Microchip Technology, Inc. Microcontrollers ATMEGA164A-CUR

The ATmega164A-CUR is an 8-bit microcontroller from Quarktwin Technology Ltd. that operates on a low-power CMOS architecture based on the AVR enhanced RISC design. It is capable of executing 131 powerful instructions in a single clock cycle, achieving throughput of up to 20 MIPS at 20 MHz. The microcontroller features 16 KB of flash memory, 512 bytes of EEPROM, and 1 KB of SRAM, with a write/erase cycle endurance of 10,000 for flash and 100,000 for EEPROM, and data retention of 20 years at 85°C. This device supports various peripherals, including two 8-bit and one 16-bit timer/counter, six PWM channels, and an 8-channel 10-bit ADC with differential mode. Communication interfaces include a 2-wire serial interface (I²C compatible), two USARTs, and an SPI interface. The ATmega164A-CUR also includes a JTAG interface for boundary-scan capabilities and extensive on-chip debugging support. Operating voltage ranges from 1.8V to 5.5V, with power consumption of 0.4 mA in active mode and as low as 0.1 OºA in power-down mode. The microcontroller is available in multiple package types, including 40-pin PDIP and 49-ball VFBGA, making it suitable for various applications. Its features, including support for capacitive touch through the Atmel QTouch library, make it a versatile choice for engineers looking for a reliable microcontroller for their projects.
