Product data sheet
The ISP1582 is a high-speed USB peripheral controller. It implements the Hi-Speed USB
or the Original USB physical layer, and the packet protocol layer. It concurrently maintains
up to 16 USB endpoints (control IN, control OUT, and seven IN and seven OUT
configurable) along with endpoint EP0 setup, which accesses the set-up buffer. The

using the external firmware.
For high-bandwidth data transfer, the integrated DMA handler can be invoked to transfer
data to or from external memory or devices. The DMA interface can be configured by
writing to proper DMA registers (see
The ISP1582 supports Hi-Speed USB and Original USB signaling. The USB signaling
speed is automatically detected.
The ISP1582 has 8 kB of internal FIFO memory, which is shared among enabled USB
endpoints, including control IN and control OUT endpoints, and set-up token buffer.
There are seven IN and seven OUT configurable endpoints, and two fixed control
endpoints that are 64 bytes long. Any of the seven IN and seven OUT endpoints can be
separately enabled or disabled. The endpoint type (interrupt, isochronous or bulk) and
packet size of these endpoints can be individually configured, depending on the
requirements of the application. Optional double buffering increases the data throughput
of these data endpoints.
The ISP1582 requires 3.3 V power supply. It has 5 V tolerant I/O pads and an internal
1.8 V regulator to power the digital logic.
