Product Summary
The TUSB6250PFC is an USB 2.0 HS-capable function controller with an integrated UTMI compliant PHY. The TUSB6250PFC is intended as a USB 2.0 to ATA/ATAPI bridge for storage devices using a standard ATA or ATAPIinterface. The TUSB6250PFC 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 TUSB6250PFC provides a bridge solution to meet both the performance and flexibility requirement of the next generation external storage devices.
Parametrics
TUSB6250PFC absolute maximum ratings: (1)Supply voltage, VDD: -0.5 V to 4 V; (2)Input voltage, VI, 3.3-V LVCMOS: -0.5 V to VDD + 0.5 V; (3)5-V failsafe TTL compatible LVCMOS: -0.5 V to 6 V; (4)Output voltage, VO, 3.3-V LVCMOS: -0.5 V to VDD + 0.5 V; (5)5-V failsafe TTL compatible LVCMOS: -0.5 V to 6V; (6)Input clamp current, IIK: ±20 mA; (7)Output clamp current, IOK: ±20 mA; (8)Storage temperature range, Tstg: -65℃ to 150℃.
Features
TUSB6250PFC features: (1)Fully compliant with USB 2.0 specification; (2)Integrated USB 2.0 UTMI compliant transceiver (PHY); (3)Supports USB high speed (HS, 480 Mbits/sec) and full speed (FS, 12 Mbits/sec); (4)Supports USB suspend/resume and remote wake-up operation; (5)Supports USB device unique serial number by using on-chip unique die-id; (6)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).
