Product details
Overview
MSP430F2254IDA from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16KB+256B flash, 512B RAM, dual operational amplifiers, 10-bit 200-ksps ADC with internal reference and DTC, two 16-bit timers (Timer_A3 and Timer_B3), USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C), and 32 I/O pins - deployed in sensor signal acquisition, battery-powered measurement, and RF front-end control.
For engineers reviewing the MSP430F2254IDA datasheet, MSP430F2254IDA pinout, MSP430F2254IDA application, or MSP430F2254IDA equivalent, key selection criteria include its DA-package TSSOP-38 footprint, dual-op-amp analog front-end capability, LPM4 standby current of 0.1 µA, 16-MHz DCO clock with ±1% calibration, and integrated brownout detection for robust operation in energy-constrained embedded systems.
Technical Context
The MSP430F2254IDA implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its architecture supports five software-selectable low-power modes (LPM0–LPM4), with wake-up from LPM4 in under 1 µs via the digitally controlled oscillator (DCO).
It integrates two independent operational amplifiers (OA0 and OA1) with configurable inputs/outputs across P2.x, P3.x, and P4.x pins, supporting rail-to-rail input and output swing. The 10-bit ADC10 includes 12 analog input channels (A0–A7, A12–A15), sample-and-hold, autoscan, and data transfer controller (DTC) for autonomous conversions without CPU intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 16 registers and 62.5-ns instruction cycle time - enables deterministic real-time control and efficient C compilation. |
| Flash / RAM | 16KB + 256B flash memory and 512B RAM - sufficient for moderate firmware complexity with nonvolatile parameter storage. |
| ADC Resolution | 10-bit, 200-ksps SAR ADC with internal reference and DTC - supports high-throughput sensor sampling with DMA-like data movement. |
| Power Consumption | Active mode: 270 µA at 1 MHz/2.2 V; Standby: 0.7 µA; Off mode (RAM retention): 0.1 µA - extends battery life in portable instrumentation. |
| Operating Voltage | 1.8 V to 3.6 V supply range - compatible with single-cell Li-ion, Li-poly, or dual-AA alkaline power sources. |
| Clock System | Digital Controlled Oscillator (DCO) calibrated to ±1% at 1, 4, 8, and 12 MHz; supports 32-kHz crystal and HF crystal up to 16 MHz - eliminates external clock components in many designs. |

Pinout & Package
Package: 38-pin Thin Shrink Small-Outline Package (TSSOP-DA), 9.7 mm × 4.4 mm body, 0.65 mm pitch, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| P1.0/TACLK/ADC10CLK | Timer_A clock input / ADC conversion clock | Enables synchronous timer-triggered ADC sampling; supports external clock injection for precise timing control. |
| P2.0/ACLK/A0/OA0I0 | ACLK output / ADC channel A0 / OA0 inverting input | Shared pin allows direct connection of sensor signal to op-amp input while providing low-jitter clock for RTC or timer subsystems. |

| P3.6/A6/OA0I2 | ADC channel A6 / OA0 non-inverting input | Allows dedicated analog sensor interface to OA0 with simultaneous digitization via ADC - no multiplexer switching latency. |
| P4.4/TB1/A13/OA1O | Timer_B channel 1 / ADC A13 / OA1 output | OA1 output shared with ADC input enables closed-loop control where op-amp output directly feeds back into ADC for real-time error measurement. |
| RST/NMI/SBWTDIO | Reset / NMI input / Spy-Bi-Wire data I/O | Single-pin debug interface reduces PCB footprint; supports in-system programming and real-time emulation without JTAG header. |
