Product details

FRAM-based 16-bit MCU for industrial sensing and control

It combines 64 KB of FRAM program memory with 2 KB of SRAM, 51 general-purpose I/O lines, and an 8-channel 12-bit ADC, all in a 64-pin LQFP package measuring 10x10 mm.

Brown-out detect and POR are integrated, so the reset circuitry is handled on-chip.

Peripheral set for serial communication and analog front ends

The 8-channel 12-bit ADC can sample multiple analog inputs without an external mux, and the DMA engine moves data without CPU intervention, which helps keep the core asleep longer in low-power applications. PWM outputs support motor control or LED dimming directly.

Frequently asked questions

What is the closest pin-compatible alternative to MSP430FR59721IPMR in the MSP430 FRAM family?

Within the MSP430 FRAM series, devices sharing the same 64-LQFP footprint and base pinout include the MSP430FR5969 and MSP430FR5994 families. The MSP430FR5969 offers 64 KB FRAM and 2 KB SRAM with similar peripherals, while the MSP430FR5994 steps up to 256 KB FRAM. Verify the specific memory and peripheral differences against your firmware requirements before substituting.

What is MSP430FR59721IPMR's listed speed?

The MSP430 CPUXV2 core is rated for 16 MHz operation. This is the maximum clock frequency; actual throughput depends on flash wait states and the instruction mix.
