STMicroelectronics ST72561 8-bit MCU Datasheet
The ST72561 is an 8-bit microcontroller designed for mid-range applications requiring CAN and LIN interfaces. It features a common industry-standard 8-bit core with an enhanced instruction set and is available with either High Density Flash (HDFlash) or ROM program memory. The device includes 1 to 2K of RAM and supports up to 60K of program memory depending on the specific variant.
Key peripherals include a 10-bit A/D converter with up to 16 inputs, a PWM Autoreload timer, two general-purpose timers, and communication interfaces such as SPI, LINSCI (Master/Slave or Master-only), and CAN 2.0B active. The microcontroller offers five power-saving modes, including Halt, Auto Wake Up From Halt, Active Halt, Wait, and Slow modes, to optimize power consumption in idle or stand-by states.
