Product details

8 MHz core — what it means for the control loop

The 8 MHz clock rate is typical for the MSP430x4xx series and sufficient for real-time display updates, sensor polling at kilohertz rates, and low-speed communication buses. It is not a part for high-speed DSP or motor-field-oriented control; the strength is ultra-low-power operation with deterministic interrupt response for event-driven metering and user-interface tasks.

Lifecycle: obsolete — plan the BOM transition

Officially marked obsolete by Texas Instruments. No last-time-buy window or successor part number is listed in the available records.

Peripheral set — LCD drive and serial flexibility

The integrated LCD controller drives segment displays directly, eliminating a separate display driver IC. The serial interface block supports I²C, SPI, and UART, plus IrDA and LINbus for industrial or automotive sub-networks. With 40 I/O lines and an 8-channel 10-bit ADC, the part can handle a mix of digital inputs, analog sensor readings, and display segments in a single-chip metering or control panel design.

Frequently asked questions

What is the replacement for MSP430F4152IRGZ?

No official replacement part number is listed. A pin-compatible migration within the MSP430x4xx family should be evaluated; the MSP430F4152IPZ is a known variant but differs in package and must be checked for fit. For existing BOM lines, the part is available through independent distribution.

What are the specifications of MSP430F4152IRGZ?

The MSP430F4152IRGZ is a 16-bit MCU with an 8 MHz MSP430 CPU16 core, 16 KB Flash program memory, 512 x 8 bytes RAM, 40 I/O lines, an integrated LCD driver, an 8-channel 10-bit ADC, and serial interfaces including I²C, SPI, UART, IrDA, and LINbus. It operates from 1.8 V to 3.6 V over the industrial temperature range of -40°C to 85°C, in a 48-VFQFN exposed-pad package.

Is MSP430F4152IRGZ equivalent to MSP430F4152IPZ?

The MSP430F4152IPZ is a known variant of the same base product number MSP430F4152, but it uses a different package. The IRGZ is in a 48-VFQFN, while the IPZ uses a different package type. Pin compatibility and temperature grade must be verified against the specific BOM before substitution.
