Product details
Overview
MSP430F6433IZCAR from Texas Instruments is an ultra-low-power 16-bit RISC microcontroller with 128 KB Flash, 10 KB RAM, integrated 12-bit ADC (12 external + 4 internal channels), dual 12-bit DACs, LCD driver for up to 160 segments, RTC, four 16-bit timers, two USCI modules (UART/IrDA/SPI/I²C), and hardware multiplier - designed for battery-powered sensor systems and portable meters.
For engineers reviewing the MSP430F6433IZCAR datasheet, MSP430F6433IZCAR pinout, MSP430F6433IZCAR application, or MSP430F6433IZCAR equivalent, key selection criteria include standby current (1.8 µA at 3.0 V), wake-up time (3 µs), LDO-integrated 3.3-V power system, and 74 I/O pins in 100-pin LQFP package - critical for low-energy embedded measurement designs.
Technical Context
The MSP430F6433IZCAR implements a unified clock system with FLL stabilization, VLO/REFO internal oscillators, and support for 32-kHz XT1 and up to 32-MHz XT2 crystals. Its flexible power management includes programmable core voltage regulation via integrated LDO and brownout detection with hysteresis.
It features six-channel DMA, hardware multiplier supporting 32-bit operations, and peripheral mapping across 10 I/O ports (P1–P9, PJ, PU). The device supports real-time clock backup via VBAT and includes dedicated LCD bias generation with contrast control - enabling direct drive of segmented displays without external components.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar ultra-low-power microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MSP430F6436IPZ | 256 KB Flash, 18 KB RAM, same peripherals and package - no DACs | Higher firmware capacity for complex protocols or OTA updates; lacks DAC functionality required for analog stimulus generation | Select when firmware size exceeds 128 KB and DACs are unnecessary. |
| MSP430F6435IPZ | 256 KB Flash, 18 KB RAM, same peripherals except no DACs - identical pinout and power specs | Same memory headroom as F6436 but shares F6433's absence of DACs; differs only in Flash/RAM allocation | Prefer when larger memory is needed and DAC-free design is confirmed. |
Compared with MSP430F6433IZCAR, the F6436IPZ offers double Flash/RAM for feature-rich firmware but removes DACs essential for analog control loops; the F6435IPZ retains identical DAC omission while increasing memory - making MSP430F6433IZCAR the sole choice among these three for designs requiring dual 12-bit voltage-output DACs in LQFP.

FAQ
What is the maximum operating frequency of the MSP430F6433IZCAR?
The MSP430F6433IZCAR supports a maximum system clock frequency of 20 MHz, achieved via its digitally controlled oscillator (DCO) with FLL stabilization. This frequency is fully supported across all operating voltage ranges (1.8 V to 3.6 V) and enables deterministic real-time execution for time-critical sensor sampling and control loops in the MSP430F6433IZCAR.
Does the MSP430F6433IZCAR include an integrated LCD driver?
Yes, the MSP430F6433IZCAR integrates the LCD_B module capable of driving up to 160 segments with built-in charge pump, contrast control, and programmable bias voltage generation. It supports static, 2-mux, 3-mux, and 4-mux LCD configurations - eliminating external display controllers and reducing bill-of-materials cost in portable instrumentation using the MSP430F6433IZCAR.
How many analog input channels does the ADC in the MSP430F6433IZCAR support?
The MSP430F6433IZCAR features a 12-bit ADC12_A module with 16 total input channels: 12 external analog inputs (A0–A11) and 4 internal sources (temperature sensor, VCC/2, VeREF+, and VMID). Channel selection is managed via autoscan mode or software-controlled register writes - providing flexible signal acquisition for multi-sensor systems built around the MSP430F6433IZCAR.
What low-power modes are available on the MSP430F6433IZCAR?
The MSP430F6433IZCAR supports five low-power modes (LPM0–LPM4), including LPM3 (1.8 µA at 3.0 V with RTC active) and LPM4.5 (0.3 µA shutdown). All modes retain full RAM content except LPM4.5, and wake-up occurs in 3 µs from LPM3 - enabling rapid response to external interrupts or RTC alarms in battery-constrained applications using the MSP430F6433IZCAR.
Is the MSP430F6433IZCAR pin-compatible with other devices in the MSP430F643x family?
Yes, the MSP430F6433IZCAR shares identical pinout and package (100-pin LQFP PZ) with MSP430F6435IPZ, MSP430F6436IPZ, and MSP430F6438IPZ - allowing drop-in replacement where peripheral requirements align. However, DAC presence, Flash/RAM size, and specific peripheral enablement differ; always verify functional compatibility against the target application before substitution in designs using the MSP430F6433IZCAR.
