Product details

8 MHz 16-bit MCU with 8 KB Flash — what the spec means for the BOM

The 256 x 8 RAM is the tightest constraint on this part — it limits stack depth and buffer count, so firmware must be sized for data-light tasks like sensor polling, relay sequencing, or simple UART protocol handling.

Peripherals and connectivity for basic control tasks

Connectivity is limited to SPI and UART/USART, with 22 general-purpose I/O brought out to the 28-TSSOP package. The 8-channel 10-bit ADC covers analog sensor input without an external converter.

ROHS3 compliant, so no exemption expiry to track.

Frequently asked questions

What is the maximum clock speed of MSP430F1232IPW?

The core is rated for 8 MHz maximum. At that speed, the Flash wait state must be configured correctly to avoid instruction fetch faults — refer to the device errata for the required setting.

Does MSP430F1232IPW require an external oscillator?

No. The part includes an internal oscillator, so many designs can operate without an external crystal. If tighter timing accuracy is needed, an external clock source can be used.

Is MSP430F1232IPW RoHS compliant?

Yes, it is ROHS3 compliant per the TI listing, meaning it meets the current RoHS directive without exemptions.
