Product Summary

The ISP1161A1BM is a single-chip Universal Serial Bus (USB) Host Controller (HC) and Device Controller (DC). The Host Controller portion of the ISP1161A1BM complies with Universal Serial Bus Specification Rev. 2.0, supporting data transfer at full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s). The ISP1161A1BM Controller portion of the ISP1161A1BD also complies with Universal Serial Bus Specification Rev. 2.0, supporting data transfer at full-speed (12 Mbit/s). These two USB controllers, the HC and the DC, share the same microprocessor bus interface. The ISP1161A1BM has the same data bus, but different I/O locations. The ISP1161A1BD also has separate interrupt request output pins, separate DMA channels that include separate DMA request output pins and DMA acknowledge input pins. This makes it possible for a microprocessor to control both the USB HC and the USB DC at the same time.

Parametrics

ISP1161A1BM absolute maximum ratings: (1) VCC(5V) supply voltage on pin VCC: -0.5, +6.0 V; (2) VCC(3.3V) supply voltage on pin Vreg(3.3): -0.5, +4.6 V; (3) VI input voltage: -0.5, +6.0 V; (4) Ilu latch-up current VI < 0 or VI > VCC: 100 mA; (5) Vesd electrostatic discharge voltage ILI < 1 mA [1]: -2000, +2000 V; (6) Tstg storage temperature: -60, +150 °C.
