16-bit MSP430 core at 8 MHz — throughput ceiling and memory budget
The MSP430F149IPAGR is a 16-bit MCU built around the MSP430 CPU16 core running at 8 MHz — the clock ceiling that sets the instruction throughput for the control loop. On-chip memory breaks down as 60 KB of Flash for program storage and 2 KB of SRAM for data, which defines the firmware footprint and the runtime variable space available before external memory is needed. The 48 GPIOs, combined with SPI and UART/USART connectivity, let it interface with sensors, displays, and serial peripherals without external port expanders.
Mixed-signal peripherals and temperature grade
An 8-channel 12-bit ADC is integrated on-chip, so analog sensor inputs — temperature, pressure, current sense — are sampled directly without an external converter. The POR, PWM, and WDT peripherals handle power-on sequencing, waveform generation, and watchdog supervision in the same silicon.
64-TQFP package and board integration
Surface-mount assembly is standard; no through-hole staking or press-fit tooling is needed. The tape-and-reel packaging option (Cut Tape also available) suits automated pick-and-place lines for medium to high volumes. The base product number MSP430F149 is the design anchor for PCB footprints across the family.
Active production and compliance standing
As an active-series part (MSP430x1xx), it is sourced through authorized distribution channels. Volume pricing and lead time are confirmed at RFQ against the BOM quantity.
