1 Overview
1 Overview
T1-U has a built-in 32-bit MCU with a maximum running speed of 160 MHz, built-
in 1 MB flash memory, and 288 KB RAM. The module supports cloud connectivity,
and the MCU ’s extended instructions for signal processing enable it to efficiently
implement audio encoding and decoding. Various peripherals are available, such as
PWM, UART, and SPI. Up to five channels of 32-bit PWM output make the chip ideal
for high-quality LED control.
1.1 Features
