Comparison Between ATtiny48 and ATtiny88
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 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/Coun-
ters, 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 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.
