PCA9510
Hot swappable I2C-bus and SMBus bus buffer
2
2006 Aug 23
DESCRIPTION
The PCA9510 is a hot swappable I2C-bus and SMBus buffer that
allows I/O card insertion into a live backplane without corrupting the
data and clock buses. Control circuitry prevents the backplane from
being connected to the card until a STOP command or bus idle
occurs on the backplane without bus contention on the card. When
the connection is made, the PCA9510 provides bidirectional
buffering, keeping the backplane and card capacitances isolated.
The PCA9510 has no rise time accelerator circuitry to prevent
interference when there are multiple devices in the same system.
The PCA9510 incorporates a digital ENABLE input pin, which
enables the device when asserted HIGH and forces the device into
a low current mode when asserted LOW, and an open-drain READY
output pin, which indicates that the backplane and card sides are
connected together (HIGH) or not (LOW).
During insertion, the PCA9510 (IN only) SDA and SCL lines are
precharged to 1 V to minimize the current required to charge the
parasitic capacitance of the chip.
The dynamic offset design of the PCA9510/11/12/13/14 I/O drivers
allow them to be connected to another PCA9510/11/12/13/14 device
in series or in parallel and to the A side of the PCA9517. The
PCA9510/11/12/13/14 can not connect to the static offset I/Os used
on the PCA9515/15A/16/16A/17 B side and PCA9518.
APPLICATION
cPCI, VME, AdvancedTCA cards and other multi-point backplane
cards that are required to be inserted or removed from an
operating system.
FEATURES
Bidirectional buffer for SDA and SCL lines increases fanout and
prevents SDA and SCL corruption during live board insertion and
removal from multi-point backplane systems
Compatible with I2C-bus Standard-mode, I2C-bus Fast-mode, and
SMBus standards
Active HIGH ENABLE input
Active HIGH READY open-drain output
High-impedance SDA and SCL pins for V
CC = 0 V
1 V precharge on all SDA and SCL lines (IN only)
