Puya MPNs follow this general structure:
[PREFIX][DENSITY][PACKAGE][-SUFFIX]
| | | |
| | | +-- Optional: Grade/Temperature (SSH, SUH)
| | +-- Package code (H, U, SH, SU)
| +-- Memory density (80=8Mbit, 16, 32, 64, 128)
+-- Series prefix (P25Q, P25D, PY25Q)
P25Q80H
| | ||
| | |+-- H = SOIC-8 package
| | +-- 80 = 8 Mbit density
| +-- Q = Standard series
+-- P25 = Puya SPI Flash prefix
P25Q16H-SSH
| | | | |
| | | | +-- SSH = SOIC-8 (hyphenated suffix)
| | | +-- H = base package indicator
| | +-- 16 = 16 Mbit density
| +-- Q = Standard series
+-- P25 = Puya SPI Flash prefix
PY25Q128HA
| | | ||
| | | |+-- A = Grade code (Automotive)
| | | +-- H = SOIC-8 package
| | +-- 128 = 128 Mbit density
| +-- Y25Q = Automotive grade series
+-- P = Puya prefix
