Product details

Six 24-bit sigma-delta ADCs and an LCD driver on one die

Its standout feature is the six 24-bit sigma-delta ADCs, purpose-designed for polyphase energy metering and multi-channel sensor acquisition. An integrated LCD driver lets the chip drive a segment display directly, cutting the component count on a meter or panel controller.

Peripheral set for metering and industrial control

Connectivity covers I²C, IrDA, LINbus, SPI, and UART/USART — enough to talk to external sensors, displays, and a host controller. With 62 I/O lines in a 100-pin LQFP (14x14 mm body), there is room for parallel interfaces and control signals without multiplexing.

Frequently asked questions

Does MSP430F67681IPZ have a built-in LCD driver?

Yes, the LCD peripheral is integrated on-chip, allowing direct drive of a segment LCD without an external display controller.

What is the maximum operating frequency of MSP430F67681IPZ?

The core runs at 25 MHz, which is the maximum clock speed for this device.

What are the direct alternatives to MSP430F67681IPZ?

Within the MSP430F6xx series, pin-compatible siblings vary by Flash density (e.g., 256 KB vs 512 KB) and ADC channel count. The base product number MSP430F67681 identifies the 512 KB Flash, six-ADC variant; a lower-density sibling with fewer ADCs is the MSP430F6736. Confirm exact peripheral and memory requirements against the datasheet before substituting.
