TMS3637 Connector Pinout
TI recommends a ZIF socket to be used at location U14 for ease of programming the TMS3637. For
TMS3637P (DIP) packages, a 16-pin ZIF can be used (lower portion unused). For TMS3637N
surface-mount packages, use a clamshell with a latch cover and DIP footprint. This can be purchased from
EmMulation Technology (408-982-0660) part # AS-0808-015-3. The edge connector that is compatible with
the TMS3637 PCB is a Sullins part # EZC10DRTH or the equivalent as shown in Table 6–9. Ground
terminals A1, A6, and B1 are common, so only one is needed for ground connection.
