MPN Structure
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)
Example Decoding
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
Series Prefixes
| Prefix | Category | Description | |--------|----------|-------------| | P25Q | Standard SPI NOR Flash | 3.3V operation, general purpose | | P25D | Low Power SPI NOR Flash | Reduced power consumption | | PY25Q | Automotive Grade SPI NOR Flash | AEC-Q100 qualified, extended temperature |
Density Codes
| Code | Density | Size | |------|---------|------| | 80 | 8 Mbit | 1 MB | | 16 | 16 Mbit | 2 MB | | 32 | 32 Mbit | 4 MB | | 64 | 64 Mbit | 8 MB | | 128 | 128 Mbit | 16 MB |
Note: Density code 80 represents 8 Mbit (not 80 Mbit).
Package Codes
Base Package Codes
| Code | Package | Notes | |------|---------|-------| | H | SOIC-8 | Standard 208mil body | | U | USON-8 | Ultra thin 2x3mm | | SH | SOIC-8-WIDE | Wide body 300mil | | SU | WSON-8 | 6x5mm leadless |
Hyphenated Suffix Codes
| Suffix | Package | Notes | |--------|---------|-------| | -SSH | SOIC-8 | Standard SOIC-8 with grade indicator | | -SUH | WSON-8 | WSON-8 with grade indicator |
Product Families
P25Q Series - Standard SPI NOR Flash
| Part Number | Density | Interface | Voltage | Speed | |-------------|---------|-----------|---------|-------| | P25Q80H | 8 Mbit | SPI/Dual/Quad | 2.3V-3.6V | 104MHz | | P25Q16H | 16 Mbit | SPI/Dual/Quad | 2.3V-3.6V | 104MHz | | P25Q32H | 32 Mbit | SPI/Dual/Quad | 2.3V-3.6V | 104MHz | | P25Q64H | 64 Mbit | SPI/Dual/Quad | 2.3V-3.6V | 104MHz | | P25Q128H | 128 Mbit | SPI/Dual/Quad | 2.3V-3.6V | 104MHz |
P25D Series - Low Power SPI NOR Flash
| Part Number | Density | Interface | Voltage | Power Mode | |-------------|---------|-----------|---------|------------| | P25D80H | 8 Mbit | SPI/Dual/Quad | 1.65V-3.6V | Ultra Low Power |
PY25Q Series - Automotive Grade SPI NOR Flash
| Part Number | Density | Temperature | Qualification | |-------------|---------|-------------|---------------| | PY25Q128HA | 128 Mbit | -40C to +125C | AEC-Q100 |
Handler Implementation Notes
Pattern Matching
// P25Q series - Standard SPI NOR Flash
"^P25Q\\d+.*"
// P25D series - Low Power SPI NOR Flash
"^P25D\\d+.*"
// PY25Q series - Automotive Grade (check first as more specific)
"^PY25Q\\d+.*"
Package Code Extraction
// Handle hyphenated suffixes first
int hyphenIndex = upperMpn.indexOf('-');
if (hyphenIndex > 0) {
String suffix = upperMpn.substring(hyphenIndex + 1);
// Check against PACKAGE_CODES map
}
// Then extract trailing package code after density
// P25Q80H -> H (SOIC-8)
// Check longer suffixes before shorter ones (SU before U, SH before H)
Density Extraction
// Special case: 80 = 8Mbit, not 80Mbit
switch (densityCode) {
case "80" -> "8";
default -> densityCode;
}
Grade Extraction
// Check prefix to determine grade
if (upperMpn.startsWith("PY25Q")) return "Automotive";
if (upperMpn.startsWith("P25D")) return "Low Power";
if (upperMpn.startsWith("P25Q")) return "Standard";
Cross-References
Puya Flash is pin-compatible with other SPI NOR Flash manufacturers:

Learnings & Edge Cases
- Density code 80: Represents 8 Mbit, not 80 Mbit - special handling required
- PY vs P prefix: PY25Q is automotive grade, must check before P25Q pattern
- Hyphenated suffixes: Some MPNs have package code after hyphen (P25Q16H-SSH)
- Grade indicators: Trailing 'A' often indicates automotive grade
- Pin compatibility: Puya Flash is generally pin-compatible with Winbond, GigaDevice, and Macronix equivalents
