FRAM-based MCU with built-in segment LCD drive
Its program memory is 32 KB of FRAM — a non-volatile memory that combines the speed of SRAM with the non-volatility of Flash, and supports near-infinite write endurance without wear-leveling.
Peripheral set for sensor-rich, display-centric designs
On-chip peripherals include a brown-out detect/reset circuit, DMA controller, POR, PWM timer, and watchdog timer. The 52 general-purpose I/O lines provide ample headroom for keypads, external sensors, and memory expansion. An internal oscillator reduces external BOM count, though an external crystal can be used for tighter timing budgets.
12-bit ADC and data conversion for analog front ends
An 8-channel, 12-bit successive-approximation ADC handles analog inputs from thermistors, strain gauges, or current shunts. The 2 KB of SRAM (2K x 8) provides scratchpad for ADC results and stack operations, while the FRAM can store calibration constants and logged data without the endurance limits of EEPROM.
