Product details
Overview
MSP430F2252TDA 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, IrDA, SPI, and I²C - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2252TDA datasheet, MSP430F2252TDA pinout, MSP430F2252TDA application, or MSP430F2252TDA equivalent, key selection criteria include its -40°C to 105°C extended temperature rating, TSSOP-38 package compatibility, brownout detector, sub-1µs wake-up from LPM4, and integrated DCO with four factory-calibrated frequencies.
Technical Context
The MSP430F2252TDA implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock system supports internal DCO (up to 16 MHz, ±1% calibration), 32-kHz crystal, HF crystal, resonator, or external digital clock sources.
It integrates two independent USCI modules: USCI_A0 for UART/LIN/IrDA/SPI and USCI_B0 for SPI/I²C; a 10-bit ADC10 with 12-channel analog input multiplexing, sample-and-hold, and data transfer controller (DTC); and full Spy-Bi-Wire debug support via RST/NMI/SBWTDIO and TEST/SBWTCK pins.

FAQ
What is the maximum operating frequency of the MSP430F2252TDA?
The MSP430F2252TDA supports a maximum system clock (MCLK) of 16 MHz via its digitally controlled oscillator (DCO), which is factory-calibrated to ±1% accuracy across temperature and voltage. This allows deterministic real-time execution of time-critical tasks such as ADC sampling control and UART baud generation without requiring an external crystal.
Does the MSP430F2252TDA include hardware-based security features?
Yes, the MSP430F2252TDA includes programmable code protection via a security fuse that disables further flash access after programming. It also supports a password-protected bootstrap loader (BSL) with configurable lock bits - preventing unauthorized readout or reprogramming of firmware in deployed devices.
Can the MSP430F2252TDA operate without an external crystal?
Yes, the MSP430F2252TDA can operate entirely from its internal DCO, which provides four factory-trimmed frequencies (including 1 MHz, 4 MHz, 8 MHz, and 12 MHz) accurate to ±1%. This eliminates the need for external crystals in cost-sensitive or space-constrained designs while maintaining reliable timing for UART, ADC, and timer functions.
How many analog input channels does the ADC10 support on the MSP430F2252TDA?
The ADC10 module on the MSP430F2252TDA supports up to 12 analog input channels: A0–A7 (P2.0, P2.1, P2.2, P2.3, P2.4, P3.6, P3.7, P4.3–P4.6), plus internal temperature sensor and VREF outputs. Channel selection is fully software-configurable with autoscan mode enabling sequential conversion without CPU intervention.
Is the MSP430F2252TDA pin-compatible with other devices in the MSP430F22x2 family?
Yes, the MSP430F2252TDA shares identical pinout, electrical characteristics, and peripheral mapping with all TSSOP-38 variants in the MSP430F22x2 family (e.g., MSP430F2232TDA, MSP430F2272TDA), enabling direct substitution within the same package footprint and simplifying design reuse across memory-size variants.
