Product overview

UART mode

● Full duplex, asynchronous communications - NRZ standard format (mark/space)

● High-precision baud rate generator

– A common programmable transmit and receive baud rates up to fMASTER/16

● Programmable data word length (8 or 9 bits) – 1 or 2 stop bits – parity control

● Separate enable bits for transmitter and receiver

● Error detection flags

● Reduced power consumption mode

● Multi-processor communication - enter mute mode if address match does not occur

● Wakeup from mute mode (by idle line detection or address mark detection)

● Two receiver wakeup modes:

– Address bit (MSB)

– Idle line

Input/output specifications

The product features four different I/O types:

● Standard I/O 2 MHz

● Fast I/O up to 10 MHz

● High sink 8 mA, 2 MHz

● True open drain (I2C interface)

To decrease EMI (electromagnetic interference), high sink I/Os have a limited maximum

slew rate. The rise and fall times are similar to those of standard I/Os.

The analog inputs are equipped with a low leakage analog switch. Additionally, the schmitt-

trigger input stage on the analog I/Os can be disabled in order to reduce the device standby

consumption.

STM8A I/Os are designed to withstand current injection. For a negative injection current of

4 mA, the resulting leakage current in the adjacent input does not exceed 1 µA. Thanks to

this feature, external protection diodes against current injection are no longer required.
