Featuring 16 KB Flash, 1 KB SRAM, and 512B EEPROM, it delivers up to 16 MIPS at 16 MHz. Dual USARTs, SPI, JTAG debug interface, 16 PWM channels, and external memory expansion up to 64 KB make it suitable for industrial control, communication gateways, and legacy system upgrades requiring robust serial connectivity.","working_principle":"The ATMEGA162-16AU uses the AVR enhanced RISC architecture with 131 instructions, most executing in a single clock cycle. The 32 general-purpose registers are directly connected to the ALU, allowing two registers to be accessed in one instruction for maximum throughput. The dual USARTs provide independent serial communication channels with hardware buffering, enabling simultaneous communication on two buses. The SPI interface supports high-speed synchronous data transfer with external peripherals. The JTAG interface provides on-chip debugging capabilities and allows Flash programming through the test access port. The external memory interface maps up to 64 KB of external SRAM into the data memory space. The 16-bit timers support input capture, output compare, and PWM generation for motor control applications. Five sleep modes (Idle, ADC Noise Reduction, Power-save, Power-down, Standby) allow fine-grained power management.","pin_description":"\n
