The industrial grade means the oscillator, ADC, and Flash retention are characterised across the full range — no surprises when the enclosure heats up in July or the panel powers up at -30°C. ## Built-in analog: ADC and DAC Yes, the STM32L452RET6P includes a 12-bit ADC with 16 channels and a single 12-bit DAC. That DAC is handy for generating analog setpoints, audio waveforms, or control voltages without an external converter. The ADC covers enough channels to read multiple sensor inputs — thermistors, potentiometers, current shunts — through one chip. ## Connectivity that covers the common buses The peripheral set includes CANbus, I²C, SPI, UART/USART, USB, QSPI, SAI, and MMC/SD — essentially everything you need for industrial control, data logging, or human-machine interface without adding external interface chips. QSPI is particularly useful for connecting external Flash or PSRAM for data logging or graphics buffers.","metaTitle":"STM32L452RET6P STM32L4 MCU, 80MHz, 512KB Flash, 64-LQFP","metaDescription":"STM32L452RET6P is a 32-bit ARM Cortex-M4 MCU from ST's STM32L4 series, 80MHz, 512KB Flash, 160KB SRAM, 64-LQFP, -40°C to 85°C.

Both share the same 64-LQFP package, 80 MHz ARM Cortex-M4 core, 160 KB SRAM, and peripheral set. The RET6P is the higher-density option for firmware that needs more code space."},{"question":"Does STM32L452RET6P have a built-in DAC?","answer":"Yes, it includes one 12-bit DAC channel alongside a 16-channel 12-bit ADC. The DAC can be used for analog output without an external converter."},{"question":"What is the maximum clock frequency of STM32L452RET6P?","answer":"The maximum core clock is 80 MHz. That is the speed rating for the ARM Cortex-M4 core with FPU, which gives you enough throughput for real-time control loops, sensor processing, and communication protocol stacks."},{"question":"Is STM32L452RET6P compatible with STM32L452RE?","answer":"The base part number STM32L452RE covers the same silicon.
