Visão Geral
Description
- 16 KB Flash memory, 768 B RAM, and 1 KB EEPROM.
- Max 64 MHz clock speed (16 MIPS with 4x PLL).
- 35 I/O pins, supporting digital, analog (13-channel 10-bit ADC), and PWM.
- Peripherals: USART, SPI, I²C, timers, and comparators.
- Low-power modes (down to 100 nA in sleep).
- Operating voltage: 2.0V–5.5V, making it versatile for battery-powered apps.
- 40-pin TQFP (PT) package, suitable for compact designs.
Ideal for embedded systems, automation, and IoT due to its balance of performance, power efficiency, and peripheral integration.
