NAND Flash Memory Controller
The ML54053 is a controller that integrates into a single chip a host interface that conforms to PCMCIA, the necessary functions to control NAND memory, and a microcontroller.
Internal 256 byte RAM is provided for storage of the card information structure (CIS).
A maximum of 4 chips of 64 Mbit or larger NAND flash memory can be controlled.
FEATURES
• Single chip controller with internal microcontroller (min. 4 cycles/instruction execution)
• Operating voltage: 3.3 V, Interface voltage: 3.3 V/5 V
• Internal 256B RAM for card information structure (CIS) storage
• Conforms to CompactFlash specification
• Auto-sleep mode support
• True IDE Mode support
• ECC system by BCH code (3-bit random error correction is possible for user data and ECC data)
• Substitute control function (defect management function)
• Debug mode support
• High-speed operation via dual port bus control
• Low power consumption due to single chip controller
• Control of four NAND flash memories (64MB to 512MB) is possible
• 120-pin TQFP package (TQFP120-P-1414-0.40-K)
