Product details

16-bit MSP430 MCU with 48 KB Flash and integrated ADC

The MSP430F148IRTDR: The 16-bit microcontroller from the MSP430x1xx family runs at 8 MHz and carries 48 KB of Flash program memory plus 2K x 8 of RAM. Eight 12-bit ADC channels bring analog sensor inputs onto the die, and the SPI and UART/USART interfaces handle serial communication. The part is specified over the industrial temperature range of -40°C to 85°C.

48 KB Flash and 8 MHz core — what they mean for the BOM

The 48 KB Flash sets the firmware budget. The 8 MHz clock is the throughput ceiling.

Frequently asked questions

What is the operating voltage range of MSP430F148IRTDR?

The supply voltage range is 1.8 V to 3.6 V, covering both 3.3 V and 1.8 V logic rails commonly found in battery-powered and industrial designs.

What is MSP430F148IRTDR's listed speed?

The core runs at 8 MHz, which is the maximum clock frequency for this MSP430x1xx device. That sets the instruction throughput and the achievable baud rates on the UART and SPI interfaces.

What is a direct replacement for MSP430F148IRTDR?

No official direct replacement is listed for this exact order code. A pin-compatible alternative would need to be evaluated within the MSP430x1xx family, but any swap requires board-level validation of Flash size, RAM, and peripheral set.
