[GD] STM32L Discovery

STM32 저전력 MCU 입니다.

LCD 인터페이스에 Analog Comparator, OPAMP까지 들어 있고,

EEPROM도 들어 있네요.

CORTEX-M3 Platform 그대로 활용 할 수 있어서 저전력 기기 구성시 사용하면 좋을 듯 합니다.

32L152CDISCOVERY

Discovery kit for STM32L151/152 line - with STM32L152RC MCU

• Active

The STM32L-DISCOVERY and 32L152CDISCOVERY kits help you to discover the STM32L ultra low power features and to develop and share your applications.

They are based on an STM32L152RBT6 and an STM32L152RCT6, respectively; and include an ST-Link/V2 embedded debugging tool interface, an LCD (24 segments, 4 commons), LEDs, pushbuttons, a linear touch sensor or touchkeys.

• On-board ST-Link/V2 with selection mode switch to use the kit as a standalone ST-Link/V2 (with SWD connector for programming and debugging)
• Board power supply: through USB bus or from an external 3.3 or 5 V supply voltage
• External application power supply: 3 V and 5 V
• I_DD current measurement
• LCD
• DIP28 package
• 24 segments, 4 commons
• Four LEDs:
• LD1 (red/green) for USB communication
• LD2 (red) for 3.3 V power on
• Two user LEDs, LD3 (green) and LD4 (blue)
• Two pushbuttons (user and reset)
