The 31 GPIOs and serial interfaces (I²C, IrDA, SCI, SPI, UART/USART) cover the common bus protocols for connecting an LCD, radio module, or external EEPROM. The device is rated over the -40 °C to 85 °C industrial temperature range and comes in a 38-pin TSSOP package (6.10 mm body width), suited for outdoor telecom cabinets, factory automation panels, and under-hood automotive auxiliary electronics where the environment stays below 85 °C ambient. ## 48 KB FRAM — what it means for field updates and data logging The 2 KB SRAM is sized for a small call stack and temporary buffers. Most real-time data handling should target FRAM directly for non-volatile storage — the 48 KB program space doubles as NVRAM once the code footprint is fixed.","metaTitle":"TI MSP430FR5858IDAR 16-bit MCU, 16 MHz, 48 KB FRAM, 38-TSSOP","metaDescription":"MSP430FR5858IDAR from Texas Instruments: 16-bit MSP430 CPUXV2, 16 MHz, 48 KB FRAM, 2 KB RAM, 31 GPIO, I²C/SPI/UART, -40 to 85 °C, 38-TSSOP.
