Open IC ATtiny15 protected memory
Open IC ATtiny15 Protected Memory
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) which can be viewed after Open IC ATtiny15 protected memory, 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 voltage input with optional 20x gain, and three protected memory-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 hardware reset.
The wake-up or interrupt on pin change features enable the ATtiny15 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 ATtiny15 is a powerful 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 ATtiny15 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 after Open IC ATtiny15 protected memory.
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.
