MPN Structure

Artery MCUs follow a structure similar to STM32:

AT32[FAMILY][SERIES][VARIANT][PIN][FLASH][PKG][TEMP]
│      │       │       │       │     │      │     │
│      │       │       │       │     │      │     └── Temperature (6/​7)
│      │       │       │       │     │      └── Package (T=LQFP, U=QFN, H=BGA)
│      │       │       │       │     └── Flash size (4=16KB...M=4096KB)
│      │       │       │       └── Pin code (C=48, R=64, V=100, Z=144)
│      │       │       └── Optional variant (A, etc.)
│      │       └── Series number (403, 413, 415, 421, 435, etc.)
│      └── Family (F=MCU, WB=Wireless)
└── AT32 prefix

Handler Implementation Notes

Package Code Extraction

// Package type is 2nd from last character
// AT32F403AVCT7 -> T = LQFP
char packageChar = upperMpn.charAt(upperMpn.length() - 2);
String packageType = MCU_PACKAGE_CODES.get(packageChar);

// Combine with pin count for full package name
int pinCount = extractMCUPinCount(upperMpn);
return packageType + pinCount;  // e.g., "LQFP100"

Pin Count Extraction

// Pin code is 4th from last character
// AT32F403AVCT7 -> V = 100 pins
char pinCode = upperMpn.charAt(upperMpn.length() - 4);
Integer pinCount = MCU_PIN_COUNTS.get(pinCode);

Flash Size Extraction

// Flash code is 3rd from last character
// AT32F403AVCT7 -> C = 256KB
char flashCode = upperMpn.charAt(upperMpn.length() - 3);
Integer flashSize = MCU_FLASH_SIZES.get(flashCode);

Series Extraction

// AT32WB must be checked before AT32F
if (upperMpn.startsWith("AT32WB415")) return "AT32WB415";

// Standard series extraction
if (upperMpn.startsWith("AT32F403")) return "AT32F403";
if (upperMpn.startsWith("AT32F407")) return "AT32F407";
// etc.

Official Replacement Logic

// Same series AND same pin count = valid replacement
// Flash size, package type, and temperature can differ

String series1 = extractSeries(mpn1);
String series2 = extractSeries(mpn2);
if (!series1.equals(series2)) return false;

int pins1 = extractMCUPinCount(mpn1);
int pins2 = extractMCUPinCount(mpn2);
return pins1 == pins2;

STM32 Compatibility

Artery AT32 MCUs are designed as enhanced STM32-compatible alternatives:

Important: While register-compatible for most peripherals, always verify critical functionality when migrating from STM32.

Variant Suffixes

Some series have variant letters after the series number:

Learnings & Edge Cases

• Position-based extraction: Package at -2, flash at -3, pin at -4 from end
• 4MB Flash: AT32F435/​437 support M=4096KB, larger than most STM32
• AT32WB prefix: Wireless series uses WB instead of F in family position
• 240MHz+ clocks: Artery MCUs often have higher clock speeds than equivalent STM32
• Variant letter optional: AT32F403 and AT32F403A are different series
• Temperature 7 is extended: Goes to +105C vs standard industrial +85C
• STM32 migration: Pin-compatible but verify peripheral registers for critical functions
