Features
s Complies with Universal Serial Bus Specification Rev. 2.0
s The Host Controller portion of the ISP1161A1 supports data transfer at full-speed
(12 Mbit/s) and low-speed (1.5 Mbit/s)
s The Device Controller portion of the ISP1161A1 supports data transfer at
full-speed (12 Mbit/s)
s Combines the HC and the DC in a single chip
s On-chip DC complies with most USB device class specifications
s Both the HC and the DC can be accessed by an external microprocessor via
separate I/O port addresses
s Selectable one or two downstream ports for the HC and one upstream port for
the DC
s High-speed parallel interface to most of the generic microprocessors and
Reduced Instruction Set Computer (RISC) processors such as:
x Hitachi® SuperH™ SH-3 and SH-4
x MIPS-based™ RISC
x ARM7™, ARM9™, StrongARM®
s Maximum 15 Mbyte/s data transfer rate between the microprocessor and the HC,
11.1 Mbyte/s data transfer rate between the microprocessor and the DC
s Supports single-cycle and burst mode DMA operations
s Up to 14 programmable USB endpoints with 2 fixed control IN/OUT endpoints for
the DC
s Built-in separate FIFO buffer RAM for the HC (4 kbytes) and DC (2462 bytes)
s Endpoints with double buffering to increase throughput and ease real-time data
transfer for both DC transfers and HC isochronous (ISO) transactions
s 6 MHz crystal oscillator with integrated PLL for low EMI
s Controllable LazyClock (100 kHz
± 50 %) output during ‘suspend’
s Clock output with programmable frequency (3 MHz to 48 MHz)
s Software controlled connection to USB bus (SoftConnect) on upstream port for
the DC
s Good USB connection indicator that blinks with traffic (GoodLink) for the DC
s Software selectable internal 15 k
Ω pull-down resistors for HC downstream ports
s Dedicated pins for suspend sensing output and wake-up control input for flexible
applications
s Global hardware reset input pin and separate internal software reset circuits
for HC and DC
s Operation from a 5 V or a 3.3 V power supply
s Operating temperature range
−40 °Cto +85 °C
s Available in two LQFP64 packages (SOT314-2 and SOT414-1).
