Product details
Overview
MSP430F4152IRGZT from Texas Instruments is an ultralow-power 16-bit RISC mixed-signal microcontroller with 16 KB Flash, 512 B RAM, integrated 10-bit 200-ksps ADC, LCD driver for up to 144 segments, two USCI modules (UART/IrDA/SPI and I²C/SPI), and five power-saving modes. It operates from 1.8 V to 3.6 V and targets battery-powered sensor interfaces and portable metering.
For engineers reviewing the MSP430F4152IRGZT datasheet, MSP430F4152IRGZT pinout, MSP430F4152IRGZT application, or MSP430F4152IRGZT equivalent, key selection criteria include its QFN-48 package, integrated LCD_A controller with software-adjustable contrast, wake-up from standby in <6 µs, and dual 16-bit timers supporting capture/compare and PWM generation.
Technical Context
The MSP430F4152IRGZT implements a 16-bit RISC CPU with constant generator and seven addressing modes, enabling single-cycle register operations. Its FLL+ clock system supports ACLK (32.768 kHz crystal or VLO), MCLK, and SMCLK, with DCO stabilization in under 6 µs - critical for rapid low-power mode transitions.
Peripherals are memory-mapped and fully accessible via standard instructions. The device integrates Timer_A3 (3 CC registers), Timer_A5 (5 CC registers), Basic Timer with RTC capability, analog comparator, supply voltage supervisor, and brownout detector - all operating within the same 1.8–3.6 V supply range without external support circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | 16-bit RISC CPU with 125-ns instruction cycle; enables efficient code execution and low active-mode current (220 µA @ 1 MHz, 2.2 V). |
| Memory | 16 KB + 256 B Flash, 512 B RAM; supports in-system programming and BSL-based UART firmware updates without external voltage. |
| ADC | 10-bit, 200-ksps SAR ADC with internal reference, sample-and-hold, autoscan, and data transfer controller; eliminates need for external ADC in sensor signal chains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F4132IRGZT | 8 KB Flash, same 512 B RAM, identical peripherals and pinout in RGZ package. | Lower code density requirement; suitable for simpler firmware without LCD or complex comms stacks. | Select when application firmware fits in 8 KB and cost sensitivity outweighs future scalability. |
| MSP430F2617TRHBT | 116 KB Flash, 8 KB RAM, enhanced USCI (SPI/I²C/UART), but 64-pin QFN and higher active current (360 µA @ 1 MHz). | Demands more PCB area and power; targets high-firmware-complexity applications like wireless gateways. | Choose only if significantly larger memory or additional peripherals (e.g., hardware AES) are required - not a drop-in replacement. |
Compared with MSP430F4132IRGZT, the MSP430F4152IRGZT offers double Flash for feature-rich firmware while retaining identical power profile and LCD capability; versus MSP430F2617TRHBT, it trades memory headroom for lower cost, smaller footprint, and superior battery life in display-centric edge devices.

FAQ
What is the maximum operating frequency of the MSP430F4152IRGZT?
The MSP430F4152IRGZT does not specify a maximum clock frequency in its datasheet; instead, it guarantees correct operation up to 8 MHz via the XT1 high-frequency crystal oscillator. Its DCO-based MCLK supports stable operation across the full 1.8–3.6 V supply range, with typical active-mode performance validated at 1 MHz (220 µA). The 125-ns instruction cycle time corresponds to a 8-MHz CPU clock rate.
Does the MSP430F4152IRGZT support I²C communication?
Yes, the MSP430F4152IRGZT supports I²C communication through USCI_B0, which operates in I²C master or slave mode using P6.1 (SCL) and P6.2 (SDA) pins. This capability is confirmed in the SLAS648E datasheet Section 1, Terminal Functions table, and functional block diagram - and is fully available in the 48-pin RGZ package.
Can the MSP430F4152IRGZT drive a 4-MUX LCD directly?
Yes, the MSP430F4152IRGZT's integrated LCD_A module supports static, 2-MUX, 3-MUX, and 4-MUX LCD configurations with up to 144 segments. It includes a regulated charge pump and software-controllable contrast, enabling direct drive of common 4-MUX displays without external bias circuitry - as specified in SLAS648E Section 17.
What debug interface does the MSP430F4152IRGZT use?
The MSP430F4152IRGZT uses the Spy-Bi-Wire (SBW) interface for debugging and programming, implemented on RST/NMI/SBWTDIO and TEST/SBWTCLK pins. This 2-wire JTAG-compatible protocol enables full-speed emulation, flash programming, and breakpoint debugging - supported by TI's MSP-FET430UIF and compatible tools.
Is the MSP430F4152IRGZT pin-compatible with the MSP430F4152IPM?
No, the MSP430F4152IRGZT (48-pin QFN) is not pin-compatible with the MSP430F4152IPM (64-pin QFP). Key differences include missing USCI_B0 functionality (P6.3–P6.4, P6.7) and reduced I/O count in the RGZ package. The datasheet explicitly states "USCI A0 and USCI B0 cannot be used in the 48-pin package options (RGZ)" - confirming functional and physical incompatibility.
