Texas Instruments 64-LQFP MSP430FR59891IPMR

The MSP430FR59891IPMR is a microcontroller unit (MCU) from Texas Instruments, part of the MSP430FR59xx series with an ultra-low power (ULP) FRAM-based platform. It features a Real-Time Clock (RTC) driven by a 3.7pF crystal oscillator and offers a combination of low-power operation, embedded non-volatile FRAM memory, and various peripherals for communication and control. The device comes in a LQFP package and supports a wide voltage range from 1.8V to 3.6V, providing low active mode current consumption (e.g., 280μA at 1MHz and 2.2V) and ultra-low standby mode current. For detailed specifications, refer to the official MSP430FR58xx/59xx/6xx User's Guide.
