The 25 MHz clock rate and 32 KB RAM support a Modbus RTU stack and a PID loop simultaneously. ## Temperature grade and deployment environment ## Peripherals and on-chip resources The 12-channel 10-bit ADC covers basic analog sensing — enough for temperature, current, or voltage monitoring on a control board, but not for high-resolution data acquisition where a 12-bit or 16-bit external ADC would be specified. For IrDA or high-speed UART, a crystal may still be advisable. TI lists the MSP430F5259IRGCT as Active. We source this part through independent distribution and quote it to order against an RFQ.","metaTitle":"TI MSP430F5259IRGCT 16-bit MCU, 25 MHz, 128 KB Flash, 32 KB RAM","metaDescription":"Texas Instruments MSP430F5259IRGCT 16-bit MSP430 CPUXV2 MCU, 25 MHz, 128 KB Flash, 32 KB RAM, 53 I/O, I²C/SPI/UART, -40°C to 85°C, 64-VQFN.
