Product details

Lifecycle reality — EOL, sourcing via independent channel

Key peripherals — LCD driver, 12-bit ADC, DMA

The integrated LCD driver can directly drive segmented glass displays, which is why this part appears in utility meters and portable medical readers. The 12-bit ADC with 12 analog inputs handles sensor conditioning without an external converter. DMA moves data between ADC, memory, and LCD without CPU intervention, keeping the 8 MHz core free for protocol handling and UI logic.

Packaging and mounting

Housed in an 80-lead LQFP (12x12 mm body), surface-mount. The 48 I/O lines give plenty of headroom for a parallel LCD data bus, keypad matrix, and sensor inputs in a single-layer routing board.

Frequently asked questions

What is the operating voltage range of MSP430F439IPNR?

The supply voltage range is 1.8 V to 3.6 V, allowing direct battery operation without an external regulator.

Is MSP430F439IPNR RoHS compliant and lead-free?

The MSP430F439IPNR is listed as RoHS compliant and lead-free per TI's standard green packaging for this order code.

What are the differences between MSP430F439IPNR and MSP430F437IPNR?

The MSP430F437IPNR has 48 KB Flash versus 60 KB on the F439; both share the same 80-LQFP package, 8 MHz core, and peripheral set. The F439 offers higher program memory density, but the two are not drop-in firmware replacements — the memory map and bootloader differ.

Where can I buy MSP430F439IPNR in small quantities?

We source the MSP430F439IPNR to order against an RFQ, including cut-tape or small-lot quantities. Availability and current pricing are confirmed at quote time through our independent supply chain.
