TUSB6250 USB 2.0 低功耗高速 ATA/ATAPI 桥接器解决方案
The TUSB6250 is a USB 2.0 HS-capable function controller with an integrated UTMI compliant PHY. The TUSB6250 is intended as a USB 2.0 to ATA/ATAPI bridge for storage devices using a standard ATA or ATAPI interface.
The TUSB6250 is designed to utilize both the fast performance of the state machine and the programmability and flexibility of the embedded microcontroller and firmware. With the elaborative balance between the microcontroller unit (MCU) and the state machine, in addition to its embedded fast MCU (up to 30 MIPS), eight configurable endpoints, up to 40K bytes of configurable code, and data buffer SRAM, the TUSB6250 provides a bridge solution to meet both the performance and flexibility requirement of the next generation external storage devices

TUSB6250 特性
- Universal Serial Bus (USB)
- Fully compliant with USB 2.0 specification: TID #40390418
- 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).
- 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
