Product details
Overview
MSP430F2252TDAR from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16KB+256B flash, 512B RAM, 10-bit 200-ksps ADC with internal reference and autoscan, dual 16-bit timers (Timer_A3 and Timer_B3), and USCI modules supporting UART/LIN, SPI, and I²C - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2252TDAR datasheet, MSP430F2252TDAR pinout, MSP430F2252TDAR application, or MSP430F2252TDAR equivalent, key selection criteria include its -40°C to 105°C industrial temperature grade, TSSOP-38 package, 1.8–3.6 V supply range, sub-1 µs wake-up from LPM4, and integrated brownout detector for robust operation in energy-constrained embedded designs.
Technical Context
The MSP430F2252TDAR implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock system includes DCO (calibrated to ±1% at 1 MHz), ACLK from 32-kHz crystal or internal VLO, and SMCLK derived from DCO or external source.
It integrates two independent USCI modules: USCI_A0 supports enhanced UART with auto-baud detection (LIN-compliant), IrDA encoding/decoding, and synchronous SPI; USCI_B0 supports SPI and I²C master/slave modes. The ADC10 features 12 analog input channels, sample-and-hold, data transfer controller (DTC), and selectable internal/external reference.
