The 66K x 8 of RAM (about 66 KB) is generous for a 16-bit part — enough for large data buffers or a modest frame buffer for a small display. No EEPROM is on-chip, but the Flash can be used for non-volatile storage with wear-leveling. ## USB 2.0-compatible full-speed device Texas Instruments has marked the MSP430F5659IZQWR as obsolete. No official successor part number has been published for this exact BGA variant. If you need a drop-in replacement, check the MSP430F5xx family for a pin-compatible alternative with similar Flash and RAM; the datasheet pinout is shared across several density options in the same BGA footprint. The 113-ball BGA Microstar Junior (7x7 mm) is a fine-pitch BGA — not something you can hand-solder with a standard iron. It requires a reflow oven, a solder stencil, and a PCB with microvias or at least via-in-pad capability. The 74 I/O lines give plenty of GPIO for parallel LCDs, keypads, or memory expansion, but every trace out of that BGA needs careful fanout planning. If you're a maker or hobbyist, this package is a tough sell for a breadboard project; look for a TQFP-packaged sibling in the same family instead.","metaTitle":"TI MSP430F5659IZQWR 16-bit MCU, 20MHz, 512KB Flash, 113-BGA","metaDescription":"Texas Instruments MSP430F5659IZQWR 16-bit MCU with 20MHz CPU, 512KB Flash, 66K RAM, USB, 12-bit ADC/DAC.
