FRAM mixed-signal MCU for low-power sensing and control
On-chip peripherals include a 12-channel 12-bit ADC, brown-out reset, POR, PWM timer, and watchdog timer — enough to handle a sensor front-end and a small control loop without external supervisory ICs. The 31 GPIOs and serial interfaces (I²C, IrDA, SCI, SPI, UART/USART) cover the common bus protocols for connecting an LCD, radio module, or external EEPROM. The device is rated over the -40 °C to 85 °C industrial temperature range and comes in a 38-pin TSSOP package (6.10 mm body width), suited for outdoor telecom cabinets, factory automation panels, and under-hood automotive auxiliary electronics where the environment stays below 85 °C ambient.
48 KB FRAM — what it means for field updates and data logging
The 2 KB SRAM is sized for a small call stack and temporary buffers. Most real-time data handling should target FRAM directly for non-volatile storage — the 48 KB program space doubles as NVRAM once the code footprint is fixed.
