Product details
Overview
MSP430F4152IPMR from Texas Instruments is an ultralow-power 16-bit RISC mixed-signal microcontroller featuring 16 KB Flash, 512 B RAM, integrated 144-segment LCD driver, 10-bit 200-ksps ADC, two USCI modules (UART/IrDA/SPI/I²C), and dual 16-bit timers - designed for battery-powered sensor interfaces and portable metering applications.
For engineers reviewing the MSP430F4152IPMR datasheet, MSP430F4152IPMR pinout, MSP430F4152IPMR application, or MSP430F4152IPMR equivalent, key selection criteria include its 1.8–3.6 V supply range, sub-μA standby current (0.9 μA), <6 μs wake-up time, on-chip LCD bias generation, and QFP-64 package with verified 48 I/O pins including dedicated COM/SEG LCD outputs.
Technical Context
The MSP430F4152IPMR integrates a digitally controlled oscillator (DCO) stabilized by FLL+ to deliver MCLK up to 8 MHz while enabling wake-up from LPM4 in under 6 μs. Its clock system provides independent ACLK (32.768 kHz crystal or VLO), SMCLK, and MCLK domains for precise peripheral timing control.
It implements two USCI modules: USCI_A0 supports UART with auto-baud detection and IrDA encoding/decoding, while USCI_B0 supports I²C master/slave and synchronous SPI - both disabled in 48-pin variants but fully functional in the 64-pin PM package of MSP430F4152IPMR.

Equivalent & Alternatives
The following parts are listed as comparable options for similar mixed-signal microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F4132IPMR | 8 KB Flash, same 512 B RAM, identical peripherals and pinout - reduced code capacity only. | Suitable for simpler firmware with smaller memory footprint; no change to PCB or driver stack required. | Select when application firmware fits within 8 KB and cost sensitivity outweighs future scalability needs. |
| MSP430FR4133IPMR | Ferroelectric RAM (FRAM) instead of Flash; 15 KB FRAM + 2 KB RAM; same 144-segment LCD, USCI, and ADC specs. | Enables ultra-low-power write-intensive logging (e.g., sensor history buffers) with near-zero write energy and unlimited endurance. | Choose for applications requiring frequent nonvolatile data writes or where Flash wear-out is a reliability concern over 10+ year deployments. |
Compared with MSP430F4152IPMR, the MSP430F4132IPMR offers identical functionality at lower memory cost, while the MSP430FR4133IPMR replaces Flash with FRAM to eliminate write latency and endurance limits - making it superior for cyclic data logging but requiring minor toolchain adaptation.

FAQ
What is the maximum operating frequency of the MSP430F4152IPMR?
The MSP430F4152IPMR supports a maximum MCLK frequency of 8 MHz, achieved using the internal digitally controlled oscillator (DCO) stabilized by the FLL+ module with a 32.768 kHz crystal reference.

Does the MSP430F4152IPMR support I²C communication?
Yes, the MSP430F4152IPMR supports I²C communication via USCI_B0 module, which is fully enabled in the 64-pin QFP (PM) package. It operates as I²C master or slave with standard-mode (100 kbps) and fast-mode (400 kbps) support, using P6.1 (SCL) and P6.2 (SDA) pins.
How many LCD segments can the MSP430F4152IPMR drive directly?
The MSP430F4152IPMR integrates the LCD_A peripheral capable of driving up to 144 segments in static, 2-MUX, 3-MUX, or 4-MUX configurations. It uses dedicated COM0–COM3 and SEG pins mapped across Ports P2–P7, eliminating external LCD driver ICs for displays up to 36×4 pixels.
Is the MSP430F4152IPMR pin-compatible with other MSP430F41x2 variants?
Yes, the MSP430F4152IPMR shares identical pinout and electrical characteristics with MSP430F4132IPMR in the 64-pin QFP package. Both devices use the same PM package drawing, terminal functions, and I/O mapping - enabling drop-in replacement where firmware fits within 8 KB Flash.
