Product details
Overview
MSP430F4250IRGZR from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 16 KB Flash, 256 B RAM, a 16-bit sigma-delta ADC with five differential analog inputs, a 12-bit DAC, Timer_A3 with three capture/compare registers, and integrated LCD driver supporting up to 56 segments. It operates from 1.8 V to 3.6 V and targets battery-powered metering and sensor interfaces.
For engineers reviewing the MSP430F4250IRGZR datasheet, MSP430F4250IRGZR pinout, MSP430F4250IRGZR application, or MSP430F4250IRGZR equivalent, key selection criteria include standby current (1.1 μA), wake-up time (<6 μs), LCD segment drive capability (56 seg), sigma-delta ADC resolution (16-bit), and QFN-48 package compatibility with space-constrained portable designs.
Technical Context
The MSP430F4250IRGZR integrates a 16-bit RISC CPU with constant generators and a digitally controlled oscillator (DCO) that achieves active-mode operation at up to 8 MHz (VCC = 3.6 V) and enables sub-6-μs wake-up from LPM4. Its FLL+ module locks DCO frequency to multiples of a 32.768-kHz watch crystal, providing stable ACLK, MCLK, and SMCLK domains.
Peripherals are memory-mapped and accessible via full instruction set support. The SD16_A ADC uses internal reference and supports programmable gain, offset calibration, and conversion rates up to 1 kSPS; the DAC12 provides voltage-output mode with 12-bit precision and software-selectable 8-/12-bit resolution.

FAQ
What is the maximum operating frequency of the MSP430F4250IRGZR at 3.6 V?
The MSP430F4250IRGZR supports a maximum system clock (MCLK) frequency of 8 MHz when supplied at 3.6 V. This is achieved using the FLL+ module locked to an external 32.768-kHz crystal or internal DCO. At lower voltages (e.g., 1.8 V), the maximum frequency is reduced to 4.15 MHz per the recommended operating conditions table in SLAS455D.
Does the MSP430F4250IRGZR support in-system programming without external hardware?
Yes, the MSP430F4250IRGZR includes a factory-programmed bootstrap loader (BSL) that enables in-system programming via UART using only P1.0 (TXD) and P1.1 (RXD). No external programmer or JTAG interface is required for field firmware updates, provided the BSL password has not been erased or overwritten.
How many LCD segments can the MSP430F4250IRGZR drive, and what multiplexing options are supported?
The MSP430F4250IRGZR's LCD_A module drives up to 56 segments using static, 2-MUX, 3-MUX, or 4-MUX configurations. It provides four common outputs (COM0–COM3) and 32 segment outputs (S0–S31), enabling flexible display layouts. Contrast is software-adjustable via internal charge pump voltage control registers.
What ADC resolution and input configuration does the MSP430F4250IRGZR provide?
The MSP430F4250IRGZR integrates a 16-bit sigma-delta SD16_A ADC with five differential analog input channels (A0+/- through A4+/-), internal reference, and programmable gain. It supports single-ended and differential conversions with built-in offset calibration and up to 1 kSPS sampling rate-optimized for precision DC and low-frequency AC measurements.
Is the MSP430F4250IRGZR pin-compatible with other members of the MSP430F42x0 family?
Yes, the MSP430F4250IRGZR is pin-compatible with the MSP430F4260IRGZR and MSP430F4270IRGZR in the RGZ (48-pin QFN) package. All share identical pin functions, electrical characteristics, and peripheral mappings-enabling hardware reuse across Flash size variants without PCB redesign.
