1.1 Pin Description

1.1.1 VCC

Supply voltage.

1.1.2 GND

Ground.

1.1.3 Port B (PB5:PB0)

Port B is a 6-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 co ndition becomes active,
even if the clock is not running.

Port B also serves the functions of various special features of the ATtiny13A as listed on page

55.

1.1.4 RESET

Reset input. A low level on this pin for longer than the minimum pulse length will generate a
reset, even if the clock is not running and provided the reset pin has not been disabled. Th e min­imum pulse length is given in Table 18-4 on page 120. Shorter pulses are not guaranteed to
generate a reset.

ATtiny13A

The reset pin can also be used as a (weak) I/O pin.

architecture. By executing powerful instructions in a single clock cycle, the ATtiny13A achieves
throughputs approaching 1 MIPS pe r MHz allow ing the sy stem de signer to op timize po wer con ­sumption versus processing speed.

ATtiny13A

The AVR core combines a rich instruction set with 32 general purpose working registers. All 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 ATtiny13A provides the following feat ures: 1K byte of In -System Programma ble Flash, 64
bytes EEPROM, 64 bytes SRAM, 6 general purpose I/O lines, 32 general purpose working reg­isters, one 8-bit Timer/Counter with compare modes, Internal and External Interrupts, a 4­channel, 10-bit ADC, a programmable Watchdog Timer with internal Oscillator, and three soft­ware selectable power saving modes. The Idle mode stops the CPU while allowing the SRAM,
Timer/Counter, ADC, Analog Comparator, and Interrupt system to continue functioning. The
Power-down mode saves the register contents, disabling all chip functions until the next Inter­rupt or Hardware Reset. The ADC Noise Reduction mode stops the CPU and all I/O modules
except ADC, 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 re-programmed In-System through an SPI
serial interface, by a conventional non-volatile memory programmer or by an On-chip boot code
running on the AVR core.

The ATtiny13A AVR is supported with a full suite of program and system development tools
including: C Compilers, Macro Assemblers, Program Debugger/Simulators, and Evaluation kits.

3.1 Resources

A comprehensive set of drivers, application notes, data sheets and descriptions on development
tools are available for download at http://www.atmel.com/avr.

3.2 Code Examples

This documentation contains simple code examples tha t briefly sh ow how to use var ious par ts of
the device. These code examples assume that the part specific header file is included b efore
compilation. Be aware that not all C compiler vendors include bit definitions in the header files
and interrupt handling in C is compiler dependent. Plea se con firm with th e C com piler d ocumen­tation for more details.

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 85°C or 100 years at 25°C.

Notes: 1. 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.ome 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 operation
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.
