Product Introduction
The ATtiny48/88 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 ATtiny48/88 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 ATtiny48/88 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 in 32-lead TQFP, 32-pad QFN, and 32-ball UFBGA 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 in 32-lead TQFP, 32-pad QFN, and 32-ball UFBGA packages
• A programmable Watchdog Timer with internal oscillator
• Three software selectable power saving modes.
The device includes the following modes for saving power:
• Idle mode: stops the CPU while allowing the timer/counter, ADC, analog comparator, SPI, TWI, 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
• Power-down mode: registers keep their contents and all chip functions are disabled until the next interrupt or hardware reset
The device is manufactured using Atmel’s high density non-volatile memory technology. The On-chip 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 Flash memory. By combining an 8-bit RISC CPU with In-System SelfProgrammable Flash on a monolithic chip, the Atmel ATtiny48/88 is a powerful microcontroller that provides a highly flexible and cost effective solution to many embedded control applications.
The ATtiny48/88 AVR is supported by a full suite of program and system development tools including: C compilers, macro assemblers, program debugger/simulators and evaluation kits.
