It packs 192KB of Flash and 18KB of RAM, with an integrated USB 2.0 device controller — enough memory and peripheral mix to handle a medium-complexity embedded application without external storage. On-chip analog includes a 16-channel 12-bit ADC and a 2-channel 12-bit DAC, so sensor conditioning and closed-loop control can stay on a single die. The 74 general-purpose I/O lines provide enough headroom for a parallel LCD bus, keypad matrix, and a handful of external interrupts. ## Supply range, temperature grade, and package Housed in the 113-ball VFBGA Microstar Junior package (7x7mm), the 0.50mm pitch demands a multi-layer PCB for fan-out. The small footprint is a trade-off — you save board area but need a controlled-impedance stack-up to route the USB differential pair cleanly. Texas Instruments lists the MSP430F5637IZQWR as Obsolete. The part is sourced through independent distribution against an RFQ — quantities are lot-specific and confirmed at quote time. For a BOM that already qualifies this MCU, the procurement risk is manageable: the part is still available on the surplus market, but the window is closing. Any new design should migrate to a current MSP430F5xx or MSP430F6xx variant with a compatible peripheral set.","metaTitle":"Texas Instruments MSP430F5637IZQWR 16-bit MCU, 20MHz","metaDescription":"Texas Instruments MSP430F5637IZQWR MSP430F5xx 16-bit MCU, 20MHz, 192KB Flash, 18KB RAM, USB 2.0, 74 I/O, 113-BGA.
