Microchip ATTINY84A-PU 8-Bit Microcontroller 20MHz DIP-14

Microchip ATTINY84A-PU 8-Bit Microcontroller is a high-performance, low-power 8-bit AVR RISC-based microcontroller from the ATtiny family, supplied in a 14-pin DIP package with 8KB of program memory.

Overview

This device combines 8KB of program memory, 512 bytes of EEPROM and 512 bytes of RAM in a compact 14-pin DIP package. Its advanced RISC architecture executes instructions in a single clock cycle, achieving throughputs approaching 1 MIPS per MHz, which allows power consumption and processing speed to be balanced. The microcontroller can run at speeds up to 20MHz across a supply voltage range of 1.8V to 5.5V.

Key Features

• 12 general-purpose I/O lines and 32 working registers
• Two timers/counters (8-bit and 16-bit), each with two PWM channels
• 8-channel 10-bit A/D converter with a programmable gain stage (1x, 20x)
• 12 differential ADC channel pairs, suited to analogue sensor applications
• Programmable watchdog timer with internal oscillator
• Internal calibrated oscillator and on-chip temperature sensor
• Enhanced power-on reset circuit and programmable brown-out detection with software disable function
• Four software-selectable power-saving modes: Idle, ADC Noise Reduction, Standby and Power-down

Power and Operation

Typical active mode current is 210µA at 1.8V and 1MHz, and idle mode current is 33µA. The operating temperature range is -40°C to +85°C.

Development and Programming

In-system programming is available via the SPI port, and the debugWIRE on-chip debug system supports development and field updates.
