Product details

FRAM-based 16-bit MCU for low-power sensing and control

The device integrates 2K x 8 of RAM, an 8-channel 10-bit ADC, and serial interfaces including I²C, SPI, and UART.

Why FRAM matters for the BOM

FRAM combines the non-volatility of Flash with the write speed and low power of SRAM. For the MSP430FR2533IRHBT, this means the 15.5 KB program memory can be written byte-by-byte at full bus speed without erase cycles, making it ideal for frequent data logging, configuration updates, or over-the-air firmware patches. The 2K x 8 RAM handles stack and scratchpad variables.

Housed in a 32-VFQFN exposed-pad package (5x5 mm body), the MSP430FR2533IRHBT is a surface-mount device. The supplier device package is 32-VQFN (5x5).
