Product details
Overview
MSP430F2252IYFFR 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 a Universal Serial Communication Interface supporting UART/LIN, IrDA, SPI, and I²C. It operates from 1.8 V to 3.6 V and targets battery-powered sensor acquisition and embedded control systems.
For engineers reviewing the MSP430F2252IYFFR datasheet, MSP430F2252IYFFR pinout, MSP430F2252IYFFR application, or MSP430F2252IYFFR equivalent, key selection criteria include its 49-pin BGA (YFF) package, integrated brownout detector, sub-1-µs wake-up from standby mode, and support for Spy-Bi-Wire debugging - all critical for space-constrained, energy-sensitive designs.
Technical Context
The MSP430F2252IYFFR implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations. Its basic clock system includes a digitally controlled oscillator (DCO) calibrated to ±1% at 1 MHz, plus support for 32-kHz crystal, HF crystal up to 16 MHz, resonator, or external digital clock source.
It integrates two independent 16-bit timers with capture/compare registers, a USCI module with dual channels (USCI_A0 for UART/LIN/IrDA/SPI and USCI_B0 for SPI/I²C), and a 10-bit ADC10 with 12 analog input channels, sample-and-hold, and data transfer controller (DTC). Unlike the MSP430F22x4 series, this device does not include operational amplifiers.

FAQ
What is the maximum operating frequency of the MSP430F2252IYFFR?
The MSP430F2252IYFFR supports a maximum system clock (MCLK) frequency of 16 MHz when using an external HF crystal or resonator. Its internal DCO is factory-calibrated to ±1% accuracy at 1 MHz, and can be adjusted across a wide range, but sustained 16-MHz operation requires external timing source per the SLAS504G datasheet specifications.
Does the MSP430F2252IYFFR include operational amplifiers?
No, the MSP430F2252IYFFR does not include operational amplifiers. Operational amplifiers are exclusive to the MSP430F22x4 series (e.g., MSP430F2254IYFFR). The MSP430F2252IYFFR is part of the F22x2 series and omits OA0 and OA1 blocks, as confirmed in the device family functional block diagrams and terminal function tables.
What debug interface does the MSP430F2252IYFFR support?
The MSP430F2252IYFFR supports Spy-Bi-Wire (SBW) debugging via the TEST/SBWTCK and RST/NMI/SBWTDIO pins. This 2-wire interface provides full JTAG-equivalent functionality including flash programming, breakpoints, and real-time register inspection - eliminating the need for a 4-wire JTAG header in space-constrained layouts.
Is the MSP430F2252IYFFR pin-compatible with other packages in the F22x2 family?
Yes, the MSP430F2252IYFFR shares identical pin functions and signal mapping with the MSP430F2252IDA (38-pin TSSOP) and MSP430F2252IRHA (40-pin QFN), as defined in Table 1 and Terminal Function Tables 3–4 of SLAS504G. However, mechanical layout, thermal pad configuration, and routing constraints differ significantly between YFF, DA, and RHA packages.
What ADC features are supported by the MSP430F2252IYFFR?
The MSP430F2252IYFFR integrates the ADC10 module with 10-bit resolution, 200-ksps sampling rate, 12 selectable analog input channels (A0–A7, A12–A15), internal reference (1.5 V or 2.5 V), sample-and-hold, autoscan mode, and data transfer controller (DTC) - enabling fully autonomous conversion sequences without CPU overhead.
