MSP430F67461IPZR — 16-bit metering MCU with integrated sigma-delta ADC and LCD drive
The Texas Instruments MSP430F67461IPZR is a 16-bit ultra-low-power MCU built around the MSP430 CPUXV2 core running at 25 MHz. It carries 256 KB of Flash program memory and 16K x 8 of RAM, with a rich peripheral set that includes four 24-bit sigma-delta analog-to-digital converters, an LCD driver, DMA, and a brown-out reset. The part is packaged in a 100-pin LQFP (14x14 mm) and is rated for industrial temperature operation from -40°C to 85°C.
What the 4x24b sigma-delta ADC and LCD driver mean for your BOM
Obsolete — last-time-buy window has closed
The MSP430F67461IPZR is officially classified as Obsolete by Texas Instruments. The last-time-buy period has passed, and no further factory orders are being accepted. Any available units are sourced through independent distribution channels, where date-code provenance and traceability should be verified. If you are refreshing an existing design, read the PCN before you buy — confirm your firmware image fits the exact die revision on hand.
Connectivity and I/O for system integration
With 62 I/O lines and support for I²C, SPI, UART/USART, IrDA, and LINbus, this MCU can interface to external EEPROM, serial displays, isolated transceivers, and sensor modules. The internal oscillator keeps the BOM lean for applications that do not require a precision external crystal, though the 25 MHz CPU speed benefits from a stable clock source for timing-critical sigma-delta conversions.
