Philips Electronics 

Philips Semiconductors

ISP1161A1

USB single-chip host and device controller

2. 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 kΩ 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 °C to +85 °C

s Available in two LQFP64 packages (SOT314-2 and SOT414-1).
