The PA3..0 output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port A pins that are externally pulled low will source current if the pull-up resistors are activated. The Port A pins are tristated when a reset condition becomes active, even if the clock is not running. Port B (PB7:0) Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The Port B output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port B pins that are externally pulled low will source current if the pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes active, even if the clock is not running. Depending on the clock selection fuse settings, PB6 can be used as input to the internal clock operating circuit. The various special features of Port B are elaborated in "Alternate Functions of Port B" on page 64 and "System Clock and Clock Options" on page 25. 1.1.4 1.1.5 Port C (PC7, PC5:0) Port C is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The PC7 and PC5..0 output buffers have symmetrical drive characteristics with both high sink and source capability. As inputs, Port C pins that are externally pulled low will source current if the pull-up resistors are activated. The Port C pins are tri-stated when a reset condition becomes active, even if the clock is not running. PC6/RESET If the RSTDISBL Fuse is programmed, PC6 is used as an I/O pin. Note that the electrical characteristics of PC6 differ from those of the other pins of Port C. If the RSTDISBL Fuse is unprogrammed, PC6 is used as a reset input. A low level on this pin for longer than the minimum pulse width will generate a reset, even if the clock is not running. The minimum pulse length is given in Table 21-3 on page 204. Shorter pulses are not guaranteed to generate a reset. The various special features of Port C are elaborated in "Alternate Functions of Port C" on page 67. 1.1.6 1.1.7 Port D (PD7:0) Port D is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit). The PD7..4 output buffers have symmetrical drive characteristics with both high sink and source capabilities, while the PD3..0 output buffers have stronger sink capabilities. As inputs, Port D 3 8008CS-AVR-03/09 ATtiny48/88 pins that are externally pulled low will source current if the pull-up resistors are activated. The Port D pins are tri-stated when a reset condition becomes active, even if the clock is not running. The various special features of Port D are elaborated in "Alternate Functions of Port D" on page 70. 1.1.8 AVCC AVCC is the supply voltage pin for the A/D converter and a selection of I/O pins. This pin should be externally connected to VCC even if the ADC is not used. If the ADC is used, it is recommended this pin is connected to VCC through a low-pass filter, as described in "Analog Noise Canceling Techniques" on page 166. The following pins receive their supply voltage from AVCC: PC7, PC5:0 and (in 32-lead packages) PA1:0. All other I/O pins take their supply voltage from VCC. 4 8008CS-AVR-03/09 ATtiny48/88 2. Overview 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. 2.1 Block Diagram Figure 2-1.

SPI TWI PORT D (8) PORT B (8) PORT C (8) PORT A (4) RESET CLKI PD[0..7] PB[0..7] PC[0..7] PA[0..3] (in TQFP and MLF) 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. 5 8008CS-AVR-03/09 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 32pad 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 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. 2.2 Comparison Between ATtiny48 and ATTINY88 The ATtiny48 and ATTINY88 differ only in memory sizes. Table 2-1 summarizes the different memory sizes for the two devices. Table 2-1.

Additional Information 3.1 Resources A comprehensive set of development tools, application notes and datasheets are available for download at http://www.atmel.com/avr. 3.2 About Code Examples This documentation contains simple code examples that briefly show how to use various parts of the device. These code examples assume that the part specific header file is included before compilation. Be aware that not all C compiler vendors include bit definitions in the header files and interrupt handling in C is compiler dependent. Please confirm with the C compiler documentation for more details. For I/O Registers located in extended I/O map, "IN", "OUT", "SBIS", "SBIC", "CBI", and "SBI" instructions must be replaced with instructions that allow access to extended I/O. Typically "LDS" and "STS" combined with "SBRS", "SBRC", "SBR", and "CBR". 3.3 Data Retention Reliability Qualification results show that the projected data retention failure rate is much less than 1 PPM over 20 years at 85C or 100 years at 25C. 3.4 Disclaimer Typical values contained in this datasheet are based on simulations and characterization of other AVR microcontrollers manufactured on the same process technology. Min and Max values will be available after the device is characterized. 7 8008CS-AVR-03/09 ATtiny48/88 4.

For compatibility with future devices, reserved bits should be written to zero if accessed. Reserved I/O memory addresses should never be written. 2. I/O Registers within the address range 0x00 - 0x1F are directly bit-accessible using the SBI and CBI instructions. In these registers, the value of single bits can be checked by using the SBIS and SBIC instructions. 3. Some of the Status Flags are cleared by writing a logical one to them. Note that, unlike most other AVRs, the CBI and SBI instructions will only operate on the specified bit, and can therefore be used on registers containing such Status Flags. The CBI and SBI instructions work with registers 0x00 to 0x1F only. 4. When using the I/O specific commands IN and OUT, the I/O addresses 0x00 - 0x3F must be used. When addressing I/O Registers as data space using LD and ST instructions, 0x20 must be added to these addresses. The ATtiny48/88 is a complex microcontroller with more peripheral units than can be supported within the 64 location reserved in Opcode for the IN and OUT instructions. For the Extended I/O space from 0x60 - 0xFF in SRAM, only the ST/STS/STD and LD/LDS/LDD instructions can be used. 11 8008CS-AVR-03/09 ATtiny48/88 5.
