timers, LIN, CAN, USART, SPI, I2C and operates from 3 to 5.5 V.
Figure 9. STM8AF5288T package
The STM8AF5288T automotive 8-bit microcontroller offers 64 Kbytes of non-volatile
memory and integrated true data EEPROM.
The STM8AF52xx series feature a CAN interface.
All devices of the STM8A product line provide the following benefits: reduced system cost,
performance and robustness, short development cycles, and product longevity.
● Reduced system cost
– Integrated true data EEPROM for up to 300 k write/erase cycles
– High system integration level with internal clock oscillators, watchdog and
brownout reset
● Performance and robustness
– Peak performance 20 MIPS at 24 MHz and average performance 10 MIPS at
16 MHz CPU clock frequency
– Robust I/O, independent watchdogs with separate clock source
– Clock security system
● Short development cycles
– Applications scalability across a common family product architecture with
compatible pinout, memory map and modular peripherals.
– Full documentation and a wide choice of development tools
● Product longevity
– Advanced core and peripherals made in a state-of-the art technology
– Native automotive product family operating both at 3.3 V and 5 V supply
The STM8AF and STM8AL boards are supported by the same tools including STVD/STVP
development environment.
