FRAM memory — what it changes for the BOM
The 15.5 KB FRAM writes at bus speed with no erase cycle. This eliminates the need for external EEPROM or battery-backed SRAM for data logging.
Industrial temperature rating and package
The -40°C to 85°C operating range covers industrial and outdoor telecom enclosures. The 24-ball DSBGA package requires controlled soldering and X-ray inspection.
Connectivity and analog
Serial connectivity covers I²C, SPI, UART/USART, IrDA, and SCI — enough to talk to common sensors, radios, and serial EEPROMs. The 8-channel 10-bit ADC handles analog inputs like thermistors, potentiometers, or current-sense resistors without an external converter. Brown-out detect and POR are on-chip, so external supervisor ICs are optional.
