ATtiny48/88
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 pro-
gram 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 Self-
Programmable 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.
