Product details
Overview
MSP430F2252IYFFT from Texas Instruments is an ultra-low-power 16-bit mixed-signal microcontroller featuring 16KB+256B flash, 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 - deployed in battery-powered sensor nodes and portable measurement systems.
For engineers reviewing the MSP430F2252IYFFT datasheet, MSP430F2252IYFFT pinout, MSP430F2252IYFFT application, or MSP430F2252IYFFT equivalent, key selection criteria include its YFF (49-pin BGA) package, -40°C to 85°C industrial temperature grade, 1.8–3.6 V supply range, sub-1 µs wake-up from LPM4, and integrated brownout detection for robust operation in energy-constrained embedded designs.
Technical Context
The MSP430F2252IYFFT 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 integrates a digitally controlled oscillator (DCO), calibrated internal frequencies up to 16 MHz (±1%), and support for 32-kHz crystal, HF crystal (≤16 MHz), resonator, or external digital clock sources.
It features two independent 16-bit timers - Timer_A3 with three capture/compare registers and Timer_B3 with three capture/compare registers plus shadow registers - alongside a universal serial communication interface (USCI) with dual channels: USCI_A0 (UART/LIN/IrDA/SPI) and USCI_B0 (SPI/I²C). Unlike the F22x4 series, this device lacks operational amplifiers.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F2272IYFFT | 32KB+256B flash, 1KB RAM - double flash capacity and 2× RAM vs. MSP430F2252IYFFT | Suitable for larger firmware images requiring bootloader, OTA updates, or extended data buffers | Select when firmware complexity exceeds 16KB or runtime data structures require >512B RAM |
| MSP430G2553IPW28R | 20-pin TSSOP, 16KB flash, 512B RAM, but no Timer_B - only Timer_A and USCI_A/B; lower pin count and cost | Targeted at simpler, space-constrained designs where dual 16-bit timers or 49-pin BGA density is unnecessary | Choose for cost-sensitive, low-I/O-count applications where Timer_B3 and YFF package are not required |
Compared with MSP430F2272IYFFT, the MSP430F2252IYFFT offers optimal balance of flash/RAM for mid-complexity sensor firmware while maintaining identical peripheral set and YFF packaging; versus MSP430G2553IPW28R, it delivers higher integration density, full Timer_B3 capability, and superior thermal performance in BGA form factor.

FAQ
What is the maximum operating frequency of the MSP430F2252IYFFT?
The MSP430F2252IYFFT supports a maximum system clock (MCLK) of 16 MHz, achieved via its internally calibrated digitally controlled oscillator (DCO) or external HF crystal. This frequency is fully supported across the entire -40°C to +85°C temperature range and 1.8–3.6 V supply, enabling deterministic real-time processing for time-critical sensor fusion tasks within the MSP430F2252IYFFT's power budget.
Does the MSP430F2252IYFFT include operational amplifiers?
No, the MSP430F2252IYFFT does not include operational amplifiers. Operational amplifiers are exclusive to the MSP430F22x4 series (e.g., MSP430F2254IYFFT), which integrates two configurable OAs. The MSP430F2252IYFFT belongs to the F22x2 series and omits OA circuitry, reducing die size and power consumption while retaining full ADC, timer, and communication functionality.
What debug interface does the MSP430F2252IYFFT support?
The MSP430F2252IYFFT supports Spy-Bi-Wire (SBW) debugging and programming via the TEST/SBWTCK and RST/NMI/SBWTDIO pins - a 2-wire variant of JTAG that requires only two PCB traces. This interface is fully compatible with TI's MSP-FET430UIF debugger and enables full flash programming, real-time breakpoints, and register inspection without requiring a 4-pin JTAG header, simplifying layout for the MSP430F2252IYFFT's 49-pin BGA package.
How many ADC input channels does the MSP430F2252IYFFT support?
The MSP430F2252IYFFT supports 12 analog input channels (A0–A7, A12–A15) for its 10-bit ADC10 module. Channels A0–A7 map directly to P2.0, P2.1, P2.2, P2.3, P2.4, P3.6, P3.7, and P2.5 respectively; A12–A15 are routed to P4.3, P4.4, P4.5, and P4.6. This configuration allows simultaneous connection of multiple analog sensors - such as thermistors, potentiometers, and current shunts - within the MSP430F2252IYFFT's compact BGA footprint.
Is the MSP430F2252IYFFT pin-compatible with other packages in the F22x2 family?
Yes, the MSP430F2252IYFFT shares identical functionality and pin mapping with the DA (38-pin TSSOP) and RHA (40-pin QFN) variants of the same device - MSP430F2252IDA and MSP430F2252IRHA. All three share the same signal names, electrical characteristics, and register-level behavior; only mechanical dimensions, thermal performance, and board assembly requirements differ. Migration between packages requires only PCB layout changes, not firmware modification for the MSP430F2252IYFFT.
