ATTINY28V-1AC Description

Short technical summary and product information.

The ATTINY28V-1AC is an 8-bit microcontroller from Microchip Technology based on the AVR core. It includes 2KB of Flash program memory (1K x 16) and operates from a supply voltage of 1.8V to 5.5V. The device has 11 programmable I/O lines, a single 8-bit timer/counter with prescaler, an analog comparator, a high-current LED driver, and an internal calibrated RC oscillator. These features reduce the need for external components and simplify board design.

The microcontroller supports a maximum clock speed of 1.2MHz and is designed for low-power operation. Typical supply current is 3.0mA in active mode and 1.2mA in idle mode at 1MHz and 2V, while power-down mode consumes less than 1µA. Built-in peripherals include power-on reset (POR), a programmable watchdog timer (WDT), and interrupt support for low-level inputs. The device operates over a temperature range of 0°C to 70°C (TA).

The ATTINY28V-1AC is offered in a 32-lead TQFP package (32-TQFP, 7x7mm) for surface-mount assembly. It is suitable for consumer electronics, industrial control, IoT devices, and smart sensors where small size and low power draw are important. Development is supported by Microchip Studio IDE and in-system programming (ISP).
