Product details
Overview
MSP430F4270IRGZT from Texas Instruments is an ultralow-power 16-bit mixed-signal microcontroller featuring 32KB+256B Flash, 256B RAM, a 16-bit sigma-delta ADC with internal reference and five differential analog inputs, a 12-bit DAC, Timer_A3 with three capture/compare registers, and integrated LCD driver supporting up to 56 segments - deployed in battery-powered sensor systems and handheld meters.
For engineers reviewing the MSP430F4270IRGZT datasheet, MSP430F4270IRGZT pinout, MSP430F4270IRGZT application, or MSP430F4270IRGZT equivalent, key selection criteria include active-mode current (250 μA @ 1 MHz, 2.2 V), standby current (1.1 μA), wake-up latency (<6 μs), LCD segment drive capability (56 seg), and QFN-48 package compatibility with space-constrained portable designs.
Technical Context
The MSP430F4270IRGZT 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 (up to 8 MHz), and SMCLK for peripheral timing.
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 inputs, while DAC12 delivers 12-bit voltage output with selectable 8-/12-bit resolution - both operating from the same AVCC/AVSS supply domain.

FAQ
What is the maximum operating frequency of the MSP430F4270IRGZT at 3.6 V?
The MSP430F4270IRGZT supports a maximum system clock (MCLK) frequency of 8 MHz at 3.6 V supply, as specified in the recommended operating conditions. This limit is enforced by the FLL+ module's DCO stability constraints and ensures reliable execution of 16-bit RISC instructions with 125-ns cycle time. At lower voltages (e.g., 1.8 V), the max frequency reduces to 4.15 MHz to maintain timing margins.
Does the MSP430F4270IRGZT support JTAG debugging and in-system programming?
Yes, the MSP430F4270IRGZT fully supports IEEE 1149.1 JTAG debugging and programming via TCK, TMS, TDI, and TDO pins (RGZ pins 46, 45, 44, 43). It enables full-speed emulation, flash erase/write, and boundary-scan testing. The device also supports serial bootstrap loader (BSL) programming via UART on P1.0/P1.1 - providing dual-path programming flexibility.
How many LCD segments can the MSP430F4270IRGZT drive, and what multiplexing configurations are supported?
The MSP430F4270IRGZT integrates the LCD_A peripheral capable of driving up to 56 segments using static, 2-MUX, 3-MUX, or 4-MUX configurations. It provides four common outputs (COM0–COM3) and dedicated segment I/O on ports P2, P5, and P6. Contrast is software-adjustable via internal charge pump regulation - eliminating need for external bias components.
What analog input channels does the 16-bit sigma-delta ADC (SD16_A) support on the MSP430F4270IRGZT?
The SD16_A module on the MSP430F4270IRGZT supports five differential analog input pairs: A0+/-, A1+/-, A2+/-, A3+/-, and A4+/- - mapped to P6.0–P6.3, P1.7/P1.6, P1.5/P1.4, P1.2/P1.3 respectively. It also includes internal VCC sense and temperature sensor channels, all referenced to the internal 1.2-V bandgap or external VREF.
Is the MSP430F4270IRGZT pin-compatible with other devices in the MSP430F42x0 family?
Yes, the MSP430F4270IRGZT is pin-compatible with MSP430F4250IRGZ and MSP430F4260IRGZ in the RGZ (48-pin QFN) package. All share identical pin functions, electrical characteristics, and peripheral mappings - enabling hardware reuse across variants. Only Flash/RAM sizes differ; no PCB redesign is required when upgrading within this package option.
