Mixed-signal MCU with LCD drive and analog front-end
It runs at 8 MHz and integrates 92 KB of Flash program memory alongside 4K x 8 of RAM. This part is notable for its on-chip analog peripherals: a 12-channel 12-bit ADC and two 12-bit DACs, plus a direct LCD driver, making it a single-chip solution for metering, portable medical, and sensor-interface designs that need a display and analog I/O without external components.
92 KB Flash and 4K RAM — sizing the firmware and data buffer
The 92 KB Flash (organized as 92K x 8 plus 256 bytes) provides enough code space for complex control loops, communication stacks (I²C, SPI, UART/USART, LIN, IrDA), and the LCD driver firmware. The 4K x 8 RAM handles moderate data buffering for the ADC channels and DMA transfers. If your application logs sensor data or runs a real-time OS, check whether the RAM fits your heap and stack budget — this is a mid-range capacity, not a high-end part.
12-bit ADC and DAC — analog integration on-chip
With a 12-channel, 12-bit ADC and two 12-bit DACs, this MCU can directly interface to analog sensors (temperature, pressure, current) and output analog control signals (set-points, transducer drive) without external converters. The 12-bit resolution is adequate for many industrial and medical sensing applications.
Industrial temperature range and BGA package
The 113-VFBGA package (7x7 mm BGA Microstar Junior) saves board area but demands careful PCB layout — BGA rework and X-ray inspection are standard for this footprint. The surface-mount BGA is not hand-solder friendly; plan for a reflow oven and stencil.
