7.7 Voltage regulator
A 5 V to 3.3 V voltage regulator is integrated on-chip to supply the analog transceiver
and internal logic. This voltage is available at pin V
reg(3.3)
to supply an external 1.5 k
pull-up resistor on the D
+
line. Alternatively, the ISP1181 provides SoftConnect
technology via an integrated 1.5 k
pull-up resistor (see
Section 7.4
).
7.8 PLL clock multiplier
A 6 MHz to 48 MHz clock multiplier Phase-Locked Loop (PLL) is integrated on-chip.
This allows for the use of a low-cost 6 MHz crystal, which also minimizes EMI. No
external components are required for the operation of the PLL.
7.9 Parallel I/O (PIO) and Direct Memory Access (DMA) interface
A generic PIO interface is defined for speed and ease-of-use. It also allows direct
interfacing to most microcontrollers. To a microcontroller, the ISP1181 appears as a
memory device with an 8/16-bit data bus and an 1-bit address bus. The ISP1181
supports both multiplexed and non-multiplexed address and data buses.
The ISP1181 can also be configured as a DMA slave device to allow more efficient
data transfer. One of the 14 endpoint FIFOs may directly transfer data to/from the
local shared memory. The DMA interface can be configured independently from the
PIO interface.

Modes of operation
The ISP1181 has four bus configuration modes, selected via pins BUS_CONF1 and
BUSCONF0:
Mode 0
Mode 1
Mode 2
Mode 3
16-bit I/O port shared with 8-bit or 16-bit DMA port
separate 8-bit I/O port and 8-bit DMA port
8-bit I/O port shared with 8-bit or 16-bit DMA port
reserved.
The bus configurations for each of these modes are given in
Table 3
. Typical interface
circuits for each mode are given in
Section 20.1
.
