MICROCHIP ATTINY102F-M7R

The Atmel ATtiny102/ATtiny104 is a low-power CMOS 8-bit microcontroller based on the AVR enhanced RISC architecture. By executing powerful instructions in a single clock cycle, the ATtiny102/ATtiny104 achieves throughputs close to 1 MIPS per MHz. This empowers system designer to optimize the device for power consumption versus processing speed.

The AVR core combines a rich instruction set with 16 general purpose working registers. All the 16 registers are directly connected to the Arithmetic Logic Unit (ALU), allowing two independent registers to be accessed in one 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 provides the following features: 1024 Bytes of In-System Programmable Flash with ReadWhile-Write capabilities, 32 Bytes SRAM, 6/12 general purpose I/O lines for ATtiny102/ATtiny104, 16 general purpose working registers, a 16-bit Timer/Counters (TC) with compare modes, internal and external interrupts, one serial programmable USART, a programmable Watchdog Timer with internal Oscillator and three software selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM, TC, USART, ADC, Analog Comparator (AC), and interrupt system to continue functioning. ADC Noise Reduction mode minimizes switching noise during ADC conversions by stopping the CPU and all I/O modules except the ADC. The Power-down mode saves the register contents but freezes the Oscillator, disabling all other chip functions until the next interrupt or hardware reset.

The device is manufactured using Atmel’s high density Non-Volatile Memory (NVM) technology. The onchip, in-system programmable Flash allows program memory to be re-programmed in-system by a conventional, NVM programmer.

The device 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 kit.
