The ATTINY43U-MU is a high-performance, low-power 8-bit AVR microcontroller from Microchip Technology. It features 4KB of in-system programmable Flash memory, 256B of SRAM, and 64B of EEPROM, with endurance of 10,000 write/erase cycles for Flash and 100,000 for EEPROM. Data retention is rated at 20 years at 85°C and 100 years at 25°C.
The device integrates a boost converter enabling operation from a supply voltage as low as 0.7V, making it suitable for battery-powered applications. It operates at up to 8 MHz with a 2.7V to 5.5V supply, or up to 4 MHz in boost mode. Peripherals include a 10-bit ADC with 4 channels, two 8-bit timers with PWM, a watchdog timer, an analog comparator, a temperature sensor, and a Universal Serial Interface (USI).
The ATTINY43U-MU is offered in a 20-pin QFN package with an exposed pad for improved thermal performance. It supports debugWIRE on-chip debugging and in-system programming via SPI. Typical active mode current is 400 µA at 1 MHz and 3V, while power-down mode current is only 150 nA.
The ATTINY43U-MU operates from 0.7V to 1.8V with the boost converter enabled, or from 1.8V to 5.5V with the boost converter bypassed.
The ATTINY43U-MU is supplied in a 20-WFQFN Exposed Pad package, also designated as 20-QFN-EP (4x4 mm).
The ATTINY43U-MU is rated for an operating temperature range of -40°C to +85°C.
The ATTINY43U-MU is listed as RoHS3 compliant, though this status is unverified.
The ATTINY43U-MU has 4KB of in-system programmable Flash memory.
The maximum clock speed is 8 MHz at 2.7V to 5.5V, and 4 MHz at 0.7V to 1.8V (boost enabled) or 1.8V to 5.5V (boost bypassed).
Active mode current is 400 µA at 1 MHz, 3V (without boost converter). Power-down mode current is 150 nA at 3V (without boost converter).
