Description

The ATtiny15L is a low-power CMOS 8-bit microcontroller based on the AVR RISC

architecture. By executing powerful instructions in a single clock cycle, the ATtiny15L

achieves throughputs approaching 1 MIPS per MHz allowing the system designer to

optimize power consumption versus processing speed.

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.

The ATtiny15L provides 1K byte of Flash, 64 bytes EEPROM, six general purpose I/O

lines, 32 general purpose working registers, two 8-bit Timer/Counters, one with high-

speed PWM output, internal oscillators, internal and external interrupts, programmable

Watchdog Timer, 4-channel 10-bit Analog-to-Digital Converter with one differential volt-

age input with optional 20x gain, and three software-selectable Power-saving modes.

The Idle mode stops the CPU while allowing the ADC, analog comparator,

Timer/Counters and interrupt system to continue functioning. The ADC Noise Reduction

mode facilitates high-accuracy ADC measurements by stopping the CPU while allowing

the ADC to continue functioning. The Power-down mode saves the register contents but

freezes the oscillators, disabling all other chip functions until the next interrupt or hard-

ware reset. The wake-up or interrupt on pin change features enable the ATtiny15L to be

highly responsive to external events, still featuring the lowest power consumption while

in the Power-saving modes.

The device is manufactured using Atmel’s high-density, nonvolatile memory technology.

By combining a RISC 8-bit CPU with Flash on a monolithic chip, the ATtiny15L is a pow-

erful microcontroller that provides a highly flexible and cost-efficient solution to many

embedded control applications. The peripheral features make the ATtiny15L particularly

suited for battery chargers, lighting ballasts and all kinds of intelligent sensor

applications.

The ATtiny15L AVR is supported with a full suite of program and system development

tools including macro assemblers, program debugger/simulators, In-circuit emulators

and evaluation kits.

Port B (PB5..PB0)

Port B is a 6-bit I/O port. PB4..0 are I/O pins that can provide internal pull-ups (selected

for each bit). PB5 is input or open-drain output. The use of pin PB5 is defined by a fuse

and the special function associated with this pin is external Reset. The port pins are tri-

stated when a reset condition becomes active, even if the clock is not running.

Port B also accommodates analog I/O pins. The Port B pins with alternate functions are

shown in Table 1.

Analog Pins

Up to four analog inputs can be selected as inputs to Analog-to-Digital Converter (ADC).

Internal Oscillators

The internal oscillator provides a clock rate of nominally 1.6 MHz for the system clock

(CK). Due to large initial variation (0.8 -1.6 MHz) of the internal oscillator, a tuning capa-

bility is built in. Through an 8-bit control register – OSCCAL – the system clock rate can

be tuned with less than 1% steps of the nominal clock.

There is an internal PLL that provides a 16x clock rate locked to the system clock (CK)

for the use of the Peripheral Timer/Counter1. The nominal frequency of this peripheral

clock, PCK, is 25.6 MHz.
