Product details

What this 16-bit MCU brings to the BOM

The Texas Instruments MSP430F5259IRGCT is a 16-bit MSP430 CPUXV2 microcontroller running at 25 MHz, with 128 KB of Flash and 32 KB of RAM. The 25 MHz clock rate and 32 KB RAM support a Modbus RTU stack and a PID loop simultaneously.

Temperature grade and deployment environment

Peripherals and on-chip resources

The 12-channel 10-bit ADC covers basic analog sensing — enough for temperature, current, or voltage monitoring on a control board, but not for high-resolution data acquisition where a 12-bit or 16-bit external ADC would be specified. For IrDA or high-speed UART, a crystal may still be advisable.

TI lists the MSP430F5259IRGCT as Active. We source this part through independent distribution and quote it to order against an RFQ.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430F5259IRGCT in this component family?

Within the MSP430F5xx series, the MSP430F5258 and MSP430F5257 share the same 64-VQFN footprint and peripheral set but differ in Flash/RAM density. Check the specific memory and I/O requirements against the family selector guide before substituting.

What is MSP430F5259IRGCT's listed speed (25 MHz) on this component line?

The core runs at 25 MHz maximum. That is the CPU clock rate for the MSP430 CPUXV2 — enough for real-time control loops and protocol handling without external oscillators in many cases.
