Mixed-signal 16-bit MCU with on-chip LCD drive
It packs 32KB of Flash program memory and 256 bytes of RAM, but the real differentiator is the integrated analog front end: a 5-channel 16-bit ADC and a single 12-bit DAC, combined with a segment LCD driver. This peripheral set targets single-chip metering, portable instrumentation, and sensor-interface designs where the analog chain and a simple display share one die.
The supply range spans 1.8V to 3.6V, letting it run directly from two alkaline cells or a single Li-ion through the discharge curve — no external regulator needed until the cell drops below 1.8V.
On-chip analog and display peripheral set
The 16-bit SAR ADC with five input channels resolves sensor signals to 65,536 counts, enough for strain-gauge bridges or thermocouple linearization without an external converter. The 12-bit DAC provides a single analog output for set-point generation or waveform synthesis. A segment LCD controller drives a simple alphanumeric or custom-segment glass display directly, saving the cost and board area of a separate display driver IC. Brown-out detect and power-on reset are built in, so the BOM loses a supervisor IC.
48-pin SSOP — footprint and reflow
Housed in a 48-BSSOP package with 0.295-inch body width (48-SSOP), this is a standard fine-pitch surface-mount part. The 0.65 mm lead pitch needs a solder-paste stencil aperture sized per the IPC-7525 recommendation for SSOPs — typically a 1:1 pad-to-aperture ratio with a 0.1 mm step.
