ATMEGA168PA-15MZ

The Microchip Technology ATMEGA168PA-15MZ is an 8-bit AVR microcontroller from the ATmegaPA family, designed for high performance and low power consumption. It features an advanced RISC architecture with 131 instructions, most executed in a single clock cycle, achieving up to 16 MIPS throughput at 16 MHz.

Memory resources include 16 KB of in-system self-programmable Flash, 1 KB of SRAM, and 512 bytes of EEPROM with high endurance (10,000 write/erase cycles for Flash, 100,000 for EEPROM). Peripheral integration is extensive: 23 programmable I/O lines, two 8-bit and one 16-bit timer/counters, six PWM channels, an 8-channel 10-bit ADC with temperature measurement, and serial interfaces (I²C, SPI, UART/USART). An internal calibrated oscillator eliminates the need for external clock components.

The device operates over a supply voltage range of 2.7V to 5.5V (per datasheet) and a temperature range of -40°C to +125°C. Power consumption is optimized for battery-powered applications: 1.4 mA typical in active mode at 4 MHz/3V and 0.8 µA in power-down mode. Six sleep modes provide further energy savings.

Packaged in a 32-lead QFN (5x5 mm) with an exposed pad for efficient thermal dissipation, the ATMEGA168PA-15MZ is suitable for space-constrained designs in industrial control, automotive, and portable consumer electronics.
