STM32L486JGY6TR

The STM32L486JGY6TR is a high-performance 32-bit microcontroller from STMicroelectronics, built around the ARM Cortex-M4 core clocked at 80 MHz. This clock rate, combined with its single-cycle multiply-accumulate and floating-point unit, makes it suitable for real-time signal processing tasks such as sensor fusion, motor current loops, and audio front-ends.

With 1MB of on-chip Flash memory and 128KB of SRAM, this MCU provides ample space for complex applications, including full protocol stacks like USB and CAN, without requiring external memory. It offers 57 I/O lines, facilitating connections for parallel display buses or sensor arrays.

The peripheral set includes CANbus, USB OTG, QSPI, SAI, SWPMI, I²C, SPI, UART/USART, and IrDA, allowing a single chip to manage fieldbus gateways, human-machine interfaces, and audio codecs. Analog front-end tasks are supported by a 16-channel 12-bit ADC and dual 12-bit DAC. On-chip peripherals also include a DMA controller, PWM timer, brown-out detect/reset, and an LCD driver.

Packaged in a compact 72-WLCSP (4.41 x 3.76 mm), the STM32L486JGY6TR is designed for space-constrained applications like wearables and sensor nodes. It operates within an industrial temperature range of -40°C to 85°C and a supply voltage of 1.71V to 3.6V.
