Product Description
Microchip ATTINY824-XU is an 8 bit AVR CPU microcontroller from the tinyAVR® 2 family featuring a hardware multiplier and running at up to 20 MHz clock speed. It offers 8 KB of FLASH program memory, 1 KB of SRAM, and 256 bytes of EEPROM within a compact 14-pin TSSOP package designed for space-constrained applications.
This microcontroller supports flexible power management with a wide supply voltage range from 1.8 V to 5.5 V and operational temperature range of -40°C to 125°C, making it suitable for industrial and automotive environments compliant with AEC-Q100 standards.
The device includes advanced analog features such as a 12-bit differential ADC with a Programmable Gain Amplifier (PGA) and one analog comparator. Four timers provide precise timing functions, and 22 programmable I/O pins enable diverse peripheral interfaces.
The architecture includes single-cycle I/O access and a two-cycle hardware multiplier to enhance processing efficiency, complemented by a two-level interrupt controller with vectored interrupts. Additional features include Brown-out Detection (BOD), Power-on Reset (POR), and a watchdog timer with window mode.
This microcontroller supports a Single-pin Unified Program and Debug Interface (UPDI) for streamlined programming and debugging. It also incorporates multiple sleep modes to minimize power consumption, including idle, standby, and power-down with full data retention.
Operates with reliable flash endurance of 10,000 write/erase cycles and EEPROM endurance of 100,000 cycles. Guaranteed data retention up to 40 years at 55°C ensures long-term non-volatile memory stability. Includes a 32.768 kHz ultra-low power internal oscillator and supports external crystal oscillators for precise timing.
This microcontroller is ideal for embedded control systems used in automotive, industrial automation, instrumentation, and consumer electronics where high performance, low power, and compact packaging are required.
