Description
The Digital Interface IC, HCPL-0872 converts the single-
bit data stream from the Isolated Modulator (such as
HCPL-7860/786J/7560) into fifteen-bit output words and
provides a serial output interface that is compatible with
SPI
®
, QSPI
®
, and Microwire
®
protocols, allowing direct
connection to a microcontroller. The Digital Interface IC,
HCPL-0872 is available in a 300-mil wide SO-16 surface-
mount package. Features of the Digital Interface IC
include five different conversion modes, three different
pre-trigger modes, offset calibration, fast over-range
detection, and adjustable threshold detection. Program-
mable features are configured via the Serial Configura-
tion port. A second multiplexed input is available to allow
measurements with a second isolated modulator without
additional hardware.

Because the two inputs are multiplexed, only one con-
version at a time can be made and not all features are
available for the second channel. The available features

Description
Clock input for the Serial Configuration Interface (SCI). Serial Configuration data is clocked in on the
rising edge of CCLK.
Latch input for the Serial Configuration Interface (SCI). The last 8 data bits clocked in on CDAT by
CCLK are latched into the appropriate configuration register on the rising edge of CLAT.
Data input for the Serial Configuration Interface (SCI). Serial configuration data is clocked in MSB
first.
Channel 1 Isolated Modulator clock input. Input Data on MDAT1 is clocked in on the rising edge of
MCLK1.
Channel 1 Isolated Modulator data input.
Channel 2 Isolated Modulator clock input. Input Data on MDAT2 is clocked in on the rising edge of
MCLK2.
Channel 2 Isolated Modulator data input.
Digital ground.
Supply voltage (4.5 V to 5.5 V).
Channel select input. The input level on CHAN determines which channel of data is used during the
next conversion cycle. An input low selects channel 1, a high selects channel 2.
Serial clock input. Serial data is clocked out of SDAT on the falling edge of SCLK.
Serial data output. SDAT changes from high impedance to a logic low output at the start of a conver-
sion cycle. SDAT then goes high to indicate that data is ready to be clocked out. SDAT returns to a
high-impedance state after all data has been clocked out and CS has been brought high. SDAT goes
high immediately after RESET is released.
Conversion start input. Conversion begins on the falling edge of CS. CS should remain low during
the entire conversion cycle and then be brought high to conclude the cycle.
Continuous, programmable-threshold detection for channel 1 input data. A high level output on
THR1 indicates that the magnitude of the channel 1 input signal is beyond a user programmable
threshold level between 160 mV and 310 mV. This signal continuously monitors channel 1 indepen-
dent of the channel select (CHAN) signal.
High speed continuous over-range detection for channel 1 input data. A high level output on OVR1
indicates that the magnitude of the channel 1 input is beyond full-scale. This signal continuously
monitors channel 1 independent of the CHAN signal.
Master reset input. A logic high input for at least 100 ns asynchronously resets all configuration reg-
isters to their default values and zeroes the Offset Calibration registers.
