16 MHz 8-bit MCU with integrated LCD and analog peripherals
The STMicroelectronics STM8L152C4T6 is an 8-bit microcontroller from the STM8L EnergyLite series, built around the STM8 core and clocked at 16 MHz. It packs 16 KB of Flash program memory, 2K x 8 of RAM, and 1K x 8 of EEPROM in a 48-pin LQFP package. On-chip peripherals include a 12-bit ADC with 25 channels, a single 12-bit DAC, an LCD driver, and multiple serial interfaces (I²C, IrDA, SPI, UART/USART). It is commonly used in battery-powered instrumentation, sensor nodes, and human-machine interface panels where low power and integrated LCD drive are needed.
Flash and EEPROM sizing for firmware and calibration data
The 16 KB Flash (16K x 8) is sized for moderate firmware loads — think bootloader plus application code for a sensor hub or a simple display controller. The separate 1K x 8 EEPROM block is useful for storing calibration constants, configuration parameters, or fault logs without wearing the Flash. The 2K x 8 RAM is tight for data buffers; designs that need larger packet handling or display frame buffers should budget carefully.
