Product details

16-bit MCU with integrated analog front-end

The MSP430F6638IZCAT is a 16-bit microcontroller from the MSP430F6xx series, running at 20 MHz. It carries 256 KB of Flash program memory and 18K x 8 of RAM. The device integrates a 16-channel 12-bit ADC and a 2-channel 12-bit DAC, which reduces the external analog BOM for sensor interface or closed-loop control loops.

At 20 MHz the core delivers roughly 20 MIPS. The DMA engine offloads the core for background data movement.

Operates from 1.8 V to 3.6 V supply.

Frequently asked questions

What is the exact package code for MSP430F6638IZCAT?

The supplier device package is 113-NFBGA (7x7 mm), a 113-ball fine-pitch BGA.

What are the pin-compatible Flash upgrade options for MSP430F6638IZCAT?

Within the MSP430F6xx series, higher-density Flash variants in the same 113-NFBGA footprint are pin-compatible, allowing a BOM-level upgrade without a PCB spin.

What is the core voltage of MSP430F6638IZCAT?

The supply range is 1.8 V to 3.6 V, covering both 1.8 V and 3.3 V logic rails.
