STMicroelectronics STM32L

Beschreibung

The STM32L-DISCOVERY (order code STM32L-DISCOVERY) and the32L152CDISCOVERY (order code STM32L152C-DISCO) help you to discover the STM32L ultra low power features and to develop and share your applications. The STM32LDISCOVERY and 32L152CDISCOVERY are based on an STM32L152RBT6 (128 Kbytes of Flash memory) and an STM32L152RCT6 (256 Kbytes of Flash memory), respectively.

They include an ST-LINK/V2 embedded debug tool interface, LCD (24 segments, 4 commons), LEDs, pushbuttons, a linear touch sensor, and four touchkeys. In this document, STM32L1 discovery refers both to the STM32L-DISCOVERY and to the 32L152CDISCOVERY. STM32L-DISCOVERY and 32L152CDISCOVERY kits are functionally equivalent. The difference is the internal Flash memory size (128 Kbytes or 256 Kbytes).

Eigenschaften

• An STM32L152RBT6 (128 Kbyte Flash memory, 16 Kbyte RAM, 4 Kbyte data EEPROM) or STM32L152RCT6 (256 Kbyte Flash memory, 32 Kbyte RAM, 8 Kbyte data EEPROM) microcontroller in a 64-pin LQFP package
• On-board ST-LINK/V2 with selection mode switch to use the kit as a standalone STLINK/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
• IDD current measurement
• LCD
• – DIP28 package
• – 24 segments, 4 commons
• Four LEDs:
• – LD1 (red/green) indicating USB communication
• – LD2 (red) indicating that 3.3 V power supply is ON
• – Two user LEDs, LD3 (green) and LD4 (blue)
• Two pushbuttons (user and reset)
• One linear touch sensor and four touchkeys
• Extension header for LQFP64 I/Os for quick connection to prototyping board and easyprobing
