ST72311R, ST72511R, ST72512R, ST72532R 8-bit MCU WITH NESTED INTERRUPTS, EEPROM, ADC, 16-BIT TIMERS, 8-BIT PWM ART, SPI, SCI, CAN INTERFACES
The ST7 family devices ST72311R, ST72511R, ST72512R and ST72532R are 8‑bit microcontrollers with nested interrupt controllers, multiple communication interfaces (SPI, SCI, CAN) and a range of power‑saving modes. They target mid‑range applications, offering program memory from 16 KB to 60 KB, RAM up to 2 KB, and optional EEPROM.
Key sections cover general description, pin‑out, memory maps, clock and reset management, power‑saving modes, I/O port configuration, on‑chip peripherals (watchdog, timers, ADC, PWM‑ART), electrical characteristics, package data and ordering information. The document also includes a summary of changes and legal notices.
