MC9S12UF32 enables high-speed USB 2.0 communications and controls compact flash memories, multimedia cards and smart media cards
The MC9S12UF32 16-bit, flash-based microcontroller from Freescale Semiconductor, a wholly owned subsidiary of Motorola Inc., is now available to help designers bring an improved level of peripheral functionality to the personal computer.
The MC9S12UF32 microcontroller features an integrated universal serial bus (USB) 2.0 physical layer transceiver to provide comprehensive USB specification implementation for both full-speed (12 Mbps) and high-speed (480 Mbps) operation. The high-speed operation, running at bus speeds of up to 30 megahertz, implements fast large data transfers for applications such as real-time movies that were impractical at the previous lower-speed operation.
Besides standard USB functionality, the MC9S12UF32 enables control of external hard disk drives, CD-ROM and DVD-ROM drives via the USB 2.0 protocol. The device also enables compact flash memory devices: secure digital memory cards, multimedia cards, smart media memory cards and memory stick memory cards.
The availability of up to 75 programmable I/O lines helps to minimize the PC system costs and enhance flexibility.
The MC9S12UF32 is designed to reduce the device count in a PC system and improves performance by off-loading peripheral overhead functions from the CPU. The on-board flash enables the peripheral system to accommodate future software changes. The MC9S12UF32 can also be used to enable card readers for popular flash memory cards, ATA (IBM PC/AT attachment) bridges for external hard disks, USB flash disks and digital wallets.
