What this part is and where it fits
Four 16-bit sigma-delta ADCs handle multiple sensor inputs without external muxing, and the peripheral set includes a brown-out reset, POR, PWM, and a watchdog timer. Communication interfaces cover I²C, SPI, UART/USART, IrDA, and LINbus — enough to talk to most field sensors and serial displays. Operating temperature range spans -40 to 85°C. Supply voltage runs from 1.8 V to 3.6 V.
Lifecycle and sourcing reality
What the key ratings mean for your BOM
The 16 MHz clock is enough for the LCD scan rate and the 16-bit ADC conversions in a typical metering loop — you're not pushing bus timing margins. The 60 KB Flash holds a modest firmware image with room for a calibration table and a few field-upgrade slots. The 2.5 KB RAM is tight: it forces careful buffer sizing for the LCD frame buffer and the communication stacks. If your application needs more RAM for data logging, you'll want to step up to a sibling with larger SRAM. The 100-LQFP package (14x14 mm) gives 72 I/O lines, enough to interface with a keypad, a few sensors, and a parallel LCD data bus. The surface-mount footprint is standard for automated assembly lines.
Integration note
Internal oscillator eliminates the external crystal for the CPU clock. Brown-out reset and POR are on-chip. The 4x16-bit ADC inputs are multiplexed internally.
