The MSP430F67471IPEUR integrates four 24-bit sigma-delta ADCs and an LCD driver.
Four 24-bit sigma-delta converters and an LCD driver with charge pump are integrated.
The 128-LQFP package is 20 mm x 14 mm with 90 I/O pins.
The two parts share the same base product number MSP430F67471, indicating identical core, memory, and peripheral configuration. The difference is in the suffix: IPEUR is the 128-LQFP package variant, while IPZR is a different package option. Both are obsolete. Verify the specific package code against your PCB footprint before ordering.
No. The part is obsolete, so it is not recommended for new designs. For a new production run, select an active MSP430F6xx or MSP430FRxx metering MCU from TI's current portfolio.
The core processor runs at 25 MHz. This is the maximum clock speed for the MSP430 CPUXV2 core in this device.
