Product details

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

FRAM writes at bus speed, consumes negligible power in standby, and retains data without a battery—making this MCU a fit for energy-harvesting sensors, industrial data loggers, and battery-operated field instruments. The 16 MHz clock rate supports real-time control loops and serial communication without the overhead of external memory.

Serial interfaces and analog integration

A 12-channel 12-bit ADC is on-chip, reducing external analog front-end components. The 31 general-purpose I/O lines are enough for keypad scanning, LED driving, and parallel sensor arrays in a compact 38-TSSOP footprint.

Internal oscillator and brown-out reset simplify the power-on sequence.

Lifecycle and sourcing posture

No official replacement or second-source alternate is documented in the available records.
