The 18 KB RAM is sufficient for double-buffered USB transfers, sensor data logging, and communication protocol state machines. The Flash is organized as 192 KB × 8 bits; the RAM as 18 K × 8 bits. For firmware updates over USB, the on-chip bootloader (BSL) supports field reprogramming without a dedicated programmer. Housed in a 100-pin LQFP with a 14 mm × 14 mm body (0.5 mm pitch), the MSP430F5637IPZ is surface-mount and hand-solderable with standard reflow profiles. The 74 I/O lines are distributed across the four sides, which simplifies fan-out on a two-layer board for many designs. The supplier device package code is 100-LQFP (14x14). This footprint is shared across the MSP430F5xx 100-pin LQFP variants, so a board layout can accommodate multiple Flash/RAM density options with a single PCB spin.","metaTitle":"TI MSP430F5637IPZ 16-bit MCU, 20MHz, 192KB Flash, USB","metaDescription":"Texas Instruments MSP430F5637IPZ 16-bit MCU with MSP430 CPUXV2 core at 20MHz, 192KB Flash, 18KB RAM, USB 2.0, 74 I/O.

The key difference is Flash and RAM: the F5637 offers 192 KB Flash and 18 KB RAM, while the F5638 doubles the Flash to 256 KB and increases RAM to 18 KB as well. Both share the same 20 MHz core, USB interface, 74 I/O, and pinout, so a board designed for one can accept the other with a firmware change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/MSP430F5637IPZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/MSP430F5637IPZ when reusing this data.
