Product details
Overview
MSP430F2252IDA from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16KB+256B flash memory, 512B RAM, a 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. It operates from 1.8 V to 3.6 V and targets battery-powered sensor acquisition and processing in portable measurement systems.
For engineers reviewing the MSP430F2252IDA datasheet, MSP430F2252IDA pinout, MSP430F2252IDA application, or MSP430F2252IDA equivalent, key selection considerations include its 38-pin TSSOP (DA) package, 32 I/O pins with analog input capability on 16 channels, brownout detection, and Spy-Bi-Wire debug interface - all optimized for low-power embedded sensing and control.
Technical Context
The MSP430F2252IDA implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its basic clock system includes a digitally controlled oscillator (DCO) calibrated to ±1% across four frequencies up to 16 MHz, plus support for 32-kHz crystal and HF crystal up to 16 MHz.
It integrates two independent universal serial communication interfaces: USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), alongside a 10-bit ADC10 with data transfer controller (DTC), 16-channel analog input multiplexing, and internal voltage reference. Unlike the MSP430F22x4 series, this device does not include operational amplifiers.

FAQ
What is the maximum operating frequency of the MSP430F2252IDA?
The MSP430F2252IDA supports a maximum system clock (MCLK) frequency of 16 MHz, achievable using the internal digitally controlled oscillator (DCO) calibrated to ±1% or an external HF crystal. This allows execution of instructions at 62.5-ns cycle time, enabling real-time signal processing in battery-constrained applications while maintaining ultra-low power consumption.
Does the MSP430F2252IDA include operational amplifiers?
No, the MSP430F2252IDA does not include operational amplifiers. It belongs to the MSP430F22x2 series, which omits the two configurable op-amps present in the MSP430F22x4 variants (e.g., MSP430F2254IDA). All documented features and pin functions for MSP430F2252IDA confirm absence of OA0/OA1 circuitry and related terminal assignments.
Which development tools are compatible with the MSP430F2252IDA?
The MSP430F2252IDA is supported by TI's MSP-FET430U38 debugger/programmer, designed specifically for DA-package devices, and the MSP-FET430UIF USB interface. It also works with Code Composer Studio and IAR Embedded Workbench. The integrated Spy-Bi-Wire interface eliminates need for full 4-wire JTAG headers, simplifying PCB layout and reducing debug footprint.
How many analog input channels does the MSP430F2252IDA ADC support?
The MSP430F2252IDA's ADC10 module supports up to 16 analog input channels (A0–A15), selectable via the ADC10CTL1 register. Channels A0–A7 map directly to P2.0–P2.3 and P3.6–P3.7; A8–A15 are routed through P4.3–P4.7. This full 16-channel capability enables simultaneous monitoring of multiple sensors without external multiplexers.
What low-power modes are available on the MSP430F2252IDA?
The MSP430F2252IDA provides six operating modes: Active Mode (AM) and five software-selectable low-power modes (LPM0–LPM4). LPM4 achieves 0.1 µA current draw with RAM retention and is exited in <1 µs via interrupt. Each mode selectively disables clocks (MCLK, SMCLK, ACLK) and subsystems (DCO, crystal oscillator) to match application idle requirements.
