LCD (Liquid crystal display)

The LCD is only available on STM8L052xx devices.



The liquid crystal display drives up to 4 common terminals and up to 28 segment

terminals to drive up to 112 pixels. Internal step-up converter to guarantee contrast

control whatever VDD.



Static 1/2, 1/3, 1/4 duty supported.



Static 1/2, 1/3 bias supported.



Phase inversion to reduce power consumption and EMI.



Up to 4 pixels which can be programmed to blink.



The LCD controller can operate in Halt mode.

Note:

Unnecessary segments and common pins can be used as general I/O pins.

3.7

Memories

The medium-density value line STM8L052C6 has the following main features:



2 Kbytes of RAM



The non-volatile memory is divided into three arrays:

–

32 Kbytes of medium-density embedded Flash program memory

–

256 bytes of data EEPROM

–

Option bytes

The EEPROM embeds the error correction code (ECC) feature. It supports the read-while-

write (RWW): it is possible to execute the code from the program matrix while

programming/erasing the data matrix.

The option byte protects part of the Flash program memory from write and readout piracy.

3.8

DMA

A 4-channel direct memory access controller (DMA1) offers a memory-to-memory and

peripherals-from/to-memory transfer capability. The 4 channels are shared between the

following IPs with DMA capability: ADC1, I2C1, SPI1, USART1 and the four timers.
