6V power supply and features a 20 ns access time (tR). It supports a 20 ns page program time (tPROG) and a 1 ms block erase time (tBERS). The device is built on SLC NAND technology and includes advanced features such as hardware write protection, read cache functionality, an OTP (One-Time Programmable) area with write protection and locking, built-in software reset capability, and requires external 4-bit ECC (Error Correction Code) per 512 bytes. Key specifications can be found in the table below: Specification Value Memory Density 1 Gbit (128 MB) Memory Organization 128M × 8 bits Supply Voltage 2.7 V to 3.6 V Access Time (tR) 20 ns (max) Page Size 2,048 bytes + 64 bytes spare area Block Size 64 pages per block (128 KB + 4 KB spare) Page Program Time (tPROG) 20 ns (max) Block Erase Time (tBERS) 1 ms (typ) Endurance 100,000 program/erase cycles (minimum) Data Retention 10 years Operating Temperature –40°C to +85°C (industrial grade) Standby Current 80 µA (typical) Package 48-pin TSOP I (12 mm × 18.4 mm) RoHS Status ROHS3 Compliant MSL (Moisture Sensitivity Level) 3 (168 hours)

A: The MX30LF1G18AC-TI uses a standard parallel asynchronous interface. It employs a multiplexed 8-bit I/O bus (I/O0–I/O7) for command, address, and data transfer. The interface consists of the following signals: Signal Function I/O0–I/O7 8-bit bidirectional bus for command, address, and data transfer CLE (Command Latch Enable) When high, commands are latched into the command register ALE (Address Latch Enable) When high, addresses are latched into the address register CE# (Chip Enable) Enables the device when driven low RE# (Read Enable) Enables serial data output during a read cycle WE# (Write Enable) Enables serial data input during a write cycle WP# (Write Protect) Provides hardware protection against accidental program or erase R/B# (Ready/Busy) An open-drain, active-low output that indicates the status of program and erase operations (low = busy) The host controller manages the command, address, and data phases by toggling CLE and ALE to distinguish between commands, addresses, and data on the same 8-bit bus. The WP# (Write Protect) pin provides hardware protection by inhibiting program and erase operations when activated. During program or erase cycles, the R/B# signal goes low and returns high upon completion, signaling the host that the device is ready for the next operation. The device also supports a read cache function for faster sequential page reads.

A: As an SLC NAND Flash device, the MX30LF1G18AC-TI is engineered for long-term reliability and high endurance. Key reliability specifications include: Reliability Parameter Specification Program/Erase Endurance 100,000 cycles (minimum) per block Data Retention 10 years (minimum) Block Erase Time (tBERS) 1 ms (typical) Page Program Time (tPROG) 20 ns (max) Access Time (tR) 20 ns (max) Operating Temperature (Industrial) –40°C to +85°C Read Cache Supports sequential page reads ECC Requirement Host must support 4-bit ECC per 512 bytes These reliability figures meet industry-standard requirements for SLC NAND technology. The device also includes hardware write protection and OTP area write protection with locking, ensuring data integrity in mission-critical systems. The SLC architecture provides superior endurance and data integrity compared to MLC or TLC NAND, making the device suitable for applications that require frequent firmware updates and long-term code storage. Please note that the host controller must provide 4-bit ECC per 512 bytes to achieve the full 100,000 cycle endurance and 10-year data retention specifications.

A: The MX30LF1G18AC-TI is well-suited for a wide range of embedded applications requiring reliable, high-density non-volatile storage with a standard parallel interface. Typical applications include: Industrial control systems – PLCs, HMIs, data loggers, and factory automation equipment. Networking and telecommunications – Routers, switches, base stations, and broadband access devices. Consumer electronics – Smart TVs, set‑top boxes, digital cameras, and portable media devices. Automotive electronics – Infotainment systems, telematics, navigation units, and ADAS (Advanced Driver-Assistance Systems). Medical devices – Diagnostic equipment, patient monitors, and portable instruments. Solid-state storage solutions – Embedded SSDs, USB storage expansion, and memory card controllers. ⚠️ Important Lifecycle Information: The product lifecycle status for the MX30LF1G18AC-TI is Active in terms of manufacturing and availability. However, multiple major distributors, including DigiKey, list the component status as "Not For New Designs" (NRND), indicating it is no longer recommended for new projects. The part is actively stocked by many distributors (e.g., Farnell, Win-Source) with large quantities available, and the manufacturer (Macronix) continues to list the part status as Active with ongoing production. Nevertheless, due to the NRND designation by key distributors, for new designs requiring a 1Gb SLC NAND Flash with parallel interface and industrial temperature range, the following pin-compatible alternatives are recommended: Alternative Part Manufacturer Package Notes MX30LF1G18AC-XKI Macronix TSOP-48 Same family, possibly different temperature or voltage options MT29F1G08ABAEAWP-IT:E Micron Technology TSOP-48 1Gb SLC NAND Flash, industrial temperature, active production S34ML01G200TFI000 SkyHigh Memory TSOP-48 1Gb SLC NAND Flash, 3.3V, industrial temperature, active production W29N01GVSIAA Winbond TSOP-48 1Gb SLC NAND Flash, parallel interface, industrial temperature, active production IS34ML01G081-TLI ISSI TSOP-48 1Gb SLC NAND Flash, industrial temperature, active production For legacy systems already using the MX30LF1G18AC-TI, remaining inventory may still be available through specialist distributors. However, for new designs, qualification of a recommended replacement part is strongly recommended to ensure long-term supply assurance.
