STM32L4R9ZIY6PTR 32‑bit Microcontroller STM32L4 MCU
The STM32L4R9ZIY6PTR is an ultra-low-power microcontroller from STMicroelectronics' STM32L4+ series, featuring a high-performance Arm Cortex-M4 core with a single-precision floating-point unit (FPU) operating at up to 120 MHz . This 32-bit RISC MCU is housed in a compact 144-ball Wafer-Level Chip-Scale Package (WLCSP) measuring 5.3x5.3x0.6 mm with a 0.4 mm pitch, designed for industrial-grade applications with an operating temperature range of -40°C to +85°C . It is engineered to deliver an optimal balance of processing performance and energy efficiency, making it a cornerstone for advanced battery-powered and energy-conscious embedded systems .
Key features of the STM32L4R9ZIY6PTR center around its exceptional power management and rich peripheral integration . It incorporates ST's FlexPowerControl technology, supporting a wide supply voltage from 1.71V to 3.6V and achieving remarkably low power consumption: 305 nA in VBAT mode, 33 nA in Shutdown, 125 nA in Standby, and as low as 43 µA/MHz in Run mode when using an external SMPS . The device is equipped with an Adaptive Real-Time (ART) accelerator enabling zero-wait-state execution from its 2 MB of dual-bank Flash memory, alongside 640 KB of SRAM . It boasts advanced graphics capabilities with a Chrom-ART Accelerator (DMA2D), a Chrom-GRC for graphics resource optimization, a dedicated LCD-TFT controller, and a MIPI DSI host controller with two lanes running at up to 500 Mbps each .
