The Microchip ATmega169PA is a low-power CMOS 8-bit microcontroller based on the Microchip AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATmega169PA achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed. single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. The device is manufactured using the Microchip high density non-volatile memory technology. The On-chip In-System re-Programmable (ISP) Flash allows the program memory to be reprogrammed In-System through an SPI serial interface, by a conventional non-volatile memory programmer, or by an On-chip Boot program running on the AVR core. The Boot program can use any interface to download the application program in the Application Flash memory. Software in the Boot Flash section will continue to run while the Application Flash section is updated, providing true Read-While-Write operation. By combining an 8-bit RISC CPU with In-System Self-Programmable Flash on a monolithic chip, the ATmega169PA is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications. The ATmega169PA AVR is supported with a full suite of program and system development tools including: C Compilers, Macro Assemblers, Program Debugger/Simulators, In-Circuit Emulators, and Evaluation kits.
