Product details

Connectivity and analog integration

On the serial side, this part covers I2C, SPI, UART/USART, IrDA, and LIN — so it can talk to common sensor modules, memory chips, and actuator drivers without extra protocol converters. The 16-channel 12-bit ADC handles analog inputs like thermocouples, potentiometers, or current-sense resistors directly. Brown-out detect, POR, and a watchdog timer are built in, which simplifies power-up sequencing and fault recovery in remote or unattended gear.

Temperature grade and deployment

Rated for -40°C to 85°C. Supply range is 1.8 V to 3.6 V.

Lifecycle and sourcing

Frequently asked questions

Is MSP430F5333IPZR obsolete?

Yes, the MSP430F5333IPZR is in end-of-life (EOL hot) status. TI has announced discontinuation, so it is a last-time-buy part. Secure stock or plan a replacement before supply dries up.

Does MSP430F5333IPZR have I2C and SPI connectivity?

Yes, this MCU includes I2C, SPI, UART/USART, IrDA, and LIN interfaces, so it can connect to most common sensors, memory, and peripheral devices.

What is the maximum clock speed of MSP430F5333IPZR?

The MSP430F5333IPZR runs at 20 MHz, which is a mid-range speed for the MSP430 family — enough for control loops and sensor fusion without excessive power draw.

Does MSP430F5333IPZR have a built-in ADC?

Yes, it has a 16-channel 12-bit ADC on-chip, so you can read analog signals like temperature, pressure, or current directly without an external converter.
