STSPIN32F0TR ST Motor Control Arm Cortex-M0 MCU with Integrated Triple Half-Bridge Gate Driver 32KB Flash 4KB SRAM VFQFPN-48

STSPIN32F0TR Product Overview

STSPIN32F0TR is an Arm Cortex-M0 (48 MHz) motor-control SoC from STMicroelectronics in a VFQFPN-48 package. The STSPIN32F0TR integrates 32 KB Flash, 4 KB SRAM, a triple half-bridge gate driver (1 A source/sink), bootstrap diodes, a 12-bit ADC (10 ch, 1 Msps), four comparators, three rail-to-rail op-amps for current sensing, I2C/UART/SPI interfaces, an advanced PWM timer, and comprehensive protection features (OCP, OTP, UVLO, deadtime insertion). The STSPIN32F0TR operates from a supply range of 8 V–45 V with an integrated 3.3 V LDO, offering up to 15 general-purpose I/Os and an operating temperature of -40–125 °C. By merging Cortex-M0 real-time control, a motor-drive analog front-end, and power management into a single chip, the STSPIN32F0TR enables complete single- or three-shunt FOC and trapezoidal motor drives with minimal external components.
