Manufactured by Kiwi Instruments, the KP18002ESPA is housed in a ESOP-8 package with 9 pins and a 1.27 mm lead pitch. Key pins include: 1 (NC: Multiplexed I/O & Peripheral Pin NC (General)), 2 (NC: Multiplexed I/O & Peripheral Pin NC (General)), 3 (NC: Multiplexed I/O & Peripheral Pin NC (General)), 4 (OUT: Multiplexed I/O & Peripheral Pin OUT (General)), 5 (NC: Multiplexed I/O & Peripheral Pin NC (General)), 6 (CS: Multiplexed I/O & Peripheral Pin CS (General)).
Normalized from the official datasheet mechanical drawing per IPC-7351B (Density Level B Nominal), KP18002ESPA (ESOP-8) has a nominal body envelope of 3.90 × 4.90 mm, pitch e = 1.27 mm, and 9 copper pads plus a central exposed thermal pad (EPAD) of 2.40 × 3.30 mm with a 60% IPC-7525 windowed solder paste grid.
