Detailed Description
I²C Interface
The DS1086LPMB1 peripheral module can interface to
the host in one of two ways. It can plug directly into a
Pmod-compatible port (configured for I²C) through con-
nector J1, or in this case, other I²C boards can attach to
the same I²C bus through connector J2.
I²C Interface
(Daisy-Chaining Modules)
Alternatively, the peripheral module can connect to other
I²C-based Pmod modules using a 4-conductor ribbon
cable connecting to the J2 connector. In this situation,
pins 1-4 and 5-8 of J2 provide two connections to the I²C
bus, allowing the module to be inserted into an I²C bus
daisy-chain.
Connector J1 provides connection of the module to the
Pmod host. The pin assignments and functions adhere
to the Pmod standard recommended by Digilent. See
Table 1.
The J2 connector allows the module to be connected
through a daisy-chain from another I²C module and/or
provide I²C and power connections to other I²C modules
on the same bus. See Table 2.

PIN SIGNAL
DESCRIPTION
Power-down. When the pin is high, the
1
PDN
output buffer is enabled. When the pin
is low, the master oscillator is disabled
(power-down mode).
Dither enable. When the pin is high, the
2
SPRD dither is enabled. When the pin is low,
the dither is disabled.
3
SCL I²C serial clock
4
SDA I²C serial data
5
GND Ground
6
VCC Power supply
Output enable. When the pin is high,

the output buffer is enabled. When the
pin is low, the output is disabled but the
master oscillator is still on.
