The 10 KB RAM is shared between stack, heap, and data buffers; designs that need large circular buffers or multiple DMA descriptors should budget carefully. The Flash is field-reprogrammable, which supports firmware updates in the field if the bootloader fits within the remaining space. ## 80-BGA MICROSTAR JUNIOR — board-assembly constraints The 80-ball VFBGA package measures 5×5 mm. This fine-pitch BGA requires X-ray inspection for voids and shorts. ## Obsolete — last-time-buy sourcing only Texas Instruments has marked the MSP430F5522IZQER as obsolete. No further factory orders are being accepted, and no official successor part number has been published for this specific package variant. For new designs, consider the active MSP430F5xx family members in LQFP packages, which offer similar peripheral sets and are easier to source. ## Industrial temperature grade — field deployment envelope","metaTitle":"TI MSP430F5522IZQER 16-bit MCU, 25 MHz, 32 KB Flash, 80-BGA","metaDescription":"Texas Instruments MSP430F5522IZQER 16-bit MCU with MSP430 CPUXV2 core at 25 MHz, 32 KB Flash, 10 KB RAM, 47 I/O, 12-bit ADC, industrial temp -40°C to 85°C.
