Active production 16-bit MCU for industrial control
The MSP430F249TRGCT is an active-production 16-bit MCU from Texas Instruments' MSP430F2xx family, built around the MSP430 CPU16 core running at 16 MHz. The 48 general-purpose I/O lines, combined with I²C, SPI, UART, IrDA, LINbus, and SCI serial interfaces, cover the common communication buses found in mixed-signal control boards. An 8-channel 12-bit ADC brings analog sensor inputs directly into the digital domain without an external converter.
On-chip peripherals reduce BOM count
Built-in brown-out detect and power-on reset eliminate the need for an external supervisor IC. The internal oscillator frees up a crystal footprint, and the PWM timer handles simple motor or LED dimming without a dedicated PWM controller. The watchdog timer provides a fail-safe reset if the firmware hangs.
