Memories
The Low density STM8L15x devices have the following main features:
●
●
The EEPROM embeds the error correction code (ECC) feature.
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, I2C1, SPI1, USART1, the three Timers.
Analog-to-digital converter
●
●
●
●
●
●
●
●
ADC1 can be served by DMA1.
Ultralow power comparators
The Low density STM8L15x embeds two comparators (COMP1 and COMP2) sharing the
same current bias and voltage reference. The voltage reference can be internal or external
(coming from an I/O).
●
●
The two comparators can be used together to offer a window function. They can wake up
from Halt mode.
Up to 1 Kbyte of RAM
The non-volatile memory is divided into three arrays:
–
–
–
12-bit analog-to-digital converter (ADC1) with 25 channels (including 1 fast channel),
temperature sensor and internal reference voltage
Conversion time down to 1 µs with f
Programmable resolution
Programmable sampling time
Single and continuous mode of conversion
Scan capability: automatic conversion performed on a selected group of analog inputs
Analog watchdog
Triggered by timer
One comparator with fixed threshold (COMP1).
One comparator rail to rail with fast or slow mode (COMP2). The threshold can be one
of the following:
–
–
Up to 8 Kbytes of low-density embedded Flash program memory
256 bytes of data EEPROM
Option bytes.
External I/O
Internal reference voltage or internal reference voltage submultiple (1/4, 1/2, 3/4)
