HT32F52241

HT32F52241 is an Arm Cortex-M0+ microcontroller from Holtek running at 40 MHz with 64 KB of Flash and 8 KB of SRAM, a 2.0 V to 3.6 V supply and a 12-bit 1 Msps ADC with 12 channels. USART, dual UART, dual SPI and dual I2C interfaces plus motor and general-purpose timers target white goods, power monitors, alarm systems and consumer controls, and the official HT32 selection guide lists the part as a current production model with the data sheet still revised in 2024. Selection advice: Holtek publishes no package-suffixed order codes for this MCU - the base name plus package is the manufacturer's own ordering form (its Best Modules store sells it as HT32F52241 48LQFP), so state the package explicitly in your RFQ; 24-SSOP, 28-SSOP and 33-QFN options exist alongside this 48-LQFP version. The operating range is -40 to +85 C. Parameters verified against the Holtek HT32F52241 data sheet Rev. 2.10 and the official CMSIS device pack data.
