MSP430F6776IPZR — 16-bit MCU with integrated 24-bit sigma-delta ADC for metering
An on-chip LCD driver supports segment displays common in utility meters and panel instruments.
The MSP430F6776IPZR carries an Obsolete lifecycle status. For an existing BOM line that already qualifies this MCU, the procurement path is the independent distribution market — surplus inventory, new-old-stock, or broker-sourced material.
The 7x24-bit sigma-delta ADC — why this MCU is different
The MSP430F6776IPZR carries seven independent 24-bit sigma-delta converters that can sample simultaneously, plus an 8x10-bit SAR ADC.
Package and temperature grade
Housed in a 100-pin LQFP with a 14x14 mm body, the MSP430F6776IPZR is a surface-mount device. It does not carry an AEC-Q100 automotive grade.
Connectivity and peripherals for a metering SoC
The brown-out detect and POR circuits are integrated, which saves an external supervisor IC. The DMA engine can move ADC results to RAM without CPU intervention, keeping the 25 MHz core free for the metrology algorithm and LCD refresh. Watchdog timer and PWM outputs round out the peripheral set for simple motor or valve control in a smart-meter or sub-meter application.
