ISP1160BM/01

The ISP1160BM/01 is one member of the ISP1160 family which is designed as the embedded universal serial bus host controller that is well suited for embedded systems and portable devices and can be used in (1)personal digital assistant (PDA); (2)digital camera; (3)third-generation (3-G) phone; (4)set-top box (STB); (5)information appliance (IA); (6)photo printer; (7)MP3 jukebox; (8)game console. And this device provides two downstream ports, and each of the ports has an overcurrent (OC) detection input pin and power supply switching control output pin.

Features of the ISP1160BM/01 are:(1)Maximum 15 Mbyte/s data transfer rate between the microprocessor and the HC; (2)Supports single-cycle and burst mode DMA operations; (3)Built-in FIFO buffer RAM for the HC (4 kbytes); (4)Endpoints with double buffering to increase throughput and ease real-time data transfer for isochronous (ISO) transactions; (5)6 MHz crystal oscillator with integrated PLL for low EMI; (6)Built-in software selectable internal 15 kW pull-down resistors for HC downstream ports; (7)Dedicated pins for suspend sensing output and wake-up control input for flexible applications; (8)Operation at either +5 V or +3.3 V power supply voltage; (9)Operating temperature range from -40 °C to +85 °C; (10)Available in two LQFP64 packages (SOT314-2 and SOT414-1); (11)Complies with Universal Serial Bus Specification Rev. 2.0; (12)Supports data transfer at full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s); (13)Adapted from Open Host Controller Interface Specification for USB Release 1.0a; (14)Selectable one or two downstream ports for HC.

The absolute maximum ratings of the ISP1160BM/01 can be summarized as:(1)supply voltage to pin VCC: -0.5 to +6.0 V;(2)supply voltage to pin VREG: -0.5 to +4.6 V;(3)input voltage: -0.5 to +6.0 V;(4)latch-up current: 100 mA;(5)electrostatic discharge voltage: -2000 to +2000 V;(6)storage temperature: -60 to +150 °C.

The static characteristics of this device can be summarized as:(1)internal regulator output: 3.0 to 3.6 V;(2)operating supply current: 47 mA;(3)suspend supply current: 40 to 500 uA;(4)operating supply current: 50 mA;(5)suspend supply current: 150 to 500 uA;(6)LOW-level input voltage: 0.8 V;(7)HIGH-level input voltage: 2.0 V;(8)positive-going threshold voltage: 1.4 to 1.9 V;(9)negative-going threshold voltage: 0.9 to 4.5 V;(10)hysteresis voltage: 0.4 to 0.7 V.
