Functional description
The ISP1181 is a full-speed USB interface device with up to 14 configurable
endpoints. It has a fast general-purpose parallel interface for communication with
many types of microcontrollers or microprocessors. It supports different bus
configurations (see
Table 3
) and local DMA transfers of up to 16 bytes per cycle. The
block diagram is given in
Figure 1
.
The ISP1181 has 2462 bytes of internal FIFO memory, which is shared among the
enabled USB endpoints. The type and FIFO size of each endpoint can be individually
configured, depending on the required packet size. Isochronous and bulk endpoints
are double-buffered for increased data throughput. Interrupt IN endpoints can be
configured in rate-feedback mode.
The ISP1181 requires a single supply voltage of 3.0 to 5.5 V and has an internal
3.3 V voltage regulator for powering the analog USB transceiver. It supports
bus-powered operation.
The ISP1181 operates on a 6 MHz oscillator frequency. A programmable clock output
is available up to 48 MHz. During ‘suspend’ state the 24 kHz LazyClock frequency
can be output.
7.1 Analog transceiver
The transceiver is compliant with Universal Serial Bus Specification Rev. 1.1 It
interfaces directly with the USB cable through external termination resistors.

address latch enable input; a HIGH-to-LOW transition latches
the level on pin AD0 as address information in a multiplexed
address/data bus configuration; must be tied LOW (connect
to DGND) for a separate address/data bus configuration

reset input (Schmitt trigger); a LOW level produces an
asynchronous reset; connect to V
