STM8AL3L66TCY ST Microcontroller | 32-LQFP (7x7) | 8-bit, 32KB Flash, 2KB RAM

Product Overview

The STM8AL3L66TCY is an 8-bit microcontroller from STMicroelectronics' STM8AL series, designed for ultra-low-power applications. It features a high-performance STM8 core operating at up to 16 MHz, 32 KB of Flash memory, 2 KB of RAM, and 1 KB of EEPROM. The device is housed in a compact 32-LQFP (7x7 mm) package, making it suitable for space-constrained designs. It offers a rich set of peripherals including multiple timers, communication interfaces (SPI, I2C, UART), and analog features such as a 12-bit ADC and comparators. The STM8AL3L66TCY is optimized for battery-powered and energy-efficient systems, with multiple low-power modes including Active-Halt and Wait.
