TI LM3S6432

LM3S6432 Allgemeine Beschreibung

Texas Instruments' LM3S6432 is a part of the Stellaris LM3S6000 series, featuring a powerful 32-bit ARM Cortex-M3 processor running at speeds of up to 50 MHz. With 64 KB of flash memory and 8 KB of SRAM, it is well-equipped for a wide range of embedded applications, offering peripherals such as UART, SPI, I2C, and GPIO. The microcontroller's power management features, including sleep modes and multiple low-power modes, enable energy-efficient operation in battery-powered devices. Moreover, the LM3S6432 comes with a 10-bit ADC with up to 12 channels, allowing for precise analog signal measurements, and supports communication protocols like USB, Ethernet, and CAN, making it ideal for connectivity-driven applications. With support for industry-standard development tools such as Keil MDK or IAR Embedded Workbench, programming the LM3S6432 is straightforward and convenient
