16 MHz CPU and FRAM — what they mean for the BOM
The 16 MHz clock is fast enough for real-time control loops, sensor polling, and updating a segment LCD in a metering application. The FRAM program memory is the standout feature: it writes at near-SRAM speed and endures over 10¹⁵ write cycles, so firmware can log data directly to program space without wearing out the memory. That eliminates the need for a separate serial EEPROM in many designs — one fewer line item on the BOM.
Industrial temperature grade and package
Rated for -40°C to 85°C ambient, the part suits factory-floor controllers, outdoor telecom gear, and other environments where the PCB sees temperature swings. The 48-TSSOP package (6.10 mm body width) is a surface-mount footprint that fits compact two-layer boards without requiring fine-pitch assembly. Supply voltage spans 1.8 V to 3.6 V, so a single Li-ion cell or two alkaline cells can power the system directly.
