3.9.7 Universal asynchronous receivers-transmitters (UARTs)
The STn8810 provides three autobaud UARTs, one of which offers all modem control/status signals.
They are enhanced versions of the industry-standard 16C550 UART with a high data rate up to 3.692
Mbit/s.
3.9.8 USB interface
The STn8810 USB interface is USB 2.0 compliant, with On-The-Go standard extension (rev 1.0)
compliance. The USB-OTG features:
■
Supports full-speed (12 Mbit/s) and low-speed (1.5 Mbit/s) signaling bit rate
■
Supports session request protocol (SRP) and host negotiation protocol (HNP)
■
8 bidirectional endpoints plus control endpoint 0
■
Digital interface to external PHY
■
Fully compatible with STw4810 power manager companion chip
3.9.9 I
2
C bus interface
The STn8810 provides two I©˜C bus interfaces that support the following features:
■
Slave transmitter/receiver and master transmitter/receiver modes
■
Multi-master capability
■
10-bit addressing
■
Standard (100 kHz) and fast (400 kHz) speeds
■
Compliance with I
2
C and DDC standards
In addition to receiving and transmitting data, the interface converts data from serial to parallel format
and vice-versa using an interrupt or polled handshake. The interrupts are enabled and disabled in
software.
3.9.10 MultiMediaCard/secure data card interface (MMC/SD/SDIO)
This interface can directly control one SD card (without encryption/decryption logic) or SDIO card, or
one MultiMediaCard. It also supports several of each card type using the GPIOs for card selection.
