Product details
Overview
MSP430FG4260IRGZT from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 24KB+256B Flash, 256B RAM, a 16-bit sigma-delta ADC with internal reference and five differential analog inputs, a 12-bit DAC, two configurable op-amps, Timer_A3 with three capture/compare registers, and integrated LCD driver supporting up to 56 segments - deployed in portable sensor systems and battery-powered metering.
For engineers reviewing the MSP430FG4260IRGZT datasheet, MSP430FG4260IRGZT pinout, MSP430FG4260IRGZT application, or MSP430FG4260IRGZT equivalent, key selection criteria include active-mode current (250 μA @ 1 MHz, 2.2 V), wake-up latency (<6 μs from standby), LCD segment drive capability (56 seg), sigma-delta ADC resolution (16-bit), and QFN-48 package compatibility with space-constrained embedded designs.
Technical Context
The MSP430FG4260IRGZT implements a 16-bit RISC CPU with constant generators and seven addressing modes, enabling single-cycle register operations and high code efficiency. Its FLL+ clock system integrates a digitally controlled oscillator (DCO) and supports ACLK (32.768 kHz crystal), MCLK (system clock), and SMCLK (peripheral clock), with fast DCO stabilization (<6 μs).
Peripherals are memory-mapped and accessible via all CPU instructions. The SD16_A module provides 16-bit sigma-delta conversion with internal VCC sense and temperature sensor support, while the DAC12 delivers voltage-output 12-bit conversion. Two software-configurable op-amps (OA0/OA1) provide programmable input multiplexing and feedback paths for analog front-end signal conditioning prior to ADC sampling.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430FG4250IRGZ | 16KB+256B Flash (vs. 24KB); identical peripherals, package, and pinout | Lower firmware capacity limits complex UI or sensor fusion algorithms | Select when application firmware fits within 16KB and cost sensitivity outweighs memory headroom |
| MSP430FG4270IRGZ | 32KB+256B Flash (vs. 24KB); otherwise identical architecture, peripherals, and RGZ-48 package | Higher memory enables advanced features like OTA updates or multi-sensor calibration tables | Select when future firmware expansion or feature-rich UI is required beyond 24KB footprint |
Compared with MSP430FG4250IRGZ and MSP430FG4270IRGZ, the MSP430FG4260IRGZT offers optimal balance of Flash capacity (24KB), identical analog/peripheral integration, and QFN-48 footprint - making it ideal for mid-complexity metering and sensor applications where memory headroom matters but 32KB is unnecessary overhead.

FAQ
What is the maximum LCD segment count supported by the MSP430FG4260IRGZT?
The MSP430FG4260IRGZT integrates the LCD_A peripheral supporting up to 56 segments using static, 2-MUX, 3-MUX, or 4-MUX configurations. With four common outputs (COM0–COM3) and 14 segment outputs (S0–S13), it achieves 56 segments in 4-MUX mode (14 × 4). This capability is confirmed in the functional block diagram and Terminal Functions table of SLAS556A.
Does the MSP430FG4260IRGZT support in-system programming without external hardware?
Yes, the MSP430FG4260IRGZT includes a UART-based bootstrap loader (BSL) that enables in-system flash programming using only P1.0 (TX) and P1.1 (RX) pins - no external programming voltage or JTAG debugger required. Password protection secures firmware updates, and BSL operation is documented in SLAA089 and SLAS556A Section 11.
What are the key power consumption specifications of the MSP430FG4260IRGZT in active and low-power modes?
The MSP430FG4260IRGZT draws 250 μA in active mode at 1 MHz and 2.2 V, 1.1 μA in standby mode, and 0.1 μA in off mode with RAM retention. These values are specified in the Absolute Maximum Ratings and Operating Modes sections of SLAS556A and are validated across the −40°C to 85°C temperature range.
Can the operational amplifiers in the MSP430FG4260IRGZT be configured for instrumentation amplifier topologies?
The MSP430FG4260IRGZT provides two independently configurable op-amps (OA0 and OA1) with software-selectable inputs (OA0I0/OA0I1/OA0I2; OA1I0/OA1I1/OA1I2) and feedback paths (OA0FB, OA1FB). While not a monolithic instrumentation amplifier, these op-amps can be externally wired and programmed to implement 2-op-amp or 3-op-amp IA topologies - confirmed in the Operational Amplifier section and OA Signal Connections table of SLAS556A.
Is the MSP430FG4260IRGZT pin-compatible with other members of the MSP430FG42x0 family?
Yes, the MSP430FG4260IRGZT shares identical pinout, package (RGZ-48), and peripheral mapping with MSP430FG4250IRGZ and MSP430FG4270IRGZ - differing only in Flash size (24KB vs. 16KB/32KB). This is explicitly stated in the "AVAILABLE OPTIONS" table and verified across Pin Designation (RGZ) and Terminal Functions sections of SLAS556A.
