Microchip Technology ATmega1609 8-bit Microcontroller

Microchip Technology ATmega1609 8-bit Microcontrollers are based on the 8-bit AVR^® Processor, with a hardware multiplier running at up to 20MHz. The ATmega1609 MCUs feature up to 16KB Flash, 2KB SRAM, and 256 bytes of EEPROM. The On-chip Flash allows the program memory to be reprogrammed in-system through an SPI serial interface, by a conventional nonvolatile memory programmer, or by an On-chip Boot program running on the AVR core. The AVR core offers a flexible, low-power architecture, including Event System and Sleepwalking, accurate Analog features, and Advanced Peripherals.
