ATtiny26(L)

Description

The ATtiny26(L) 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 ATtiny26(L) achieves

throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power con-

sumption 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 con-

ventional CISC microcontrollers. The ATtiny26(L) has a high precision ADC with up to 11 single

ended channels and 8 differential channels. Seven differential channels have an optional gain of

20x. Four out of the seven differential channels, which have the optional gain, can be used at the

same time. The ATtiny26(L) also has a high frequency 8-bit PWM module with two independent

outputs. Two of the PWM outputs have inverted non-overlapping output pins ideal for synchro-

nous rectification. The Universal Serial Interface of the ATtiny26(L) allows efficient software

implementation of TWI (Two-wire Serial Interface) or SM-bus interface. These features allow for

highly integrated battery charger and lighting ballast applications, low-end thermostats, and

firedetectors, among other applications.

The ATtiny26(L) provides 2K bytes of Flash, 128 bytes EEPROM, 128 bytes SRAM, up to 16

general purpose I/O lines, 32 general purpose working registers, two 8-bit Timer/Counters, one

with PWM outputs, internal and external Oscillators, internal and external interrupts, program-

mable Watchdog Timer, 11-channel, 10-bit Analog to Digital Converter with two differential

voltage input gain stages, and four software selectable power saving modes. The Idle mode

stops the CPU while allowing the Timer/Counters and interrupt system to continue functioning.

The ATtiny26(L) also has a dedicated ADC Noise Reduction mode for reducing the noise in ADC

conversion. In this sleep mode, only the ADC is functioning. The Power-down mode saves the

rupt or hardware reset. The Standby mode is the same as the Power-down mode, but external

oscillators are enabled. The wakeup or interrupt on pin change features enable the ATtiny26(L)

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

the Power-down mode.

The device is manufactured using Atmel’s high density non-volatile memory technology. By

combining an enhanced RISC 8-bit CPU with Flash on a monolithic chip, the ATtiny26(L) is a

powerful microcontroller that provides a highly flexible and cost effective solution to many

embedded control applications.

The ATtiny26(L) 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.
