Description

The ATTINY48-AU 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 ATTINY48-AU achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

The AVR core combines a rich instruction set with 32 general purpose working registers. All the 32 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 ATTINY48-AU provides the following features: 4/8K bytes of In-System Programmable Flash,64/64 bytes EEPROM, 256/512 bytes SRAM, 24 general purpose I/O lines (28 I/Os in 32-lead TQFP and 32-pad QFN/MLF packages), 32 general purpose working registers, two flexible Timer/Counters with compare modes, internal and external interrupts, a byte-oriented 2-wire serial interface, an SPI serial port, a 6-channel 10-bit ADC (8 channels in 32-lead TQFP and 32-pad QFN/MLF packages), a programmable Watchdog Timer with internal oscillator, and three software selectable power saving modes. Idle mode stops the CPU while allowing Timer/Counters,2-wire serial interface, SPI port, and interrupt system to continue functioning. Power-down mode saves the register contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset. ADC Noise Reduction mode stops the CPU and all I/O modules except ADC, and helps to minimize switching noise during ADC conversions.

The ATTINY48-AU is supported by a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators and evaluation kits.
