LCD (Liquid crystal display)
The liquid crystal display drives up to 8 common terminals and up to 40 segment terminals
to drive up to 320 pixels. It can also be configured to drive up to 4 common and 44 segments
(up to 176 pixels).

Unnecessary segments and common pins can be used as general I/O pins.
Memories
The high density STM8L162xx devices have the following main features:
●
●
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.
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, DAC1,DAC2, AES, I2C1, SPI1, SPI2, USART1,
USART2, USART3, and the 5 Timers.
Internal step-up converter to guarantee contrast control whatever V
Static 1/2, 1/3, 1/4, 1/8 duty supported.
Static 1/2, 1/3, 1/4 bias supported.
Phase inversion to reduce power consumption and EMI.
Up to 8 pixels which can programmed to blink.
The LCD controller can operate in Halt mode.
4 Kbytes of RAM
The non-volatile memory is divided into three arrays:
–
–
–
64 Kbytes of medium-density embedded Flash program memory
2 Kbytes of Data EEPROM
Option bytes.
