The 32-bit single-core Cortex-M3 delivers a deterministic interrupt response and a hardware divide unit — the sort of core that handles a sensor-fusion loop or a motor-control FOC cycle without jitter from a software scheduler. ## Peripheral set and analog integration The Cap Sense peripheral handles capacitive touch buttons or sliders directly — no dedicated touch controller needed. Connectivity includes I²C, SPI, USART, and USB — enough for a fieldbus gateway or a data-logger that talks to a host PC over USB. The IrDA and LINbus support targets automotive or industrial serial links where a standard UART won't reach. The LCD peripheral drives a segment LCD panel directly, which saves a display driver IC in metering or HMI applications. ## Supply voltage and temperature envelope STMicroelectronics lists this part as Active in production and ROHS3 compliant. A four-layer board is not strictly required, but a solid ground pour under the package helps with both thermal and EMI performance. With 37 I/O lines available, the LQFP-48 package gives enough pins for a sensor array, a small keypad, and a parallel LCD interface without multiplexing. The remaining pins are dedicated to power, ground, and the oscillator.","metaTitle":"STM32L152CCT6 STM32L1 ARM Cortex-M3 MCU, 32 MHz, 48-LQFP","metaDescription":"STMicroelectronics STM32L152CCT6 ARM Cortex-M3 MCU, 32 MHz, 256 KB Flash, 32 KB RAM, 8 KB EEPROM, 48-LQFP.

The key difference is the ADC channel count: the STM32L152CCT6 has 14x12-bit ADC channels, while the STM32L151CBU6A has 16x12-bit channels. The package also differs — the STM32L152CCT6 comes in a 48-LQFP, whereas the STM32L151CBU6A is in a UFQFPN-48 package. The pinout is not identical, so a board layout change is required to swap between them."},{"question":"What compliance documentation does STMicroelectronics provide for STM32L152CCT6?","answer":"The part is ROHS3 compliant.
