ST92163 - GENERAL DESCRIPTION

INTRODUCTION (Cont’d)

1.1.5 On-chip Peripherals

USB Interface

The USB interface provides a full speed USB 1.1

compliant port with embedded transceiver and

voltage regulator. Up to 16 endpoints are available

supporting up to 8 USB devices. Separate transmit

and receive DMA channels are available for each

device for fast data transfers with internal RAM.

Parallel I/O Ports

The ST9 is provided with dedicated lines for input/

output. These lines, grouped into 8-bit ports, can

be independently programmed to provide parallel

input/output or to carry input/output signals to or

from the on-chip peripherals and core. All ports

have active pull-ups and pull-down resistors com-

patible with TTL loads. In addition pull-ups can be

turned off for open drain operation and weak pull-

ups can be turned on to save chip resistive pull-

ups. Input buffers can be either TTL or CMOS

compatible.

High Current (10 mA) outputs are available for

driving external devices such as LEDs.

Multifunction Timer

The Multifunction Timer has a 16-bit Up/Down

counter supported by two 16-bit compare regis-

ters, two 16-bit input capture registers and two

DMA channels. Timing resolution can be pro-

grammed using an 8-bit prescaler. 12 operating

modes allow a range of different timing functions

to be easily performed such as complex waveform

generatation, measurement or PWM output.

16-bit Timer/Watchdog

The Timer/Watchdog peripheral can be used as a

watchdog or for a wide range of other timing func-

tions such as generating periodic interrupts, meas-

uring input signal pulse widths, requesting an in-

terrupt after a set number of events. It can also

generate a square wave or PWM output signal.

Serial Communications Controller

The SCI provides a synchronous or asynchronous

serial I/O port using two DMA channels. Baud

rates and data formats are programmable. Con-

troller applications can further benefit from the self

test and address wake-up facility offered by the

character search mode.

I2C Bus Interface

The I2C bus is a synchronous serial bus for con-

necting multiple devices using a data line and a

clock line. Multimaster and slave modes are sup-

ported. Data transfer between the bus and memo-

ry is performed by DMA. The I2C interface sup-

ports 7 and 10-bit addressing. It operates in multi-

master or slave mode and supports speeds of up

to 400 KHz. Bus events (Bus busy, slave address

recognized) and error conditions are automatically

flagged in peripheral registers and interrupts are

optionally generated.

Analog/Digital Converter

The ADC provides up to 6 analog inputs with on-

chip sample and hold, fast conversion time and 8-

bit resolution. Conversion can be triggered by a

signal from the Multifunction Timer (MFT).
