ATMEGA169P-16AU

The ATMEGA169P-16AU is an 8-bit AVR microcontroller from Microchip Technology featuring a high-performance RISC architecture. It offers 16KB of in-system self-programmable Flash memory, 1KB SRAM, and 512B EEPROM with high endurance (10,000 Flash/100,000 EEPROM write/erase cycles) and data retention of 20 years at 85°C or 100 years at 25°C. The device operates at speeds up to 16 MHz, delivering up to 16 MIPS throughput. It includes a rich set of peripherals: a 4x25 segment LCD driver, two 8-bit and one 16-bit timer/counters, four PWM channels, an 8-channel 10-bit ADC, and multiple serial interfaces (SPI, USART, USI). Additional features include brown-out detection, power-on reset, programmable watchdog timer, and five sleep modes for power optimization. The microcontroller is supplied in a 64-lead TQFP package (14x14mm) and supports a supply voltage range of 2.7V to 5.5V. It is designed for surface mount assembly and operates over an industrial temperature range of -40°C to 85°C. Connectivity options include SPI, UART/USART, and USI, making it suitable for embedded control applications requiring LCD interfacing and mixed-signal processing.
