STM8AF5179
Automotive CAN and LIN line 8-bit MCU with 48 Kbytes Flash, 24 MHz CPU, integrated EEPROM-
NRND
The STM8AF52xx, STM8AF62xx, STM8AF51xx, and STM8AF61xx automotive 8-bit microcontrollers described in this datasheet offer from 32 Kbytes to 128 Kbytes of non volatile memory and integrated true data EEPROM. They are referred to as high density STM8A devices in the STM8S and STM8A microcontroller families reference manual (RM0016).
The STM8AF51xx and 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.
The system cost is reduced thanks to an integrated true data EEPROM for up to 300 k write/erase cycles and a high system integration level with internal clock oscillators, wtachdog, and brown-out reset.
Device performance is ensured by 20 MIPS at 24 MHz CPU clock frequency and enhanced characteristics which include robust I/O, independent watchdogs (with a separate clock source), and a clock security system.
Short development cycles are guaranteed due to application scalability across a common family product architecture with compatible pinout, memory map, and modular peripherals. Full documentation is offered with a wide choice of development tools.
Product longevity is ensured in the STM8A family thanks to their advanced core which is made in a state-of-the art technology for automotive applications with 3.3 V to 5.5 V operating supply.
All STM8A and ST7 microcontrollers are supported by the same tools including STVD/STVP development environment, the STice emulator and a low-cost, third party in-circuit debugging tool.
