The BAT32G129 is based on the high-performance ARM^®Cortex-^®M0+ 32-bit RISC core, with an operating temperature range of -40 to 105°C, and a maximum operating frequency of 32MHz. It comes with 256KB Flash, 24KB SRAM, and 2.5KB Data Flash. The product integrates various standard interfaces such as I2C, SPI, UART, and Smart Card Interface (SMCI), and supports C-Type/R-Type LCD drivers. It also includes a 12-bit A/D converter, 8-bit D/A converter, temperature sensor, comparator, and operational amplifier. Additionally, multiple advanced timer modules are integrated, including a 1-channel SysTick timer, 8-channel 16-bit timer, RTC, 1-channel 32-bit timer, and a window watchdog timer.
