Product details
Overview
MSP430F2234TDA from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 8KB+256B flash, 512B RAM, dual operational amplifiers, 10-bit 200-ksps ADC with integrated reference and DTC, two 16-bit timers (Timer_A and Timer_B), USCI_A0/USCI_B0 interfaces (UART/LIN/IrDA/SPI/I²C), and 32 I/O pins - deployed in sensor signal acquisition, battery-powered metering, and RF front-end control systems.
For engineers reviewing the MSP430F2234TDA datasheet, MSP430F2234TDA pinout, MSP430F2234TDA application, or MSP430F2234TDA equivalent, key selection criteria include its −40°C to +105°C temperature grade, TSSOP-38 package, dual-op-amp analog front-end capability, ultra-low active-mode current (270 µA @ 1 MHz, 2.2 V), and integrated Spy-Bi-Wire debug interface.
Technical Context
The MSP430F2234TDA implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its clock system integrates a digitally controlled oscillator (DCO) with four factory-calibrated frequencies (±1%), internal VLO (12 kHz), and support for 32-kHz crystal, HF crystal up to 16 MHz, resonator, or external digital clock.
It features two independent operational amplifiers (OA0 and OA1) with configurable inputs/outputs across multiple pins (e.g., P2.0/OA0I0, P4.3/OA0O, P2.3/OA1I1/OA1O), enabling programmable gain stages and sensor signal conditioning. The ADC10 supports autoscan across 12 analog inputs (A0–A7, A12–A15), internal reference (1.5 V/2.0 V/2.5 V), and data transfer controller (DTC) for autonomous conversion-to-memory transfers without CPU intervention.
