Comparison Between ATtiny48 and ATtiny88
ATtiny48/88
The ATtiny48/88 provides the following features:
The device includes the following modes for saving power:
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.
The ATtiny48 and ATtiny88 differ only in memory sizes, as summarised in
Table 2-1.
Device
ATtiny48
ATtiny88
• 4/8K bytes of In-System Programmable Flash
• 64/64 bytes EEPROM
• 256/512 bytes SRAM
• 24 general purpose I/O lines
• 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
• A programmable Watchdog Timer with internal oscillator
• Three software selectable power saving modes.
• Idle mode: stops the CPU while allowing the timer/counter, ADC, analog comparator, SPI,
• ADC Noise Reduction mode: minimizes switching noise during ADC conversions by stopping
• Power-down mode: registers keep their contents and all chip functions are disabled until the
TWI, and interrupt system to continue functioning
the CPU and all I/O modules except the ADC
next interrupt or hardware reset
