10 / 124 page  Main Features 2−1 SLLS535A − January 2004 TUSB6250 2 Main Features 2.1 Universal Serial Bus (USB) • Fully compliant with USB 2.0 specification • Integrated USB 2.0 UTMI compliant transceiver (PHY) • Supports USB high speed (HS, 480 Mbits/sec) and full speed (FS, 12 Mbits/sec) • Supports USB suspend/resume and remote wake-up operation • Supports USB device unique serial number by using on-chip unique die-id • Supports eight configurable endpoints (four input and four output) with a user-programmable buffer size, in addition to the default control endpoint (endpoint 0): − Each endpoint can be configured for interrupt and bulk (double buffered) transfers. − All endpoints share the 4K byte data buffer implemented in the SPRAM (single port SRAM). 2.2 Microcontroller Unit (MCU) • Integrated 60-MHz 8051 microcontroller with two clocks per cycle (up to 30 MIPS) • Application code is loadable from either the USB host or the external EEPROM (via the I2C interface) • 8K bytes of ROM for the boot loader • 1152 bytes of RAM with multiple bank selectable capability for the internal data buffer (IDATA space) • 40K bytes of RAM, configurable for either code or data space, which provides flexibility to the end product application: − 32K byte code RAM with 8K byte sector buffer data space − 16K byte code RAM with 24K byte sector buffer data space − 8K byte code RAM with 32K byte sector buffer data space • Master I2C interface controller for external device accesses capable of 100 Kbits/sec or 400 Kbits/sec transfer speed. • Up to 13 GPIOs and three general-purpose open-drain outputs can be used for end product specific functions. 2.3 ATA/ATAPI Interface Controller • Supports USB mass storage device class specification bulk-only transfer protocol • Glueless interface to ATA and ATAPI drives with full ATA and ATAPI protocol support • High-performance DMA engine supports all PIO, multiword DMA, and UDMA transfer modes up to UDMA mode 4 (UDMA-66 or ATA-66). • Correctly handles all 13 cases in bulk-only transfer protocol under all supported transfer modes. • Fully programmable ATA/ATAPI interface access timing • Provides multiple flexible transfer options to achieve both high-speed transfer by the state machine and high flexibility with MCU involvement: − Fully-manual transfer (both command and data) by the MCU − Semi-auto transfer with command transfer by the MCU and data transfer by the state machine − High-performance fully-auto data transfer mainly by the state machine with few MCU involvements. • Supports mass-storage devices compatible with the ATA/ATAPI-5 specification: − Hard-disk drive − DVD/CD−ROM |
