Metering-grade MCU with on-chip LCD and sigma-delta converters
This combination targets energy metering, flow measurement, and industrial sensor applications where precision low-frequency measurement and a local display are needed without external components.
What the 4x24-bit sigma-delta ADC means for your measurement chain
Four independent 24-bit sigma-delta converters let this single chip handle multi-phase power metering or multi-channel sensor acquisition simultaneously. The 24-bit resolution gives the dynamic range to resolve small signals in the presence of large DC offsets — think current transformers on a power line or bridge-type pressure sensors. You still get the 8-channel 10-bit SAR ADC for faster auxiliary measurements like temperature or supply monitoring.
LCD driver saves a display controller and board space
The integrated LCD driver can directly drive a segmented glass LCD — common in utility meters, thermostats, and panel instruments — without a separate display controller chip. That means one fewer IC to source, one fewer serial bus to route, and a simpler BOM for cost-sensitive metering designs.
128-LQFP package and industrial temperature range
Housed in a 128-LQFP with a 20x14 mm body, this part brings out 90 I/O pins — enough for a parallel LCD bus, multiple serial ports, and sensor interface lines. Supply voltage spans 1.8V to 3.6V, so it can run from a single lithium cell or a 3.3V regulated rail.
