STM32L152D-EVAL

evaluation board

Introduction
The STM32L152D-EVAL evaluation board is a complete demonstration and development
platform for STMicroelectronic's ARM cortex-M3 core-based STM32L152ZDT6
microcontroller featuring two I2C, three SPI, five USART, 12-bit ADC, 12-bit DAC, LCD
driver, internal 48 KB SRAM and 384 KB Flash, touch sensing, USB FS, LCD controller,
FSMC and JTAG debugging support.
This board can be used as reference design for user application development but it is not
considered as final application. The full range of hardware features on the board helps you
evaluate all peripherals (USB FS, USART, audio DAC, microphone ADC, dot-matrix LCD,
LCD glass, IrDA, LDR, SRAM, NOR Flash, MicroSD Card, temperature sensor and so on)
and develop your own applications. Extension headers make it possible to easily connect a
daughterboard or wrapping board for your specific application.
An ST-LINK/V2 is integrated on the board as embedded in-circuit debugger and
programmer for the STM32 MCU.
