STM8AF6266TCX IC Microcontroller STM8A 8 Bit

STM8AF6266TCX Automotive AEC-Q100 STM8A Microcontroller IC 8-Bit 16MHz 32KB
FLASH 32LQFP
The STM8AF6246, STM8AF6248, STM8AF6266 and STM8AF6268 automotive 8-bit
microcontrollers offer from 16 to 32 Kbyte of Flash program memory and
integrated true data EEPROM. They are referred to as medium density STM8A
devices in STM8S series and STM8AF series 8-bit microcontrollers reference
manual (RM0016).
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, watchdog, and brown-out reset.
Device performance is ensured by a clock frequency of up to 16 MHz CPU 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 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 incircuit debugging tool.
