Product details
Overview
MSP430F5333IPZ from Texas Instruments is a 16-bit ultra-low-power mixed-signal microcontroller with 128 KB flash, 10 KB RAM, integrated 3.3-V LDO, 12-bit ADC (200 ksps, 16 channels), dual 12-bit DACs, two USCI modules (UART/IrDA/SPI/I²C), four 16-bit timers, RTC with battery backup, and 74 GPIO pins - deployed in portable sensor systems and battery-powered digital meters.
For engineers reviewing the MSP430F5333IPZ datasheet, MSP430F5333IPZ pinout, MSP430F5333IPZ application, or MSP430F5333IPZ equivalent, key selection criteria include standby current (1.8 µA at 2.2 V), wake-up time (3 µs), ADC resolution and sampling rate, DAC synchronization capability, and LQFP-100 package compatibility with industrial PCB layouts.
Technical Context
The MSP430F5333IPZ implements a 16-bit RISC CPUXV2 core with constant generators and hardware multiplier supporting 32-bit operations. Its unified clock system integrates FLL stabilization, VLO/REFO internal sources, and support for 32-kHz XT1 and up to 32-MHz XT2 crystals - enabling precise timing control across five low-power modes.
Power management includes programmable LDO core regulation, supply supervision, brownout detection, and dedicated RTC_B module with alarm and VBAK backup switching. Peripheral interconnect uses 6-channel DMA and port mapping controllers to decouple I/O assignment from physical pin layout.

FAQ
What is the maximum operating frequency of the MSP430F5333IPZ?
The MSP430F5333IPZ supports a maximum system clock frequency of 20 MHz, achieved via its digitally controlled oscillator (DCO) or external high-frequency crystal (XT2) up to 32 MHz. This allows deterministic real-time execution for time-critical tasks such as motor control loops or high-speed sensor sampling - all while maintaining ultra-low active-mode current of 270 µA/MHz at 3.0 V.
Does the MSP430F5333IPZ include an integrated voltage regulator?
Yes, the MSP430F5333IPZ integrates a fully functional 3.3-V low-dropout (LDO) regulator with programmable core voltage control, supply voltage supervision, and brownout detection. The LDO accepts 3.3–3.6 V on LDOI and delivers regulated VCORE and LDOO - eliminating the need for external regulators in most battery- or USB-powered designs.
How many analog input channels does the ADC support on the MSP430F5333IPZ?
The MSP430F5333IPZ features the ADC12_A module with 16 total input channels: 12 external analog inputs (A0–A11) and 4 internal sources (temperature sensor, VCC/2, VeREF+, and VREF+). All channels are accessible via autoscan mode, enabling continuous multi-sensor acquisition without CPU overhead - critical for energy-constrained applications.
Can the MSP430F5333IPZ operate from a single 3.0-V battery?
Yes, the MSP430F5333IPZ operates across a supply range of 1.8 V to 3.6 V, making it fully compatible with standard 3.0-V lithium coin cells or two-cell alkaline batteries. At 3.0 V, its LPM3 standby current is 2.1 µA, LPM3.5 RTC mode draws 1.1 µA, and LPM4.5 shutdown consumes only 0.3 µA - ensuring multi-year operation in always-on sensing applications.
Is the MSP430F5333IPZ pin-compatible with other devices in the F533x family?
Yes, the MSP430F5333IPZ in the LQFP-100 (PZ) package shares identical pinout and electrical characteristics with MSP430F5335IPZ, MSP430F5336IPZ, and MSP430F5338IPZ - enabling direct substitution within the same footprint. Differences lie solely in flash/RAM size and DAC presence, allowing scalable firmware reuse across variants without hardware changes.
