SC16IS752/SC16IS762

Dual UART with I2C-bus/SPI interface, 64-byte FIFOs, IrDA SIR

[1]

Selectable with IOControl register bit 2.

[2]

Selectable with IOControl register bit 1.

[3]

See Section 7.4 “Hardware Reset, Power-On Reset (POR) and Software Reset”.

[4]

HVQFN32 package die supply ground is connected to both VSS pins and exposed center pad. VSS pins must be connected to supply

ground for proper device operation. For enhanced thermal, electrical, and board level performance, the exposed pad needs to be

soldered to the board using a corresponding thermal pad on the board and for proper heat conduction through the board, thermal vias

need to be incorporated in the PCB in the thermal pad region.

[5]

XTAL2 should be left open when XTAL1 is driven by an external clock.

RESET

2

I

Hardware reset (active LOW)[3]

RTSA

1

30

O

UART request to send (active LOW), channel A. A logic 0 on the RTSA

pin indicates the transmitter has data ready and waiting to send. Writing

a logic 1 in the Modem Control Register MCR[1] will set this pin to a

logic 0, indicating data is available. After a reset this pin is set to a logic 1.

This pin only affects the transmit and receive operations when Auto-RTS

function is enabled via the Enhanced Features Register (EFR[6]) for

hardware ﬂow control operation.

RTSB

17

16

O

UART request to send (active LOW), channel B. A logic 0 on the RTSB

pin indicates the transmitter has data ready and waiting to send. Writing

a logic 1 in the Modem Control Register MCR[1] will set this pin to a

logic 0, indicating data is available. After a reset this pin is set to a logic 1.

This pin only affects the transmit and receive operations when Auto-RTS

function is enabled via the Enhanced Features Register (EFR[6]) for

hardware ﬂow control operation.

RXA

1

I

Channel A receiver input. During the local Loopback mode, the RXA

input pin is disabled and TXA data is connected to the UART RXA input

internally.

RXB

24

23

I

Channel B receiver input. During the local Loopback mode, the RXB

input pin is disabled and TXB data is connected to the UART RXB input

internally.

TXA

32

O

Channel A transmitter output. During the local Loopback mode, the TXA

output pin is disabled and TXA data is internally connected to the UART

RXA input.

TXB

23

22

O

Channel B transmitter output. During the local Loopback mode, the TXB

output pin is disabled and TXB data is internally connected to the UART

RXB input.

pad[4]

-

The center pad on the back side of the HVQFN32 package is metallic

and should be connected to ground on the printed-circuit board.

XTAL1

3

I

Crystal input or external clock input. A crystal can be connected between

XTAL1 and XTAL2 to form an internal oscillator circuit (see Figure 11).

Alternatively, an external clock can be connected to this pin.

XTAL2

4

O

Crystal output. (See also XTAL1.) XTAL2 is used as a crystal oscillator

output[5].
