Product details
Overview
MSP430F2272IYFFT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 32KB+256B flash memory, 1KB 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 systems requiring precise analog capture and low-energy processing.
For engineers reviewing the MSP430F2272IYFFT datasheet, MSP430F2272IYFFT pinout, MSP430F2272IYFFT application, or MSP430F2272IYFFT equivalent, key selection criteria include its YFF (49-pin BGA) package, -40°C to +85°C industrial temperature grade, integrated brownout detector, sub-1-µs wake-up from LPM4, and Spy-Bi-Wire debug interface compatibility.
Technical Context
The MSP430F2272IYFFT 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 (calibrated to ±1% at 1 MHz, 8 MHz, 12 MHz, 16 MHz), 32-kHz crystal (ACLK), and external HF crystal/resonator up to 16 MHz.
It integrates two independent USCI modules: USCI_A0 for UART/LIN/IrDA/SPI and USCI_B0 for SPI/I²C, plus a 10-bit ADC10 with 12 input channels, sample-and-hold, data transfer controller (DTC), and selectable internal/external reference. The device lacks operational amplifiers - confirmed by family documentation restricting OA0/OA1 to MSP430F22x4 variants only.

FAQ
What is the maximum operating frequency of the MSP430F2272IYFFT?
The MSP430F2272IYFFT supports a maximum system clock (MCLK) frequency of 16 MHz, achievable using the internal digitally controlled oscillator (DCO) with factory calibration or an external HF crystal/resonator. This frequency is fully supported across the entire 1.8 V–3.6 V supply range and -40°C to +85°C temperature range, as verified in the SLAS504G datasheet timing specifications.
Does the MSP430F2272IYFFT include operational amplifiers?
No, the MSP430F2272IYFFT does not include operational amplifiers. Operational amplifiers OA0 and OA1 are exclusive to the MSP430F22x4 family members (e.g., MSP430F2274IYFFT). The MSP430F2272IYFFT datasheet explicitly lists "Two Configurable Operational Amplifiers (MSP430F22x4 Only)" in its feature summary, confirming their absence in this variant.
What debug interface does the MSP430F2272IYFFT support?
The MSP430F2272IYFFT supports the Spy-Bi-Wire (SBW) debug interface using two dedicated pins: TEST/SBWTCK (pin 1) and RST/NMI/SBWTDIO (pin 6). This 2-wire JTAG variant enables full programming, breakpoint setting, and real-time variable inspection through tools like MSP-FET430UIF, without requiring a 4-pin JTAG header.
How many ADC input channels does the MSP430F2272IYFFT have?
The MSP430F2272IYFFT features a 10-bit ADC10 module with 12 configurable analog input channels (A0–A7, A12–A15), as confirmed in Table 3 of the SLAS504G datasheet. Channel mapping includes P2.0/A0, P2.1/A1, P2.2/A2, P2.3/A3, P2.4/A4, P3.0/A5, P3.6/A6, P3.7/A7, P4.3/A12, P4.4/A13, P4.5/A14, and P4.6/A15.
What is the purpose of the P2.5/ROSC pin on the MSP430F2272IYFFT?
The P2.5/ROSC pin on the MSP430F2272IYFFT serves as the resistor input for the internal digitally controlled oscillator (DCO), allowing frequency tuning via an external resistor. When used with a crystal, it functions as the crystal oscillator input terminal. Its dual role enables flexible clock source selection - either RC-based low-cost timing or crystal-based high-precision operation - without requiring additional external components.
