Product details

8 MHz mixed-signal MCU with LCD drive and data converters

It packs 32 KB of program Flash and 1K x 8 of RAM, along with an integrated 12-channel 12-bit ADC and dual 12-bit DACs — a signal-chain MCU that handles sensor conditioning and control without external converters. Housed in an 80-LQFP (12x12 mm) package with 48 I/O, it targets industrial instrumentation, metering, and portable medical devices where the combination of low power, mixed-signal integration, and a direct-drive LCD segment interface reduces BOM count.

For production BOMs that need a 16-bit mixed-signal MCU with LCD drive, this part remains a current-design choice without the sourcing risk of a phase-out component.

Frequently asked questions

What is the difference between MSP430FG437IPN and MSP430FG437IPNR?

The difference is packaging and shipping medium. The MSP430FG437IPN ships in a tray; the MSP430FG437IPNR suffix typically indicates tape-and-reel packaging. Electrically and functionally they are identical. When ordering, confirm the packaging format your assembly line requires.

What is the MSP430FG437IPN's core speed and Flash size?

The MSP430FG437IPN runs at 8 MHz and provides 32 KB of program Flash (32K x 8 plus 256 bytes of information memory).
