This is the part you pick when you need USB connectivity in a battery-powered or industrial sensor node without adding a second chip. ## 256 KB Flash / 18 KB RAM — firmware headroom With 256 KB of Flash and 18 KB of RAM, this MCU sits in the middle of the F6xx density range. That is enough space for a USB composite device (HID + CDC) with a modest control loop, a data-logging buffer, and a bootloader. The RAM is tight if you plan to double-buffer USB packets and run a large display buffer — budget carefully. The Flash endurance is rated for 100k write/erase cycles per sector, typical for MSP430, so wear-leveling is not critical unless you are logging configuration changes every few seconds. ## 113-NFBGA (7x7 mm) — layout and reflow The 113-NFBGA package measures 7x7 mm with a 0.5 mm ball pitch. That is a fine-pitch BGA — you need a solder stencil, a reflow oven, and X-ray inspection to verify joints. No field-swapping this one with a soldering iron; plan for a rework station if you are supporting field returns. The 74 I/O count gives plenty of GPIO for a keypad, display, and sensor interface, but every signal is on a BGA ball — route the breakout fan-out carefully in the first two layers.","metaTitle":"TI MSP430F6635IZCAR 16-bit MCU, 20MHz, 256KB Flash, USB 2.0","metaDescription":"Texas Instruments MSP430F6635IZCAR 16-bit MCU with 20MHz MSP430 CPUXV2, 256KB Flash, 18KB RAM, integrated USB 2.0 PHY.

The MSP430F6635IZCAR comes in a 113-NFBGA (7x7 mm) package, while the MSP430F6635IPNR is in a 80-LQFP (12x12 mm) package. The LQFP variant is easier to hand-solder and inspect, but the BGA variant offers a smaller footprint and potentially better thermal performance. Both share the same core, memory, and peripheral set."},{"question":"Is MSP430F6635IZCAR compatible with USB 2.0?","answer":"Yes, the MSP430F6635IZCAR integrates a full-speed USB 2.0 PHY.
