It includes a 14-channel 10-bit ADC. ## FRAM program memory — field updates without wear limits 4 KB of FRAM replaces both Flash and EEPROM in one block. It supports over 10¹⁵ write cycles — effectively unlimited for field firmware updates — and writes at bus speed without erase cycles. That means no wear-leveling code, no write-page buffers, and no 10 ms erase delay. For a product that ships with factory firmware and receives OTA patches in the field, FRAM simplifies the memory management layer. ## NRND — plan the last-time buy now TI lists the MSP430FR5731IRHAT as NRND.","metaTitle":"TI MSP430FR5731IRHAT 16-bit MCU, 24 MHz, 4KB FRAM, 40-VQFN","metaDescription":"Texas Instruments MSP430FR5731IRHAT 16-bit MCU with 24 MHz core, 4KB FRAM, 14x10b ADC, -40°C to 85°C.
