The MC9S12UF32 microcontroller unit (MCU) is a 16-bit device composed of standard on-chip peripherals including a 16-bit central processing unit (HCS12 CPU), 32K bytes of Flash EEPROM, and 3.5K bytes of RAM. In addition to the in-chip full-speed USB 2.0 interface, the MC9S12UF32 has built-in the following interfaces and host controllers: ATA-5 interface, compact Flash, secure digital / multimedia, smartmedia, and memory stick. Together with the flexible I/O ports, 8-channel, 16-bit timer, this MCU is well suited for applications such as multi-card readers, USB thumb drives, and USB to external harddisk drives. Available in 100-pin LQFP package. 64-pin LQFP planned for Q3 2004
