PCA9512A; PCA9512B

Level shifting hot swappable I

C-bus and SMBus bus buffer

Rev. 6 — 1 March 2013

Product data sheet

1. General description

The PCA9512A/B is a hot swappable I

C-bus and SMBus buffer that allows I/O card

insertion into a live backplane without corruption of the data and clock buses and includes

two dedicated supply voltage pins to provide level shifting between 3.3 V and 5 V systems

while maintaining the best noise margin for each voltage level. Either pin may be powered

with supply voltages ranging from 2.7 V to 5.5 V with no constraints on which supply

voltage is higher. Control circuitry prevents the backplane from being connected to the

card until a stop bit or bus idle occurs on the backplane without bus contention on the

card. When the connection is made, the PCA9512A/B provides bidirectional buffering,

keeping the backplane and card capacitances isolated.

Both the PCA9512A and PCA9512B use identical silicon (PCN201012007F dated

13 Dec 2010), so the PCA9512B will be discontinued in the near future and is not

recommended for new designs.

The PCA9512A/B rise time accelerator circuitry allows the use of weaker DC pull-up

currents while still meeting rise time requirements. The PCA9512A/B incorporates a digital

input pin that enables and disables the rise time accelerators on all four SDAn and SCLn

pins.

During insertion, the PCA9512A/B SDAn and SCLn pins are precharged to 1 V to

minimize the current required to charge the parasitic capacitance of the chip.

The incremental offset design of the PCA9510A/11A/12A/12B/13A/14A I/O drivers allows

them to be connected to another PCA9510A/11A/12A/12B/13A/14A device in series or in

parallel and to the I

C compliant side of static offset bus buffers, but not to the static offset

side of those bus buffers.

2. Features and benefits



Bidirectional buffer for SDA and SCL lines increases fan-out and prevents SDA and

SCL corruption during live board insertion and removal from multipoint backplane

systems



Compatible with I

C-bus Standard mode, I

C-bus Fast mode, and SMBus standards



Built-in

V/t

rise time accelerators on all SDA and SCL lines (0.6 V threshold) with

ability to disable

V/t

rise time accelerator through the ACC pin for lightly loaded

systems, requires the bus pull-up voltage and respective supply voltage (V

or V

CC2

)

to be the same



5 V to 3.3 V level translation with optimum noise margin



High-impedance SDAn and SCLn pins for V

or V

CC2

= 0 V



1 V precharge on all SDAn and SCLn pins



Supports clock stretching and multiple master arbitration and synchronization
