Product specification
USB smart card reader (OTP or ROM)
TDA8030; TDA8031
8.5.8
A
NALOG INTERFACE
The transceiver interfaces directly to the USB cables
through termination resistors. They are able to transmit
and receive serial data at full speed (12 Mbits/s).
A 1.5 k
pull-up resistor is integrated between pins D+
and V
DDD
and is connected by software by the
microcontroller; in case a
±
5% resistor is preferred, it can
be externally connected between pins DELATT and D+
(DELATT is also controlled by software and is floating
when OFF, or connected to V
DDD
when ON).
8.5.9
S
USPEND MODE
When the USB interface enters Suspend mode, the
software should set the microcontroller in power-down
mode in order to respect the suspend current condition.
The following sequence should be executed:
1.
When the device enters the Suspend mode, it
generates an interrupt on pin INT1
2.
The software should set USB_INT_MASK to logic 1
3.
Then it should wait until CLK_EN_N is HIGH before
entering power-down mode.
When the device detects an activity on the bus, it resets
CLK_EN_N to logic 0 and generates an interrupt on pin
INT1. When leaving the Suspend mode, the following
sequence should be executed:
1.
The software should read the DEVICE_STATUS to
enable the interrupt to be cleared
2.
Reset USB_INT_MASK to logic 0.
