Description
Key points:
- Core and memory: 8-bit core with on‑chip flash program memory and RAM (exact sizes vary by variant; see datasheet).
- Peripherals: GPIO, timers and watchdog, ADC, and serial communications (UART, SPI, I2C). Also includes basic analog comparator and power‑management features.
- Power and packaging: supports low‑power modes with wake‑up. The suffix BJ9T6 encodes the specific packaging and temperature range; check the datasheet for details.
- Applications: suitable for automotive body/electronics, consumer appliances, and other small embedded control tasks.
- Development: use ST’s toolchain and programmers (e.g., STVD/Keil/IAR with STVP for in‑circuit programming). For exact specifications, pinout, and memory sizes, consult the official datasheet and reference manual.
Features
- ST7-based 8-bit CPU for simple control tasks
- On-chip Flash program memory and RAM
- General-purpose I/O ports
- Timers with PWM capability (one or more 8/16-bit timers)
- Analog peripherals: ADC and/or analog comparator
- Serial interfaces: USART/UART, I2C, SPI
- Watchdog timer and reset/navigation features
- Clock options: internal RC oscillator and external clock/crystal support
- Low-power modes with wakeup options for energy efficiency
