Artery Technology MPN encoding patterns, suffix decoding, and handler guidance. Use when working with Artery AT32 MCUs (STM32-compatible ARM Cortex-M4) or ArteryHandler.
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
AT32F403AVCT7
│ │ │ ││││
│ │ │ │││└── Temp 7 (industrial extended, -40 to +105C)
│ │ │ ││└── Package T (LQFP)
│ │ │ │└── Flash C (256KB)
│ │ │ └── Pin V (100-pin)
│ │ └── Variant A
│ └── Series 403 (high performance)
└── F = MCU family
AT32WB415CCU6

│ │ │└── Package U (QFN)
│ │ └── Flash C (256KB)
│ └── Pin C (48-pin)
└── WB415 = Wireless (Bluetooth LE)

manufacturers/ArteryHandler.javaMICROCONTROLLER, ICArtery AT32 MCUs are designed as enhanced STM32-compatible alternatives:
| AT32 Series | STM32 Equivalent | Advantages |
|---|---|---|
| AT32F403A | STM32F103 | Higher clock (240 vs 72MHz) |
| AT32F407 | STM32F107 | Higher clock, more Flash |
| AT32F413 | STM32F103 | Better price/performance |
| AT32F415 | STM32F105 | USB OTG compatible |
| AT32F421 | STM32F030 | Cortex-M4 vs M0 |
| AT32F435/437 | STM32F4xx | Up to 4MB Flash |
Important: While register-compatible for most peripherals, always verify critical functionality when migrating from STM32.
Some series have variant letters after the series number:
| Variant | Meaning |
|---|---|
| A | Enhanced version (e.g., AT32F403A) |
| (none) | Standard version |
