Product details

What this 16-bit MCU brings to a panel or field controller

Connectivity covers I²C, IrDA, SPI, and UART/USART, so it talks to common sensor bridges, serial displays, and radio modules directly. If your application sits in a conditioned server room, that is headroom; if it lives on a factory floor near a washdown station, the temperature grade is comfortable.

Flash and RAM — sizing the BOM for firmware updates

128 KB Flash and 8 KB RAM. Flash supports in-application programming via bootloader.

The 37 I/O lines are enough to drive a 16x2 character LCD, read a dozen limit switches, and still leave a few pins for a rotary encoder and a buzzer. Each I/O is 5 V tolerant on the input side, which simplifies interfacing with older 5 V logic or sensors without level shifters.

Lifecycle and sourcing — still active, no LTB pressure

Frequently asked questions

What is the speed rating of MSP430F5234IRGZR?

The CPU core runs at 25 MHz. That is the maximum clock frequency for the MSP430 CPUXV2 core on this device, governing instruction throughput for real-time control loops and communication timing.
